Abstract
The utility model relates to a double cone loudspeaker, including the basin frame, the cone, play the ripples, the voice coil loudspeaker voice coil, the magnetic conduction upper plate, with the magnet steel, the magnetic conduction hypoplastron, the sealing washer, the iron core, aluminium ring and support, on same central line, magnetic conduction upper plate and the riveting of basin frame, the upper plate, the magnet steel, the magnetic conduction hypoplastron bonds together in proper order, the iron core, aluminium ring, the support bonds in proper order and inserted the sealing washer centre bore and made the iron core insert at combination upper plate well, in the magnetic conduction hypoplastron centre bore, and messenger's magnetic conduction hypoplastron, the sealing washer, the support bonds together in proper order, and the voice coil loudspeaker voice coil closes the back cover on the iron core with the bullet composite wave, to play the ripples bonds with the basin frame, cone lower extreme borehole jack bonds outside the voice coil loudspeaker voice coil, the up end bonds with the basin frame, the voice coil loudspeaker voice coil is two independent windings separately, according to use occasion and condition, can adopt parallelly connected, establish ties or the mode of connection such as recommend and be connected the use with the power amplifier, technological effect is that the speaker number has increased the one time, improved sensitivity 3dB and speaker power, reduced the degree of distortion, connect in addition use very convenient.
Description
Technical field
The utility model relates to a kind of loud speaker, particularly a kind of double-coil loudspeaker.
Background technology
With regard to woofer, have from 5 " to 8 " various bore, the degree of depth that the bore of bass unit often determines bass dive is felt with amount, certainly speaker port footpath is the bigger the better naturally, because the cone that area is larger can promote the air of more volume, bring the lifting of amount of bass sense, be therefore more good at the torrential imposing manner of performance and powerful impact.Nowadays, the development and apply of the technology such as the up-to-date sound effect technology of Doby newly-increased on circuit, the new research topic that constantly allowed electroacoustic industry have, meanwhile, how reducing volume and to improve bass effect, has been the needs of society.
Summary of the invention
In view of the demand of existing market, the utility model provides a kind of double-coil loudspeaker, make full use of the tow sides of one piece of magnet, two loud speakers have been made with one piece of magnet, number of loudspeakers is made to add one times, improve sensitivity 3dB, the power of loud speaker have also been obtained corresponding raising, concrete technical scheme is, a kind of double-coil loudspeaker, comprise frame, cone, play ripple, voice coil loudspeaker voice coil, magnetic conduction upper plate, by magnet steel, magnetic conduction lower plate, sealing ring, iron core, aluminium ring and support, it is characterized in that: on same center line, magnetic conduction upper plate and frame are riveted, upper plate, magnet steel, magnetic conduction lower plate bonds together successively, iron core, aluminium ring, support is bonding is successively inserted through sealing ring centre bore and upper plate iron core being inserted in combine, in magnetic conduction lower plate centre bore, and make magnetic conduction lower plate, sealing ring, support bonds together successively after voice coil loudspeaker voice coil combines with bullet ripple and is enclosed within iron core, ripple will be played bonding with frame, cone lower end borehole jack is outer and bonding at voice coil loudspeaker voice coil, upper surface is bonding with frame, described voice coil loudspeaker voice coil is two separately independently windings, according to the occasion used and condition, can adopt parallel connection, connects or the mode of connection such as recommend to be connected with power amplifier and to use.Technique effect of the present utility model is that number of loudspeakers adds one times, improves sensitivity 3dB, reduces the distortion factor, improve the power of loud speaker, and it is very convenient to connect use.
Accompanying drawing explanation
Fig. 1 is section of structure of the present utility model.
