Abstract
The present invention proposes a kind of multi-functional deafener that amplifies, it includes speakerphone mode and cancellation mode and the switching switch being operated pattern switching between public address module and noise reduction module and signal phase adjusting means, when entering speakerphone mode, after the described multi-functional deafener that amplifies obtains acoustical signal, keep the phase place of original signal through described signal phase adjusting means, amplified amplify；When entering cancellation mode, the described multi-functional deafener that amplifies obtains after acoustical signal, is adjusted to antiphase acoustical signal through described signal phase adjusting means, amplified carries out sound-deadening and noise-reducing.The multi-functional deafener that amplifies of the present invention, by internal signal phase adjusting means, the process of acoustical signal is carried out according to different mode of operations, or keep the amplification of former phase place to amplify, or be adjusted to antiphase acoustical signal and carry out noise-reduction, to amplify and silencing function will integrate, be particularly suitable for the occasion of the zonule such as office or family.
Description
Technical field
The present invention relates to the muffling device technical field that amplifies, particularly to a kind of multi-functional deafener that amplifies, be used for reducing
Noise and the multipurpose field that amplifies.
Background technology
The most also not having at present multi-purpose portable to amplify deafener, noise cancelling headphone the most on sale is essentially wear-type
Or In-Ear, user sensation has inconvenience more, and the people wearing this device just can enjoy noise reduction, and surrounding other people still
It is in noise.In many zonules occasion, such as office, family etc., it is desirable to be able to cover whole small region amplify or
Muffling device, allow in zonule all can be in noise reduction environment per capita；Or listen to music simultaneously.
Summary of the invention
For the demand in existing application, it is an object of the invention to provide a kind of multi-functional deafener that amplifies, it can be real
Show the noise reduction in full wafer zonule or amplify.
For realizing the purpose of the present invention, the multi-functional deafener that amplifies of the present invention include speakerphone mode and cancellation mode and
Between public address module and noise reduction module, it is operated switching switch and the signal phase adjusting means of pattern switching, works as entrance
During speakerphone mode, after the described multi-functional deafener that amplifies obtains acoustical signal, keep former through described signal phase adjusting means
The phase place of signal, amplified amplifies；When entering cancellation mode, the described multi-functional deafener that amplifies obtains acoustical signal
After, it is adjusted to antiphase acoustical signal through described signal phase adjusting means, amplified carries out sound-deadening and noise-reducing.
Preferably, described multi-functional amplify deafener obtain acoustical signal be by with its wired or wireless pickup being connected
Device carries out the acquisition of acoustical signal.
The multi-functional deafener that amplifies of the present invention, by internal signal phase adjusting means, according to different Working moulds
Formula carries out the process of acoustical signal, or keeps former phase place to amplify amplifying, or is adjusted to antiphase acoustical signal and carries out noise reduction
Noise reduction, will amplify and silencing function integrates, and be particularly suitable for the occasion of the zonule such as office or family.
Accompanying drawing explanation
By detailed description below in conjunction with the accompanying drawings, the aforesaid objects, features and advantages with other of the present invention will become
Obviously.Wherein:
Fig. 1 show the operation principle schematic diagram of the multi-functional deafener that amplifies of the present invention.
Detailed description of the invention
In conjunction with the operation principle schematic diagram of the multi-functional deafener that amplifies of the present invention shown in Fig. 1, an enforcement of the present invention
The multi-functional deafener that amplifies of example includes speakerphone mode and cancellation mode and carries out work between public address module and noise reduction module
The switching switch of operation mode switching and signal phase adjusting means, when entering speakerphone mode, the described multi-functional noise reduction that amplifies
Device obtains after acoustical signal, keeps the phase place of original signal through described signal phase adjusting means, amplified amplifies；When
When entering cancellation mode, after the described multi-functional deafener that amplifies obtains acoustical signal, adjust through described signal phase adjusting means
It is made into antiphase acoustical signal, amplified carries out sound-deadening and noise-reducing.
In the above-described embodiment, the described multi-functional deafener that amplifies obtains acoustical signal is by or nothing wired with it
The pick up that line connects carries out the acquisition of acoustical signal.
The multi-functional deafener that amplifies of the present invention is useful in the environment needing to amplify or abate the noise, by obtaining telecommunications
Number (such as music signal), such as obtains acoustical signal, through signal phase by wired or wireless connected pick up from environment
Position adjusting means, keeps or adjusts original acoustical signal phase place, if keep former phase place, amplified, reaches the mesh amplified
, as play music；It is adjusted to antiphase acoustical signal, uses signal amplification circuit and loudspeaker device can offset again ring after amplifying
Border noise.The multi-functional deafener that amplifies of the present invention can make portable tools, needs noise reduction in being positioned over small region
Place, can be widely used in the occasions such as enterprise, office, family.
The invention is not limited in described embodiment, those skilled in the art is in the spirit without departing from the present invention i.e. public affairs
In the range of opening, still can make some revise or change, therefore the scope of the present invention with claims limit in the range of
Accurate.
