Description
Technical field
The present invention relates to speaker system, specifically a kind of reduction distortion changes characteristic speaker system and its system
Make method.
Background technology
Speaker system is commonly called as speaker, is the capital equipment in sound recovery system, its quality height decides entire
The quality of sound recovery system sound quality.Existing speaker system is broadly divided into following two：One is active loudspeaker systems, separately
One is passive loudspeaker systems.Wherein, it is following two that passive loudspeaker systems, which are divided into,：One is using closed box structure
Passive loudspeaker systems, another kind are the passive loudspeaker systems using paraphase box structure.However practice have shown that, either which
Kind passive loudspeaker systems all have that total harmonic distortion is big, frequency linking difficulty is big.
Total harmonic distortion is greatly mainly as caused by following four factor：One, distortion caused by loud speaker itself：1）It raises one's voice
Distortion caused by device cone is in uneven thickness：It is uneven due to cone thickness, when electric signal pushes voice coil to drive cone vibration
When, the part bending change of cone thickness is small, and thin part bending change is big, and loud speaker output at this time is a modified sound
Wave.2）Distortion caused by loud speaker magnetic gap magnitude of field intensity difference：The magnetic gap of loud speaker is made of magnetic conductive board and iron core, magnetic conduction
The thickness of plate is certain, and the width of voice coil conductor part is also certain.It is transported between magnetic gap when voice coil is pushed by electric signal
When dynamic, if the magnetic field intensity of magnetic gap is big, electric signal is big to the motive force of voice coil, if the magnetic field intensity of magnetic gap is small, electric signal
It is small to the motive force of voice coil.When voice coil is by big motive force, the Oscillation Amplitude of cone can increase, when voice coil conductor part
After width has exceeded the thickness of magnetic conductive board, the magnetic field intensity in the region small into magnetic gap magnetic field intensity, magnetic gap reduces to voice coil
Motive force just reduces, and loud speaker output at this time is a sound wave being distorted.3）Distortion caused by loudspeaker support resonance：It raises one's voice
The holder of device is molded by steel plate punched or casting and forming.After loud speaker is pushed by big electric signal, the Oscillation Amplitude of cone
It increases, no matter any holder all can generate mechanical resonance under specific frequency and Oscillation Amplitude, cause loudspeaker support
Mechanical resonance is distorted.The above distortion there are one common ground, be exactly diffuser Oscillation Amplitude it is bigger, the distortion of generation is got over
Greatly.Two, distortion caused by body structure：The babinet of existing passive speaker system is square structure mostly.It can from physical principle
Know, the sound wave that loud speaker is sent out is spread in air in the form of spherical wave.When the sound wave that loud speaker rear end is sent out is rectangular
Babinet in when spreading, just will produce the physical phenomenons such as refraction, reflection, so that sound wave is become disorderly and unsystematic, produce body structure
Distortion.Three, distortion caused by babinet mechanical resonance：The babinet of passive loudspeaker systems is not a very big object of the scale of construction
Body, and its babinet is made of board-like material, so this constitute the smaller babinet of the scale of construction by board-like material, is being raised one's voice
Mechanical resonance is just will produce under the vibration of device.Its mechanical resonance frequency, is just happened within audiorange.Four, passive to raise one's voice
Distortion caused by device system mounting means：In the characteristic curve of test loudspeaker, to be tested under the conditions of standard baffle, be for
Overcome so-called acoustic short circuit.This so-called acoustic short circuit is the physics that loud speaker generates under complete free-field condition in fact
Phenomenon.When applying positive electric signal to loud speaker, cone vibrates forward, and cone vibrates backward when applying negative signal to loud speaker,
At this time at the edge of loud speaker, vibration forward and backward the air supplement of vibration acoustic will be formed, the defeated of loud speaker front end is made
Pressure drop of speaking is low, thus produces so-called acoustic short circuit.But loud speaker sound wave output at this time, in loud speaker parallel lines direction,
There is one group of sound wave for being different from loud speaker front-end and back-end.Since this group of sound wave contains the sound wave forwardly and rearwardly vibrated, it is
The sinusoidal combination sound wave for thering is sound wave to bear string signal again of one existing sound wave, so this group of sound wave is not only true but also real.External someone
Just using loud speaker this feature, a kind of speaker of not babinet is invented, is three groups of loud speaker parallel devices in circular net
In cage, every group of two units are installed face-to-face, and layering is fixed on holder.From above example as can be seen that loud speaker not only to
Before send out sound wave, similarly send out sound wave backward.But the sound wave that traditional technology to the back-end sends out loud speaker is obstructed in case
In vivo, even if the guiding aperture apparatus of some phase inverting box is in speaker front end, its output sound wave is also a mixed and disorderly sound wave.And
The sectional area of pilot hole is less than the surface area of diffuser, and the sound wave being directed to out is the one small of loud speaker rear end sound wave
Part, which forms distortions caused by passive loudspeaker systems mounting means.
