Embodiment 1

[0017] Refer to figure 1 , figure 2 As shown, the speaker optimized for audio frequency processing of the present invention includes a ring magnet 1, a T iron 2 and a voice coil 3. On the outer side of the ring magnet 1, there are eight sets of additional coils 4 that generate additional magnetic fields. The intensity of the generated magnetic field is basically the same and is evenly distributed along the side of the ring magnet 1; the power supply of the additional coil 4 comes from the frequency divider circuit, so that the current frequency is basically the same as the current frequency of the voice coil 3.

Embodiment 2

[0019] Refer to image 3 As shown, another audio-optimized speaker of the present invention is basically the same as the first embodiment, except that four sets of additional coils 4 are arranged on the inner side wall of the ring magnet 1.

[0020] The specific method of use of the present invention is to sample the audio signal from the audio source (audio power amplifier) ​​at each frequency in the last one-fifth to one-tenth of the response time of the original speaker's voice coil action through the frequency divider circuit system And amplify the current signal. After processing in this way, the instantaneous control signal (pulse signal) of the additional coil 4 is obtained. After the control signal is input into each winding of the additional coil 4 at the same time, a certain degree of magnetic field lines of the ring magnet 1 are generated. Intervention, in this way, controls the force of the speaker voice coil 3, thereby interfering with the amplitude of the diaphragm, ...

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 [0001] The present invention relates to a loudspeaker, more specifically, it relates to a loudspeaker with audio frequency optimization processing. Background technique [0002] When the voice coil-diaphragm component of the loudspeaker is working, the "spike" characteristic of its push-pull motion makes the human ear feel that the sound is lack of elasticity and beauty, and is prone to fatigue. The original technology to solve this problem is to increase the tensile damping coefficient by increasing the physical elastic strength of the folding ring at the connection between the diaphragm and the outer bracket of the speaker, or to increase the rear of the diaphragm (that is, the inner direction of the speaker) closer to the diaphragm by delaying The strength of the nearby air pressure can be solved by increasing the damping coefficient of the diaphragm movement. However, this kind of solution can easily cause instantaneous distortion of the original shape of the...
