Equipped with pickup amplifying circuit, vibratory drive circuit on the audio frequency processing circuit plate, and for eliminating sidetone Anti-side-tone circuit；

The input side connection contact transducing sound pick-up 62 of the pickup amplifying circuit, the outlet side of pickup amplifying circuit connects Reception loud speaker；

The input side connection of the vibratory drive circuit sends microphone, and the outlet side of vibratory drive circuit connects two and shakes Dynamic energy converter 65.

In the utility model first embodiment, multiple basal disc absorption magnets 63 are fixed on the transducing basal disc 61, it is each Basal disc adsorbs the lower end of magnet 63 all higher than the lower disk of transducing basal disc, and transducing basal disc energy elastic deformation is to lower disk and respectively The lower end of a basal disc absorption magnet flushes；The bottom of transducing basal disc 61 offers multiple flutings, is conducive to transducing basal disc and curved wall The fitting of wall.

In the utility model first embodiment, the vibration transducer, contact transducing sound pick-up, pickup amplifying circuit, Vibratory drive circuit, anti-side-tone circuit are the prior art, these circuits and reception loud speaker, transmission microphone, vibration transducing Device, contact transducing sound pick-up connection type be also the prior art.

The operation principle of the utility model first embodiment is as follows：

Two wall sound-conducting apparatus that shake can be separately mounted to the both sides of wall and are allowed to by selection by the wall of magnet adsorption It is facing each other, when the wall sound-conducting apparatus that shakes is installed, the lower disk of transducing basal disc is bonded with wall, the magnetic force of magnet is adsorbed in basal disc Under effect, the lower end that magnet is adsorbed in transducing basal disc compression elastic deformation to lower disk with each basal disc flushes, while contact is changed Energy sound pick-up 62 and two vibration transducers 65 are lifted up under the compressing of wall, and the upper end of two vibration transducers is directly pressed Compel the bottom hole of mesoporous so that the upspringing property deformation of mesoporous hole bottom, to reach lower end and the transducing base of two vibration transducers Two vibration transducers are pressed on wall by the purpose that the lower disk of disk flushes by the transducing basal disc elastic force of itself；Contact When formula transducing sound pick-up is lifted up by wall compressing, escape groove is avoided that contact transducing sound pick-up touches transducing basal disc, And the lower end of contact transducing sound pick-up 62 is less than the lower end of two vibration transducers 65, and the screen resilience of elastic cantilever 67 can incite somebody to action Contact transducing sound pick-up is pressed on wall, and elastic cantilever, which can play the role of avoiding contact with formula transducing sound pick-up, to tremble, and And contact transducing sound pick-up does not have direct Hard link relationship with other components, is avoided that spatial noise is transmitted by rigid structure To contact transducing sound pick-up, signal-to-noise ratio can be improved；In the utility model other embodiments, more vibrations can also be increased Energy converter, to improve vibrational energy.

If two wall sound-conducting apparatus that shake mounted on wall both sides are respectively that the first shake wall sound-conducting apparatus, second wall that shakes is transaudient Device；When work, the first transmission microphone in wall sound-conducting apparatus that shakes picks up the voice of this side user, and user speech is switched to electricity Vibration transducer is passed to by vibratory drive circuit after signal, mechanical oscillation are converted electrical signals to by vibration transducer, are shaken Dynamic wall；The second of the wall other side shakes the mechanical oscillation of the contact transducing microphone pickup wall in wall sound-conducting apparatus, will The mechanical oscillation of wall are played after switching to electric signal by pickup amplifying circuit driving reception loud speaker；Similarly, second shake wall biography It is transaudient by first wall that shakes after the transmission microphone pickup that the user speech of acoustic device side can be shaken by second in wall sound-conducting apparatus Reception loud speaker in device plays；So as to complete the transmission of wall both sides voice signal.

Since transducing basal disc is bonded wall, elastic annular structure energy under the magneticaction that basal disc adsorbs magnet by compression Enough further suppress bad resonance, accelerate vibration convergence, be avoided that appearance vibrate do not restrain caused by vibrate in time folded Add to form reverberation（This reverberation can cause sound ambiguous, can not recognize）.

Since vibration transducer and contact transducing sound pick-up are all mounted on same wall, user says to sending microphone When words, the mechanical oscillation converted by vibration transducer can be by wall by the machine contact transducing microphone pickup, if the signal It is converted into after voice signal to play back by locally received loud speaker and can form sidetone（I.e. user can be raised by locally received Sound device hears the voice of oneself）, therefore anti-side-tone circuit is equipped on audio frequency processing circuit plate, send microphone pickup It after this side user speech switchs to electric signal, in addition to sending to vibration transducer, while sending to anti-side-tone circuit, by contact transducing The machine vibration transducer signal of microphone pickup is eliminated, to avoid the occurrence of sidetone.

The utility model second embodiment and first embodiment difference lies in：It further include wireless communication in second embodiment Terminal, reception loud speaker in second embodiment send microphone and are mounted in wireless communication terminal, receive loud speaker, send Mode is separately connected pickup amplifying circuit, vibratory drive circuit on audio frequency processing circuit plate to microphone by radio communication.

The utility model second embodiment uses wireless solution so that user need not can also speak and receive close to wall It listens, and wireless communication terminal can also be by user's body-worn so that user can move freely in the room.

In the utility model second embodiment, the wireless communication terminal can have it is multiple, in each wireless communication terminal It is fitted with and receives loud speaker, sends microphone；As shown in Fig. 2, 400 both sides of wall between room 401 and room 402 are each One wall sound-conducting apparatus 41,42 that shakes is installed, several wireless communication terminals 411 are set in room 401, are arranged in room 402 Several wireless communication terminals 421, shake wall sound-conducting apparatus 41 and each wireless communication terminal 411 in this room in room 401 Networking is realized by wireless signal, shake wall sound-conducting apparatus 42 and each wireless communication terminal 421 in this room in room 402 Realize that networking, the wireless network in two rooms work, do not interfere with each other independently of one another by wireless signal；Wireless communication terminal 411 The voice for collecting personnel in room 401 is sent to the wall sound-conducting apparatus 41 that shakes by wireless signal, then by the wall sound-conducting apparatus 41 that shakes It is transferred to the wall sound-conducting apparatus 42 that shakes, then is sent to the wireless communication in room 402 by shaking wall sound-conducting apparatus 42 by wireless signal Terminal 421 carries out speech play；Similarly, in room 402 personnel voice, and be transferred in this way in room 401 Wireless terminal 411.
