1 is a perspective view showing a wireless ear set 100 according to an embodiment of the present invention, Figure 3 is a block diagram showing each configuration of a wireless communication control unit 140 of the wireless ear set 100. As shown in FIG. 1, the ear set 100 is an insert type ear set used by inserting and fixing the earphone 110A into a user's auricle.

Referring to FIG. 1, the ear set 100 allows a hands-free kit 110, a wireless communication controller 140, and a hands-free kit 110 and the wireless communication controller 140 to be worn on a user's neck. It is configured to include a collar (150A, 150B, 150C).

The hands-free kit 110 is composed of a microphone 116, an earphone 112A, and a rigid frame 114 connecting the microphone 116 and the earphone 112A.

The microphone 116 converts a user's voice into an electrical signal. The output signal of the microphone 116 is transmitted to the external wireless transceiver (160 in FIG. 3) through the wireless communication controller 140.

The earphone 112A converts a signal of an external communication device received by the wireless communication controller 140 into a voice signal and provides the same to a user. The earphone 112A is further provided with a hook switch 113 for initiating transmission and reception with the external radio transceiver.

The earphone 112A and the microphone 116 are connected by the connection frame 114. The connection frame 114 may be made of a rigid material, for example, metal or plastic material, which maintains a constant shape in the absence of external force. The frame may be rigid enough to maintain a constant distance between the earphone 112A and the microphone 116 connected to the frame. The frame may be formed of a metal material having high rigidity and high ductility. In this case, when the user wears the hands free kit 110, the position of the microphone 116 may be adjusted by bending the metal frame 116. In addition, the frame 116 may be configured to include a member that enables the length adjustment of the frame 116. FIG. 1 shows that the frame 114 is accommodated in a member having an elongated internal receiving space extending from the earphone 112A to enable forward or backward movement in the direction of the arrow. Of course, in addition to the various length adjustment member may be used in the present invention. Adjustable frame 114 of the present invention has several advantages. The first advantage is that the size of the hands free kit 110 can be minimized by retracting the microphone 116 toward the earphones 112A when the ear set 100 is not in use. This minimizes the wearing burden by reducing the volume when the user wears the ear set 100 of the present invention to the neck or when wearing it on the ear. The second advantage is that it is possible to freely move the microphone 116 to a position where the voice of the user is well communicated, thereby ensuring a good transmission state in which the voice of the user is well communicated. In addition, the length-adjustable frame 114 of the present invention has the advantage that the ear set 100 of the present invention can be easily put on and off by adjusting the length of the hands-free kit.

The frame 114 may be provided in the form of a pipe to provide a connection passage of a wire (not shown) for electrically connecting the microphone 116 and the earphone 112A to the wireless communication module.

The wireless communication control unit 140 communicates with an external terminal device 160 of FIG. 3. Referring to FIG. 3, the wireless communication control unit 140 includes a wireless communication module 146 having an antenna 144, a power 143 and a power switch 142 supplied to the wireless communication control unit 140. have. The wireless communication module 146 communicates with the external terminal device 160 through the antenna 144. The antenna 144 may be mounted outside the wireless communication module 146 as shown in FIG. 1, but may be replaced by a wiring pattern on a PCB board on which the wireless communication module is mounted.

The wireless communication controller 140 may wirelessly communicate with the external terminal device 160 in various ways. The communication method may be an infrared transmission / reception technology as well as a radio frequency technology such as Bluetooth technology.

The external terminal device 160 should be provided with an appropriate wireless transmission / reception module 166 that enables wireless communication with the wireless communication control unit 140. The wireless transmission / reception module 166 may be embedded in the external terminal device 160 as shown, or may be provided as a separate module connectable to an input / output terminal of the external terminal device 160. Since many personal communication terminals, that is, mobile phones, PDAs, and computers that are currently being distributed, have a Bluetooth chip, when the wireless communication module 146 of the present invention takes a communication method using Bluetooth technology, a separate wireless transmission / reception is performed on the terminal device. It is not necessary to mount the module.

In addition to the above-described Bluetooth technology, RF schemes in various frequency bands, for example, a short range communication scheme using a 900 MHz frequency band, may be used. This frequency band is consistent with the frequency band used by the communication module of the wired / wireless combined telephone, so there is an advantage in that the communication module mounted in the existing wired / wireless telephone can be used.

When using an infrared transmission and reception module, the wireless communication module includes a light emitting device for converting an electrical signal output from the microphone into an optical signal. In addition, the wireless communication module should include a component such as a photodiode in order to detect infrared rays output from the wireless transmission / reception module 166 attached to the external terminal device 160 and convert them into electrical signals. Since this system transmits and receives in an optical manner, interference of signals can be eliminated, and noise generated in transmission and reception can be reduced.

