Description
[technical field]
The present invention relates to a kind of transducer, relate in particular to a kind of electroacoustic transducer.
[background technology]
Develop rapidly along with mobile communication cause, user has a more and more higher requirement to mobile phone is light, little, thin, has occurred the loud speaker of three-in-one function thereupon, and receiver, loud speaker, vibration are integrated, to reduce the volume of mobile phone, reach the effect of existing acoustical device.
Electroacoustic transducer related to the present invention comprises acoustical generator monomer and the housing of accommodating described acoustical generator monomer.This kind of electroacoustic transducer only has vocal function, and integrated level is not high, affects the performance of product.
Therefore, be necessary to provide a kind of new electroacoustic transducer.
[summary of the invention]
The object of the invention is to solve the not high deficiency of electroacoustic transducer performance of said structure, and a kind of electroacoustic transducer that can enhance product performance is provided.
The present invention is achieved by the following technical solutions:
A kind of electroacoustic transducer, it comprises the acoustical generator monomer that is provided with the housing of receiving space and is placed in receiving space, described housing comprise upper cover and with the lower cover of upper cover butt, described electroacoustic transducer also comprises the vibrating device that is placed in receiving space, described housing is provided with the through hole that holds vibrating device, and described vibrating device comprises the ring being fixed on housing and the oscillating plate being connected with ring inner surface; The airtight cavity of the common formation of described housing, acoustical generator monomer and vibrating device.
Preferably, on described, be covered with the locating piece to the fixedly acoustical generator monomer extending near lower cover direction from inner surface.
Preferably, on described, be covered with the window that holds acoustical generator monomer.
Preferably, be covered with the through hole that holds vibrating device under described, described ring is fixed on down and covers.
Preferably, under described, be covered with step, described ring and step butt.
Preferably, described cavity comprises the ante-chamber of accommodating acoustical generator monomer and the back cavity of accommodating vibrating device.
Beneficial effect of the present invention is: because housing, acoustical generator monomer and vibrating device form airtight cavity, the vibration of membrane of shaking by acoustical generator monomer causes air compressing and expansion, thereby the vibration of the vibrating device of tending to act, make electroacoustic transducer realize the function of vibration and tactile feedback, make product integrated level high, can be cost-saving; Vibrating device and acoustical generator are installed separately, and vibrating device and acoustical generator are not influenced each other in mechanical structure, thereby improve the performance of product.

Fig. 2 is electroacoustic transducer one embodiment cutaway view of the present invention.
[embodiment]
Below in conjunction with drawings and embodiments, the invention will be further described.
As shown in Figures 1 and 2, for electroacoustic transducer of the present invention, it comprises the housing 10 that consists of upper cover 11 and lower cover 12, is housed in acoustical generator monomer 20 and vibrating device 30 in housing 10, and described housing 10, acoustical generator monomer 20 and vibrating device 30 form airtight cavity (not indicating).Described cavity comprises the ante-chamber (not indicating) of accommodating acoustical generator monomer 20 and the back cavity (not indicating) of accommodating vibrating device 30.
Described upper cover 11 comprises the locating piece 111 of the fixedly acoustical generator monomer 20 that holds the window 110 of acoustical generator monomer 20 and extend to close lower cover 12 directions from upper cover 11 inner surfaces, and described lower cover 12 is provided with the through hole 120 that holds vibrating device 30.Described vibrating device 30 comprises ring 32 and is placed in the oscillating plate 31 on ring 32 inner surfaces, and lower cover 12 is also provided with step 121, and ring 32 is connected on step 121, and described ring 32 is that metal, the various elastomeric materials such as nonmetal form.In other embodiments, also can, at the upper through hole that holds vibrating device that is covered with, vibrating device be fixed on and be covered.
In electroacoustic transducer of the present invention, when the vibrating diaphragm of acoustical generator monomer 20 vibrates, because cavity is airtight, cause air compressing or expansion in chamber, and ring 32 vibrations of tending to act, thereby drive oscillating plate 31 vibrations.In actual applications, can regulate the quality of ring mechanical compliance, vibrating device and the effective area of oscillating component to obtain suitable acceleration and vibration frequency according to the self performance of application conditions and acoustical generator.
Because housing 10, acoustical generator monomer 20 and vibrating device 30 form airtight cavity, the vibration of membrane of shaking by acoustical generator monomer 20 causes air compressing and expansion, thereby the vibration of the vibrating device 30 of tending to act, make electroacoustic transducer realize the function of vibration and tactile feedback, make product integrated level high, can be cost-saving; Vibrating device and acoustical generator are installed separately, and vibrating device and acoustical generator are not influenced each other in mechanical structure, thereby improve the performance of product.
Above-described is only embodiments of the present invention, at this, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make improvement, but these all belongs to protection scope of the present invention.
