Description

Technical Field

[0001] This utility model relates to the technical field of voice coil winding equipment, and specifically to a voice coil winding fixture. Background Technology

[0002] An audio system specifically refers to an audio system composed of electrical equipment that produces sound. A crucial component of an audio system is the speaker enclosure, which typically consists of a speaker unit and a cabinet. The speaker unit is the component that produces sound, while the cabinet complements it, correcting the sound. The principle behind a speaker unit's sound production is the conversion of electrical energy into sound. When different amounts of electron energy are transmitted to the coil, the coil generates energy that interacts with the magnetic field of a magnet. This interaction causes the phonograph to vibrate. Because the electron energy is constantly changing, the speaker coil moves forward or backward, causing the speaker phonograph to move accordingly. These movements change the density of the air, thus producing sound.

[0003] Chinese Patent No. CN218241575U discloses a winding fixture for processing audio coils, including a winding box disposed on the top of an audio coil processing device. The winding box has a top cover, and the top of the top cover has two handles on both sides along its length. A fixing component is disposed on the top of the top cover between the handles to fix coils of different heights. This utility model is applicable to positioning and clamping speaker units during audio coil processing. The top cover is lifted by the handles, and the speaker unit is placed on a rotating disk disposed inside the coil fixing groove. After closing the top cover, the drive cylinder is activated to push the drive rod to move, so that the fixing sleeve is fitted onto the top of the speaker unit, thereby fixing the speaker unit. This winding fixture can be positioned and clamped according to the specifications of different speaker units during use, improving the practicality of the winding fixture.

[0004] However, the above technical solution has the following shortcomings: the installation position of the inlet tube in the existing equipment is fixed, which causes the height of the voice coil wire entering the winding box to remain constant. It cannot be adaptively adjusted according to the change of the winding height of the voice coil wire on the winding roller, which can easily lead to problems such as skipped wires or poor wire layer arrangement, affecting the finished quality of the voice coil.
