JP 2004-15149 A

  An embodiment having the above-described structure will be described with reference to FIGS. FIG. 16 is a diagram showing an embodiment of a conventional in-vehicle electronic device. FIG. 17 is a diagram illustrating a state in which the in-vehicle electronic device illustrated in FIG. 16 is mounted in the vehicle.

  As shown in FIG. 16, in one embodiment of a conventional in-vehicle electronic device, an operation panel 72 having operation keys and display devices is attached to the front surface of the housing 70, and a slit opening on the top surface of the housing 70. 70a is provided, and the speaker 2 is attached inside the slit 70a. In the slit 70a, a plurality of flaps 70b are formed by extending in the front direction of the housing 70 to which the operation panel 72 is attached. In one embodiment of the conventional in-vehicle electronic device having such a configuration, the speaker 2 is arranged on the top surface in the housing 70 to secure the arrangement space for the operation panel 72 on the front surface. The area where the operation keys and the display unit are arranged can be secured widely, and the visibility and operability are improved. Further, the high directivity sound radiated from the speaker 2 is reflected by the flap 70b and emitted toward the front surface of the operation panel 72 (dotted line shown in FIG. 16). High-frequency and low-frequency sounds can be radiated toward the user who is present, making it easier to identify speech even in noisy environments.

  However, in the embodiment of the conventional vehicle-mounted electronic device, the speaker 2 is fixed to the top surface of the housing 70, and therefore, as shown in FIG. When installed on the lower surface of the installation section 1 such as the above, the top surface of the housing 70 is blocked, and the radiation of high and low frequency sounds becomes insufficient, resulting in restrictions on the installation location and free installation. There was a bug that it was not possible.

Further, unlike the above-described structure, as another embodiment of the conventional in-vehicle electronic device, there is an in-vehicle electronic device in which the operation panel 72 is provided so as to be detachable from the housing 70. FIG. 18 is a view showing another embodiment of a conventional in-vehicle electronic device in which the operation panel 90 is detachable as described above. FIG. 18A is an example in which the speaker 2 is provided in the operation panel 90. FIG. 18B shows an embodiment in which the speaker 2 is provided in the housing 80.
As shown in FIG. 18, in another embodiment of a conventional in-vehicle electronic device, a casing 80 and an operation panel 90 are provided separately, and a jack 91 a is provided at the tip of a cable 91 extending from the operation panel 90. The jack 91a is inserted into the connector 86 on the front surface of the housing 80 so as to be electrically connected. In addition, when the casing 80 is a wireless device, for example, a microphone connector 88 is provided on the front surface from which the operation panel 90 is removed, and the microphone 81 is connected by inserting a microphone jack 81b at the tip of a cable 81a extending from the microphone 81. It is formed so that it can be done. However, in another embodiment of such a conventional in-vehicle electronic device, for example, if the sound quality and the sound pressure are emphasized so as not to be blocked like the restriction on the top surface described above, FIG. As shown in FIG. 2, this can be dealt with by providing a sound radiation hole 90b on the front surface of the operation panel 90 and disposing a speaker (not shown) therein. In this case, however, the space for disposing the operation panel 90 is reduced. Will be sacrificed. On the other hand, if the operability is regarded as important, as shown in FIG. 18B, in order to secure a wide arrangement space on the front surface of the operation panel 90, the radiation hole 80b is formed on the outer surface (for example, the top surface) of the casing 80. In the end, as with the in-vehicle electronic device shown in FIG. 17, the sound quality and the sound pressure are sacrificed due to the restrictions on the installation location. Furthermore, in order to obtain the optimum directivity of the speaker, there is a method of externally attaching an external speaker (not shown) like the microphone 81, but it is necessary to secure a new installation place and cost in the vehicle, which burdens the user. Become more.

