Embodiment Construction

[0065] 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.

[0066] 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.

[0067] In addition, if there are descriptions involving "first", "second" an...

Abstract

The invention discloses a loudspeaker, which includes a shell, a vibration system, a magnetic circuit system and an elastic support. The vibration system includes a diaphragm and a voice coil for driving the diaphragm to vibrate. The magnetic circuit system includes a yoke and a central magnetic circuit structure and side magnetic circuit structure; the elastic support is connected to the vibration system, and is arranged up and down opposite to the diaphragm to form elastic support for the vibration system; there is a gap between the shell and the side magnetic circuit structure, and the gap between the diaphragm and the elastic support A conductive frame is connected between them, the conductive frame includes a side wall arranged between the diaphragm and the elastic support, the side wall is located in the gap, the conductive frame is provided with a first pad and a second pad, the first pad and the voice coil The voice coil wire is connected, and the second pad is connected to the external circuit. The present invention can realize the conduction between the voice coil and the external circuit through the conductive skeleton, reduces the difficulty of conduction, and does not need to interrupt the magnetic circuit system for avoidance, the volume of the magnetic circuit system is not limited, 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 ...
