[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figures 1 and 2, be electro-acoustic element of the present utility model, it comprises the housing with receiving space and the sounding monomer 10 be contained in housing and vibrating device 30, and described housing, sounding monomer 10 and vibrating device 30 form airtight cavity jointly.
The inner housing 22 that described housing comprises substrate 21, lid connects on the base plate (21 and the shell body 23 that lid is connected on inner housing 22.Described inner housing 22 is provided with through hole 220, and described sounding monomer is contained in described through hole 220.Described receiving space is separated into upper and lower two operatic tunes by described sounding monomer 10 and inner housing 22.Described shell body 23 be provided with run through on it window, described vibrating device is housed in described window.Substrate 21, inner housing 22 and sounding monomer 30 form the lower operatic tunes 42 jointly; Inner housing 22, sounding monomer 30, shell body 23 and vibrating device 30 form the upper operatic tunes 41 jointly.In other execution modes selectable, described electro-acoustic element can also be provided with other operatic tunes.Preferably, in the present embodiment, described substrate 21 is also provided with the step-like support portion 211 for supporting sounding monomer extended to sounding monomer direction from substrate.Like this, sounding monomer can be made fixing more firm, be conducive to the performance improving product.
As shown in Figure 3 and Figure 4, described vibrating device 30 comprises latch plate 303 and the vibrating diaphragm 301 on latch plate 303 that is sticked, and is fixed on vibrating diaphragm 301 for adding the oscillating plate 302 of strong vibration.Described latch plate 303 is fixed on the inwall of described shell body 23, and covers described window 230.Described latch plate 303 comprises the outer shroud 3031 be connected with vibrating diaphragm outward flange, for supporting the inner ring 3032 of described oscillating plate and the linking arm 3033 being connected described inner ring 3032 and outer shroud 3031.Preferably, the inwall of described shell body is also provided with the stage portion 231 for fixing described latch plate 303.In the present embodiment, the edge of described vibrating diaphragm is sticked at the upper surface of described latch plate 303, and namely the edge of described vibrating diaphragm 301 is between latch plate 303 and shell body 23.In other execution modes selectable, described vibrating diaphragm also can be attached at the lower surface of latch plate 303, also can implement.
In the utility model electro-acoustic element, when the vibration sounding of sounding monomer 10, because cavity is airtight, cause chamber air to compress or expand, and the vibrating diaphragm 301 of vibrating device of tending to act vibrates, thus drive vibrating device vibration, thus make electro-acoustic element have better tonequality and bass effect.In actual applications, the quality of vibrating diaphragm material, vibrating device and the effective area of oscillating component can be regulated to obtain suitable acceleration and vibration frequency according to the self performance of application conditions and acoustical generator.
