A 0.1 ultra low sound pod is added on the basis of the 2.0.1 multimedia sound box, and two 0.1 ultra low sound pods and the left and right channels of the 2.0 stereo sound box are installed on a box body to from a left channel and a right channel which are respectively provided with a 0.1 ultra low sound box, and now, a 2.0.2 structural style stereo sound multimedia sound box is achieved.
Description
Affiliated technical field
The utility model relates to a kind of multimedia loudspeaker box product, especially broadband multi-mode high-fidelity multimedia loudspeaker box.
Background technology
Present known multimedia loudspeaker box is divided into two classes:
1, two channel stereo active audio amplifiers, two audio amplifiers and two passage power amplifiers by left and right acoustic channels are formed, be commonly called as 2.0 audio amplifiers, wherein the implication of " active " is that power amplifier is installed in audio amplifier inside (following identical), if its power amplifier then is called the 2.0+1 audio amplifier for standalone chassis designs, more than be referred to as 2.0 stereo speaker systems;
2, the stereo active audio amplifier of triple channel (Fig. 2), by woofer 14, about two satellite casees 12,13 and triple channel power amplifier form, be commonly called as 2.1 audio amplifiers, if its power amplifier then is called the 2.1+1 audio amplifier for standalone chassis designs, wherein: woofer 14 is commonly called as subwoofer, its frequency range only accounts for 1% of audio range, is become X.1;
More than known 2.0 and 2.1 multimedia loudspeaker boxes all exist the imperfection part: at first the frequency band range of 2.0 audio amplifiers can be contained high pitch, middle pitch and bass, but bass dynamics and dive are not enough, and the sound that sounds is shrivelled unable; Secondly the frequency band range of 2.1 audio amplifiers can be contained high pitch, middle pitch and bass, though bass has had certain dynamics, frequency band range of two satellite casees can only be contained high pitch and middle pitch about it, and these two audio amplifiers can not use separately as 2.0 audio amplifiers;
Summary of the invention
For the bass satellite case not enough and 2.1 multimedia loudspeaker boxes that overcomes known 2.0 multimedia loudspeaker boxes can not be as the defective of 2.0 audio amplifiers use, the utility model provides a kind of 2.0.1 multimedia loudspeaker box, this multimedia loudspeaker box can extend to ultra-low frequency 0.1 subwoofer big gun and carries out organic assembling (combination back abbreviation 2.0.1 audio amplifier) with one by a cover 2.0 audio amplifiers, can not only be used as the use of 2.0 audio amplifiers and also can be used as the use of 2.1 audio amplifiers, and overcome the above-mentioned shortcoming of known 2.0 audio amplifiers and 2.1 audio amplifiers.Among Fig. 6, on the basis of 2.0.1 multimedia loudspeaker box, increase by one 0.1 subwoofer big gun and one road subwoofer power amplifier again, 2.0 stereo left and right sides passage (1), (2) are installed in the body structure with two 0.1 subwoofer (3) respectively, thereby are embodied as the multimedia loudspeaker box of 2.0.2 version.
The technical scheme that its technical problem that solves the utility model adopts is:
Fig. 3, in the 2.0.1 sound box system, form by the triple channel playback system, wherein two passages are 2.0 stereo left channel audio amplifiers (1) and 2.0 stereo R channel audio amplifiers (2), the two is collectively referred to as 2.0 stereo speakers, connect 2.0 stereo left channel power amplifiers (4) and 2.0 stereo R channel power amplifiers (5) respectively, the two is collectively referred to as stereo amplifier, forms 2.0 stereo speaker systems.Its frequency range is operated in the scope of high pitch, middle pitch and bass; Third channel is that 0.1 subwoofer power amplifier (6) connects 0.1 subwoofer audio amplifier (3), connects the back and is called for short 0.1 subwoofer big gun, and its operating frequency range is in bass and subsonic scope.
When working simultaneously, three passages in the 2.0.1 sound box system then can form the wideband multimedia audio system of playing high pitch, middle pitch, bass and subwoofer four band frequencies.When the sound volume control device (7) that is provided with on the triple channel power amplifier was turned off 0.1 subwoofer audio amplifier passage, the 2.0.1 sound box system then can be operated in 2.0 stereo speaker system modes and can play the gamut music that has bass.The sound volume control device (7) of regulating 0.1 subwoofer big gun then can compensate control to the bass size of 2.0 stereo speaker systems.
Among Fig. 6, on the basis of 2.0.1 multimedia loudspeaker box, increase by one 0.1 subwoofer big gun again, the left and right sides passage of two 0.1 subwoofer big guns (3) and 2.0 stereo speakers (1), (2) is installed in and forms left and right sides passage on the casing and all have 0.1 subwoofer audio amplifier separately, promptly forms the stereo multimedia loudspeaker box of 2.0.2 version this moment.
The beneficial effects of the utility model are, the 2.0.1 audio amplifier both can be used as 2.0 audio amplifiers and used and also can be used as 2.1 audio amplifiers and use, and when two states can both be play the broadband music signal, the also fairly simple cost of structure was low.
