Abstract
The invention provides a speaker module and a sound-adsorbing material, comprising: a housing and a speaker unit accommodated in the housing, wherein the speaker unit separates a cavity formed by the housing into a front sound cavity and a rear sound cavity; the rear sound cavity is filled with a sound-adsorbing material; and heteroatoms are doped in a crystal structure of the sound-adsorbing material. The application of the above invention can reduce the adsorption of alien molecules by the sound-adsorbing material inside the speaker module, and even reject the alien molecules, thereby ensuring the long-term effectiveness of the sound-adsorbing material and improving the stability of the acoustic performance of the speaker module.
Claims20
A speaker module, comprising a housing and a speaker unit accommodated in the housing, wherein
- the speaker unit separates a cavity formed by the housing into a front sound cavity and a rear sound cavity;
- a sound-adsorbing material is filled in the rear sound cavity;
- and
- a crystal structure of the sound-adsorbing material is doped with heteroatoms.
A sound-adsorbing material, wherein heteroatoms are doped in a crystal structure of the sound-adsorbing material, and the heteroatoms fill a lattice defect of the crystal structure of the sound-adsorbing material, so as to reduce adsorption and combination of alien molecules by the sound-adsorbing material, or
- the heteroatoms partially replace original one or more chemical elements in the sound-adsorbing material to change or cancel the polarity of the sound-adsorbing material.
