Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indications are only used to explain how to move in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second" an...

Abstract

The invention discloses a loudspeaker, which includes a casing, a vibration system and a magnetic circuit system. The vibration system includes a diaphragm and a voice coil for driving the vibration of the diaphragm. There is a gap between the casing and the side magnetic circuit structure of the magnetic circuit system. The loudspeaker also includes a fixed An elastic support located under the casing and below the diaphragm, a conductive skeleton is connected between the diaphragm and the elastic support, the conductive skeleton includes a side wall arranged between the diaphragm and the elastic support, and the side wall is located in the gap; the elastic support The components include a conductive diaphragm and a circuit board. The circuit board is provided with electrically connected internal pads and external pads. The voice coil wire of the voice coil is connected to the conductive diaphragm through the conductive skeleton, and the conductive diaphragm is connected to the internal pad. The external pad conducts with the external circuit. The speaker can realize the conduction between the voice coil and the external circuit by setting a conductive diaphragm and only setting internal pads and external pads on the circuit board. There is no need to set a conductive layer on the circuit board, and there will be no problem of conductive layer breakage. Improve product reliability.

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...
