A voice coil introduction fixture

Abstract

The invention discloses a clamp for importing a voice coil. The clamp comprises a clamp machine body, the clamping machine body comprises a clamp support plate, and a fixed box is fixedly mounted in the middle of the upper surface of the clamp support plate; an electromagnet is fixedly mounted in the fixed box, a sleeve is connected with the outer surface of a threaded column through an outer screw thread in a matched mode, and a limit circle is fixedly arranged at the upper end of the outer surface of the sleeve in a sleeving mode; six sets of limit grooves are evenly formed in the outer sidesurface of the limit circle, and vertical rods are movably mounted in the six sets of the limit grooves through shaft rods. According to the clamp for importing the voice coil, the sleeve which accords with the inner diameters of the voice coils of different sizes is screwed on the outer surface of the threaded column so that the sleeve can be inserted into the voice coil, then the electromagnetis powered-on so that the electromagnet can generate magnetism, accordingly the sleeve has magnetism and is attached to the outer wall of the voice coil through multiple sets of the vertical rods, thefunction of clamping the voice coil is achieved, the efficiency of voice coil assembling is improved, and through rubber gaskets, the voice coil can be prevented from being damaged by the vertical rods.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a voice coil introducing fixture. Background technique [0002] The direct definition of the voice coil is the coil through which the audio current passes. It is an important part of the vibration system of the electrodynamic speaker, and it can also be said to be the heart of the speaker. The performance of the voice coil will affect the sound pressure frequency characteristics of the speaker, sound pressure level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, etc., especially related to the power and life of the speaker. Just like the fatal factor of heart disease, the damage of the speaker often starts from the voice coil, so the quality of the voice coil is very important. Now in the production and assembly process of the voice coil, the material trays are often arranged in order The method of clamping the voice coil is in...

Problems solved by technology

Just like the fatal factor of heart disease, the damage of the speaker often starts from the voice coil, so the quality of the voice coil is very important. Now in the production and assembly process of the voice coil, the material trays are often arranged in order The method of clamping the voice coil is inefficient and easy to damage the voice coil. Therefore, we propose a voice coil importing jig to solve the above problems
