Description
Technical field
The utility model is related to a kind of sound-producing device, the more particularly to magnetic circuit device of loudspeaker.
Background technology
The distortion of loudspeaker refer to loudspeaker occur in that when playback audio signal it is inconsistent with former audio signal
Sound a kind of phenomenon.The quality of loudspeaker tonequality depends entirely on its distortion situation, therefore how to reduce loudspeaker
Distortion is formed into an important research direction of high-performance high-fidelity loudspeaker.
Loudspeaker distortions are also known as the askew rate of high harmonic, from the sound that loudspeaker radiate, ought to there was only the weight of institute's plus signal
It is existing, but in the sound for actually radiating in addition to fundamental frequency signal sound, also the sound of other frequencies occurs, and sounds sound
There is abnormal sensation, this phenomenon is distortion.
The magnetic circuit system of loudspeaker is to provide the pith of driving force for the diaphragm of loudspeaker, while being also the main of distortion
Source.Substantially, voice coil loudspeaker voice coil changes quite greatly the amplitude of voice coil loudspeaker voice coil to the relative position of magnetic gap, makes magnetic material first in low-frequency range
Average magnetic conductivity change affects the inductance of voice coil loudspeaker voice coil, makes electric current produce distortion, is especially particularly acute at resonant frequency point F0.Its
Magnetic flux is produced when secondary voice coil loudspeaker voice coil is by electric current, the magnet magnetized of composition magnetic circuit is made, the magnetization construction particularly with hysteresis curve
Material, therefore produce current distortion.Furthermore, the induction reactance of loudspeaker increases with frequency and rises rapidly, causes in loudspeaker level pressure
Loudspeaker high frequency deep fades in the case of input, so as to affect the playback of high-frequency signal.
Utility model content
According to one side of the present utility model, there is provided magnetic path unit of speaker, loudspeaker distortions are effectively reduced.
Magnetic path unit of speaker of the present utility model, including washer, magnet, T iron, voice coil loudspeaker voice coil and becket.
Wherein, T iron includes horizontal columns and intermediolateral column, and intermediolateral column is located at the top that level is lived；Washer, magnet are ring-type, from
On be down sequentially overlapped on T iron intermediolateral columns.
Wherein, becket has mesopore, is enclosed within the intermediolateral column top of T iron props.
Further, becket is H-shaped, and becket is copper ring.
Washer forms toroid gap with the intermediolateral column outside of T iron, and voice coil loudspeaker voice coil is located in toroid gap.
Becket on T iron props plays a part of secondary coil, and the equivalent inductance that can make voice coil loudspeaker voice coil is substantially reduced, therefore
Increase of the electrical impedance of loudspeaker in high frequency no longer with frequency substantially rises, therefore can improve the high frequency radiation of loudspeaker.
Operationally, the coil of its voice coil loudspeaker voice coil can depart from the effective range of copper ring to loudspeaker in motion process, cause short-circuited conducting sleeve to have
Effect ground suppresses the voice coil loudspeaker voice coil induction reactance produced during voice coil loudspeaker voice coil energization motion, and voice coil loudspeaker voice coil induction reactance constantly rises with the change of frequency, so as to lead
Harmonic distortion is caused to increase, copper ring adopts the design of H shape, it is ensured that voice coil loudspeaker voice coil is during up-down vibration without departing from copper ring
Effective range, effectively reduce harmonic distortion generation.
Magnetic path unit of speaker of the present utility model also includes aluminium ring, and aluminium ring is connected to the lower section of the washer of voice coil loudspeaker voice coil side.
The aluminium ring of washer bottom plays a part of to reduce second harmonic distortion.
The horizontal columns mid portion of T iron bends downwards.
The recess of one V-arrangement is arranged at the intermediolateral column top of T iron.
T iron bottom plays a part of to increase voice coil loudspeaker voice coil amplitude using the design of bending downwards, it is ensured that in the case of powerful
Voice coil loudspeaker voice coil will not encounter T iron bottom and produce abnormal sound.The V-shaped part that T iron top is removed is the material saturation in order that annex, thus
The non-linear of material permeability is reduced, third harmonic distortion can be efficiently reduced.
To sum up, magnetic path unit of speaker of the present utility model, significantly reduces the distortion of loudspeaker.
Description of the drawings
Fig. 1 is the section of structure of the magnetic path unit of speaker of the embodiment of the utility model one；
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 show schematically show according to a kind of magnetic path unit of speaker of embodiment of the present utility model.As schemed
Show, the magnetic path unit of speaker, including washer 1, magnet 2, T iron 3, voice coil loudspeaker voice coil 4 and becket 5.
Becket 5 is H-shaped copper ring.
T iron 3 includes horizontal columns and intermediolateral column, and intermediolateral column is located at the top that level is lived；Washer 1, magnet 2 are ring-type, from upper
Down it is sequentially overlapped on the intermediolateral column of T iron 3.
Wherein, H-shaped copper ring has mesopore, is enclosed within the intermediolateral column top of the post of T iron 3.
Washer 1 forms toroid gap with the intermediolateral column outside of T iron 3, and voice coil loudspeaker voice coil 4 is located in toroid gap.
H-shaped copper ring on the post of T iron 3 plays a part of secondary coil, and the equivalent inductance that can make voice coil loudspeaker voice coil 4 is substantially reduced,
Therefore increase of the electrical impedance of loudspeaker in high frequency no longer with frequency substantially rises, therefore can improve the high frequency spoke of loudspeaker
Penetrate.Operationally, the coil of its voice coil loudspeaker voice coil 4 can depart from the effective range of copper ring to loudspeaker in motion process, cause short-circuited conducting sleeve not
The induction reactance of voice coil loudspeaker voice coil 4 produced during the energization motion of voice coil loudspeaker voice coil 4, the induction reactance of voice coil loudspeaker voice coil 4 can be effectively suppressed constantly to rise with the change of frequency,
So as to cause harmonic distortion to increase, copper ring adopts the design of H shape, it is ensured that voice coil loudspeaker voice coil 4 will not during up-down vibration
Depart from the effective range of copper ring, effectively reduce the generation of harmonic distortion.
Magnetic path unit of speaker of the present utility model also includes aluminium ring 6, and aluminium ring 6 is connected under the washer 1 of the side of voice coil loudspeaker voice coil 4
Side.
The aluminium ring 6 of the bottom of washer 1 plays a part of to reduce second harmonic distortion.
The horizontal columns mid portion of T iron 3 bends downwards.
The recess of one V-arrangement is arranged at the intermediolateral column top of T iron 3.
The bottom of T iron 3 plays a part of to increase the amplitude of voice coil loudspeaker voice coil 4 using the design of bending downwards, it is ensured that in powerful situation
Lower voice coil loudspeaker voice coil 4 will not encounter the bottom of T iron 3 and produce abnormal sound.The V-shaped part that the top of T iron 3 is removed is the material saturation in order that annex,
The non-linear of material permeability is which reduces, third harmonic distortion can be efficiently reduced.
To sum up, magnetic path unit of speaker of the present utility model, significantly reduces the distortion of loudspeaker.
The above is only a kind of embodiment of the present utility model, it is noted that for those of ordinary skill in the art
For, on the premise of design is created without departing from the utility model, some similar deformations and improvement can also be made, these
Should be regarded as within protection domain of the present utility model.
