Abstract
The utility model provides an external loudspeaker box of a notebook computer, which is characterized in that the integral design that a left sound track loudspeaker, a right sound track loudspeaker and a power amplifier are intensively arranged in an L-shaped box body is adopted. A woofer loudspeaker works in an L-shaped box chamber and is internally provided with a flat labyrinth type pipeline. When the notebook computer is used on the loudspeaker box, the woofer loudspeaker sounds behind a screen of the notebook computer. The external loudspeaker box has the advantages that the wiring is simple, the use is convenient and simple, and the L-shaped box chamber leads low frequency to descend more compared with the traditional structure.
Description
Affiliated technical field
The utility model relates to a kind of notebook computer external speaker.Especially the structure of audio amplifier can obviously be improved the replay effect of low frequency.
Background technology
At present, the boombox of notebook computer is owing to be subjected to the restriction of steric requirements such as light in structure thinning, and acoustics is very undesirable.A lot of users use external speaker instead and attempt to improve its tonequality, but the convenience that uses is again a problem, and putting of audio amplifier will take many spaces, and line neither be very convenient.Carry for convenience, product mostly uses external small-bore loudspeaker acoustic enclosure at present, use the playback of the audio amplifier medium-high frequency part of small-bore loud speaker to be easy to solve, but the playback of low frequency is difficult to reach effect preferably again.
The utility model content
Loaded down with trivial details for the low frequency deficiency that overcomes existing portable little audio amplifier and line, the purpose of this novel practical is to design a easy to use, the external speaker that low frequency playback lower limit is low.
The technical scheme that its technical problem that solves the utility model adopts is:
The L type that adopts the left and right acoustic channels loud speaker to install concentratedly in a casing designs, and two medium and high pitch loudspeakers of left and right acoustic channels are installed in casing two Side respectively, and in order to produce the stereophonic field effect, closed structure is adopted in its inner box chamber.Two other woofer then is operated in the L molding box chamber of two internal communication, and one of them case chamber is the case chamber of fixedly woofer, and another is the case chamber of the placement labyrinth type pipeline of flat; The case chamber volume of placing the labyrinth type pipeline is greater than the fixing case chamber volume of woofer.The top, case chamber of labyrinth type pipeline is used to place notebook computer, utilizes low frequency to have the unconspicuous characteristics of directivity, and notebook computer is placed on when using above the audio amplifier, and woofer is at notebook computer screen back sounding.
The beneficial effects of the utility model are, because the case cell structure of L type has been adopted in audio amplifier case chamber, casing can be accomplished not only frivolous but also firm easily, the bass reflex pipeline adopts the labyrinth type design to help the low frequency dive lower, the labyrinth pipeline can be strengthened gear housing rigidity again simultaneously, the purpose of doing like this is to make wave radiation path, the loud speaker back side become very long, eliminate the interference to speaker cones after the cabinet wall reflection of loud speaker back side ripple, the low frequency definition of audio amplifier is improved, notebook computer is placed on top use simultaneously, has saved user's usage space.Also audio amplifier and notebook computer can be placed in the computer package together and be convenient for carrying.Notebook computer also can reduce audio amplifier owing to too gently be easy to generate the adverse effect of resonance because certain weight is arranged itself.
Below in conjunction with drawings and embodiments the utility model is further specified.

1. casings among the figure, 2. woofer, 3. medium and high pitch loudspeaker, 4.USB interface, 5. earphone jack, 6. power supply indicator, the 7. fixing case chamber of woofer, the case chamber of 8. placing the labyrinth type pipeline, 9. power amplifier plate, 10. minor separator for container, 11. long separator for containers, 12. audio amplifier intermediate section dividing plates.
Embodiment
In Fig. 1, woofer 2 and medium and high pitch loudspeaker 3 are installed concentratedly in a casing 1, and whole box body 1 is the L type, and medium and high pitch loudspeaker 3 is installed in both sides in order to produce stereophonic effect, and closed structure is adopted in its inner box chamber; 2 of two other woofers are operated in the L molding box chamber of internal communication.Built-in suitable power amplifier in the casing 1 can be connected with the USB interface of notebook computer by USB interface 4, obtains the required power supply of power amplifier from notebook computer, and power supply indicator 6 is in order to provide the power supply indication; Earphone jack 5 is that sound source signal is obtained in the earphone output that is used for connecting notebook computer.
In Fig. 2, fixedly the case chamber 7 of woofer 2 is communicated with the case chamber 8 of placing the labyrinth type pipeline, the volume of placing the case chamber 8 of labyrinth type pipeline is greater than the fixedly case chamber 7 of woofer 2, place the labyrinth type pipeline to guarantee enough spaces, be flat owing to place the case chamber 8 of labyrinth type pipeline, therefore the thickness of casing 1 can be done very thinly but can guarantee enough mechanical strengths, and the ABS plastic of 2 to 3 millimeters thickness just can satisfy.
In Fig. 3, when the power amplifier that adopts was 2.1 channel power amplifier schemes, minor separator for container 10 and long separator for container 11 constituted the labyrinth type pipeline together, and adopting is symmetrically distributed installs.Two woofers 2 are operated in the whole case chamber that is interconnected simultaneously; Two woofers 2 are connected with suitable 2.1 sound channel power amplifier plates 9 with medium and high pitch loudspeaker 3.
In Fig. 4, when the power amplifier that adopts was 2.0 channel power amplifier schemes, with audio amplifier intermediate section dividing plate 12 with the inner box chamber of two woofers 2 separately, woofer 2 was operated in respectively in separately the case chamber to prevent mutual interference.
Claims (3)