Thus, in the conventional in-vehicle electronic device, as shown in FIG. 17, the casing 70 provided with the slit 70 a of the speaker 2 on the top surface is provided on the lower surface of the installation portion 1 such as a dashboard or a table in the vehicle. When installed, the slit 70a provided on the top surface of the housing 70 is blocked by the lower surface of the installation unit 1, and the sound emission in the high and low ranges becomes insufficient, so that the installation location can be restricted and freely set. There was a problem that it could not be placed.
Also, in the conventional in-vehicle electronic device, as shown in FIG. 18, sound quality and sound pressure are sacrificed when operability is regarded as important, and operability is sacrificed when sound quality and sound pressure are regarded as important. However, there is a problem that operability, sound quality, and sound pressure cannot be compatible, and as a result, they cannot be used properly according to the installation location and the use environment.
In addition, in conventional in-vehicle electronic devices, there is a method of newly arranging external speakers in order to obtain optimal speaker directivity. However, in this case, it is necessary to secure a new installation place and cost, and burden the user. Become more.

  The present invention has been made in view of the above points, and its purpose is to freely change the directivity of the speaker according to the installation location and use environment of the casing, and to use it with a simple structure.

It is preferable to provide the speaker holder via a gear in conjunction with the vertical movement when the operation panel is attached / detached. In another embodiment of the case, a slider that supports the operation panel and protrudes and protrudes on the front surface is provided, and the operation panel is detachably provided when the slider protrudes. It is preferable to provide the speaker holder so as to rotate in conjunction with the operation. Further, the speaker holder is preferably rotated to the top surface of the housing when the operation panel is attached and to the front surface of the housing when the operation panel is removed, thereby changing the directivity of the sound of the speaker. Further, another embodiment of the speaker holder may be provided so as to be selectively operated and rotated by an operating means such as a switch or button provided on the casing or the operation panel according to the installation situation of the casing. preferable. The housing preferably has a sound radiation hole on at least two outer surfaces including a front surface on which the operation panel is attached and detached, and is provided so that the speaker holder rotates in the vicinity of the radiation hole on each surface. .

As described above, according to the in-vehicle electronic device according to the present invention, the directivity can be changed in a desired direction by attaching and detaching the panel and rotating the speaker even after the housing is installed. It is possible to reduce the restrictions on the installation location and propose an optimum use environment.
In addition, according to the vehicle-mounted electronic device according to the present invention, since the directivity can be changed by rotating the speaker on two or more surfaces including the front surface of the housing to which the operation panel is attached and detached, the housing is installed in the vehicle. Even if a given surface is sometimes blocked, the directivity can be changed by rotating the speaker to another surface, and both operability and sound quality and pressure can be achieved. It can be used properly according to the usage environment.
In addition, according to the in-vehicle electronic device of the present invention, it is not necessary to arrange an external speaker in order to obtain optimum speaker directivity, and it is easy for the user because a new installation place and cost are not required.

The sound directivity can be changed by selectively rotating 12 according to the installation state of the housing 10. That is, the present invention is provided on the premise that the operation panel 20 is detachably provided as in the prior art shown in FIG. 18, and the operation panel 20 is relatively small and less restricted on the outer surface of the housing 10. The directivity of the speaker 2 can be changed between when the operation panel 20 is attached to the housing 10 and when it is removed.

  Here, the housing 10 has a sound radiation hole 10b on the outer surface of the front surface and the top surface to which the operation panel 20 is attached and detached, and the speaker holder 12 is disposed close to the inside of the radiation hole 10b on each surface. It is provided to rotate. In addition, the housing 10 is integrally formed with fitting slits 10a having a U-shaped cross section at both ends of the front surface to which the operation panel 20 is attached and detached and extending in a rail shape up and down. Further, the operation panel 20 is integrally formed with a fitting rib 20a that is inserted into the fitting slit 10a of the housing 10 from the upper end and supported so as to be movable up and down. Accordingly, the housing 10 is provided so that the operation panel 10 can be attached to and detached from the front surface by fitting or removing the fitting rib 20a of the operation panel 20 from the upper end of the fitting slit 10a. At this time, as shown in FIG. 2, the operation panel 20 has an elastic portion 20b having elasticity at the center of the back surface and extending like a plate, and an engagement claw 20c protruding from the elastic portion 20b to the back surface side.