It is mainly as caused by following three kinds of factors that frequency, which is connected difficulty greatly,：One, in the design of passive loudspeaker systems,
Need to determine the geometric dimension of babinet first.After the geometric dimension of babinet determines, loud speaker is combined with babinet will form one
The new characteristic curve of group, and this group of characteristic curve is not inconsistent standardization requirement once, changing it is difficult.Two, passive speaker
The linking of system frequency will use frequency divider, and the capacitance and inductance in frequency divider all have phase shift effect to AC signal.This shifting
Phase separation can generate phase difference around the part-frequency point of frequency divider, these phase differences can form big distortion piece, increase system
The distortion factor.In addition, after using these devices, the characteristic curve of speaker system can be changed, also increase and hold in the mouth between frequency
The difficulty connect.Three, it in the design of three frequency division passive loudspeaker systems, needs to use dedicated Squawker, but middle pitch is raised
The output power of sound device is all smaller, and sensitivity is also relatively low, its characteristic curve is difficult and woofer and tweeter
The frequency of device is connected.In addition, after using multiple loud speakers, the sound wave that their rear ends are sent out can interfere with each other in babinet, make nothing
The characteristic curve of source speaker system is more difficult to determine, also just further increases the difficulty being connected between frequency.
Based on this, it is necessary to a kind of completely new speaker system is invented, to solve the total harmonic wave of existing passive speaker system
The problem that distortion is big, frequency linking difficulty is big.
Invention content
The present invention carries to solve the problems, such as that existing passive speaker system total harmonic distortion is big, frequency linking difficulty is big
A kind of reduction distortion has been supplied to change characteristic speaker system and its manufacturing method.
The present invention adopts the following technical scheme that realization：A kind of characteristic speaker system of reduction distortion change,
Including panel, woofer, high pitch loudspeaker, Squawker, bass resonator, high pitch loudspeaker shield, middle pitch sympathetic response
Chamber；Wherein, woofer is front and back through the plate face lower part for being fixed on panel；Run through before and after high pitch loudspeaker and is fixed on panel
In the middle part of plate face；Squawker is front and back through the plate face top for being fixed on panel；Bass resonator is that front end is equipped with open, rear end
Closed circular cylindrical cavity；The front end opening end face of bass resonator and the rear closed fixation in plate face lower part of panel, and bass is total
The axis of tymapanum is overlapped with the axis of woofer；High pitch loudspeaker shield is that front end is equipped with open, back-end closure box-shaped
Cover body；The front end opening end face of high pitch loudspeaker shield and the back plate Middle face of panel are fixed, and high pitch loudspeaker shield is provide with

The rear closed fixation in plate face top of front end opening end face and panel, and the axis weight of the axis of middle pitch resonator and Squawker
It closes；The volume of middle pitch resonator is less than the volume of bass resonator.
When work, due to be between woofer and bass resonator it is closed be connected to, and bass resonator be cylinder
Cavity so that bass resonator forms an air spring.Similarly, due to being close between Squawker and middle pitch resonator
Connection is closed, and middle pitch resonator is circular cylindrical cavity so that middle pitch resonator forms an air spring.Work as woofer
（Squawker）Cone when vibrating forward, air spring is applied with a reaction suction to cone, makes the vibration of cone
Amplitude reduction gets off.Work as woofer（Squawker）Cone when vibrating backward, air spring is applied with one to cone
A resistance also reduces the Oscillation Amplitude of cone.Due to the effect of air spring, no matter cone vibrates forward or backward
Vibration, it is all by a parallel direction power（Reaction suction or resistance）.Therefore, the non-uniform bending change of cone thickness
It is basic to disappear, also just basic disappear is distorted caused by diffuser is in uneven thickness.Meanwhile in the effect of air spring
Under, the part of voice coil conductor width is controlled the range big in magnetic gap magnetic field intensity to the maximum extent, is also made because of loud speaker magnetic gap
Basic disappear is distorted caused by magnitude of field intensity difference.Further, since the Oscillation Amplitude of cone reduces, also make because raising one's voice
Distortion is basic caused by the resonance of device holder disappears.In above process, as a result of middle pitch resonator, make Squawker
The choice of output power and sensitivity becomes very large, and thus makes the characteristic curve and high pitch loudspeaker of woofer
Characteristic curve is easy to link up, and is connected difficulty to reduce frequency.Based on the above process, with existing passive loud speaker system
System is compared, and a kind of characteristic speaker system of reduction distortion change of the present invention is on the one hand big by brand new
Width reduces total harmonic distortion, on the other hand greatly reduces frequency linking difficulty, thus efficiently solves existing passive and raise one's voice
The problem that device system total harmonic distortion is big, frequency linking difficulty is big.Experiments have shown that in input power 1W, inputting frequency 100Hz's
Under situation, the distortion factor of existing passive speaker system is up to 25.6%, and a kind of reduction distortion of the present invention changes characteristic
