Title: SPEAKER MODULE
Abstract:
Disclosed in the present utility model is a speaker module, relating to the technical field of electro-acoustic products. The speaker module comprises: a housing, the housing being accommodated with a speaker unit, the speaker unit dividing the inner cavity of the whole module into two cavities, namely, a front acoustic cavity and a rear acoustic cavity; the housing being provided with a leakage hole at the position corresponding to the rear acoustic cavity; the housing, on the periphery of the leakage hole, being provided with a damper covering the leakage hole, the damper comprising a damping film and an annular acoustic transmission sheet provided in a superimposed manner; and the central hole of the acoustic transmission sheet corresponding to the leakage hole, and the material of the acoustic transmission sheet having a certain rigidity relative to the material of the damper film. The speaker module of the present utility model solves the technical problem in the prior art that the speaker module is of a poor damping bonding quality. The damper of the speaker module of the present utility model will not wrinkle and not tilt up partially, has a good appearance, can maintain a strong bond, and will not easily fall off; in addition, the amplitude symmetry of the vibration system is good.