Further, the casing 10 is provided with a stopper claw 10c that protrudes from the front surface shown in FIG. 1, and the operation panel 20 is lowered to the lower end along the fitting slit 10a, so that the stopper claw 10c and the engagement claw are lowered. 20c is engaged with each other so that the operation panel 20 can be locked to the front surface. Then, as in the prior art shown in FIG. 18, the operation panel 20 extends the cable 21 and inserts the jack 21a at the tip into the connector 16 (see FIG. 8A) of the housing 10, thereby It is formed so that it can be electrically connected to the body 10. Moreover, when the housing | casing 10 is a radio | wireless machine, for example, the microphone jack 11b (refer FIG. 8A) of the cable 11a extended from the microphone 11 is inserted in the microphone connector 18 of the housing | casing 10, The microphone 11 is formed so that it can be externally attached.

By the way, the operation panel 20 is not limited to integrally forming the elastic portion 20b having the engagement claw 20c on the back surface shown in FIG. 2, and can be slid separately from the operation panel 20, for example. It is also possible to provide the sliding body in a state of being biased to the back side. As shown in FIG. 3, another embodiment of such an operation panel 30 is separately supported at the center of the upper end so as to be slidable in the front-rear direction (the arrow direction shown in FIG. 3), and is elastic such as a spring. A sliding body 32 urged so as to protrude rearward by a body (not shown) is provided. Similar to the elastic portion shown in FIG. 2, the sliding body 32 is integrally formed with an engaging claw 32 a that protrudes on the back side of the operation panel 30, and engages with the stopper claw 10 c of the housing 10 to engage with the operation panel 30. Is provided to lock.
Further, the housing 10 is not limited to the formation of the stopper claw 10c protruding in the center of the front surface as shown in FIG. 1, but as another embodiment, for example, as shown in FIG. By providing a lock recess 40c that is recessed in the front surface of the body 40, it is possible to insert the engagement claws 20c and 32a shown in FIGS. 2 and 3 so as to lock the operation panels 20 and 30. .

  Further, the operation panel 20 is integrally formed with a gear engaging portion 20d extending in a rack shape on one side of the back surface provided with the elastic portion 20b shown in FIG. On the other hand, the housing 10 is provided with a gear 14 that is supported so as to partially protrude from the front surface shown in FIG. 1, and is arranged so as to be engaged with the gear engaging portion 20d described above. ing. The gear 14 is formed to engage with the speaker holder 12 in the housing 10 and rotate. That is, in the case 10, the operation panel 20 is supported on the front face so as to be movable up and down, and the gear engaging portion 20d of the operation panel 20 is engaged with the speaker holder 12 supported inside via the gear 14 to operate the operation panel. When the panel 20 is pushed up to the upper end of the housing 10, the gear 14 is disengaged and the operation panel 20 can be detached, and the speaker via the gear 14 is interlocked with the vertical movement when the operation panel 20 is detached. The holder 12 is provided so as to rotate. Therefore, the speaker holder 12 is provided so as to rotate (see FIG. 7) in conjunction with the operation when the operation panel 20 is selectively detached from the housing 10 according to the installation state of the housing 10. .

  Here, as shown in FIG. 5, the speaker holder 12 has a body 12 a that extends in a columnar shape and is hollow inside and can accommodate the speaker 2, and a pivot shaft that protrudes in a rod shape at the center of both ends of the body 12 a. 12b, and is rotatably supported by the rotation shaft 12b in the housing 10 (see FIG. 1). Further, the speaker holder 12 is integrally formed with a gear connecting portion 12c formed in a gear shape on one side of the rotating shaft 12b protruding from both ends of the body 12a, and the gear connecting portion 12c has the gear shown in FIG. 14 is engaged so as to rotate within the housing 10. The speaker holder 12 has a radiation hole 12d that penetrates from the inside to the outside so that the speaker 2 housed in the body 12a radiates sound. As shown in FIG. 6, the speaker holder 12 formed in this way is arranged in the housing 10 so as to be close to the radiation holes 10 b on each surface (the front surface and the top surface in FIG. 6). 12d is formed so as to rotate in accordance with the radiation hole 10b opened on each surface of the housing 10. That is, for example, in the case of the case 10 in which the radiation hole 10b is provided in the front surface and the top surface shown in FIG. 6, the speaker holder 12 is approximately 90 ° in accordance with the radiation hole 10b between the front surface and the top surface. It is provided to rotate at a rotation angle.

