A mobile terminal is provided, including a housing () and a speaker (). The speaker () includes a box () and a sound generation unit (). The box () includes a first cover body (), a second cover body (), and a cover plate (). A first chamber is formed between the sounding unit () and the inner bottom wall of the first cover body, and a sound hole () is disposed in the first cavity (). A second cavity () is formed between the sound generation unit () and the second cover body (). The sound generation unit () includes a diaphragm (). A resonant cavity () with a through hole () on one side is formed in the first cover body (), the cover plate () covers the through hole (), and a microhole () is disposed. Airflow enters the second cavity () through the microhole ().

Mobile terminal having housing and speaker

The present invention provides a speaker box, includes a housing having an accommodating space, a speaker unit accommodated in the accommodating space of the housing, and a sound channel formed in the accommodating space. The speaker unit includes a diaphragm that vibrates sound. The diaphragm divides the accommodating space into a front sound cavity and a rear cavity. The sound channel communicates the front sound cavity with an outside and is connected with the front sound cavity to form a front cavity. The sound channel includes a first sound channel communicating the front sound cavity with the outside and two second sound channels communicating with the front sound cavity and the first sound channel. The second sound channels are respectively disposed at opposite sides of the first sound channel.

Speaker box

The present invention provides a speaker box, includes a housing having an accommodating space, a speaker unit accommodated in the accommodating space of the housing, and two sound channels formed in the accommodating space. The speaker unit includes a diaphragm that vibrates for generating sound. The diaphragm divides the accommodating space into a front sound cavity and a rear cavity. The sound channel communicates the front sound cavity with an outside. The sound channel is connected with the front sound cavity to form a front cavity. The sound channel respectively communicates the front sound cavity with the outside. The two sound channels are symmetrically disposed on opposite sides of the speaker unit respectively.

The present invention provides a speaker module, including: a housing; a speaker unit having a frame and a working pad fixed to the frame for electrically connecting the speaker unit to an external circuit; a cover engaging with the frame for forming an accommodating space for receiving the speaker unit. The cover includes a conductive part formed thereon, a conductive pin formed on one side of the cover for electrically connecting with the working pad of the speaker unit, and a conductive terminal formed on the other side of the cover for electrically connecting with the external circuit.

Speaker module

The present application discloses a speaker assembly. The speaker assembly includes a sound generator having a sound radiation surface and a back surface opposite to the sound radiation surface; at least one leakage area formed on the back surface; at least one leakage controller corresponding to the leakage area and covering the leakage area; a damping element disposed on a plane on which the leakage controller is disposed. The damping element is arranged between adjacent two leakage areas. By the configuration, the height of the speaker assembly is reduced.
