Embodiment Construction

[0036] 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.

[0037] 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.

[0038] In addition, if there are descriptions involving "first", "second" an...

Abstract

The invention discloses a loudspeaker, and the loudspeaker comprises a shell, a vibration system and a magnetic circuit system. The vibration system comprises a vibrating diaphragm and a voice coil driving the vibrating diaphragm to vibrate. The magnetic circuit system comprises a magnet yoke, a central magnetic circuit structure and a side magnetic circuit structure, wherein a gap is formed between the shell and the side magnetic circuit structure, the loudspeaker further comprises an elastic supporting member which is fixed to the shell and located below the vibrating diaphragm, a conductiveframework is connected between the vibrating diaphragm and the elastic supporting piece, the conductive framework comprises a side wall arranged between the vibrating diaphragm and the elastic supporting member, the side wall is located in the gap, and the conductive framework is provided with a first bonding pad and a second bonding pad; the elastic supporting member comprises a balance diaphragm and a conductive support chip; the first bonding pad is connected with a voice coil wire of the voice coil, and the second bonding pad is connected with an external circuit through the conductive support chip. According to the invention, the conduction between the voice coil and the external circuit is realized through the conductive skeleton and the conductive support chip, the conduction difficulty is reduced, a magnetic circuit system does not need to be broken for avoidance, and the acoustic performance of the product is improved.

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. Due to the above-mentioned structural characteristics of the speaker space, it is difficult to connect the voice coil of the speaker with the external circuit. Contents of the invention [0003] The main purpose ...
