Problems solved by technology

The peripheral parts of the traditional positioning support are combined with the steps of the basin frame to prevent the sound cone of the thin speaker from moving laterally under high power conditions, and to prevent the voice coil from touching the magnet or magnetic pole core, resulting in abnormal sound. Positioning the support piece will cause the amplitude of the speaker to vibrate to be too small, the antegrade is not enough, and the low-frequency response will become poor

Abstract

The invention relates to a thin type speaker with wavy positioning support chip. In the speaker, a magnetic circuit structure comprising a U-shaped magnetic yoke and a voice coil is mounted on a cone frame; a cone frame central hole is formed in the center of the cone frame bottom, the U-shaped magnetic yoke is firmly embedded in the cone frame central hole; a positioning support chip is supported on the step arranged on the cone frame, a voice cone is arranged above the positioning support chip and supported on the cone frame; a positioning support chip central hole and a voice cone central hole are respectively opened in the centers of the positioning support chip and the voice cone, and the upper part of the voice coil is mounted in the positioning support chip central hole and the voice cone central hole; and a terminal board is mounted on the lower surface of the step on the cone frame and is connected with an extension line of the voice coil. The speaker is characterized in thatthe positioning support chip is extended from a center to periphery to form a wavy positioning support chip. The invention is intelligently structured, compact and reasonable, is capable of preventing the voice coil from touching a magnetic gap when the speaker is working, limiting transverse movement of the voice cone, improving compliance of the speaker and modifying low-frequency response characteristic.

Description

technical field [0001] The invention belongs to the technical field of acoustics and electricity, and relates to a loudspeaker, in particular to a thin loudspeaker with a wave-shaped positioning support piece. Background technique [0002] In the prior art, the loudspeakers used in LCD, PDP and other flat-panel video equipment generally adopt the structure of conical sound basin and positioning strut (also called centering strut, elastic wave), and a There is a center hole, and the positioning support piece with the same center hole is set under the sound cone. The voice coil passes through the center hole of the sound cone and the positioning support piece, and the center of the sound cone and the positioning support piece are closely combined in the voice coil. On the outer wall, the vibration system of the speaker is formed. The positioning support piece is mainly used to stop the lateral movement of the sound cone in the speaker, to ensure that the sound cone vibrates u...
