Abstract: 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.

Abstract: 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.

Abstract: A speaker is disclosed. The speaker includes a magnetic circuit system; a vibration system including a vibrating diaphragm, a voice coil for driving the vibrating diaphragm, and a silicone gel spider elastically supporting the voice coil. The silicone gel spider includes a through-hole passing through an upper surface and a lower surface thereof for balancing air pressure inside and outside of the speaker.

Abstract: A miniature sound generator includes a vibration system including a diaphragm, a voice coil, a damping part supporting the coil elastically, and a fixing system. The voice coil is located below the diaphragm for driving the diaphragm to vibrate and includes a pair of long shaft sides and a pair of short shaft sides. The damping part includes a circuit board arranged on one short shaft side for electrically connecting with the voice coil, and an insulated symmetrical plate arranged on the other short shaft side. The damping part is only arranged at the short shaft sides symmetrically, with one end thereof being fixed with the fixing system, and the other end thereof being fixed with the voice coil. The insulated symmetrical plate has a damping coefficient same to that of the circuit board.
