A loudspeaker module and an electronic apparatus are disclosed, the loudspeaker module comprises a housing, a loudspeaker unit and a barrier rib body; the loudspeaker unit is provided in an inner cavity of the housing and divides the inner cavity of the housing into a front acoustic cavity and a rear acoustic cavity, the rear acoustic cavity is filled with sound-absorbing particles, and a cavity wall of the rear acoustic cavity is provided with a leakage hole. The barrier rib body is provided in the rear acoustic cavity, at least a part of the barrier rib body faces the leakage hole, and the distance between the leakage hole and the part of the barrier rib body facing the leakage hole is less than the size of the sound-absorbing particles. The technical solution can reduce the occurrence of the situation where the sound-absorbing particles block the leakage hole.

Loudspeaker module and electronic apparatus

A sound generator, which comprises: a housing, a vibration system and a magnetic circuit system. The vibration system and the magnetic circuit system are sequentially accommodated and fixed at a first end of the housing from top to bottom; the magnetic circuit system is provided with a rear sound hole; the housing comprises a first portion corresponding to the vibration system and the magnetic circuit system, and a second portion integrally extending downward from the first portion beyond a bottom surface of the magnetic circuit system; a second end portion of the housing is integrally provided with a housing bottom wall or separately mounted with a lower cover plate; and a rear cavity which is in communication with the rear sound hole is formed between the second portion of the housing, the bottom surface of the magnetic circuit system, and the housing bottom wall or the lower cover plate.

Sound generator

An embodiment of the present invention provides a sound generating device which comprises a housing, wherein a sound generating unit is mounted in the housing, a closed rear cavity is formed between the sound generating unit and the housing, and the sound generating unit is provided with a rear sound hole in communication with the rear cavity, wherein the sound generating unit comprises a magnetic circuit system, an expandable-capacity cavity being provided on the magnetic circuit system, and the expandable-capacity cavity acting as part of the rear cavity to increase a volume of the rear cavity.

Sound generating device

A miniature sounder is mounted in an electronic terminal and comprises a front cover and a housing that are combined together. A vibration system and a magnetic circuit system are accommodated in a space formed by the front cover and the housing in a surrounding manner. Two electrical connection members used for being electrically connected to the vibration system and the electronic terminal is disposed on the housing. An antenna of the electronic terminal is fixedly on the front cover, and the antenna is electrically connected to one of the two electrical connection members, and is electrically connected to a circuit of the electronic terminal by means of the electrical connection members. In the miniature sounder in the present invention, a wireless transceiver function is added to an original sounding function of the miniature sounder, the structure of the electronic terminal is effectively simplified, the design difficulty and the assembly difficulty of the electronic terminal are reduced, the internal space of the electronic terminal is saved, which further promoting the electronic terminal to develop towards a light, thin and compact trend.
