The present disclosure discloses a speaker module including a housing and a speaker unit received in the housing, comprising: a frame, a magnet system, including: a yoke fixed to the frame; and a first magnet fixed to the yoke; a vibration system mounted on the frame, including: a diaphragm fixed to the frame; and a coil fixed to the diaphragm and inserted into the magnetic gap; a connector surrounding the yoke and configured to connect the yoke with frame; wherein the housing includes an upper cover enclosing a front cavity with the diaphragm, a bottom cover fixed to the yoke, and a side wall enclosing the receiving space with the upper cover and the bottom cover; a surface of the yoke away from the first magnet is fixed to the bottom cover; the speaker module in the present disclosure has high sealability.

Speaker module

A coaxial speaker is disclosed. The coaxial speaker includes two sounding units and a magnetic circuit system including a lower plate, two first magnets arranged on the lower plate and spaced along a long axis, a first yoke arranged on the two first magnets, and a second magnet and two third magnets arranged on the first yoke and between the two first magnets. The two third magnets are arranged on both sides of the second magnet along a short axis. The lower plate has a through hole arranged between the two first magnets and extends two side walls along the long axis. The two side walls together with the two first magnets and the two third magnets form a first gap. The second magnet and the two third magnets form a second gap. The coaxial speaker reduces the product height and has a compact overall structure.

Coaxial speaker

The present disclosure discloses a sound device including a frame, a magnet system, and a first vibration system and a second vibration system. The magnet system includes a first inner yoke, a main magnet fixed to the first inner yoke, and a second inner yoke fixed to one side of the main magnet away from the first inner yoke; the first vibration system includes a first diaphragm, a first coil surrounding the second inner yoke, and a first FPC electrically connected with the first coil; the first coil includes a first corner portion; the first FPC includes a first fixation portion, a first welding portion welded to the first coil, and a first elastic portion; the first welding portion is located on one side of the first corner portion away from the second inner yoke. The sound device has better magnetic field performance and vibration performance.

Sound device

The present disclosure provides a loudspeaker, which includes a frame, a first diaphragm supported on the frame, a first voice coil that drives the first diaphragm to vibrate and sound, a magnetic circuit system with a first magnetic gap, and a first circuit board set between the first diaphragm and the first voice coil. Compared with the related technology, the loudspeaker of the present disclosure guarantees the reliability of the bonding of the first circuit board, the first voice coil and the first diaphragm.

Loudspeaker

The present disclosure discloses a sound device including a frame, a magnet system, a first vibration system and a second vibration system. The magnet system includes a first inner yoke, a main magnet, a side magnet, a first side yoke, and a connection portion. A first coil of the first vibration system is inserted in to a first magnetic gap. A first FPC of the first vibration system includes a first fixation portion, a first welding portion welded to the first coil, and a first elastic portion connecting the first fixation portion with the first welding portion; the first elastic portion is spaced apart from the first side yoke along a vibration direction; the first welding portion is fixed to a side of the first side yoke facing the first diaphragm. The sound device has better magnetic field performance and vibration performance.
