Voice coil, loudspeaker and manufacturing method of voice coil

Abstract

The invention relates to a voice coil, a loudspeaker and a manufacturing method of the voice coil. The voice coil comprises a voice coil body formed by winding an enameled wire, a starting wire end and a tail wire end,wherein the voice coil body is provided with a starting wireoutgoing position and a tail wireoutgoing position, the starting wireend is led out from the starting wireoutgoing position, the tail wireend is led out from the tail wireoutgoing position, the starting wireoutgoing position and the tail wireoutgoing position are located at any position in the middle of the voice coil body, and the height of the voice coil body is formed to be the height of the voice coil. The problem that in an existing winding mode, the height of one more layer of wire diameter of the voice coil isincreased due to the fact that wires are led out from two ends of the starting wire is effectively solved, the occupied vibration space of winding is reduced, collision between the voice coil and parts such as a basin stand is prevented, 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...
