Utility model content
In order to solve the problems of the technologies described above, a kind of Novel movable coil loundspeaker that the utility model provides, its voice coil loudspeaker voice coil adopts four coiling groups, uses interlacing winding mode, significantly reduce effective oscillating mass of voice coil loudspeaker voice coil, also effectively reduce the competitiveness that production cost improves product simultaneously.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of Novel movable coil loundspeaker, comprise magnetic conduction base plate, annular magnet, magnetic conductive splint, frame and voice coil loudspeaker voice coil, with circular conducting magnetic column on described magnetic conduction base plate, described magnetic conductive splint and frame are all provided with through hole and are positioned at center, bonding annular magnet successively on described magnetic conduction base plate, magnetic conductive splint and frame, described frame is bonded with oscillation ring and vibrating basin, this circular conducting magnetic column forms magnetism loop through annular magnet and magnetic conductive splint, and form annular magnetic gap in circular conducting magnetic column surrounding, described voice coil loudspeaker voice coil comprises tubular axis and around the coiling group on tubular axis, this voice coil loudspeaker voice coil includes four coiling groups, often organize interlacing coiling the overlapped lower end around tubular axis forms four winding wire ring layers, voice coil loudspeaker voice coil is placed in annular magnetic gap, and by arranging centring disk, the upper end of voice coil loudspeaker voice coil is fixed on vibrating basin, two terminals of each coiling group protrude upward and are connected respectively by with the binding post be arranged in frame, during from binding post input tone currents, voice coil loudspeaker voice coil is arranged in magnetism loop and produces up-down vibration by magnetic field excitation, vibrating basin and oscillation ring is driven to vibrate thus produce sound.
The improvement of technique scheme, described frame is provided with four binding posts, and each binding post includes two terminals that two lead-in wires are connected respectively coiling group.
The further improvement of technique scheme, described vibrating basin is provided with multiple aperture, and described lead-in wire is connected with voice coil loudspeaker voice coil through aperture.
The further improvement of technique scheme, described vibrating basin is equiped with dust cap.
The beneficial effects of the utility model: the voice coil loudspeaker voice coil of this coil-moving speaker adopts the winding structure of four coiling groups, be different from wire winding in the past, four coiling groups are formed four winding wire ring layers by interlacing winding mode, when four coiling groups are subject to magnetic force by during electric current simultaneously, four coiling groups drive simultaneously and produce vibration, motive force is stronger, response rapidly, therefore its drive efficiency is higher, middle pitch acoustical quality is also better, coiling group adopts the new technology of interlacing coiling that the quality of voice coil loudspeaker voice coil is alleviated, induction reactance reduces, add the length of wire in effective magnetic field, significantly improve the Energy Efficiency Ratio of loud speaker, also effectively reduce the competitiveness that production cost improves product simultaneously.
