Abstract

The invention relates to a voice coil, a loudspeaker and a manufacturing method of the voice coil. The voice coil includes a voice coil body made of enameled wire, a starting wire end and an end wire end. The voice coil body is provided with a starting wire outlet position and an end wire outlet position. The end wire end is led out from the exit position of the end line, the exit position of the start line and the exit position of the end line are located at any position in the middle of the voice coil body, and the height of the voice coil body is formed as the height of the voice coil. The invention effectively avoids the problem of an extra layer of wire diameter and height of the voice coil in the existing winding method, reduces the occupation of the vibration space by the winding, and prevents the voice coil from colliding with parts such as the basin frame. The stability and durability of the voice coil are improved, and the acoustic effect is more excellent.

Description

technical field [0001] The invention relates to the technical field of loudspeaker products, and more specifically, to a voice coil, a loudspeaker and a method for making the voice coil. Background technique [0002] A speaker is a device that converts electrical signals into sound signals, and is widely used in electronic devices such as mobile phones and tablet computers. It is mainly composed of magnets, diaphragms, voice coils and other components. The voice coil is the vibration source of the loudspeaker vibration system, which has a very important impact on the sensitivity and frequency response of the loudspeaker. [0003] The voice coil is usually stacked by an enameled wire, and one end is connected to the diaphragm. When the speaker is working, a changing current will pass through the enameled wire of the voice coil. The diaphragm reciprocates, which then pushes the surrounding air to move and emit sound waves. [0004] The existing voice coil is generally wound...
