Also referring to Fig. 1 to Fig. 5, now speaker provided by the utility model is illustrated.The speaker, including shell 1, the subwoofer 2 in shell 1, the annular in shape multiple loudspeaker 3 being distributed on shell 1 and in shell 1 and respectively with it is low The control unit that sound big gun 2 and multiple loudspeaker 3 connect, the outlet sound mouth of subwoofer 2 have different courts from the outlet sound mouth of each loudspeaker 3 To.

When in use, subwoofer 2 and multiple loudspeaker 3 can play the sound of different frequency range to different directions respectively. The direction of the outlet sound mouth of subwoofer 2 and loudspeaker 3 is consistent with respective playback direction.

Specifically, multiple loudspeaker 3 are used to play the audio of at least two frequency points.

Original sound signal is divided into more by speaker provided by the utility model using control unit compared with prior art A frequency range, 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 The sound of multiple frequency points is as true to nature as possible to be restored, and accomplishes that lossless high-definition quality plays；Also, since loudspeaker 3 are annular in shape Distribution so that the audio played out can 360 degree heard without dead angle, especially when disposed within, entire room can be full of, User can obtain lossless high-definition quality audio in room any position, improve the music experience sense of user.

Specifically, loudspeaker 3 can be divided into multigroup, 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 respectively play the audio of different frequent points.

Further, on the circular distribution arrangement of loudspeaker 3, the frequency point of 3 corresponding audio of loudspeaker again high to Low distribution, by Low to high distribution or random distribution.

Further, also referring to Fig. 1 to Fig. 5, a kind of specific embodiment party as speaker provided by the utility model Formula, loudspeaker 3 are annularly uniformly distributed in around the axis of shell 1 on shell 1.In order to rationally using space, reduce manufacturing cost, Shell 1 can be designed to column, and there is an axis, so that loudspeaker 3 is distributed around the axis, can guarantee the playback of each loudspeaker 3 Direction can cover 360 degree of range.

Specifically, loudspeaker 3 are respectively positioned on the same sagittal plane of shell 1.

Further, also referring to Fig. 2 to Fig. 5, a kind of specific embodiment party as speaker provided by the utility model Formula, in order to ensure the audio of subwoofer 4, speaker further includes driven disc 4, driven disc 4 be set to one end of shell 1 and with subwoofer 2 Axis along shell 1 is distributed.Driven disc 4 is an elastic component, and a confined space, subwoofer are formed between shell 1 and driven disc 4 2 are set in the confined space, since subwoofer 2 can make air vibration, driven disc 4 can be with the confined air when playback Between interior air-flow fluctuation and agitate, push air, make vibration be passed to human ear in, keep bass audio outstanding.

Specifically, Fig. 2 to Fig. 5 is please referred to, as a kind of specific implementation mode of speaker provided by the utility model, passively Disk 4 includes that elastic disk body 401 and the disk body mounting ring 402 set on 401 periphery of elastic disk body, driven disc 4 are pacified entirely through disk body Dress ring 402 is connect with shell 1.Elastic disk body 401 is the component agitated, disk body mounting ring 402 then can easily by by Moving plate 4 is fixed on shell 1, improves installation effectiveness and structural stability.

Further, refering to fig. 1 to Fig. 5, as a kind of specific implementation mode of speaker provided by the utility model, in order to So that audio is full of entire room as far as possible, while making rationally outstanding low to obtain using the space inside shell 1 The angle all same of the direction of the outlet sound mouth of sound audio, the direction of the outlet sound mouth of subwoofer 2 and each loudspeaker 3.

Specifically, refering to fig. 1 to Fig. 5, as a kind of specific implementation mode of speaker provided by the utility model, subwoofer 2 playback direction and the playback direction of loudspeaker 3 are at right angles arranged.4 playback direction of subwoofer in figure is downward, the playback of loudspeaker 3 Direction radially outward, ensures that speaker can make 360 degree of diffusions of sound in multiple positions, while making setting for shell 1 along shell 1 Meter manufacture is simpler, reduces production cost；The inner space of shell 1 can be further compressed, and pass through smaller space The bass effect that high-quality can be obtained is conducive to the Miniaturization Design of speaker.

Further, 1 is please referred to Fig.1, as a kind of specific implementation mode of speaker provided by the utility model, control is single Member includes the frequency division module 5 being connect respectively with subwoofer 2 and multiple loudspeaker 3 and the wireless communication module being connect with frequency division module 5 6。
