Abstract
The invention belongs to a double-sided sounding frequency-dividing loudspeaker and relates to a loudspeaker for sounding by driving positive-negative alternating audio signals by an electromagnetic force generated by audio coils and eudipleural diaphragms connected with the audio coils to vibrate the air. The invention adopts the work principle that the audio signals are input into the audio coils through which a magnetic force line of a magnetic field passes, the eudipleural diaphragms are driven by the electromagnetic force generated by the audio coils to vibrate and the vibration direction and the magnitude of the eudipleural diaphragms are controlled by the audio signals in the audio coils, so that the aim of electroacoustic transformation can be achieved and the double-sided sounding frequency-dividing loudspeaker gives out sound. The invention overcomes the defect that audio coils of the generally-used electric loudspeaker are suspended in the middle of the magnetic and the acoustic pressures generated by conical diaphragms connected with the audio coils are asymmetrical, realizes the flat structure of the loudspeaker and can realize that the double-sided diaphragms of one loudspeaker do not intervene each other and send out high, middle and low sounds with an acoustic axis.
Description
Technical field
The invention belongs to a kind of double-sided sounding frequency-dividing loudspeaker, be particularly related to a kind of have the audio signal of positive and negative alternation independently born electromagnetic force from the voice coil that is connected with left and right sides vibrating diaphragm separately by symmetrical vibrating diaphragm convert vibration to air, thereby realize the loud speaker of sounding.Double-sided sounding frequency-dividing loudspeaker of the present invention realizes that the layout feature of the air vibrating diaphragm of electroacoustic conversion is that the air vibrating diaphragm concentric-ring pattern left-right symmetric of high, medium and low sound is isolated the function that the electromagnetic force of bearing connected voice coil input separately is converted into vibrate air mutually.
Background technology
Many weeks, loud speaker is that the electroacoustic that all be unable to do without every day during people lived is changed modal a kind of device, since loud speaker comes out, people never were interrupted the improvement of loud speaker, but the design feature of the dynamic speaker that is generally used by countries in the world has restricted the further improvement of self at present, the just manufactured materials of the pyramid type air vibrating diaphragm of dynamic speaker that people make great efforts to change, fundamentally do not make conical air vibrating diaphragm under the effect of voice coil electromagnetic force, during the porpoise air, the pyramid type air vibrating diaphragm unequal defective of acoustic pressure that vibrate air produced that seesaws improves under the prerequisite that electromagnetic force equates, the pyramid type air vibrating diaphragm sound wave that vibrate air produced that seesaws does not only wait in the equal acoustic pressure that electromagnetic force produced, and the sound wave that pyramid type air vibrating diaphragm is produced when moving backward will produce distortion with the support generation sound deflection of supporting pyramid type air vibrating diaphragm.
Summary of the invention
The objective of the invention is to overcome above deficiency, provide a kind of audio signal of alternation that can make when converting sound to, the positive half cycle of audio signal and negative half period are converted to the vibrating diaphragm of the left and right symmetry of air vibration are finished the electroacoustic convert task that the positive half cycle born separately and negative half period audio signal convert sound to alone bearing the electromagnetic force that voice coil is produced by voice coil, reach the acoustic pressure of left and right sides generation that vibrating diaphragm vibrates and the variation of audio signal and change synchronously, and do not produce sound deflection.Making double-sided sounding frequency-dividing loudspeaker of the present invention compare undistorted characteristic with traditional dynamic speaker is greatly improved.
The design feature of double-sided sounding frequency-dividing loudspeaker of the present invention determined voice coil be with from the audio signal of signal source according to height, in, the frequency of low different frequency section is imported the height in the double-sided sounding frequency-dividing loudspeaker of the present invention respectively, in, the bass coil, the height of double-sided sounding frequency-dividing loudspeaker of the present invention, in, the bass vibrating diaphragm, high, in, the voice coil of bass all is to isolate mutually, high, in, the magnetic field of the voice coil of bass also is to isolate mutually, high, in, the left and right sides vibrating diaphragm of bass is symmetrical, the height that double-sided sounding frequency-dividing loudspeaker of the present invention had, in, the pronunciation zone of bass, energy will be from the height of audio signal source, in, the corresponding height that is input in the double-sided sounding frequency-dividing loudspeaker of the present invention of bass signal, in, thereby the voice coil of bass reaches the sound wave that converts the non-interfering pronunciation zone at double-sided sounding frequency-dividing loudspeaker of the present invention of the audio signal of different frequency section to sound unisonance axle is propagated in air.
Double-sided sounding frequency-dividing loudspeaker of the present invention changed the present common employings of people be input to existing a plurality of dynamic speakers of electroacoustic conversion method that the high, medium and low sound loud speaker of electrodynamic type finishes high, medium and low sound respectively with different sound shaft vibration air by the high, medium and low different frequency range of audio signal source is corresponding the time sound wave intermodulation distortion that produced phenomenon.

Embodiment
With reference to accompanying drawing 1-3, No. 1 voice coil 9 of bass in the magnetic field that No. 1 magnet 10 of No. 1 magnet 8 of the bass N utmost point and the bass S utmost point is formed be connected be transfused to the audio signal of bass frequencies behind No. 2 voice coils 21 of bass in the magnetic field that No. 2 magnet of the bass N utmost point 20 and No. 2 magnet of the bass S utmost point 22 form after, because the coil polarity that No. 2 voice coils of No. 1 voice coil 9 of bass and bass 21 connect is identical, the number of turn is identical, the line footpath is identical, winding direction is identical, so No. 1 voice coil of bass 9 and No. 2 voice coils 21 of bass will produce the electromagnetic force of equidirectional simultaneously, the direction of this electromagnetic force, power is to change with the audio signal of No. 1 voice coil 9 of input and No. 2 voice coils 21 is synchronous, and No. 2 voice coils 21 of No. 1 voice coil 9 of bass and bass all are connected with bass stress equalization annulus 25 above the left side bass vibrating diaphragm 1, so effect bottom left of the electromagnetic force that left side bass vibrating diaphragm 1 will be produced along with No. 1 voice coil of bass 9 and No. 2 voice coils 21 of bass, right motion, thereby the electroacoustic of having realized bass zone transforms purpose, and double-sided sounding frequency-dividing loudspeaker bass zone of the present invention is sounded.
The electroacoustic transfer principle of the bass zone in the electroacoustic transfer principle of the bass zone on double-sided sounding frequency-dividing loudspeaker of the present invention right side and the above-mentioned double-sided sounding frequency-dividing loudspeaker of the present invention left side of narrating is identical.
The electroacoustic transfer principle of the electroacoustic transfer principle of the middle register of double-sided sounding frequency-dividing loudspeaker of the present invention, treble and the bass zone of the above-mentioned double-sided sounding frequency-dividing loudspeaker of narrating of the present invention in like manner.
The function of the tweeters diaphragms stress equalization annulus 23 middle pitch vibrating diaphragm stress equalization annulus 24 bass vibrating diaphragm stress equalization annulus 25 of double-sided sounding frequency-dividing loudspeaker is exactly to divide equally voice coil electromagnetic force stressed on vibrating diaphragm, and the suffered electromagnetic force of stress point is disperseed uniformly by the stress equalization annulus on the vibrating diaphragm.
