That is, the speaker housing 110 of the speaker assembly itself can enclose the inner cavity for accommodating the vibration unit 120, so that the vibration unit 120 divides the inner cavity into the first cavity 130 and the second cavity 140. The loudspeaker component is convenient to produce and sell independently.
In other possible embodiments, the speaker housing 110 of the speaker assembly comprises a portion of the back plate 20, i.e. the speaker housing 110 portion of the speaker assembly is constructed from a portion of the back plate 20. Or the speaker housing 110 of the speaker assembly includes a portion of the center frame 30, i.e., the speaker housing 110 portion of the speaker assembly is constructed from a portion of the center frame 30. Or the speaker housing 110 of the speaker assembly includes a portion of the back plate 20 and a portion of the center frame 30, i.e., the speaker housing 110 portion of the speaker assembly is constructed from a portion of the back plate 20 and a portion of the center frame 30. The volume of the speaker housing 110 portion of the speaker assembly, which is independent of the center frame 30 and the back plate 20, is reduced, thereby effectively reducing the occupied space of the speaker assembly.
