Abstract
The invention discloses a loudspeaker with optimized audio frequency, belonging to the technical field of loudspeakers. The essential technical scheme is that the loudspeaker with the optimized audio frequency comprises an annular magnet, a T-iron and a voice coil, wherein the lateral side of the annular magnet comprises at least three groups of interpole coils for producing complementary field, and the magnetic field produced by each group of the interpole coils basically has the same intensity and is evenly distributed along the lateral side of the annular magnet. The invention has simple structure, can improve loudspeaker acoustic effect, and is used in audio signal playing.
Description
Technical field
The present invention relates to a kind of loud speaker, more particularly, it relates to a kind of loud speaker of audio frequency optimization process.
Background technology
When the voice coil loudspeaker voice coil of loud speaker-vibrating diaphragm assembly was worked, " spike " characteristic of its push-pull movement made the sense of hearing of people's ear think that the elasticity of sound and aesthetic feeling lack, and is easy to generate fatigue.The original technology of head it off is promptly to increase its stretching damping coefficient by the physics elastic strength that improves vibrating diaphragm and the ring of loud speaker support arm junction, or increases vibrating diaphragm rear (being the audio amplifier internal direction) by the retardation mode and press close to the damping coefficient that near the raising vibrating diaphragm of the air pressure intensity the vibrating diaphragm moves and solve.But this class scheme is easy to cause original form of voice coil loudspeaker voice coil-vibrating diaphragm assembly to produce transient distortion and cause tonequality adversely effected.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, and a kind of loud speaker of simple in structure, the audio frequency optimization process that can improve the loud speaker sounding effect is provided.
Technical scheme of the present invention is such: a kind of loud speaker of audio frequency optimization process, comprise toroidal magnet, T iron and voice coil loudspeaker voice coil, wherein said toroidal magnet side is provided with the interpole coil that at least three groups produce complementary field, and it is basic identical and evenly distribute along the toroidal magnet side that each organizes magnetic field intensity that interpole coil produces.
Further, in the loud speaker of above-mentioned audio frequency optimization process, described interpole coil is arranged on the toroidal magnet lateral wall.
In the loud speaker of above-mentioned audio frequency optimization process, described interpole coil also can be arranged on the toroidal magnet madial wall.
In the loud speaker of above-mentioned audio frequency optimization process, the power frequency of described interpole coil and the power frequency of voice coil loudspeaker voice coil are basic identical.
After the present invention adopts said structure, compared with prior art, have following advantage:
By many group interpole coils are set in toroidal magnet side balance, the magnetic field that interpole coil energising back is produced will produce the intrinsic magnetic line of force of former loudspeaker unit intervenes, also promptly to the magnetic field generation enhancing of toroidal magnet or the effect that slackens, thereby have influence on the push-pull effort of loudspeaker voice coil, reach the amplitude that changes vibrating diaphragm and recommend action (change waveform), more to adapt to the sense of hearing characteristic of people's ear; Said structure of the present invention both can guarantee that the vibrating diaphragm of loud speaker worked under indeformable state, reduce the distortion of loud speaker, can improve the tonequality of the diaphragm of loudspeaker again; Perhaps adding the power output that can improve loud speaker under the state of high-intensity magnetic field, the power that bears that improves loud speaker.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of the another kind of specific embodiment of the present invention.
Fig. 4 is the present invention and traditional voice coil loudspeaker voice coil displacement curve contrast schematic diagram.
Among the figure: toroidal magnet 1, T iron 2, voice coil loudspeaker voice coil 3, interpole coil 4.
Embodiment
Consult Fig. 1, shown in Figure 2, the loud speaker of audio frequency optimization process of the present invention, comprise toroidal magnet 1, T iron 2 and voice coil loudspeaker voice coil 3, be provided with eight groups of interpole coils 4 that produce complementary fields at the lateral surface of toroidal magnet 1, each magnetic field intensity that produces when organizing interpole coil 4 work is basic identical and evenly distribute along toroidal magnet 1 side; The power supply of interpole coil 4 makes the power frequency of power frequency and voice coil loudspeaker voice coil 3 basic identical from the frequency divider circuit.
Consult shown in Figure 3, the loud speaker of another kind of audio frequency optimization process of the present invention, substantially the same manner as Example 1, different is that four groups of interpole coils 4 are arranged on toroidal magnet 1 madial wall.
Concrete using method of the present invention is, by the frequency divider line system to sampling and amplify this current signal in last 1/5th to 1/10th times of former loudspeaker voice coil action response time by every kind of frequency from the audio signal of source of sound (audio-frequency power amplifier), after dealing with like this, obtain the moment controlling signal (pulse signal) of interpole coil 4, after this controlling signal imported interpole coil 4 each winding respectively simultaneously, 1 intrinsic magnetic line of force of toroidal magnet has been produced intervention to a certain degree, so just controlling the stressed of loudspeaker voice coil 3, thereby the amplitude of intervening vibrating diaphragm, influence and changed it and originally recommend action, make its purpose, reach the sound waveform that generation more adapts to people's ear sense of hearing characteristic according to design.Consult shown in Figure 4, the displacement curve A of voice coil loudspeaker voice coil 3 is without situation about improving among the figure, and the displacement curve B of voice coil loudspeaker voice coil 3 is exactly an actual displacement situation after interpole coil of the present invention 4 is intervened among the figure, " spike " that voice coil loudspeaker voice coil 3 drives the push-pull movement of the vibrating diaphragms mitigation that obviously becomes; By this moment control, improve the whole tone color of loud speaker.Technical scheme cost of the present invention is low but produce effects obviously.
