Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present invention are only used to explain As shown in the figure), if the relative positional relationship between the various components, etc., if the specific posture changes, the directional indication will also change accordingly.

[0036] It should also be noted that when an element is referred to as being “fixed” or “disposed on” another element, the element may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

Abstract

The invention provides a loudspeaker. The loudspeaker comprises a basin frame, a vibration system and a magnetic circuit system. The basin frame comprises a bottom frame for accommodating the magneticcircuit system and a top cover fixed on the magnetic circuit system. The vibration system comprises a first annular vibrating diaphragm, a second annular vibrating diaphragm, a third annular vibrating diaphragm, an annular spherical top, a voice coil and a framework. The outer side of the first annular vibrating diaphragm is connected with the first side plate. The inner side of the first annularvibrating diaphragm is connected with the outer side of the annular dome. The outer side of the second annular vibrating diaphragm is connected with the second side plate, the framework extends fromthe outer side wall of the voice coil to be connected between the inner side of the annular dome and the inner side of the second annular vibrating diaphragm, the outer side of the third annular vibrating diaphragm is connected with the inner side of the annular dome, and the inner side of the third annular vibrating diaphragm is connected with the top cover. According to the loudspeaker providedby the invention, by arranging the vibration system and adopting a three-diaphragm structure, the vibration of the vibration system can be more balanced, noise generated due to unbalanced vibration iseffectively reduced, and the tone quality is effectively improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of acoustic design, in particular to a loudspeaker. [0003] 【Background technique】 [0004] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common mobile terminal device. At present, mobile phones have various functions, one of which is high-quality music function, and the speaker in the mobile phone is one of the necessary conditions for realizing this high-quality function. [0005] The existing loudspeaker includes a basin frame, a vibration system installed on the basin frame and a magnetic circuit system. The vibration system includes a diaphragm, an annular dome, a skeleton and a voice coil. The annular dome is connected with the diaphragm, and the voice coil is in its vibration direction The skeleton is connected with the ring dome to drive the diaphragm to vibrate and p...
