Abstract
In the present disclosure, a speaker module includes a housing having an accommodating space and a speaker unit accommodated in the accommodating space. The housing includes a bottom wall, a top wall opposite the bottom wall, and a side wall extending from the bottom wall toward the top wall. The speaker module further includes at least one isolating member connected to the top wall and the bottom wall respectively. The isolating member isolates the accommodating space into an accommodating cavity that accommodates the speaker unit and a filling cavity that accommodates a sound-absorbing material. The isolating member includes an isolating frame, a sound-absorbing foam attached to the isolating frame, and a hot melt adhesive layer disposed between the sound-absorbing foam and the isolating frame. The sound-absorbing foam extends beyond an edge of the isolating frame.
