Abstract
A drive of belt tweeter consists of a front yoke, a rear yoke, magnetic strips, a voice membrane module, a gasket and a stent. The front yoke and the rear yoke are both provided with magnetic strips at two sides of the stent to clamp the voice membrane module, the speech coil of which is pressed on a high temperature resistant diaphragm and clamped between two voice membrane splints to form a voice membrane integrative structure; the drive is provided with high magnetic permeability front and rear yokes and high performance permanent magnetic strips, the magnetic strips are adhered to the yokes and combine with the voice membrane module into a push-pull type structure. The drive of belt belt tweeer of the utility model has high sensitivity and flat and wide high-frequency response.
Description
The utility model relates to a kind of driver of loud speaker, especially a kind of driver that is used for tweeter.
Along with the raising of people's artistic appreciation and Music Appreciation level, audio frequency simulation turns to digitlization, and the digitized audio carrier requires the transient distortion of loudspeaker little, the resolution height, and the straight broadness of high frequency response, and ribbon tweeters possesses the loud speaker of these characteristics just.Ribbon tweeters the eighties abroad begins development mid-term, but be subjected to the restriction of material industry at that time, these two kinds of high-tech made difficulty of particularly anti-300 ℃ of high temperature vibrating diaphragms and high-performance permanent magnet are very big, therefore, ribbon tweeters rests on conceptual phase all the time, does not slowly enter suitability for industrialized production.The sound membrane module of making by high temperature resistant vibrating diaphragm, voice coil loudspeaker voice coil and be the key components of the driver of ribbon tweeters by the magnetic circuit assembly that high-performance permanent magnet is made.Because high temperature resistant diaphragm materials does not solve, therefore, vibrating diaphragm and voice coil loudspeaker voice coil are to be divided into two always.Middle nineteen nineties, along with the basic material industrial expansion, above-mentioned two big difficult points achieve a solution.
The purpose of this utility model is to provide a kind of driver of loud speaker, and the sound membrane module is made integral structure, and is little with the transient distortion of loudspeaker that it drives, resolution height, the straight broadness of high frequency response.
For reaching this purpose, the utility model adopts following technical scheme:
Make a kind of driver of ribbon tweeters, comprise preceding magnetic conductive board, back magnetic conductive board, magnetic stripe, sound membrane module, pad and support, on the magnetic conductive board of front and back magnetic stripe is housed all, the sound membrane module is contained on the support, the both sides shell tool, the front and back magnetic conductive board is loaded on the both sides of support respectively, the sound membrane module is clipped in the middle, global shape is a strip, this sound membrane module is made of two sound film clamping plate, high temperature resistant vibrating diaphragm and voice coil loudspeaker voice coils, voice coil loudspeaker voice coil is compressed on the high temperature resistant vibrating diaphragm, and is clipped between two sound film clamping plate, makes sound film integral structure; This driver has the front and back magnetic conductive board and the high-performance permanent magnetism magnetic stripe of high permeability, uses binding agent that magnetic stripe neatly is bonded on the magnetic conductive board by polarity, and is combined into the push-pull type structure with the sound membrane module.
1～3 magnetic stripe that respectively bonds on the magnetic conductive board of described front and back has louvre between two magnetic stripes of preceding magnetic conductive board.
Voice coil loudspeaker voice coil nominal impedance on the described sound membrane module is 7.5～8.5 Ω.
Also set up damping layer between the sound membrane module of described driver and the front and back magnetic conductive board.
According to the driver of the ribbon tweeters of said structure, be compressed on voice coil loudspeaker voice coil on the sound membrane module just in time between the magnetic field that magnetic stripe forms up and down, the voice coil loudspeaker voice coil cutting magnetic line produces induced current, and vibrating diaphragm constantly vibrates, and forms sound wave.Setting up damping layer is in order to make frequency response straight, to absorb mixed and disorderly sound wave.
Because the utility model adopts sound film integral structure and high-performance magnetic stripe, the belt high frequency band loudspeaker transient distortion that it is driven is little, highly sensitive, the straight broadness of high frequency response, after tested, its sensitivity 〉=92dB/mVA, high frequency response scope 3～30KHz ± 3dB.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a sectional elevation of the present utility model;
Fig. 2 is the front view of sound membrane module of the present utility model;
Fig. 3 is the front view of preceding magnetic conductive board of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.As shown in Figure 1, the utility model comprises preceding magnetic conductive board 1, support 2, pad 3, sound membrane module 4, back magnetic conductive board 5, magnetic stripe 6, damping layer 7 and screw 8, on preceding magnetic conductive board 1 and the back magnetic conductive board 5 magnetic stripe 6 is housed all, sound membrane module 4 is contained on the support 2, both sides shell tool 3, before magnetic conductive board 1 and back magnetic conductive board 5 be loaded on the both sides of support 2 respectively by screw 8, sound membrane module 4 is clipped in the middle.
The structure of sound membrane module 4 as shown in Figure 2, it is made of two sound film clamping plate 4-3, high temperature resistant vibrating diaphragm 4-2, voice coil loudspeaker voice coil 4-1 and lead-out wire 4-4, voice coil loudspeaker voice coil 4-1 is compressed on the high temperature resistant sound film 4-2, and is clipped between two sound film clamping plate 4-3, and lead-out wire 4-4 is divided into two of , .The nominal impedance of present embodiment voice coil loudspeaker voice coil 4-1 is 8 Ω.
The structure of magnetic conductive board before Fig. 3 shows, on preceding magnetic conductive board 1, be bonded with magnetic stripe 6,3 magnetic stripes are arranged on the preceding magnetic conductive board 1 of present embodiment, between two magnetic stripes 6, have louvre 1-3,1-1 among Fig. 3 is a location hole, 1-2 is an installing hole, and screw 8 is exactly to link together by magnetic conductive board 1,5 and sound membrane module 4 before and after these installing holes 1-2 dress.The structure of back magnetic conductive board 5 is identical with preceding magnetic conductive board 1 cardinal principle.
