Abstract

The invention discloses a loudspeaker, comprising a casing, a vibration system and a magnetic circuit system. The vibrating system includes a vibrating membrane and a voice coil for driving the vibrating membrane to vibrate. There is a gap between the casing and a side magnetic circuit structure of the magnetic circuit system. The elastic support member and the conductive frame under the diaphragm, the conductive frame includes a side wall arranged between the diaphragm and the elastic support member, the side wall is located in the gap, the conductive frame is provided with a first pad and a second pad, the first The pad is connected with the voice coil wire of the voice coil; the elastic support includes a centering support piece, the centering support piece includes a fixed part fixed to the casing and an elastic part connected with the fixed part, the elastic part is located in the gap and connected with the conductive frame The fixing part is provided with an inner pad and an outer pad which are electrically connected, the inner pad and the second pad are connected by a conductive wire, and the conductive wire extends along the elastic part and is fixed on the elastic part. The centering support piece of the loudspeaker of the present invention will not break during the vibration process, thereby improving the use reliability of the product.

Description

technical field [0001] The invention relates to the technical field of acoustic devices, in particular to a loudspeaker. Background technique [0002] A speaker is a transducer device that converts electrical signals into acoustic signals, and has been widely used in electronic products such as mobile phones, computers, and earphones. A micro speaker usually consists of a vibration system, a magnetic circuit system, and a support system. The vibration system includes an upper vibration system and a lower vibration system. The upper vibration system includes a voice coil and a diaphragm, while the lower vibration system includes elastic supports. The upper and lower vibrating systems are respectively arranged on the upper and lower parts of the product structure. The elastic support includes a damper, which is connected to the voice coil. However, at present, the conductive layer of the damper is prone to breakage during the vibration process, which affects the reliability o...
