Description
Technical field
Field, the multimedia intelligent more particularly to based on TV or projector applications are played the present invention relates to audio amplifier and intelligence
Audio amplifier.
Background technology
At present, traditional vacuum tube television receiver is eliminated substantially, and manufacturer also already stops production such machine.It is main former
Because be this television set drawback the more, such as bulky, weight is big, and heating is severe, and power consumption is high, resolution ratio also relative mistake.Mesh
Preceding is all on the market liquid crystal or plasm TV, and the family also having certainly is to use optical projection system.For liquid crystal or plasma electric
Depending on for, they belong to flat type, for relatively conventional vacuum tube television receiver liquid crystal or plasma be advantage the more, but
Still have a problem that, that is, flat panel TV playback sound is thin, and main cause can not be used in very thin space
Larger loudspeaker unit, will solve this problem, can buy audio amplifier and power amplifier, but traditional detachable speaker box or power amplifier price
It is high to cause installation also inconvenient, it is necessary to connect many wire rods.Some TV loudspeaker boxes are there is also on the market, but are all only simple
Active audio amplifier, structure design is not reasonable, and sound effect is not good enough.The applicant is tested by prolonged, by casing
The installation of structure and circuit board has obtained ideal using effect, on 06 06th, 2016 to country through having gone optimization
Department of Intellectual Property has submitted a entitled HIFI, AV based on TV or projector applications and has played intelligent sound box, Patent No.
201620541276.5, the patent application is authorized, but during use, the application has found a problem, that is,
For different families, the cabinet for TV for using simultaneously is differed, and some cabinet for TV are higher, and some cabinet for TV are then shorter, so exist
Different auditions impressions are occurred as soon as, to the sound of different frequency, hearing loudness is also different, for example for human ear:Human ear is to sound intermediate frequency
The sound intensity that section (150HZ-2500HZ) is experienced is larger and flatter, and high pitch frequency range (2500HZ-20000HZ) is experienced
To sound intensity then as the rising of frequency gradually weakens, drastically subtract in below 80HZ for bass frequency range (20HZ-160HZ)
Weak, the steep rate of oblique line is larger, and bass is without specific directive property during propagation, and high pitch is then different, and it is have necessarily that it is propagated
Directionality, if so high pitch position set it is bad, the spatial impression of hearing loudness and sound can be influenceed, can so make sound
The playback effect of sound is had a greatly reduced quality;Meanwhile, in order to consider small product size, the left and right acoustic channels interval of existing product is small, thus makes
Into the defect that channel separation is inadequate, for number voice playback, or even the situation that dulling occurs.Therefore, the present invention is exactly
Develop in this context.
The content of the invention
The invention aims to solve above-mentioned technical problem, there is provided a kind of many based on TV or projector applications
