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： The present disclosure provides a speaker including a frame having an accommodating space, a vibration system and a magnetic circuit system that are accommodated in the accommodating space. The vibration system includes a first diaphragm configured to vibrate and produce sound, a voice coil located below the first diaphragm and configured to drive the first diaphragm to vibrate and produce sound, a flexible circuit board electrically connected to the voice coil and elastically supporting the voice coil, and a second diaphragm fixed to the flexible circuit board. The flexible circuit board includes a first fixing portion connected to the voice coil, a second fixing portion disposed opposite to and separately from the first fixing portion, and an elastic arm connecting the first fixing portion and the second fixing portion. An orthogonal projection of the elastic arm toward the second diaphragm is partially located within a range of the second diaphragm.

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.