  Next, with reference to FIG. 7 and FIG. 8, the operation | movement using 1st Embodiment of the vehicle-mounted electronic device by this invention formed in this way is demonstrated in detail. In the first embodiment of the on-vehicle electronic device according to the present invention, as shown in FIG. 7, the vertical movement when the operation panel 20 is attached / detached is the rotational movement of the speaker holder 12 via the gear 14 of the housing 10. It is made to work. Specifically, first, as shown in FIG. 7A, when the operation panel 20 is removed from the housing 10, the radiation hole 12d of the speaker holder 12 shown in FIG. The directivity of 2 is also set to face the front side of the housing 10. Therefore, as shown in FIG. 8A, even if the casing 10 is installed on the lower surface of the installation unit 1 such as a dashboard or a table in the vehicle and the top surface is blocked, the operation panel 20 is removed from the casing 10. When the speaker 2 is removed, the speaker 2 rotates and faces the front surface, so that sufficient sound quality and sound pressure can be obtained from the front surface. In addition, since the operation panel 20 is connected to the housing 10 via the cable 21 and can be freely moved, the operation panel 20 can be installed at a place desired by the user.

  On the other hand, when the housing 10 is placed on the top surface as shown in FIG. 8B instead of the lower surface of the installation unit 1, it can be dealt with by mounting the operation panel 20 on the front surface of the housing 10. Here, when used by placing on the top surface, sufficient sound quality and sound pressure can be obtained from the front surface of the housing 10 even if the operation panel 20 is removed from the housing 10 shown in FIG. For example, the following description will be made on the assumption that the operation panel 20 is mounted on the front surface of the housing 10 so that a separate space is not required. First, from the state in which the operation panel 20 shown in FIG. 7A is removed, as shown in FIG. 7B, the operation panel 20 is inserted from the upper end of the front surface of the housing 10 so that no additional space is required.

At this time, as shown in FIG. 1, the operation panel 20 can be easily mounted on the front surface of the housing 10 by inserting the fitting rib 20 a along the fitting slit 10 a of the housing 10. . When the fitting rib 20a of the operation panel 20 is fitted and fitted into the fitting slit 10a of the housing 10 as described above, the gear engaging portion 20d of the operation panel 20 is attached to the housing 10 as shown in FIG. While rotating the gear 14, the gear 14 rotates the gear connecting portion 12 c that moves integrally with the speaker holder 12. When the operation panel 20 is lowered and attached to the front surface of the housing 10 as shown in FIG. 7D, the speaker holder 12 rotates and the directivity of the speaker 2 is set to the top surface side of the housing 10. Can be set to face. That is, it is possible to provide the user with optimum sound quality and sound pressure by recognizing the installation state of the housing 10 as shown in FIG. 8 and changing the directivity of the speaker 2.

  When the operation panel 20 is attached to the housing 10 as shown in FIG. 7D, the engaging claw 20c shown in FIG. 2 is engaged with the stopper claw 10c of the housing 10 shown in FIG. At the same time, the housing 10 is locked so as not to be removed by sliding up and down. When the operation panel 20 is removed from the housing 10 again, the engagement between the engagement claw 20c and the stopper claw 10c is achieved by pressing the elastic portion 20b shown in FIG. Can be easily removed by pushing up the operation panel 20. At this time, the speaker holder 12 rotates in the direction opposite to the operation shown in FIG. 7 in conjunction with the operation of pushing up the operation panel 20, and operates so that the speaker 2 facing the top surface faces the front surface. . That is, the speaker holder 12 rotates to the top surface of the housing 10 when the operation panel 20 is attached, and to the front surface of the housing 10 when the operation panel 20 is detached, and the sound directivity of the speaker 2 is interlocked with the attachment / detachment. Can be changed. Therefore, as shown in FIG. 8A, the radiation hole 10b on the top surface of the housing 10 is not clogged with the lower surface of the installation part 1, and can be freely attached to the installation part 1, Smart installation is possible.

