The space of offer.It should be noted that first connecting portion 240 can be one or more independent components, it can also be with first
Shell 210 is integrally formed.Since first connecting portion 240 is fixedly connected with the first vibration panel 230, in order to reduce the pact to vibration
Beam, which usually has elasticity, such as prepares interconnecting piece using plastic cement (such as polycarbonate).In addition, using
Plastic cement prepares interconnecting piece can also be when vibration panel be driven by transducing head and generates vibration by a relatively large margin, and reduction is transferred to shell
The vibrational energy of body reduces leakage sound to keep the Oscillation Amplitude of shell smaller.
It is understood that the technical solution of the application can be adapted for respectively there are many kinds of the structures of bone-conduction speaker
Kind has the bone-conduction speaker of typical structure.The transducing head of bone-conduction speaker is to realize that electric signal turns based on setting principle
It is changed to the component of mechanical oscillation.For example, transducing head includes magnet and voice coil, audio electrical signal is inputted by sound by electromagnetic action
Circle, voice coil are placed in magnetic field the vibration that can drive voice coil.For another example, transducing head includes piezoelectric ceramics, converts electrical signals to pressure
The variation of the shape of electroceramics and generate vibration.
In order to inhibit above-mentioned leakage sound, the embodiment of the present application increases by the second bone-conduction speaker in wearable device.It is described
Second bone-conduction speaker, for generating the second mechanical oscillation with the phase phase difference predetermined angle of first mechanical oscillation,
Wherein, second mechanical oscillation drive air vibration, form the inhibition sound wave propagated in air, pass through the inhibition sound wave
Interference, which is carried out, with the leakage speech wave realizes inhibition leakage sound.It should be noted that the value range of predetermined angle can be 90 degree
To 270 degree.By taking intelligent glasses as an example, due to being equipped with the first bone-conduction speaker in the left and right sides temple of intelligent glasses, it is
Inhibit leakage sound, the second bone-conduction speaker can be added respectively again in the left and right sides of intelligent glasses, i.e., aforementioned first bone passes

The inner wall side of at least one temple is arranged in bone-conduction speaker 508, bone-conduction speaker 508, for that will receive
To processor 502 send audio signal be converted to vibration signal.Wherein, sound is passed through skull by bone-conduction speaker 508
It is transferred to human body inner ear, is transmitted in skull cochlea by the way that the electric signal of audio is changed into vibration signal, then by auditory nerve
It is perceived.Reduce hardware configuration thickness as sounding device by bone-conduction speaker 508, weight is lighter, while without electromagnetism
Radiation will not be influenced by electromagnetic radiation, and have antinoise, waterproof and liberation ears a little.For example, wearing
Formula equipment includes at least four bone-conduction speaker (also known as oscillator).For example, 4 bone-conduction speakers are set to temple respectively
On, optionally, bone-conduction speaker is located near ear and skin contact region；For example, first bone-conduction speaker setting
In the first position being bonded on left mirror leg with human skin, second bone-conduction speaker is set in the temple of left side and described the
One position is at a distance of the second position of pre-determined distance.Third bone-conduction speaker, which is set to, to be bonded with human skin in right temple
First position, the 4th bone-conduction speaker are set to the second in the temple of right side with the first position at a distance of pre-determined distance
It sets.It should be noted that leakage speech wave and inhibition frequency of sound wave that two bone-conduction speakers being located in same temple issue
And amplitude is identical, phase phase difference 180 degree, realizes that leakage sound is offset after propagating set distance because of interference.
Microphone 509, may be provided on the lower frame of frame, for acquiring external (user, environment) sound and being transmitted to
Processor 502 is handled.Illustratively, the sound that microphone 509 issues user be acquired and pass through processor 502 into
Row Application on Voiceprint Recognition can receive subsequent voice control, specifically, user if being identified as the vocal print of certification user accordingly
Collected voice is sent to processor 502 and identified according to recognition result generation pair by capable of emitting voice, microphone 509
The control instruction answered, such as " booting ", " shutdown ", " promoting display brightness ", " reducing display brightness ", the subsequent basis of processor 502
The control instruction of the generation executes corresponding control processing.
Wearable device provided by the embodiments of the present application may be implemented leakage speech wave and sound wave inhibited to propagate a distance
The amplitude for interfering and weakening leakage speech wave afterwards, can effectively inhibit leakage sound.In addition, transmitted in vibration to auditory nerve
In the process, since the first bone-conduction speaker and the second bone-conduction speaker pass through skin histology and bone to auditory nerve respectively
Sound is transmitted, can build space sound field effect.
Note that above are only the preferred embodiment and institute's application technology principle of the application.It will be appreciated by those skilled in the art that
The application is not limited to specific embodiment described here, be able to carry out for a person skilled in the art it is various it is apparent variation,
The protection scope readjusted and substituted without departing from the application.Therefore, although being carried out by above embodiments to the application
It is described in further detail, but the application is not limited only to above embodiments, in the case where not departing from the application design, also
It may include more other equivalent embodiments, and scope of the present application is determined by the scope of the appended claims.
