Electronic product body 30 is tightly connected, with the operatic tunes after the restriction between sounding device ontology 10 and electronic product body 30.It is described
The operatic tunes is connected on sealing element 20 and the wall surface of electronic product body 30 from second side of vibrating diaphragm afterwards.The sealing element 20 is matched
It is set to the volume of the operatic tunes after capable of changing.
To volume, thickness of product facility entirety etc., higher requirements are also raised for the fast development of electronic product, this is just
Need the reduced space configured in product facility by each component.Sounding device is the biggish portion that takes up space in electronic product
Part usually requires that sounding device has the operatic tunes after biggish sealing to guarantee that sounding device has preferable acoustical behavior.This
The sounding device that embodiment provides is applied in electronic product body, is limited in the accommodating cavity of electronic product body by sealing element
Make the rear operatic tunes.Utilize the characteristic of sealing member material and structure, thus it is possible to vary the volume of the rear operatic tunes corresponding to sounding device.Into
And the requirement in the case of meeting different application to the acoustical behavior of sounding device.
