Abstract
The utility model relates to an audio engineering field, concretely relates to anti -interference speaker, fix including top flat, skeleton, voice coil loudspeaker voice coil, magnet, U iron, voice coil loudspeaker voice coil on the skeleton, the magnet is located the top flat with between the U iron, U iron and frame connection, the voice coil loudspeaker voice coil outside still is equipped with the anti -interference magnetosphere of round, and anti -interference magnetosphere sets up in the U iron outside, includes still that the device of making an uproar falls in the self -adaptation, and the self -adaptation is fallen the device of making an uproar and is included piezoceramics, switch, electronic potentiometer, and piezoceramics, switch and electronic potentiometer connect in proper order. The utility model discloses the structural piezoceramics's of utilization acoustic -electric transducing converts the volume that electric signal control electronic potentiometer comes the control loudspeaker into to noise on every side, adopting the design of interpole coil, at speaker during operation interpole coil electromagnetic field that produces and the electromagnetic field interact that the loudspeaker voice coil produced, having resisted the mutual electromagnetic interference between surrounding environment and the speaker, make the speaker during operation noiseless, the SNR is high, makes the voice signal strong, and resolution ratio is high.
Description
Technical field
The utility model belongs to electroacoustic techniques field, is specifically related to a kind of anti-interference loud speaker.
Background technology
Loud speaker in earphone can convert the electrical signal to acoustical signal and be radiated the electroacoustic transducer gone in air.Traditional loud speaker is divided into electrodynamic type, electromagnetic type, electrostatic, piezoelectric type, ionic formula and pneumatic type etc. by operation principle.In the loud speaker of each type, using is dynamic speaker at most, the most widely, is also called coil-moving speaker.Due to the existence of the voice coil loudspeaker voice coil of dynamic speaker, be inevitably subject to the interference of electromagnetic radiation around.In general use occasion, this interference is also unlikely to the normal hearing having influence on people.But under the environment for use that some is special, as hearing aids loud speaker, this interference may have influence on the normal hearing of people.Traditional earphone speaker has in fish use procedure the situation that ambient noise is larger that often occurs, needs oneself adjustment volume artificial, very inconvenient.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of anti-interference loud speaker, overcomes the deficiencies in the prior art, reasonable in design, compact conformation, loud speaker back side acoustical cotton be provided with the fidelity being beneficial to sound, adsorbed some loud speakers and rocked or noise in vibrations process; Adopt the design of interpole coil, the electromagnetic field that interpole coil produces when speaker operation and the electromagnetic field mutual induction that loudspeaker voice coil produces, resist the mutual electromagnetic interference between surrounding environment and loud speaker, there is adaptive noise reduction device in housing increase simultaneously, improve loud speaker interference free performance further.
The technical program content is as follows:
A kind of anti-interference loud speaker, comprise top flat, skeleton, voice coil loudspeaker voice coil, magnet and U iron, described voice coil loudspeaker voice coil is fixed on described skeleton, described magnet is between described top flat and described U iron, described U iron is connected with described skeleton, the anti-interference magnetosphere of a circle is also provided with outside described voice coil loudspeaker voice coil, described anti-interference magnetosphere is arranged at outside described U iron, also comprise adaptive noise reduction device, described adaptive noise reduction device comprises piezoelectric ceramic, switch, electronic potentiometer, and described piezoelectric ceramic, switch and described electronic potentiometer are linked in sequence.
Preferably, described anti-interference loud speaker upper surface is provided with one deck waterproof ventilative layer.
Preferably, described anti-interference loud speaker dorsal part is also provided with one deck acoustical cotton.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model provides a kind of anti-interference loud speaker, structure utilizes the noise of acoustic-electric transducing to surrounding of piezoelectric ceramic be converted to the signal of telecommunication and control the volume that electronic potentiometer carrys out control loudspeaker, thus realize the self-adapting volume control of earphone, make earphone under different noisy environments, not need manual operation namely can realize volume and regulate; Setting up of switch facilitates translating self-adapting or general mode at any time, adds the hommization in earphone use; Loud speaker back side acoustical cotton be provided with the fidelity being beneficial to sound, adsorbed some loud speakers and rocked or noise in vibrations process; Adopt the design of interpole coil, the electromagnetic field that interpole coil produces when speaker operation and the electromagnetic field mutual induction that loudspeaker voice coil produces, resist the mutual electromagnetic interference between surrounding environment and loud speaker, noiseless when making speaker operation, signal to noise ratio is high, make voice signal strong, resolution is high.
