Description
Technical field
The utility model is related to noise reduction field, and in particular to a kind of portable multi-function Intelligent noise reduction device.
Background technology
Real-life noise reduction technology mainly has two kinds, and a kind of is to shake the noise produced to object to carry out noise reduction, is led to
Sound insulation by filling material (such as glass fibre Sound-proof material) or use enhancing environment tightness in wall is crossed (for example to connect in door and window
At seam using sealing joint strip etc.) completely cut off noise；The above method is larger due to quantities, and can only be beyond isolated environment space
Noise in noise, space still can not be controlled and manage (to be produced such as in confined space by people or electric equipment
Noise)；Another is to carry out noise reduction by wearing acoustic insulating ear plug or active noise cancelling headphone, and above-mentioned method fails to realize pipe
The noise transmission in the ranged space is managed, and individual wears the problems such as ear distending pain, tympanitis occur in earplug overlong time.Together
When, in a space, noise source is broadly divided into two classes, and a class is to come from outside, and a class comes from interior volume, existing
Noise reduction product can only passively completely cut off interior volume, external noise, it is impossible to realize that the active to noise is eliminated, and can not be according to noise
Intensity Intelligent noise reduction.
The content of the invention
The utility model purpose is to provide a kind of portable multi-function Intelligent noise reduction device, to solve the above problems.
Its concrete technical scheme is as follows：
A kind of portable multi-function Intelligent noise reduction device, including shell and the circuit board in shell, circuit board are set
It is equipped with lithium battery, case body and is provided with power switch；It is characterized in that：Microcontroller is provided with the circuit board, is raised
Sound device, vibrations generator, shock sensor, USB Bluetooth musics module, sound pick-up, described shock sensor, USB bluetooth sounds
Happy module, sound pick-up are respectively used to obtain external shock signal, audio signal and the road signal of noise signal three, the vibration signal
After signal amplification circuit and phase inverter, the audio signal after signal amplification circuit and volume control module, it is described
Noise signal is after signal amplification circuit and phase inverter, and three road signal Dietary behavior switching circuits, the mode switching circuit exists
One is selected under microprocessor control to three road signals of input to export, the signal of output leads to after digital power amplifier
The relay for crossing microprocessor control enters loudspeaker or vibrations generator.
Further, the signal that described sound pick-up and USB Bluetooth musics module are obtained passes through microcontroller after processing
The relay of control is input to loudspeaker；The signal that described shock sensor is obtained passes through microprocessor control after processing
Relay be input to vibrations generator.
Further, the mode switching circuit is MUX.
Further, described shell upper is trapezoidal, and center upper portion is provided with speaker openings；The sound pick-up is two
Individual, shell upper both sides are each provided with a sound pick-up opening, and power switch is arranged at the side of shell upper.
Further, described outer casing underpart is plane, is easy to place.
Further, the outer casing underpart is additionally provided with the fixation adhesive plaster of TPE materials, is easy to fix during installation.
The utility model has the advantage of：According to the propagation principle of sound wave, by producing reverse shock wave to reach suppression
The effect of noise transmission., can be by the way that the denoiser be fixed on noise transmission medium, such as when noise comes from outside
On window-glass, when ambient noise is incoming, glass is caused to shake, the shock sensor of denoiser perceives vibration signal and gathers anti-
Xiang Hou, produces opposite in phase, an equal-sized vibration signal, for offsetting the external world by microprocessor control vibrations generator
Noise；Give same reason, during for indoor noise reduction, in real time collection noise signal and produce opposite in phase, it is equal-sized
Voice signal, and sent through loudspeaker, for offset noise.USB Bluetooth music modules are additionally provided with, for receiving outside music
Play signal, and broadcasted through loudspeaker.
