Description

Multimedia loudspeaker box

Technical field

It the utility model is related to audio amplifier and intelligent broadcasting field, more particularly to a kind of multimedia loudspeaker box.

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 liquid crystal or plasm TV on the market, 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, to solve this problem, audio amplifier and power amplifier, but traditional detachable speaker box or power amplifier price can be bought It is high to cause installation also inconvenient, it is necessary to connect many wire rods.On the market there is also some TV loudspeaker boxes, but all it is only simple Active audio amplifier, structure design is not reasonable, and sound effect is not good enough.The applicant by testing for a long time, 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 plays intelligent sound box, Patent No. based on TV or HIFI, AV of projector applications 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 used simultaneously differs, and some cabinet for TV are high, and some cabinet for TV are then shorter, so exist There have been different audition impressions, for human ear to the sound of different frequency, hearing loudness is also different, such as：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 gradually weaken with the rise of frequency, drastically subtract in below 80HZ for bass frequency range (20HZ-160HZ) Weak, the steep rate of oblique line is larger, and for bass without specific directive property during propagation, high pitch is then different, and it is to have necessarily that it, which is propagated, Directionality, if so high pitch position set it is bad, hearing loudness and the spatial impression of 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 channel separation it is inadequate the defects of, played back for number voice, or even the situation of dulling occur.Therefore, the utility model Exactly develop in this context.
