Abstract
The utility model discloses a sound box, which comprises a box body, wherein the left side and the right side on the front surface of the box body are symmetrically provided with at least a main loudspeaker, the sound box is characterized in that: the left side and the right side of the front surface of the box body are also symmetrically provided with a bass loudspeaker and an inverted tube outlet. Since the main loudspeaker, a surround loudspeaker, the bass loudspeaker and the inverted tube are integrally arranged, so the sound box can be convenient to arrange, the wire distribution can be facilitated; and the main loudspeaker, the surround loudspeaker, the bass loudspeaker and the inverted tube are arranged on the front surface of the box body, the layout of the sound box is simple and attractive, and the sound box effect is good.
Description
Technical field
The utility model relates to a kind of audio amplifier, especially active audio amplifier.
Background technology
Existing audio amplifier all adopts combined casing, comprises main loudspeaker, circulating loudspeaker and woofer.Wherein main loudspeaker and circulating loudspeaker generally are symmetricly set on the front panel of casing in the same way, and the general independent case of joining of woofer, or are arranged on upside or the downside or the back side of casing.Woofer is joined case separately and is given and practically to connect and put and make troubles, and woofer is audio amplifier acoustical reproduction phase locating bias when side direction is placed on the bar shaped audio amplifier; Woofer (comprises down) dorsad on the bar shaped audio amplifier when placing that the audio amplifier acoustical reproduction intensity of arbitrarily downgrading reduces the bass effect reduction.
The utility model content
The utility model provides a kind of solution of the above problems, provides a kind of and connects and put conveniently, and the audio amplifier acoustical reproduction is mutually placed in the middle, the audio amplifier that acoustical reproduction is effective.
The technical scheme of the utility model provides a kind of audio amplifier, comprises casing, said casing
Be symmetrically set with at least one main loudspeaker on the front, it is characterized in that: said casing front also is symmetrically set with woofer and phase-reversing tube outlet.
Preferably, during said woofer and phase-reversing tube export with said casing axis and are
The heart is symmetricly set on the inboard of said main loudspeaker.
Preferably, said phase-reversing tube is L shaped, and an end is connected with its outlet, and an end is to casing
Extend in the centre position.
Preferably, also be symmetrically set with several circulating loudspeakers on the said casing.
Preferably, said circulating loudspeaker all is arranged on the front of said casing.
Preferably, said circulating loudspeaker is the center with said casing axis, is symmetrical set
The outside at said main loudspeaker.
The audio amplifier of the utility model is owing to main loudspeaker, circulating loudspeaker, woofer
Be beneficial to the phase-reversing tube integrated setting and put and connect up, and main loudspeaker, circulating loudspeaker, woofer and phase-reversing tube all be arranged on the front of casing, layout is succinctly attractive in appearance and speaker effect is good.
Description of drawings
Fig. 1 is the structural representation of the audio amplifier of the utility model.
Fig. 2 is the cutaway view of audio amplifier shown in Figure 1.
Embodiment
Embodiment in the face of the utility model is described in further detail down.
As shown in Figure 1, the audio amplifier of the utility model comprises the casing 10 of long strip type, and casing just
Face center line bilateral symmetry is provided with two main loudspeakers 12.The inboard that the casing front is positioned at main loudspeaker 12 is symmetrically arranged with woofer 14 and phase-reversing tube outlet 16.As shown in Figure 2, phase-reversing tube 17 is L shaped, and an end is connected with its outlet 16, and an end extends the acoustical reproduction phase accurate positioning that makes audio amplifier to the casing centre position.The outside of main loudspeaker 12 is symmetrically set with a circulating loudspeaker 18.The opening of main loudspeaker 12, woofer 14, phase-reversing tube and circulating loudspeaker 18 all are arranged on the front of casing 10, at utmost bring into play the speaker playback acoustic intensity.
Above embodiment is merely the utility model a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
