Abstract
The utility model relates to a back spilling middle sound signal adsorption middle- low sound speaker, which comprises a pot frame, a surface diaphragm fixed with the pot frame, a speaker coil frame fixed with the diaphragm, a speaker coil and a centering support chip fixed with the speaker coil frame, a magnetizer at the back of the speaker, a ring magnet fixed with the magnetizer, a concentrating flux plate at the upper of the ring magnet and a phase cone fixed with the magnetizer and positioned at the centre of the speaker diaphragm, wherein, a sound-absorbing layer made of sound-absorbing material is positioned between the diaphragm and the centering support chip. By adding the sound-absorbing material between the prior middle low sound speaker diaphragm and the centering support chip, the spill of the back middle sound in the middle-low sound speaker is obviously reduced; meanwhile, the sound-absorbing layer is also used as a second centering support chip, the linearity range of the speaker is improved objectively. The middle-low sound speaker has the back spilling middle sound absorbing performance, when the bass reflex sound box uses the speaker, the relative structure of filtering the middle-low sound is simplified or omitted, so the sound box structure is simplified.
Description
Technical field
The utility model relates to loud speaker (loudspeaker), is specially the excessive absorption medium and low spectrum loudspeaker of midrange signals in a kind of back.
Background technology
Existing awl basin medium and low spectrum loudspeaker comprise basin frame, the surperficial vibrating diaphragm that is connected with the basin frame, with the fixing sound ring frame of vibrating diaphragm, with fixing voice coil loudspeaker voice coil and the centring disk of sound ring frame, also comprise the magnetic conductor that is positioned at the loud speaker rear portion, with the magnetic conductive board on the fixing ringshaped magnet of magnetic conductor, ringshaped magnet top and with the fixing phase place awl that is positioned at diaphragm of loudspeaker middle part of magnetic conductor.Behind the tone currents excitation voice coil loudspeaker voice coil (being coated within the magnetic field), can produce according to music or sound rhythm toward covering motion and driving sound ring frame, centring disk and vibrating diaphragm and together produce vibration, vibration by vibrating diaphragm sends out sound wave, and therefore electric energy is partly converted to acoustic energy.Form the space between the vibrating diaphragm of existing awl basin medium and low spectrum loudspeaker and the centring disk, the midrange signals that the loud speaker rear produces can be passed this space and be overflowed from the loud speaker rear portion, the sound reflecting meeting that reaches between vibrating diaphragm and the centring disk between vibrating diaphragm and the basin frame simultaneously forms standing wave, influences the definition of playback sound.When the awl basin loudspeaker was used for phase inverted cabinet, the part midrange signals of overflowing was interfered through the paraphase hole of audio amplifier and the acoustical signal of audio amplifier the place ahead output, because phase place there are differences, causes phase inverted cabinet middle pitch definition variation.For overcoming the relatively poor problem of middle pitch definition that phase inverted cabinet exists, at present, the main way that adopts the structure of improving audio amplifier as in additional sound-absorbing material or the audio amplifier interlock circuit midrange signals amplifying circuit is set in audio amplifier, improves the middle pitch definition of phase inverted cabinet with this.
Summary of the invention
The utility model overflows after solving and having medium and low spectrum loudspeaker part midrange signals now, thereby causes the relatively poor problem of phase inverted cabinet middle pitch definition of using existing medium and low spectrum loudspeaker, provides a kind of back the excessive absorption medium and low spectrum loudspeaker of midrange signals.
The utility model is to adopt following technical scheme to realize: the absorption medium and low spectrum loudspeaker of midrange signals overflows in the back, comprise basin frame, the surperficial vibrating diaphragm that is connected with the basin frame, with the fixing sound ring frame of vibrating diaphragm, with fixing voice coil loudspeaker voice coil and the centring disk of sound ring frame, be positioned at the loud speaker rear portion magnetic conductor, with the magnetic conductive board on the fixing ringshaped magnet of magnetic conductor, ringshaped magnet top and with the fixing phase place awl that is positioned at diaphragm of loudspeaker middle part of magnetic conductor, between vibrating diaphragm and centring disk, be provided with the sound absorbing layer of making by sound-absorbing material.This sound absorbing layer absorbs the middle pitch composition that overflow at the vibrating diaphragm rear.
Prior art is to solve the unclear problem of phase inverted cabinet middle pitch tonequality by changing the audio amplifier self structure, and the utility model is started with from this body structure of loud speaker, by between existing medium and low spectrum loudspeaker vibrating diaphragm and centring disk, setting up sound absorbing layer, can significantly reduce overflowing of medium and low spectrum loudspeaker rear middle pitch composition; Simultaneously, this sound absorbing layer also plays the effect of second centring disk, has objectively improved the range of linearity of loud speaker again.Loud speaker described in the utility model is owing to self have the back middle pitch absorption function that overflows, and when phase inverted cabinet uses this loud speaker, can simplify or save the required corresponding construction of middle pitch that overflows after the filtering, thereby make the simple in structure of audio amplifier.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
The absorption medium and low spectrum loudspeaker of midrange signals overflows in the back, comprise basin frame 1, with the fixing surperficial vibrating diaphragm 2 of basin frame, with the fixing sound ring frame 3 of vibrating diaphragm, with fixing voice coil loudspeaker voice coil 4 and the centring disk 5 of sound ring frame, be positioned at the loud speaker rear portion magnetic conductor 6, with the magnetic conductive board 8 on the fixing ringshaped magnet 7 of magnetic conductor, ringshaped magnet top and with the fixing phase place awl 9 that is positioned at diaphragm of loudspeaker middle part of magnetic conductor, between vibrating diaphragm and centring disk, be provided with the sound absorbing layer of making by sound-absorbing material 10.Basin frame 1 is fixing with the magnetic conductive board 8 on magnet top, and the inwall of the other end of centring disk 5 and basin frame is fixed.
Sound absorbing layer 10 can adopt sound-absorbing materials such as acoustical cotton, glass fibre, porous polyurethane.Sound absorbing layer outer surface and the adhesion of basin frame inwall, thus make the sound absorbing layer location, prevent that vibrating diaphragm contacts with sound absorbing layer in the loud speaker voiced process.
The inner surface of sound absorbing layer 10 and sound ring frame 3 adhesions.Like this, to the sound absorbing layer location, sound absorbing layer 10 also can play the effect of second centring disk, has objectively improved the range of linearity of loud speaker again except that better.
For further absorbing the midrange signals that overflow at the medium and low spectrum loudspeaker rear, be pasted with wool at the back side of vibrating diaphragm 2.
