Fig. 2 is the receiving state schematic diagram of the acoustics in one embodiment of the invention.
Embodiment
One embodiment of the invention provides a kind of electric terminal, please refer to Fig. 1, and Fig. 1 is the cross-sectional configuration figure of the electric terminal in the present embodiment.
As shown in Figure 1, this electric terminal has casing, and casing includes a terminal bonnet 101 and display unit 102, has an opening 103 on terminal bonnet 101; Electric terminal also comprises an acoustics 20, and this acoustics 20 comprises Loudspeaker front cover 201; Sound playing unit 202 is arranged on Loudspeaker front cover 201, is used for the audio signal of electric terminal is exported with form of sound; At least one contractable element 203, in this at least one contractable element 203, the first end of each contractable element is connected with Loudspeaker front cover 201; One audio amplifier bonnet 204, in this at least one contractable element 203, the second end of each contractable element is connected with audio amplifier bonnet 204; Wherein, loudspeaker box device 20 can be stretched out terminal bonnet 101 by opening 103 by at least one contractable element 203; Or loudspeaker box device 20 is retracted in casing by opening 103, the shape and size of opening 103 and position are consistent with sound equipment bonnet 204.
Please continue with reference to figure 1, in the present embodiment, sound equipment protecgulum 201 is arranged in the casing of electric terminal, contractable element 203 is passed opening 103 and is connected with sound equipment protecgulum 201, sound equipment protecgulum 201, contractable element 203 and sound equipment bonnet 204 have formed the cavity of a sealing, make the size of the cavity (being volume) of acoustics 20 to change by compression or stretching contractable element 203.
In the present embodiment, contractable element 203 is bellows, and better is double-ply bellows, can increase the wall thickness of acoustics 20, so acoustics 20 can not leaked sound, sensory effects is good.In other embodiments, also can adopt other elements with telescopicing performance as contractable element 203, those skilled in the art can arrange according to actual needs, and the present invention is not restricted.
Below will introduce in detail the use procedure of electric terminal and acoustics 20.suppose that just beginning electric terminal is in off-mode, at this moment acoustics 20 also is in idle state, please refer to Fig. 2, Fig. 2 is the interior schematic diagram of casing that acoustics 20 is accommodated in electric terminal, contractable element 203 is compressed, and sound equipment bonnet 204 covers on opening 103, better, 103 places make some detailed design at opening, snap-in structure for example, make when sound equipment bonnet 204 covers on opening 103, sound equipment bonnet 204 and terminal bonnet 101 form a smooth plane, be that the outer surface of the outer surface of sound equipment bonnet 204 and terminal bonnet 101 is on same plane, the appearance looks elegant of the electric terminal that so can keep, can prevent that also dust from entering electric terminal.
when if at this moment the user wants to use electric terminal, as long as press the starting switch (not shown) of electric terminal, at this moment electric terminal is started working, for example the user wants to play music, so acoustics 20 is also started working, if the music of playing needs a reasonable bass effect, so should increase the volume of acoustics 20, so sound equipment bonnet 204 leaves opening 103, and stretch out, increase the volume (being the state of Fig. 1) of acoustics 20 with this, certainly, if the audio signal of playing does not need good bass effect, at this moment also can select to continue to keep the state of Fig. 2, be that sound equipment bonnet 204 does not stretch out outside terminal bonnet 101.Therefore, can adjust the volume size of acoustics 20 according to the audio signal of playing, to satisfy the demand of multiple different audios.
In addition, because the volume in sound chamber can be regulated, so can coordinate equalizer to mix more tone color, also improve objective indicator simultaneously, can satisfy the industry standard of minimum 160 hertz.
Further, when the starting switch that can be arranged on electric terminal is activated, sound equipment bonnet 204 just stretches out outside terminal bonnet 101, for example can realize by motor, motor is connected between starting switch and sound equipment bonnet 204, when so electric terminal starts, just can automatically sound equipment bonnet 204 be released outside terminal bonnet 101, certainly, the startup of motor can realize by other physical switchs or program command, so the user can increase the volume of acoustics 20 at any time according to actual needs, is user-friendly to.
When the user does not need sound equipment, can manually sound equipment bonnet 204 be rolled back and cover on opening 103, or automatically sound equipment bonnet 204 be got back by motor; Again or when the user closes electric terminal, simultaneously sound equipment bonnet 204 is got back automatically, such as by motor etc.
Further, can be on sound equipment bonnet 204 the mounting distance detecting unit, ultrasound emission and receiving system for example are installed, the phase difference that transmits and receives by contrast, calculate the distance between sound equipment bonnet 204 and barrier, guarantee that sound equipment bonnet 204 encounters barrier stretching out Shi Buhui, can certainly realize by other methods that detects distance, binocular triangle telemetry for example, perhaps infrared degree of depth camera obtains depth information etc., those skilled in the art can arrange according to actual needs, and the present invention is not restricted.
In above each embodiment, electric terminal can be television set, the electric terminal of notebook computer, display or other use acoustics.
One embodiment of the invention adopts the sound equipment bonnet is connected by contractable element with the sound equipment protecgulum, forms a sound chamber that can change volume, so the user can change the volume of sound equipment as required, thereby promotes audiovisual sensation, especially supper bass effect.
Further, also open an opening corresponding with the sound equipment bonnet in one embodiment of the invention on the bonnet of electric terminal, make the sound equipment bonnet stretch out to increase the volume of sound equipment from opening part, and when not needing to increase the sound equipment volume, sound equipment can be accommodated in the casing of electric terminal, so can have the audio visual effect of the ultra-thin and sound equipment of electric terminal concurrently, and make the outward appearance of electric terminal more attractive in appearance.
Further, also install one in one embodiment of the invention apart from detecting unit on the sound equipment bonnet, be used for distance between detection of sound bonnet and a barrier, guarantee that the sound equipment bonnet can not encounter barrier when ejecting.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of claim of the present invention and equivalent technologies thereof, the present invention also is intended to comprise these changes and modification interior.
