Abstract
The utility model relates to a loudspeaker which is designed for converting multiple bases voice control into single base voice control. The loudspeaker comprises a bottom magnetic base which is composed of a lower yoke base and a magnetic coil, a voice coil, a cylindrical body film sheet, a concave chamber in the center of the voice coil of the bottom magnetic base, a magnet block arranged in the concave chamber, the other voice coil and film sheet driven under control, a cover sheet for shielding and a capacitor for voice partition; the voice coil and the cylindrical body film sheet can drive pronunciation; the other voice coil and the film sheet driven under control are assembled in a gap at the point between the peripheral walls of the magnet block and in the concave chamber. The utility model sends out desired low, middle and treble voices via a single base body, having the advantages of simple structure, low cost and flat surface.
Description
The utility model relates to a kind of loud speaker, relates to a kind of loudspeaker monomer formula control sound mechanism or rather.
Existing loud speaker is a power type mostly, is mainly driven with rated current, and its control sound mechanism comprises yoke base, magnetosphere, voice coil loudspeaker voice coil, magnetic coil and cylindrical shell diaphragm down.When loud speaker is switched on, because of ordering about voice coil loudspeaker voice coil formation, magneticaction pumps, cooperate the cylindrical shell diaphragm that sound is amplified output, because the sound press value that following yoke base magnetosphere can send is certain, thereby, alt control sound mechanism also will be formed and be sent with magnetosphere seat separately, because the essential array magnetosphere seat that uses, make complex structure, cost improves, and the middle and high sound magnetic support of articulatory configuration need be arranged on the suitable height place of loud speaker, thereby cause the loud speaker surface elevation, influence it and fix and install.
The purpose of this utility model is to improve the multiple seat type loadspeaker structure, designs a kind of loud speaker single seat (body) formula control sound mechanism with simpler structure, saves the middle and high sound generation device of existing loud speaker, and can form smooth loud speaker surface.
The utility model comprises by magnetosphere seat at the bottom of the following yoke that descends yoke base and magnetosphere to form and the voice coil loudspeaker voice coil and the cylindrical shell diaphragm that can be driven sounding, its structure-improved is: at the default alcove of end magnetosphere seat central authorities upper surface, in alcove, insert another magnet and another group and can be driven voice coil loudspeaker voice coil, the diaphragm of sounding, the outside electric capacity control partial that also connects of loud speaker.
Describe technology of the present utility model in detail below in conjunction with the embodiment accompanying drawing:
Accompanying drawing 1 is the contour structures schematic diagram of loud speaker in the prior art.
Accompanying drawing 2 is the structural representation of improved structure of loudspeaker.
Accompanying drawing 3 is the contour structures schematic diagram of improved structure of loudspeaker.
Referring to accompanying drawing 1,10 are following yoke base among the figure, and this time yoke base is provided with magnetosphere 11, and there is voice coil loudspeaker voice coil 12 inside loudspeakers base 10 tops, and there is magnetic coil 13 nearly below, the outer ring of this voice coil loudspeaker voice coil, the bottom of the nearly top connection in the outer ring of voice coil loudspeaker voice coil cylindrical shell diaphragm 15.Other has two groups of magnetosphere seats 16,17, and the base magnetosphere is controlled bass usually, left magnetosphere seat 16 is controlled middle pitch, and magnetosphere seat 17 is controlled high pitch, considers that from articulatory configuration the position that middle and high sound magnetosphere seat is provided with is higher, thereby forms the bump 18 on loud speaker surface.By diagram as seen, problems of the prior art are conspicuous as previously mentioned.
Referring to accompanying drawing 2, the structure-improved of loud speaker also comprises yoke base 20, this time yoke base 20 is provided with magnetosphere 21, this base magnetosphere also can drive voice coil loudspeaker voice coil 22 and cylindrical shell diaphragm 23 equally, structure improved feature is, along yoke base 20 is interior central down, be provided with an alcove 24 in the scope of former voice coil loudspeaker voice coil 22, can be in this alcove 24, inserting magnet piece 25, magnet piece 25 can be used the material of neodymium iron boron and so on, between the internal perisporium of magnet piece 25 and alcove 24, suitable gap 26 is arranged, another voice coil loudspeaker voice coil 27 of assembling and a diaphragm 28 that upwards swells in this gap 26, nearly below, the outer ring of voice coil loudspeaker voice coil 27 is provided with relevant magnetic coil 29.
In the loud speaker outside outside the magnetosphere seat of bottom protecting cover 32, predeterminable partial (frequently) is with electric capacity 30, with loud speaker and connect, the appearance value of suitably selecting electric capacity has an effect it to adjust the loud speaker partial when specific high frequency.In the appropriate position of inside loudspeakers cylindrical shell diaphragm 23, be provided with one and screen with cover plate 31.
The utility model is owing to insert another small-sized magnet piece and relevant voice coil loudspeaker voice coil, diaphragm thereof in advance in the end of prior art magnetic support, with vibration pronunciation by a small margin, except sending smoothly the basic, normal, high sound, through the reality test, its magnetic-force density can be increased to 9700 Gausses by 8000 Gausses when bass; During high pitch, be increased to 14000 Gausses by 12000 Gausses, and the magnetosphere sound press can increase to 90dB by 88dB when bass, increase to 95dB by 92dB during high pitch.
Referring to accompanying drawing 3,23 is the cylindrical shell diaphragm among the figure, and 22 is voice coil loudspeaker voice coil, and 28 is another diaphragm, screens to cover among the figure alcove in the loud speaker central authorities with cover plate 31.30 is electric capacity among the figure, and 32 is outer protecting cover.
The utility model can replace multiple seat type loud speaker of the prior art, and its structure is simplified greatly, and cost effectively reduces, and whole loud speaker can form an even curface, is convenient to install and fix.
Claims (3)
1, a kind of structure-improved of loud speaker, comprise by magnetosphere seat at the bottom of the following yoke that descends yoke base and magnetosphere to form and the voice coil loudspeaker voice coil and the cylindrical shell diaphragm that can be driven sounding, it is characterized in that: centre has an alcove in the described base voice coil loudspeaker voice coil, have magnet piece to insert in the alcove, the gap location that forms between the internal perisporium of magnet piece and alcove is assembled with another voice coil loudspeaker voice coil and can drives another diaphragm of pronunciation.
2, the structure-improved of loud speaker according to claim 1 is characterized in that also comprising electric capacity and loud speaker and connects.
3, the structure-improved of loud speaker according to claim 1 is characterized in that described another diaphragm top, is provided with the cover plate of screening in the cylindrical shell diaphragm.
