摘要： The present disclosure provides a speaker, including a housing and a vibration unit and a magnetic circuit unit that are received in the housing. The magnetic circuit unit includes a magnetic frame, the magnetic frame comprising a bottom wall and a sidewall extending from the bottom wall while being bent towards the housing. A positioning portion protruding outwardly is provided on the sidewall of the magnetic frame, and the positioning portion abuts against the housing. The speaker of the present disclosure can achieve the positioning of the magnetic frame using the positioning portion provided on the sidewall of the magnetic frame during the assembling, and it is unnecessary to sacrifice the flanging length of the magnetic frame, so that the flanging of the magnetic frame can be maximized, thereby improving the performance of the speaker.

摘要： A speaker, having a firmer structure, includes a metal holder, a magnetic circuit unit including a first diaphragm, and a vibration unit including a clamp plate. The clamp plate includes long-axis edges and short-axis edges. The holder includes long edges, short edges, and corner portions. The short edge includes a first surface facing away from the first diaphragm. The short-axis edge abuts against the first surface. The short-axis edge includes a second surface facing the short edge. The corner portion includes a third surface facing away from the first diaphragm. The holder further includes a protrusion extending from the first surface in a direction facing away from the first diaphragm. The clamp plate further includes an avoiding portion formed by recessing from the second surface in a direction facing away from the short edge. The protrusion is received in and connected to the avoiding portion.

摘要： The present invention provides a sound generator including: a frame, a magnetic circuit system with a magnetic gap, and a vibration system fixed at the frame. The vibration system includes a vibrating diaphragm fixed at the frame, a voice coil inserted in the magnetic gap for driving the vibrating diaphragm to vibrate, and an elastic support assembly fixed at the frame and opposite to but spaced from the vibrating diaphragm, the elastic support assembly being fixed at one end of the voice coil far away from the vibrating diaphragm. The elastic support assembly includes an elastic part having a first fixation arm fixed at the frame, a second fixation arm fixed, and an elastic arm connecting the first fixation arm to the second fixation arm, and a bending unit obliquely extending from the elastic arm protruding towards a direction toward the vibrating diaphragm.

摘要： The present invention discloses a speaker, including a holder, a vibration unit and a magnetic circuit unit that are fixed to the holder. The magnetic circuit unit includes a yoke fixed to the holder, a main magnet and an auxiliary magnet that are assembled on the yoke. The main magnet is spaced apart from the auxiliary magnet to form a first magnetic gap. The yoke includes a bottom wall and a sidewall formed by extending from a periphery of the bottom wall while being bent. The main magnet and the auxiliary magnet are assembled on the bottom wall. The auxiliary magnet is provided along a long axis direction of the bottom wall. The sidewall is located in a short axis direction of the bottom wall, and the sidewall is spaced apart from the main magnet to form a second magnetic gap.

摘要： The present disclosure provides a speaker including a holder, a vibration unit and a magnetic circuit unit that are received in the holder. The vibration unit includes a voice coil, a flexible circuit board, and a diaphragm. The flexible circuit board includes a body portion and a pad portion extending inwardly from the body portion. The pad portion is electrically connected to the voice coil, and the magnetic circuit unit is provided with an avoiding portion for receiving the pad portion at a position corresponding to the pad portion. In the speaker according to the present disclosure, a local position of the flexible circuit board is connected to the voice coil, so that the magnetic gap will not be sacrificed, thereby improving the acoustic performance of the speaker and improving user experience.

摘要： The invention discloses a sound device. The sound device includes a frame and a lower plate. The frame includes a side wall and a leaking hole penetrating the side wall. The sound device also includes an air-permeable isolator covering the leaking hole, and the air-permeable isolator covers the leaking hole completely. Compared with the related technologies, when the sound device is provided in the box body to form a sound device box, a back cavity circumvented and formed by the sound device and the sound device box can be directly filled with acoustic absorbent to form a virtual acoustic cavity.
