Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type embodiment is described in further detail.
Fig. 1 is sound-absorbing assembly axonometric chart of the present utility model, and Fig. 2 is the profile of this utility model sound-absorbing assembly.
As shown in Figure 1-2, for the sound-absorbing assembly 1 of speaker module, including torr shell 11, torr shell 11 is provided with placing trough
113, it is filled with sound-absorbing material 12 in placing trough 113, torr shell 11 is fixed in the rear operatic tunes of speaker module by injection, places
Being provided with voice hole 111 on the bottom land of groove 113, placing trough 113 is internal to be connected with the rear operatic tunes by voice hole 111.Voice hole 111
Constitute the passage of transfer voice so that the sound-absorbing material 12 in placing trough 113 can play sound absorption, improves the sound of speaker
Matter.
The sound-absorbing material 12 placed in placing trough 113 is non-foamed porous particle, such as activated carbon, natural zeolite powder, work