As described above, according to the first embodiment of the in-vehicle electronic device according to the present invention, the directivity can be changed to the front surface or the top surface by removing the panel 20 and rotating the speaker 2 even after the housing 10 is installed. Therefore, the housing 10 can be freely arranged, and the restriction of the installation location is reduced, and an optimum use environment can be proposed.
Further, according to the first embodiment of the in-vehicle electronic device according to the present invention, the directivity can be changed by attaching and detaching the operation panel 20 and rotating the speaker 2 to the front surface or the top surface of the housing 10. Even if the top surface is blocked when the housing 10 is installed in the installation section 1 in the car, the directivity can be freely adjusted by rotating the speaker 2 to the front, and both operability, sound quality and sound pressure can be achieved. In almost any place, it can be used properly according to the installation location and usage environment.
In addition, according to the first embodiment of the in-vehicle electronic device according to the present invention, it is not necessary to separately arrange an external speaker in order to obtain the optimum directivity of the speaker, and it is not necessary to secure a new installation place or cost. User friendly.

  Next, another embodiment in which the speaker holder 12 is rotated by a slider without using the gear 14 shown in FIG. 1 will be described in detail. As shown in FIG. 9, the second embodiment of the in-vehicle electronic device according to the present invention using the slider as described above includes a housing 50, an operation panel 60 that is attached to and detached from the front surface of the housing 50, and a housing 50 is provided with a speaker holder 52 (see FIGS. 10 and 11) that holds the speaker 2 and is rotatably supported. Similar to the first embodiment, the operation panel 60 is formed so as to be electrically connected to the housing 50 by extending the cable 61 and inserting the jack 61a at the tip into the connector 56 of the housing 50. ing. Further, when the housing 50 is a wireless device, for example, the microphone 51 can be externally attached by inserting the microphone jack 51b at the tip of the cable 51a extending from the microphone 51 into the microphone connector 58 of the housing 50. Is formed. Here, the housing 50 is provided with a slider 54 that supports the operation panel 60 and protrudes from the front surface. When the slider 54 protrudes, the operation panel 60 is detachably provided. The speaker holder 12 (see FIGS. 10 and 11) is configured to rotate in conjunction with the accompanying movement of the slider 54.

  Here, the slider 54 is formed in a plate shape and is disposed so as to protrude vertically from the inside of the housing 50 to the front surface, and engages with a driving source such as a motor within the housing 50. It is provided so as to appear in front and back through the front. Further, as shown in FIG. 10, the slider 54 is formed in a circular arc shape so that an end portion extending in a plate shape inside the housing 50 gradually spreads from the upper part toward the lower part. On the other hand, as shown in FIG. 11, the speaker holder 52 is cylindrical and is provided so that the speaker 2 (see FIG. 10) can be accommodated in the hollow, and is supported in the housing 50 by rotating shafts 52b provided at both ends. Yes. The speaker holder 52 is separated from one side of the rotation shaft 52b provided at both ends, not on the gear connecting portion shown in FIG. 5, but on the outside centered on the rotation shaft 52b as shown in FIG. A guide pin 52c that is provided and that protrudes and rotates in a bar shape in parallel with the rotation shaft 52b is integrally formed. Although not shown, the speaker holder 52 is urged by an elastic member such as a spring so that the speaker 2 always faces the front surface in the housing 50 (in the state shown in FIG. 10). As shown in FIG. 10, the guide pin 52 c is disposed so as to operate in contact with the arcuate end portion of the slider 54 in the housing 50. That is, when the slider 54 is protruded from the front surface of the housing 50, the speaker holder 52 is urged by an elastic member to rotate the speaker 2 to a position where the speaker 2 always faces the front surface, and the slider 54 is moved into the housing 50. When housed, the guide pin 52c is pushed up by the end cut out in an arc shape, and the speaker 2 is rotated so as to face the top surface.

