Abstract

The invention provides a sounding device, a voice coil thereof and a winding method of the voice coil. The voice coil is provided with a through hole, and the voice coil comprises a first voice coil and a second voice coil fixedly connected with the first voice coil. The second voice coil comprises an inner layer which is connected with the first voice coil and forms a through hole with the firstvoice coil, and an outer layer which is formed at one side, far away from the through hole, of the inner layer. The outer layer is provided with a protruding part protruding out of the inner layer inthe axis direction of the through hole; the surface of the side, away from the through hole, of the first voice coil is coated with the protruding part; the protruding part is connected with the firstvoice coil; and the number of single-layer turns of the outer layer is equal to the sum of the number of single-layer turns of the inner layer and the number of single-layer turns of the first voicecoil. Compared with the prior art, the sounding device, the voice coil thereof and the winding method of the voice coil reduce the influence of the first voice coil on the second voice coil, thereby achieving the purpose of arranging the voice coil so as to improve the performance of the voice coil.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a sounding device, a voice coil thereof, and a winding method for the voice coil. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. Sound-generating devices for playing sound are widely used in smart mobile devices such as mobile phones. Among them, sound-generating devices with a double-layer voice coil structure are widely used in mobile devices due to their high-quality acoustic performance. [0003] The sound-generating device in the related art includes a pot frame, a vibrating system respectively fixed on the pot frame and a magnetic circuit system with a magnetic gap. A voice coil that emits sound through membrane vibration, and the voice coil includes a first voice coil ...
