Also referring to Fig. 1 to Fig. 5, now speaker provided by the invention is illustrated.The speaker, including shell 1, set
In the subwoofer 2 in shell 1, multiple loudspeaker 3 for being distributed on shell 1 and in shell 1 and for controlling bass annular in shape
The control unit of big gun 2 and multiple loudspeaker 3, subwoofer 2 have different playback directions from each loudspeaker 3.
When in use, subwoofer 2 and multiple loudspeaker 3 can play the sound of different frequency range to different directions respectively.
Specifically, multiple loudspeaker 3 are used to play the audio of at least two frequency points.
Original sound signal is divided into multiple frequencies using control unit compared with prior art by speaker provided by the invention
Section, then be used in combination by subwoofer 2 and multiple loudspeaker 3, can correspond to multiple frequency points of sound, make audio from low to high multiple
The sound of frequency point is as true to nature as possible to be restored, and accomplishes that lossless high-definition quality plays；Also, since loudspeaker 3 are annularly distributed,
Enable 360 degree of the audio played out to hear without dead angle, especially when disposed within, entire room, user can be full of
Lossless high-definition quality audio can be obtained in room any position, improves the music experience sense of user.
Specifically, loudspeaker 3 can be divided into multiple groups, and every group is respectively provided at least one loudspeaker 3, and the loudspeaker 3 in same group are broadcast
Put the audio of identical frequency point.
Specifically, each loudspeaker 3 play the audio of different frequent points respectively.
Further, on the circular distribution arrangement of loudspeaker 3, the frequency point of the corresponding audio of loudspeaker 3 again high to Low distribution, by
Low to high distribution or random distribution.
Further, also referring to Fig. 1 to Fig. 5, as a kind of specific embodiment of speaker provided by the invention, loudspeaker
3 axis for surrounding shell 1 are annularly uniformly distributed on shell 1.In order to rationally utilize space, manufacturing cost is reduced, can be incited somebody to action
Shell 1 is designed to column, and has an axis, is distributed loudspeaker 3 around the axis, can guarantee the playback direction of each loudspeaker 3
360 degree of range can be covered.
Specifically, loudspeaker 3 are respectively positioned on the same sagittal plane of shell 1.
Further, it is as a kind of specific embodiment of speaker provided by the invention to Fig. 5 referring to Figure 2 together
Guarantee that the audio of subwoofer 4, speaker further include driven disc 4, driven disc 4 is set to one end of shell 1 and with subwoofer 2 along shell
1 axis distribution.Driven disc 4 is an elastic component, a confined space is formed between shell 1 and driven disc 4, subwoofer 2 is set to
In the confined space, since subwoofer 2 can make air vibration when playback, driven disc 4 can be in the confined space
The fluctuation of air-flow and agitate, push air, make to vibrate in incoming human ear, keep bass audio outstanding.
