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 the mobile communication cause, the user is light, little to mobile phone, thin more and more higher requirement, the loud speaker of three-in-one function occurred 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 electroacoustic transducer only has vocal function, and integrated level is not high, influences 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, the acoustical generator monomer that it comprises the housing that is provided with receiving space and places receiving space, described housing comprise loam cake and with the lower cover of loam cake butt, described electroacoustic transducer also comprises the vibrating device that places receiving space, described housing is provided with the through hole that holds vibrating device, and described vibrating device comprises ring that is fixed on the housing and the oscillating plate that is connected with the ring inner surface; The airtight cavity of the common formation of described housing, acoustical generator monomer and vibrating device.
Preferably, be covered with on described from the locating piece of inner surface to the fixedly acoustical generator monomer that extends near the lower cover direction.
Preferably, be covered with the window that holds the acoustical generator monomer on described.
Preferably, describedly down be covered with the through hole that holds vibrating device, described ring is fixed on down and covers.
Preferably, be covered with step, described ring and step butt under described.
Preferably, described cavity comprises ante-chamber of accommodating the 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 constitute airtight cavity, the vibration of the vibrating diaphragm by the acoustical generator monomer causes air compression 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 height, can save cost; Vibrating device and acoustical generator are installed separately, and make vibrating device and acoustical generator not influence each other on mechanical structure, thereby improve the performance of product.

Fig. 2 is electroacoustic transducer one an embodiment cutaway view of the present invention.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As shown in Figures 1 and 2, be electroacoustic transducer of the present invention, it comprises the housing 10 that is made of loam cake 11 and lower cover 12, is housed in acoustical generator monomer 20 and vibrating device 30 in the housing 10, and described housing 10, acoustical generator monomer 20 and vibrating device 30 constitute airtight cavity (indicating).Described cavity comprises ante-chamber (not indicating) of accommodating acoustical generator monomer 20 and the back cavity (not indicating) of accommodating vibrating device 30.
Described loam cake 11 comprises the window 110 that holds acoustical generator monomer 20 and from the locating piece 111 of loam cake 11 inner surfaces to the fixedly acoustical generator monomer 20 that extends near lower cover 12 directions, described lower cover 12 is provided with the through hole 120 that holds vibrating device 30.Described vibrating device 30 comprises ring 32 and places oscillating plate 31 on ring 32 inner surfaces, and lower cover 12 also is provided with step 121, and ring 32 is connected on the step 121, and described ring 32 is that metal, various elastomeric materials such as nonmetal are formed.In other embodiments, also can be at the last through hole that holds vibrating device that is covered with, vibrating device is fixed on covers.
In electroacoustic transducer of the present invention, when the vibrating diaphragm of acoustical generator monomer 20 vibrates,, cause air compression or expansion in the chamber because cavity is airtight, 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 obtains 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 constitute airtight cavity, the vibration of the vibrating diaphragm by acoustical generator monomer 20 causes air compression 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 height, can save cost; Vibrating device and acoustical generator are installed separately, and make vibrating device and acoustical generator not influence each other on mechanical structure, thereby improve the performance of product.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