In the present invention, the external terminal device 160 is not limited to a personal digital communication terminal such as a mobile phone and a PDA and a communication terminal such as a wired telephone. The external terminal device 160 may include all devices capable of inputting and outputting voice signals, such as a computer, an MP3 player, an MD player, a recording and reproducing apparatus, and a CD player. Of course, the external terminal devices may have a built-in or connected wireless communication module 166 of the same method, for example, Bluetooth or RF, capable of communicating with the wireless communication module 146 mounted on the ear set 100 of the present invention. On the premise that In using such an external terminal device 160, if necessary, it is preferable that another earphone 112B is provided in addition to the earphone 112A so that the user can listen to high quality sound.

Referring back to FIG. 1, the hands free kit 110 and the wireless communication controller 140 are connected by the collars 150A, 150B, and 150C. The collars 150A, 150B, 150C are not limited to materials and shapes. For example, the collar may have a string, ribbon, or chain shape, and various materials such as fabric, resin, or metal may be used. However, unlike the connection frame of the hands-free kit 110, the collar is preferably made of a structure or material that can be deformed into various shapes by its own weight. For example, in the case of using a metal material as the collar, it is preferable that the metal ring is applied in the form of a chain connected, the connection form of the hollow metal pipes, or in the form of a metal spring coil.

This not only gives the body a feeling of rejection when the ear set 100 is worn on the neck, but also when the handsfree kit 110 is worn on the ear, the collars 150A and 150B connected to the hands free kit are naturally caused by their own weight. This is because it does not reduce the fit and adhesion of earphones inserted into the user's forearms. In addition, by utilizing various types of materials to increase the functionality as well as aesthetics to have a sufficient effect as an accessory.

Connection between the collar and the hand free kit or earphone may be connected through conventional fastening means. 1 shows a state in which the buckle 152 is used as the fastening means. The buckle 152 facilitates the wearing of the ear set 100.

The collars 150A, 150B, and 150C connect first earphones 150A and 150C connecting the earphones 112A and the wireless communication controller 140, microphones 116, and the wireless communication controller 140, respectively. It may be divided into the second portion 150B. A conductive wire (not shown) for power supply and signal transmission should be connected between the hands-free kit 110 and the wireless communication controller 140. The wire may be connected to the hands free kit 110 and the wireless communication controller 140 along the first or second portion of the collar. To conceal the conductor therein, a fiber-like woven fabric may be used as the collar. Of course, the wire may be attached to the outside of the collar. In addition, when two earphones are used as described above, the electrical connection between the added earphone 112B and the wireless communication controller 140 should be considered.

2 is a perspective view illustrating an insertable wireless ear set according to another embodiment of the present invention.

Unlike FIG. 1, in FIG. 2, relative positions of the earphone 112B and the wireless communication controller 140 are adjusted. The wireless communication control unit 140 is designed to be distributed in close proximity or integrally with the earphone 112B so that the weight of the ear set 100 is appropriately distributed when the user wears it on the ear. In addition, the ear set 100 of FIG. 2 is preferably an aesthetic image because the integrated earphone 112B and the wireless communication controller 140 are in balance with the hands-free kit 110 in appearance.

Hereinafter, with reference to Figure 3, the operation of each component constituting the wireless ear set 100 of the present invention will be described in more detail. Here, it will be assumed that the external terminal device 160 is a mobile phone. When a call signal is received from the other party on the mobile phone 160, the wireless transmit / receive module 166 connected to the mobile phone 160 transmits a call signal to the wireless communication module 146 of the ear set 100 through the antenna 164. Notify that it has been received. The wireless communication module 146 notifies the user that the call signal has been received through the call displaying means 145 in accordance with this notification. The incoming display means 145 may be implemented by a vibration generating device such as a light emitting diode (LED), a speaker or a motor that generates an incoming call sound, or an actuator. Unlike the incoming signal of the mobile phone, the incoming signal generated from the ear set 100 according to the present invention is received by the user even by a small volume or vibration because the ear set 100 is in contact with or very close to the body. It can be easily identified, reducing the risk of incoming sites and reducing power consumption.

When the incoming signal is confirmed, the user may operate the hook switch 113 of the hands free kit 110 to start or end a call. When a call is initiated by the operation of the hook switch 113, the voice of the user or the voice of the other party is transmitted via the wireless communication module 146 of the set 100 and the wireless transmit / receive module 166 of the mobile phone as described above. Are communicated with each other.

As shown, the power source 143 supplies power to the earphones 112A and 112B, the microphone 116, and the call indication means as well as the wireless communication module 144. In the present invention, the power source 143 may be charged by an external adapter. In the present invention, the power switch 142 may turn on / off the power supplied to the wireless communication module 146. By turning off the power switch 142, the user can prevent unnecessary discharge when the ear set 146 is not used.

In the present invention, the hook switch 113 may be used for call transfer to the set 100 even after transmission. That is, when the user selects the desired number and presses the transmission button of the mobile phone to operate the hook switch 113, the call is switched to the ear set 100 of the present invention. In addition, the hook switch 113 may be used when dialing the highest priority telephone number stored in the memory of the mobile phone 160.

