Problems solved by technology
[0004] In the prior art, due to the need to leave a certain gap between the vibrating arm of the damper and the housing or the magnetic circuit, the vibrating arm is short, the local stress is too large, and the fatigue resistance is poor, which easily causes the damper to crack or break Case

Embodiment Construction
[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0033] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). Show) the relative positional relationship, movement situation, etc. between the components below, if the specific posture changes, the directional indication will also c...

The invention provides a loudspeaker. The loudspeaker comprises a shell, a magnetic circuit system and a vibration system. The magnetic circuit system is installed on the shell and forms a magnetic gap. The vibration system comprises a voice coil and a centering disk, and the voice coil extends into the magnetic gap; the centering disk comprises a first fixed part, a second fixed part and a vibrating arm; the first fixed part is installed on the shell, the second fixed part is connected with the voice coil, the two ends of the vibrating arm are connected with the first fixed part and the second fixed part respectively, the vibrating arm is connected with the first fixed part through a bent structure, the bent structure comprises a bent section, a first end connected with the first fixed part and a second end connected with the vibrating arm, and the bent structure is fixedly connected with the shell. According to the technical scheme, the length of the vibration arm can be increased, so the local stress of the vibration arm is reduced, the fatigue resistance of the centering disk is improved, and the situation that the centering disk cracks or fractures is avoided.
Description
Technical field [0001] The invention relates to the technical field of electro-acoustic conversion, in particular to a loudspeaker. Background technique [0002] The speaker is an important acoustic component of electronic equipment. It is an energy conversion device that can complete the conversion between electrical signals and sound signals, and is the most basic sounding unit. With the gradual development of miniaturization of electronic devices, the matching speakers have also been developed toward miniaturization, and higher requirements have been placed on the structure and sound quality of the speakers. [0003] During the working process of the micro-speaker, as the working voltage or amplitude increases, the voice coil will gradually become unstable, and it is easy to reach the swing mode during the vibration process. For this reason, the centering support piece is introduced into the loudspeaker. First, the centering support piece is fixedly connected to the housing, an...
