Description

A kind of loud speaker
Technical field
The utility model relates to a kind of loud speaker.
Background technology
Along with the expansion in consumer electronics market, the consumer electronics products such as a large amount of mobile phone, notebook computer are used widely, and as acoustic element important in consumer electronics product, loud speaker has demand widely.
Loud speaker, comprising: auxiliary system, comprises protecgulum and shell; Magnetic circuit system, comprise the washer and magnet that combine from top to bottom, magnetic circuit system is provided with magnetic gap; Vibrational system, the voice coil loudspeaker voice coil comprising vibrating diaphragm and combine with vibrating diaphragm, voice coil loudspeaker voice coil is arranged in magnetic gap; The curent change be arranged in the voice coil loudspeaker voice coil in magnetic gap makes the magnetic field force induced effect of voice coil loudspeaker voice coil produce vibration, drives diaphragm oscillations sounding.But in prior art, loud speaker also comes with some shortcomings:
1, the decibel of sound that sends of loud speaker is inconsistent, and especially when listening to the music, different song, the volume that loud speaker sends is different, uses inconvenience.
2, loud speaker is easily intake and damages.
Utility model content
For the problems referred to above, the utility model provides a kind of loud speaker, uses convenient.
In order to solve the problem, the technical scheme that the utility model provides is:
A kind of loud speaker, comprise voice coil loudspeaker voice coil, vibrating diaphragm, shell, also comprise sound transducer, check processing module, power regulation module, described check processing module is connected with described sound transducer, power regulation module signal, and described power regulation module is electrically connected with external power source, described voice coil loudspeaker voice coil.
Sound transducer is utilized to detect volume around, when detect the sound sent of loud speaker excessive or too small time, check processing module changes electric current, the voltage swing in voice coil loudspeaker voice coil by power regulation module, thus the sound sent of adjustment loud speaker, make it to recover normal volume.
Preferably, described shell is provided with waterproof net.
Preferably, described shell is provided with air-vent, and described waterproof net covers on described air-vent; Air-vent exchanges by the air in shell and extraneous gas, ensures that tonequality is normal, undistorted.
Preferably, described check processing module is connected with external host signal; Be convenient to control volume flexibly.
Preferably, described shell is provided with illuminating lamp.
Preferably, also heat abstractor is provided with in described shell; During long-time use, the temperature in shell is too high, utilizes heat abstractor to lower the temperature.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by increasing sound transducer, check processing module, power regulation module, the volume that can effectively keep loud speaker to send is constant, the phenomenon that sound is too small or excessive can not be there is, increase illuminating lamp, heat abstractor, add the function of illumination, heat radiation, allow loud speaker use convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, voice coil loudspeaker voice coil, 2, vibrating diaphragm, 3, shell, 4, sound transducer, 5, check processing module, 6, power regulation module, 7, waterproof net, 8, air-vent, 9, illuminating lamp, 10, heat abstractor.
Embodiment
Below the utility model is described further:
Composition graphs 1: a kind of loud speaker, comprise voice coil loudspeaker voice coil 1, vibrating diaphragm 2, shell 3, sound transducer 4, check processing module 5, power regulation module 6, check processing module 5 is connected with sound transducer 4, power regulation module 6 signal, and power regulation module 6 is electrically connected with external power source, voice coil loudspeaker voice coil 1.
Sound transducer 4 is utilized to detect volume around, when the sound sent of detection 4 loud speaker excessive or too small time, check processing module 5 changes electric current, voltage swing in voice coil loudspeaker voice coil 1 by power regulation module 6, thus the sound sent of adjustment loud speaker, make it to recover normal volume.
Shell 3 is provided with waterproof net 7.
Shell 3 is provided with air-vent 8, and waterproof net 7 covers on air-vent 8; Air-vent 8 allows the air in shell 1 exchange with extraneous gas, ensures that tonequality is normal, undistorted.
Check processing module 5 is connected with external host signal; Be convenient to control volume flexibly.
Shell 3 is provided with illuminating lamp 9.
Heat abstractor 10 is also provided with in shell 3; During long-time use, the temperature in shell is too high, utilizes heat abstractor to lower the temperature.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