In the wireless ear set 100 of the present invention described with reference to FIGS. 1 and 2, the wireless communication control unit 140 is separately installed outside the hands-free kit 110. However, in another alternative embodiment, the hands-free kit 110 of the present invention may incorporate the wireless communication control unit 140. This is made possible by the significant reduction in the size and weight of the wireless chip and the battery according to the development of the wireless transmission and reception technology and the battery manufacturing technology currently in progress. Even in the state of the art, it is not difficult to implement the wireless communication controller 140 in the hands free kit 110 without excessively increasing the size of the hands free kit 110. In addition, the above-described wireless ear set 100 has been described as an insert earphone, for example, the wireless ear set 100 may also be implemented as a stationary earphone. In this case, slight deformation is applied to the shape and structure of the earphones 112A and 112B. For example, the size of the earphone is slightly larger, and the earphone is added with a mounting means that can be inserted into the auricle. In addition, the configuration and function of the remaining components of the ear set 100 are substantially the same as in the above-described insert ear set. In particular, in the case of the stationary ear set, it is very easy to embed the aforementioned wireless communication control unit in the hands-free kit, which will be described later.

4 is a perspective view illustrating a circuit diagram of each component constituting the hands-free kit 210 in the stationary wireless ear set 200 and the stationary wireless ear set according to another embodiment of the present invention. As shown, the wireless ear set 200 is provided with a mounting means 270 that can be mounted on the user's forefinger. Unlike the insertable wireless ear set 100, the stationary wireless ear set 200 has a relatively small limit on the size and weight of the hands-free kit mounted on the user's ear due to the presence of the mounting means 270. Accordingly, it is easy to include a wireless communication control unit 140 installed outside from the insertable hands-free kit 110 in the hands-free kit 210 by making a large portion of the earphone near the insert-type wireless ear set 100. . As shown, the hands free kit 210 includes a power source 243, a power switch 242, earphones 212A, a microphone 230, a hook switch 213, a wireless communication module 246, and an antenna ( 244). Although not shown, the hands free kit 210 may additionally further include an incoming call display means and an adapter for supplying external power to the power source 243. Since the functions and operations of the above components are substantially the same as those of the insertable ear set 100 described with reference to FIGS. 1 to 3, descriptions thereof will be omitted.

In the stationary wireless ear set 200 of the present invention, the collar 250 is bound to the hands free kit 210 in a conventional manner. In such a structure, since all wires are connected in the hands-free kit, there is no need to consider the problem of connecting the conductors to the outside.

The wireless ear set of the present invention is designed so that the wireless ear set naturally forms part of the necklace rather than simply hanging a cell phone or a communication device on the necklace, so that it is easy to wear, carry and operate, and does not give a sense of rejection to the body. The neckline used in the wireless ear set may be made of a light and soft material, so that the wearing feeling and adhesion of the earphone do not decrease even when worn on the ear during a call. In addition, since the call can be initiated by inserting or placing the earphone of the wireless ear set into the ear, it is easy to operate and less disturbed by other tasks such as driving. For example, when using the wireless ear set of the present invention, it is very easy to perform kitchen work while watching a mobile work or traveling with both hands while answering a phone call. This is because no operation is required, such as holding the microphone for the call or connecting or disconnecting the set and the main body. Further, according to the present invention, when the earphone is worn, the microphone is maintained at an appropriate position to transmit the user's voice, so that the user's voice can be effectively transmitted.

By using the present invention in the communication terminal has the following additional advantages.

First, the user can make a call while the mobile phone is attached to the waist dance or stored in a bag, thereby reducing the risk of losing the mobile phone. In addition, since the user can recognize that the call is received without using the loud sound of notifying whether or not the call is received, it can reduce the probability of the user not receiving the call and also enhance mobile phone etiquette in public places. It also helps. In addition, it is possible to reduce the battery consumption of the mobile phone because it is not necessary to use the incoming signal means of the mobile phone, such as a loud volume ringtone or strong vibration to notify the user that the incoming call.

On the other hand, the wireless ear set of the present invention can be indispensable equipment for the application of new technologies emerging with the development of mobile phone-related technologies. In particular, in the case of a camera phone which is attracting attention recently, the mobile phone should be separated from the user in order to capture the user's image, causing inconvenience in voice transmission, and the present invention effectively removes it. In addition, in the case of a wristwatch-type mobile phone developed as a prototype, there is an inconvenience of bringing the wrist close to the ear or the mouth for a call. The ear set of the present invention allows a user to talk in a comfortable posture without using the wrist. Given the increasing trend of mobile devices such as watches, walkmens, MP3 players, mobile phones, PDAs, and notebook computers, the spread of wristwatch-type mobile phones will be greatly expanded. Seems to be. In the past there have been examples of calculators getting into wristwatches, but in this case the technical benefits will be unmatched. Therefore, since the wireless ear set of the present invention can make a call even when the mobile phone is placed at an arbitrary position, it is possible to promote the application of the technology to be commercialized in the future.
