Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0017] As shown in the figure, the dual-cone thin speaker in the embodiment is mainly composed of a basin frame 1, a positioning bracket 2, a sub-cone 3, a positioning sheet 4, a main magnet 5, a pole core 6, a sub-magnet 7, a voice coil 8, and a main speaker. Basin 9, dustproof cap 10 and wiring board 11 form.

[0018] Such as Figure 1~Figure 3 As shown, the periphery of the pot frame 1 is the pot frame edge 1a, and the pot frame edge 1a has a recessed pot-shaped cavity inwardly, the bottom of the pot frame 1 is a closed plane, and the terminal board 11 is installed on the pot frame 1, and the pot frame 1 A heat dissipation window 1b is opened on the wall. The basin frame 1 is preferably made of metal or plastic materials that are resistant to high temperature and easy to form.

[0019] Such as Figure 1~Figure 3 As shown, the magnetic circuit structure i...

Abstract

The invention relates to a dual-sound basin thin speaker which comprises a basin frame with a basin-shaped cavity, a magnetic circuit structure arranged in the basin frame, and a main sound basin arranged at the periphery of the magnetic circuit structure, wherein the magnetic circuit structure is closely combined on the inner surface at the bottom of the basin frame; the edge of the main sound basin is supported on the edge of the basin frame, and a central hole wall of the main sound basin is closely combined with an outer wall of a sound coil of the magnetic circuit structure; a wiring board is arranged on the basin frame, and a lead wire of the sound ring of the magnetic circuit structure is connected with the wiring board; a locating support and an auxiliary sound basin are further arranged at the periphery of the magnetic circuit structure; and the bottom of the locating support is closely combined on the inner surface at the bottom of the basin frame, the auxiliary sound basin is positioned below the main sound basin, the edge of the auxiliary sound basin is supported on the top of the locating support, and a central hole wall of the auxiliary sound basin is closely combined with the outer wall of the sound coil of the magnetic circuit structure. The dual-sound basin thin speaker has artful, compact and rational structure, and can ensure compliance of a vibrating system, improve low-frequency response characteristics, rapidly discharge thermal energy and guarantee acoustic performance and reliability of the speaker while optimizing thickness.

Description

technical field [0001] The invention belongs to the technical field of electroacoustics, and relates to a loudspeaker, in particular to a thin loudspeaker with a double-cone structure. Background technique [0002] In the prior art, the loudspeakers used in LCD, PDP and other flat-panel video equipment generally adopt the structure of a funnel-shaped sound basin and a positioning support piece. Surrounding rings are arranged on the edge of the funnel-shaped sound basin, and a ring is opened in the center of the sound basin. Center hole, the positioning support piece with the same center hole is set under the sound cone, the voice coil runs through the center hole of the sound cone and the positioning support piece, 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 piece , thus forming the vibration system of the speaker. In order to further optimize the thickness of the loudspeaker, ...