  By the way, the embodiment in which the speaker holder 52 is urged by an elastic member so that the speaker 2 always faces the front side has been described in detail. However, the present invention is not limited to this. For example, as shown in FIG. It is also possible to eliminate the need for an elastic member by forming a guide hole 55a that is elongated in the side surface of the slider 55, and inserting and engaging the guide pin 52c in the guide hole 55a. Here, the guide hole 55a is opened by being curved in an arc shape in the vertical direction perpendicular to the sliding direction that appears before and after the slider 55, and the guide pin 52c is moved in the arc shape as the slider 55 slides. The speaker holder 52 can be rotated by guiding it up and down along the hole. In another embodiment of the slider 55, since the guide pin 52c is guided along the guide hole 55a to rotate the speaker holder 52, the same effect as the slider shown in FIG. 10 can be obtained. It is not necessary to use complicated parts such as a gear or an elastic member (not shown) shown in FIG. 1 for rotating the speaker holder 52, and it is possible to reduce the cost by reducing the parts and to form a simple structure.

  In the second embodiment of the in-vehicle electronic device according to the present invention formed as described above, the arcuate end portions of the sliders 54 and 55 shown in FIG. 10 or FIG. 52 is rotated. Hereinafter, the embodiment using the slider 54 shown in FIG. 10 will be described as a specific example, and will be described in detail with reference to FIG. As shown in FIG. 13, in the second embodiment of the in-vehicle electronic device according to the present invention, first, the operation panel 60 shown in FIG. 13A is removed, and the speaker 2 faces the front surface of the housing 50. By mounting the operation panel 60 on the slider 54 protruding from the front surface of the housing 50 as shown in FIG. 13B from the state, the slider 54 is slid and accommodated in the housing 50, and at the same time the speaker holder 52 rotates in conjunction with each other. More specifically, as shown in FIG. 13C, the slider 54 is automatically driven by a drive source (not shown) in the housing 50 by attaching the operation panel 60 to the slider 54 and pushing it in a little. It is pulled in and begins to store. At the same time, the speaker holder 52 is rotated by being pushed up and pushed up by the arc-shaped end of the slider 54 with which the guide pin 52c abuts, and gradually rotates the speaker 2 in a direction toward the top surface. . When the slider 54 is completely housed in the housing 50, as shown in FIG. 13 (d), the operation panel 60 is drawn to the front surface of the housing 50 and fixed to be overlapped with each other. At the same time, the speaker holder 52 is also rotated so that the directivity of the speaker 2 is set to face the top side of the housing 50.

The guide pin 52c of the speaker holder 52 supported so as to be rotatable inside the housing 50 is arranged so as to be guided. Further, although not shown, the speaker holder 52 is urged by an elastic member such as a spring so that the speaker 2 always faces the front surface in the housing 50. Here, as shown in FIG. 12, the slider 59 is formed with an arcuate guide hole 55a opened on the side surface, and the guide pin 52c of the speaker holder 52 is inserted and guided along the guide hole 55a. Is possible. Therefore, as in the second embodiment shown in FIG. 13, the slider 59 engages with the guide pin 52c and slides back and forth, thereby rotating the speaker holder 52 and setting the directivity of the speaker 2. Can be changed to front or top.

  As described above, according to the third embodiment of the in-vehicle electronic device according to the present invention, as shown in FIGS. 14 and 15, accompanying the operation of the slider 59 that attaches and detaches the operation panel 60 to and from the front surface of the housing 50. Since the speaker holder 52 is rotated, the same effects as those of the second embodiment can be obtained, and a part of the slider 59 that protrudes and appears on the front surface of the casing 50 is formed to be small. It can be formed so as not to damage the front design.
