Abstract:
The present disclosure discloses a loudspeaker module and relates to the technical field of electroacoustic products. The loudspeaker module comprises an outer casing; the outer casing accommodates a speaker unit; the speaker unit comprises a vibration system and a magnetic circuit system; the speaker unit partitions an inner cavity of the whole module into two cavities: a front acoustic cavity and a rear acoustic cavity; the rear acoustic cavity is internally provided with a sound-absorbing material; the rear acoustic cavity is further provided with an isolating structure used for isolating the sound-absorbing material from the speaker unit; the isolating structure partitions the entire rear acoustic cavity into a filling area and a non-filling area; the sound-absorbing material is located in the filling area; the sound-absorbing material is a foaming material; the sound-absorbing material is formed by the foaming of the foaming material and then fills the filling area. The loudspeaker module of the present disclosure solves technical problems of the loudspeaker module products in the prior art such as undesirable consistency and high production costs. The loudspeaker module according to the present disclosure exhibits a good acoustic performance, a high production efficiency, low production costs and high product consistency.
