Abstract

The utility model relates to a speaker technical field especially relates to an increase speaker of low frequency channel, including support and voice coil loudspeaker voice coil, the support internal fixation has U iron, inside from up being fixed with magnet and china department down in proper order of U iron, be equipped with the clearance between U iron and magnet and the china department, the voice coil loudspeaker voice coil is fixed in aforementioned clearance through playing the ripples, the voice coil loudspeaker voice coil passes through the lead wire and links to each other with binding post on the support, still be fixed with the sound basin in the support of voice coil loudspeaker voice coil top, the sound basin encircles the voice coil loudspeaker voice coil setting and fixes with voice coil loudspeaker voice coil periphery side, the support of U iron below still is fixed with the sound source board. When the voice coil loudspeaker voice coil vibrates, produce sound pressure, sound pressure promotes sound source board synchronous vibration through producing synchronous pressure by the air flue in the middle of magnificent department, magnet and the U iron, and the frequency channel that the sound source board produced is the low frequency range to compensate the low frequency of speaker not enough.

Description

Increase speaker of low frequency channel
[ technical field ] A method for producing a semiconductor device
The utility model relates to a speaker technical field especially relates to an increase low frequency channel's speaker.
[ background of the invention ]
The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound.
In the present intelligentized main speech system, in order to fully embody the sound of an omnidirectional audio band, a loudspeaker has the problem that the tone of a low-frequency band is difficult to fully embody.
The utility model discloses it is not enough to solve prior art and research and propose.
[ Utility model ] content
The utility model aims at overcoming the shortcoming of above-mentioned prior art, provide an increase low frequency channel's speaker.
The utility model discloses can realize through following technical scheme:
the utility model discloses an increase low frequency channel's speaker, including support and voice coil loudspeaker voice coil, the support internal fixation has U iron, inside from up being fixed with magnet and china department down in proper order of U iron, be equipped with the clearance between U iron and magnet and the china department, the voice coil loudspeaker voice coil is fixed in aforementioned clearance through playing the ripples, the voice coil loudspeaker voice coil passes through the lead wire and links to each other with binding post on the support, still be fixed with the sound basin in the support of voice coil loudspeaker voice coil top, the sound basin encircles the voice coil loudspeaker voice coil setting and fixes with voice coil loudspeaker voice coil periphery side, the support of U iron below still is fixed with the sound source board. The support is a fixed frame of the loudspeaker, the washer, the magnet and the U iron form a magnetic circuit system of the loudspeaker, the voice coil, the cone and the sound source plate form a vibration system of the loudspeaker, after the wiring terminal is electrified, an electric signal enables a coil of the voice coil to generate current through the lead wire, the coil can be stressed in the direction vertical to a magnetic field to move, once the voice coil is stressed to move, the coil can cut magnetic lines in a gap, when the magnitude of external signal current changes, according to the left-hand rule of Buddha, the coil can be stressed to move along with the magnitude and the direction of the current to push the cone bonded with the voice coil to vibrate, air vibration is pushed to generate sound, and the sound wave is transmitted (music can be heard by people); the principle of energy conversion is as follows: the electric energy, the magnetic energy and the sound energy generate sound pressure when the voice coil vibrates, the sound pressure generates synchronous pressure through an air passage in the middle of the washer, the magnet and the U iron, the sound source plate is pushed to vibrate synchronously, and the frequency band generated by the sound source plate is a low frequency band so as to make up for the low frequency deficiency of the loudspeaker.
Compared with the prior art, the utility model has the advantages that:
when the voice coil loudspeaker voice coil vibrates, produce sound pressure, sound pressure promotes sound source board synchronous vibration through producing synchronous pressure by the air flue in the middle of magnificent department, magnet and the U iron, and the frequency channel that the sound source board produced is the low frequency range to compensate the low frequency of speaker not enough.
[ description of the drawings ]
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
FIG. 1 is an exploded view of the present invention;
fig. 2 is a cross-sectional view of the present invention;
in the figure: 1. a support; 2. a sound basin; 3. washer; 4. a magnet; 5. iron U; 6. a voice coil; 7. a wiring terminal; 8. silk thread; 9. a sound source plate;
[ detailed description ] embodiments
The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings:
as shown in fig. 1-2, the utility model discloses an increase speaker of low frequency channel, including support 1 and voice coil loudspeaker voice coil 6, 1 internal fixation of support has U iron 5, 5 internal portions from up being fixed with magnet 4 and china department 3 down in proper order of U iron, be equipped with the clearance between U iron 5 and magnet 4 and the china department 3, voice coil loudspeaker voice coil 6 is fixed in the clearance through the bullet ripples, voice coil loudspeaker voice coil 6 links to each other with binding post 7 on the support 1 through lead wire 8, still be fixed with sound basin 2 in the support 1 of voice coil loudspeaker voice coil 6 top, sound basin 2 encircles the setting of voice coil loudspeaker voice coil 6 and is fixed with the 6 periphery sides of voice coil loudspeaker voice coil, support 1 of U iron 5 below still is fixed with sound source board 9. The support 1 is a fixed frame of the loudspeaker, the washer 3, the magnet 4 and the U-shaped iron 5 form a magnetic circuit system of the loudspeaker, the voice coil 6, the cone 2 and the sound source plate 9 form a vibration system of the loudspeaker, after the wiring terminal 7 is electrified, an electric signal enables a coil of the voice coil 6 to generate current through the lead wire 8, the coil can be stressed in a direction perpendicular to a magnetic field to move, once the voice coil 6 is stressed to move, the coil can cut magnetic lines in gaps, when the magnitude of external signal current changes, according to the left-hand rule of Fleming, the coil can be stressed to move along with the magnitude and the direction of the current, the cone 2 bonded with the voice coil 6 is pushed to vibrate, air vibration is pushed, sound is generated, and sound waves are transmitted (music which can be heard by people); the principle of energy conversion is as follows: the electric energy, the magnetic energy and the sound energy generate sound pressure when the voice coil 6 vibrates, the sound pressure generates synchronous pressure through an air passage in the middle of the washer 3, the magnet 4 and the U-shaped iron 5, the sound source plate 9 is pushed to vibrate synchronously, and the frequency band generated by the sound source plate 9 is a low frequency band so as to make up for the low frequency deficiency of the loudspeaker.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many changes, modifications, substitutions and variations can be made to the embodiments without departing from the technical principles of the present invention, and these changes, modifications, substitutions and variations should also be regarded as the protection scope of the present invention.
