Thin speaker with low distortion

Abstract

The invention relates to a thin type speaker with low distortion degree, which comprises a basin frame provided with a basin-shaped cavity, and a magnetic circuit structure, a sound basin and a location support chip which are mounted in the basin frame, wherein the sound basin mainly comprises a sound basin folded ring and a sound basin body. The speaker is characterized in that the edge of the sound basin body extends obliquely and downward towards a center direction of the sound basin body to form a downward-hollowed funnel-shaped curved surface; the funnel-shaped curved surface is bent upward; the edge of the undermost end of the funnel-shaped curved surface extends obliquely and upward towards the center direction of the sound basin body to form an upward-raised dome-shaped curved surface; and a center hole of the sound basin body is formed in the center of the dome-shaped curved surface. According to the speaker, the novel sound basin replaces the traditional funnel-shaped sound basin, and the upward-raised dome-shaped curved surface in the sound basin body can effectively improve medium- and high-frequency sound quality; in addition, an auxiliary magnet and an auxiliary magnetic pole core are additionally arranged in the magnetic circuit structure, so that the low-frequency response characteristic of the speaker can be further improved; the nonlinear distortion can be reduced; and the sound quality performance and the reliability of the speaker can be improved.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a high-power low-distortion thin-type electric loudspeaker, which belongs to the technical field of electroacoustics. Background technique [0002] In the prior art, the loudspeaker applied to the flat-panel video equipment generally adopts the structure of a funnel-shaped sound basin and a positioning support piece. A center hole is opened in the center of the funnel-shaped sound basin, and a positioning support piece with a center hole is also opened. Set under the sound cone, the voice coil runs through the center hole of the sound cone and the positioning support, and the outer wall of the voice coil is closely combined with the inner wall of the center hole of the sound cone and the positioning support, thus forming the vibration system of the speaker. The conventional magnetic circuit structure generally puts the magnet in the center, surrounded by a U-shaped magnetic yoke (also called U-ir...
