Problems solved by technology

However, since this kind of speaker has multiple sets of coils wound on one voice coil, the weight of the voice coil is increased by winding multiple sets of coils into one voice coil, and the sensitivity of the speaker will be lost when the voice coil drives the cone.

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention.

[0026] This embodiment provides a multi-input driven speaker. Here, the multi-input refers to having multiple audio signal inputs, and the multiple audio signals are input to multiple voice coils, and the multiple voice coils jointly drive the speaker to produce sound.

[0027] refer to Figure 1 to Figure 4 As shown, the loudspeaker includes a pot frame 1 and a sound cone 2 arranged on the pot frame 1 , and the speaker also includes a main input driving mechanism 3 and a plurality of auxiliary input driving mechanisms 4 . Wherein, the main input drive...

Abstract

The invention discloses a loudspeaker driven by multiple paths of input, which reduces the distortion of the loudspeaker, increases the sensitivity of the loudspeaker, improves the definition of the loudspeaker, and is compact in structure. The loudspeaker comprises a cone frame, a sound cone, a main input driving mechanism and a plurality of auxiliary input driving mechanisms, and the main inputdriving mechanism is arranged among the auxiliary input driving mechanisms; the main input driving mechanism comprises a main voice coil, T iron, a front piece and first magnetic steel, a main voice coil mounting hole is formed in the middle of the voice cone, the upper end of the main voice coil is connected to the main voice coil mounting hole, and a center hole is formed in the middle of the cone frame. Each auxiliary input driving mechanism comprises an auxiliary voice coil and an auxiliary magnetic circuit assembly with an auxiliary magnetic gap. A plurality of auxiliary voice coil mounting holes are correspondingly formed in the voice cone, the upper end of each auxiliary voice coil is connected to the corresponding auxiliary voice coil mounting hole, a plurality of auxiliary magnetic circuit mounting holes are correspondingly formed in the cone frame, and the lower portion of each auxiliary voice coil is inserted into the corresponding auxiliary magnetic gap through the corresponding auxiliary magnetic circuit mounting hole.

Description

technical field [0001] The invention belongs to the field of loudspeakers and relates to a multi-channel input driven loudspeaker. Background technique [0002] Existing speakers generally adopt a cone-shaped sound cone (made of paper, PP and other materials) combined with a positioning support structure. There is a center hole between the cone-shaped sound cone and the positioning support, and the positioning support is arranged under the cone-shaped sound cone. , the single-channel signal input voice coil is passed through the center hole of the positioning support piece and the cone-shaped sound cone, and the cone-shaped sound cone and the positioning support piece are respectively glued to the outer wall of the voice coil to form a speaker vibration system. This kind of speaker can only be used For single signal input, it has limitations on the original sound reproduction. [0003] Therefore, a current improvement method is to use a cone-shaped sound cone combined with ...
