Loudspeaker

Abstract

The invention discloses a loudspeaker. The loudspeaker comprises a fixing system and a vibration system, the fixing system comprises a basin frame, a lower clamp board which forms an accommodating space with the basin frame, main magnetic steel which is arranged in the accommodating space and is arranged on the lower clamp board, auxiliary magnetic steel which forms magnetic gaps with the main magnetic steel, and an upper clamp board which is arranged on the auxiliary magnetic steel and fixed with the basin frame. The upper clamp board fixes the auxiliary magnetic steel in the accommodating space. The upper clamp board comprises a body corresponding to the auxiliary magnetic steel in shape, and multiple bending parts extending from the body toward the lower clamp board. The outer sides of the auxiliary magnetic steel recess to form avoidance parts corresponding to the bending parts, and the bending parts pass through the avoidance parts. In the speaker provided by the present invention, the auxiliary magnetic steel is sandwiched between the body and the lower clamp board, and is positioned by the bending parts, so that the magnetic circuit structure can be effectively protected when the product falls.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a loudspeaker. 【Background technique】 [0002] With the rapid development of science and technology, the popularity of audio equipment is getting higher and higher. People's requirements for audio equipment are not limited to video and audio playback, but also require more requirements for the reliability of audio equipment.
