Embodiment 1

[0039] like image 3 As shown, in this embodiment, the magnetic structure of the loudspeaker includes two coil groups, that is, the first coil group 111 and the second coil group 112, and the two coil groups are provided with a vibration space. During use, by changing the input of the first coil set 111 and the second coil set 112 , the sounding direction of the speaker can be changed.

[0040] Specifically, when the signal input terminal of the first coil group 111 inputs a power signal, and the signal input terminal of the second coil group 112 inputs a sound signal, the sounding direction of the speaker is downward; when the signal input terminal of the first coil group 111 inputs sound signal, and when the signal input end of the second coil group 112 receives a power signal, the direction of the speaker's sound is upward.

Embodiment 2

[0042] like Figure 4 As shown, on the basis of the first embodiment above, the first coil set 121 is composed of two sub-coil sets 1211 . In this embodiment, by changing the input of the first coil group 121 and the second coil group 122, in addition to changing the direction of the sound, the frequency of the sound can also be changed.

[0043] Specifically, when the signal input terminal of the first coil group 121 inputs a power signal, and the signal input terminal of the second coil group 122 inputs a sound signal, the sounding direction of the loudspeaker is downward, and at this time, the vibration of the second coil group 122 is also more Stable, which can improve the sound quality of the sound played by the speaker. And when the signal input terminal of the first coil group 121 inputs the sound signal, and the signal input terminal of the second coil group 122 inputs the power signal, the two sub-coil groups 1211 of the first coil group 121 vibrate and sound, the so...

Embodiment 3

[0045] like Figure 5 As shown, in this embodiment, the magnetic structure of the loudspeaker includes three coil groups, that is, the first coil group 131 , the second coil group 132 and the third coil group 133 , and the three coil groups are provided with a vibration space. In this embodiment, by changing the input of the three coils, the direction of the sound of the speaker can be changed, and the intensity of the sound can also be changed.

[0046] For example, when sound signals are input to the signal input ends of the first coil set 131 and the third coil set 133 , and sound signals are input to the signal input end of the second coil set 132 , the speaker has two sound emitting directions. And when the signal input terminals of the first coil group 131 and the third coil group 133 input power signals, and the signal input terminals of the second coil group 132 input sound signals, the speaker has only one sound direction, but its sound intensity will be enhanced.

Abstract

The invention relates to a magnetic structure of a loudspeaker, which comprises more than two coil groups prepared by adopting a PCB technology or a semiconductor technology, the more than two coil groups are arranged in sequence, and at least one coil group is provided with a vibration space; each coil group is provided with a signal input end which is connected with a sound signal or a power signal. When the loudspeaker is used, the signal input end of each coil group selectively inputs a sound signal or a power supply signal according to actual use requirements, so that the sound productiondirection or the sound production intensity of the loudspeaker is changed, and the use flexibility of the loudspeaker is improved.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a magnetic structure of the loudspeaker. Background technique [0002] The loudspeaker is an important acoustic component in electronic equipment, and it is a transducer device that converts electrical signals into acoustic signals. [0003] The magnetic structure of the current loudspeaker generally includes a magnet, a wire coil, and a diaphragm connected to the wire coil. The coil is energized to generate a magnetic field, thereby causing the force of the coil in the magnetic field of the magnet to change. , the force on the coil will also change, resulting in vibration, and at the same time, the diaphragm connected to the coil will also vibrate, thereby making a sound and completing the conversion from electrical signal to acoustic signal. [0004] When the current loudspeaker is produced, the sound intensity, sound direction and sound frequency are fixed, and cannot be changed a...
