Abstract
A solid audio transmitter comprises a magnet and a voice coil and is characterized in that upper neodymium iron boron and lower neodymium iron boron are arranged on the top portion of an outer casing,a soft iron is sandwiched between the upper neodymium iron boron and the lower neodymium iron boron, pole pieces are arranged among the inner wall of the outer casing, the upper neodymium iron boron,the lower neodymium iron boron and the soft iron, the voice coil is mounted in the pole pieces, and an elastic plate is arranged below the voice coil and fixedly connected with an audio frequency vibrator. The conventional loudspeaker can achieve another audio transmission function after being transformed, a mode of utilizing a cone to push air to sound is replaced by a mode of utilizing the coneto push solid media to sound, and phase distortion of sound transmission can be small, thereby resolving the problem of directive property of the loudspeaker. Besides, magnetic steel of the common loudspeaker is replaced by high-performance neodymium iron boron materials to increase excitation filed, thereby increasing magnetic field strength. Further, close combination of the voice coil and therigid elastic plate is favorable for effective output of a transmission device. The solid audio transmitter can effectively amplify amplitude of vibration, increases low-frequency effect, reduces manufacturing cost, is simple in structure and can be processed into any specification.
Description
Technical field
The utility model belongs to the electroacoustic audio area, relates to a kind of device of audio transmission function, particularly a kind of electromagnetic energy is converted to the solid audio transmitter that mechanical energy (vibration) passes to the sounding medium by transmitting device.
Background technology
The tradition loudspeaker are to utilize voice coil loudspeaker voice coil vibrations cone to promote the air sounding, sound with the vibration of piston type point sound source, have that directive property is sharp-pointed, the weak link of transient response difference.
Summary of the invention
Technical problem to be solved in the utility model overcome exactly because of the magnetostrictive material amplitude little, the defective of the low-frequency effects difference of audio transmission device, utilize voice coil loudspeaker voice coil and shell fragment to amplify amplitude, by audio transmission device transmission sound, increase low-frequency effect, the deficiency of low-and high-frequency difference in remedying and a kind of solid audio transmitter of inventing.
The utility model solves its technical problem by following technical proposals:
A kind of solid audio transmitter comprises magnet and voice coil loudspeaker voice coil, it is characterized in that: neodymium iron boron is up and down arranged at the top in the shell; Accompanying soft iron between the neodymium iron boron up and down; Outer casing inner wall and be pole shoe between neodymium iron boron and the soft iron up and down; Voice coil loudspeaker voice coil is installed in the middle of pole shoe; Voice coil loudspeaker voice coil divide into a shell fragment, shell fragment and audio frequency shaking device are connected and fixed.
Described voice coil loudspeaker voice coil and shell fragment are that the voice coil loudspeaker voice coil of traditional loudspeaker closely is connected with shell fragment, and it is fixing to exert pressure.
The utility model utilizes traditional loudspeaker to transform, make it reach another kind of audio transmission function, no longer utilize cone to promote the air sounding, but promote the solid dielectric sounding, like this, the phase distortion meeting of sound transmission is very little, 180 ° of plane tunes of solid dielectric sounding directive property, fully solved the problem of loudspeaker directive property, the magnet steel of common loudspeaker is replaced to high performance Nd-Fe-B magnetic pole material increases excitation field, improves magnetic field intensity; Voice coil loudspeaker voice coil and rigidity shell fragment are combined closely and are helped transmitting device effectively to export, the elasticity of rigidity shell fragment will suit in integrally-built anharmonic ratio, input audio signal, voice coil loudspeaker voice coil promptly produce vibration under the excitation field effect, this mechanical movement promotes transmitting device by the rigidity shell fragment and passes to the sounding medium.The utility model can amplify Oscillation Amplitude effectively, increases low-frequency effect, reduces cost of manufacture, and production technique structure is simple, can manufacture any specification.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the present invention is further elaborated.
A kind of solid audio transmitter, its shell 1 internal upper part are neodymium iron borons 2,4 up and down, and the centre accompanies soft iron 3; Outer casing inner wall and middle neodymium iron boron up and down 2,4, the gap between the soft iron 3 are pole shoe; Voice coil loudspeaker voice coil 6 is installed in pole shoe; Shell fragment 7 is equipped with in the lower end of voice coil loudspeaker voice coil 6; Shell fragment 7 is fixing with voice frequency vibrating device 9
Shell fragment 7 is by spring steel, aluminum titanium alloy, little, the on-deformable material of good, the tired mechanism of carbon fiber class rigidity.
The utility model is to utilize traditional loudspeaker to remove cone, bullet ripple, keeps magnet, soft magnet and voice coil loudspeaker voice coil; It is fixing that voice coil loudspeaker voice coil 5 and shell fragment 7 are combined closely and exerted pressure, and voice frequency vibrating device 9 is equipped with in the lower end of shell fragment 7.Voice coil loudspeaker voice coil 5 produces the audio frequency vibrations when input electrical signal, and voice frequency vibrating device 9 passes to the hard solid medium with audio signal, makes the solid dielectric sounding.So just remedied that magnetostrictive material audio transmission device amplitude is little, the defective of low frequency differences.
