Embodiment Construction

[0024] 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 some 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.

[0025] 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 the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a loudspeaker including a housing, wherein the vibration system and the magnetic circuit system are accommodated in the shell; the vibration system comprises a vibrating diaphragm group and a voice coil group for driving the vibrating diaphragm group to vibrate. The vibrating diaphragm group comprises a main vibrating diaphragm and an auxiliary vibrating diaphragm, the voice coil group comprises a first voice coil and a second voice coil, the first voice coil is arranged between the main vibrating diaphragm and the auxiliary vibrating diaphragm, and the second voice coil is arranged on one side, away from the main vibrating diaphragm, of the auxiliary vibrating diaphragm. The loudspeaker comprises a first voice coil and a second voice coil, equivalently, the singlevoice coil structure is disassembled into a double voice coil structure, the auxiliary diaphragm is not arranged at the lower end of the second voice coil any more, and the auxiliary diaphragm is arranged between the first voice coil and the second voice coil, so that the mounting position of the auxiliary diaphragm is raised, the vibration space of the auxiliary diaphragm is increased, and the requirement of large-amplitude vibration of the auxiliary diaphragm is met.

Description

technical field [0001] The invention relates to the technical field of acoustic devices, in particular to a loudspeaker. Background technique [0002] With the development of mobile phone technology, higher requirements are placed on the speaker, the product is getting thinner, the amplitude is getting bigger, and the vibration space is getting smaller and smaller. When the product amplitude is large, the polarization problem of the vibration system will be aggravated. At present, the industry uses a dual-diaphragm system with a main diaphragm and an auxiliary diaphragm to suppress polarization. However, the traditional dual-diaphragm system generally adopts a single voice coil structure. The diaphragm is attached to the upper end of the voice coil, and the auxiliary diaphragm is attached to the lower end of the voice coil. Due to the high height of the single voice coil, the auxiliary diaphragm is limited by the space, and the height of the auxiliary diaphragm is small, so ...
