Description
Technical Field
The invention relates to the field of loudspeaker production, in particular to a magnetic core pasting machine for loudspeaker production.
Background
The loudspeaker is a modern electroacoustic component, which is used for converting an electric signal into sound, and is also called a loudspeaker, which is a conversion device for converting electric energy into sound, when different electronic energy is transmitted to a coil, the coil generates energy to interact with a magnetic field of a magnet, the interaction causes the vibration of a paper disc, because the electronic energy is changed at any time, the coil of the loudspeaker can move forwards or backwards, so the paper disc of the loudspeaker can move along with the coil, the action causes the density degree of air to change to generate sound, a magnetic core is required to be arranged on the paper disc in the production process of the loudspeaker, because alternating current flows through a voice coil of the loudspeaker, an alternating magnetic field can be generated, the magnetic field is in a fixed magnetic field, two magnetic fields can generate two different actions of like pole attraction and opposite pole repulsion, and the voice coil can generate two different motions of attraction and repulsion, the cone connected with the voice coil pushes air to move back and forth to generate air vibration motion with the same law as that of alternating current, if a non-magnetic iron core is not fixed in the voice coil, no matter whether the alternating current is positive half-wave or negative half-wave, the motion of the magnetic field of the voice coil and the iron core is attraction, no pushing action is performed, the alternating current motion is changed into pulse motion, the generated sound is distorted, the general magnetic core mounting mode is that a strong adhesive is used for being stuck in a paper disc, the magnetic core is fixed through the strong adhesion of the strong adhesive, the flow is mostly operated manually, the magnetic core can be accurately stuck manually, but the manual operation consumes a large amount of time and cannot be quickly stuck on a large scale, the working efficiency is obviously reduced, the stuck magnetic core can be continuously processed after long-time waiting for the complete solidification of the strong adhesive, and the production efficiency is influenced, therefore, the magnetic core pasting machine for loudspeaker production is needed, the pasting of the paper cone and the magnetic core can be automatically completed in batches by the magnetic core pasting machine, the precision is high, and the efficiency is high.
