Abstract
The utility model discloses an active extra bass stereo speaker box comprising a speaker box body and a wiring board mounted on the speaker box body, wherein a stereo speaker connected with the wiring board is mounted on the sound box body and comprises a bass unit; a subwoofer and a power amplifier connected with the subwoofer are mounted in the speaker box body; and the power amplifier is electrically connected with the wiring board. The active extra bass stereo speaker box realizes regulation and processing of an audio signal from a sound source inside the speaker box through the power amplifier and the subwoofer; the speaker box does not needs to be connected to an external power amplifier system, so that the speaker box itself is capable of generating sound outwards through the bass unit and thereby has bass effect; therefore, the loudspeaker effect and the integrated performance of the speaker box are greatly improved; and the structure is further advantageous to improving the integrated grade of the speaker box products.
Description
Technical field
The utility model relates to the speaker products technical field in the daily household articles, is a kind of active subwoofer stereo speaker specifically.
Background technology
At present,, arrange speaker products in the increasing furniture of people, make to view and admire to obtain better acoustical quality at Music Appreciation or video display along with living standard improves day by day.People are when music appreciating or films and television programs now, and the sound that often needs audio amplifier to send has the subwoofer effect.For this reason, people often must purchase power amplification system separately on the basis of common audio amplifier, through power amplification system audio signal is handled; Could make audio amplifier can emit the subwoofer effect; Otherwise conventional audio amplifier can only be accomplished the conventional effect of raising one's voice, and sound effect is flat dull; This is consistent with common loudspeaker product, can't make the performance of audio amplifier be further improved.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of and can produce the subwoofer effect voluntarily, loud-speaking effect is good and improve the active subwoofer stereo speaker of product overall performance greatly.
The goal of the invention of the utility model is achieved in that a kind of active subwoofer stereo speaker; It comprises the audio amplifier body and is installed in the terminal block on the audio amplifier body; The boombox that is connected with terminal block is installed on the audio amplifier body; Said boombox includes bass unit, it is characterized in that: subwoofer that matches with bass unit and the power amplifier that is connected with subwoofer are installed in the said audio amplifier body, and power amplifier is electrically connected with terminal block.
The described active subwoofer stereo speaker of the utility model, it is as the further refinement of technical scheme, and said boombox also comprises middle pitch unit and voice unit.
Specifically, the described active subwoofer stereo speaker of the utility model, its said subwoofer and power amplifier all are arranged on the bottom of audio amplifier body.
Simultaneously, above-mentioned active subwoofer stereo speaker, its said boombox is arranged on the audio amplifier upper part of body.
During this time, the described active subwoofer stereo speaker of the utility model is provided with phase-reversing tube in its said audio amplifier body.
Further, above-mentioned active subwoofer stereo speaker is provided with stiffener in its said audio amplifier body.
And, above-mentioned active subwoofer stereo speaker, the front end surface of its said audio amplifier body is provided with the decoration stereotype.
In addition, at the described active subwoofer stereo speaker of the utility model, it is in the concrete manufacture process of product, and the bottom surface of said audio amplifier body is provided with plumbous pin nail.
Even the utility model is that high bass combination sound box is compared with the high sound box with sound of list of the prior art or single woofer, has the following advantages:
The described active subwoofer stereo speaker of the utility model; The power amplifier that subwoofer is installed in its audio amplifier body and is connected with subwoofer; Power amplifier is electrically connected with terminal block; Make the sound signal of source of sound regulate processing in audio amplifier inside through power amplifier and subwoofer, this audio amplifier need not to connect power amplification system outward again, and then makes audio amplifier itself outwards to send through bass unit to have bass effect; Improved the good and overall performance of audio amplifier loud-speaking effect greatly, this structure also helps to improve the whole class of speaker products.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
According to shown in Figure 1; The described active subwoofer stereo speaker of present embodiment; It comprises audio amplifier body 1 and is installed in the terminal block 2 on the audio amplifier body 1 that the boombox that is connected with terminal block 2 is installed on the audio amplifier body 1, and said boombox includes bass unit 3; Subwoofer 4 that matches with bass unit 3 and the power amplifier 5 that is connected with subwoofer 4 are installed in the said audio amplifier body 1, and power amplifier 5 is electrically connected with terminal block 2.
During this time, the described active subwoofer stereo speaker of the utility model, it is as the further refinement of technical scheme, and said boombox also comprises middle pitch unit 6 and voice unit 7.Specifically, its said subwoofer 4 and power amplifier 5 all are arranged on the bottom of audio amplifier body 1, and its said boombox is arranged on the top of audio amplifier body 1.And, be provided with phase-reversing tube 8 in the described audio amplifier body 1 of this audio amplifier.
In addition, above-mentioned active subwoofer stereo speaker is provided with stiffener 9 in its said audio amplifier body 1, further reinforces the bulk strength of audio amplifier.And, above-mentioned active subwoofer stereo speaker, the front end surface of its said audio amplifier body 1 is provided with decorates stereotype 10, and in the concrete manufacture process of product, the bottom surface of said audio amplifier body 1 is provided with plumbous pin nail 11.
The described active subwoofer stereo speaker of the utility model; It makes the sound signal of source of sound regulate processing in audio amplifier inside through power amplifier 5 and subwoofer 4; This audio amplifier need not the outer power amplification system that connects again; And then make audio amplifier itself outwards to send bass effect through bass unit 3, and having improved the good and overall performance of audio amplifier loud-speaking effect greatly, this structure also helps to improve the whole class of speaker products.
