Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a voice coil assembly and a loudspeaker, comprising a main body voice coil and a connecting coil connected with the main body voice coil, the main body voice coil is used for connecting with an external circuit, and the main body voice coil includes a first voice coil and a connecting coil connected with the main body voice coil. The second voice coil, the first voice coil is formed by winding a conductive first wire coated with self-adhesive paint, the second voice coil is formed by winding a second wire coated with self-adhesive paint, and the first voice coil is formed by winding a second wire coated with self-adhesive paint. A voice coil and the second voice coil are closely wound and bonded together, the first voice coil and the second voice coil are connected in series or in parallel, and the connecting coil is formed by winding a third wire, The density of the third wire is less than or equal to the density of the first wire and the second wire, and the first voice coil and the second voice coil can be monitored respectively to model the first voice coil and the second voice coil respectively Analysis allows real-time optimization of the vibration of the voice coil assembly, thereby improving the acoustic performance of the loudspeaker.

Description

technical field [0001] The invention relates to the technical field of acoustic and electric equipment, in particular to a voice coil assembly and a loudspeaker. Background technique [0002] Micro-speakers are widely used in portable electronic devices such as mobile phones, laptops, and hearing aids. With the rapid development of these portable electronic devices, people have higher and higher requirements for the miniature electroacoustic devices used in them. [0003] Among them, the voice coil is an important part of the micro-speaker; in order to obtain a larger amplitude of the speaker, it is necessary to increase the distance from the top of the ball to the washer, but because the voice coil on the side close to the top of the ball is far from the magnetic gap, the BL As the value decreases, the increase in the sensitivity of the voice coil decreases, but in order to ensure the sensitivity of the core and the rigid connection between the voice coil and the diaphragm...
