Abstract

The utility model discloses a loudspeaker system, which comprises a middle-low-frequency loudspeaker array and a high-frequency loudspeaker array, wherein the middle-low-frequency loudspeaker array is fixed at the lower end, and the high-frequency loudspeaker array is arranged at the upper end. The middle-low-frequency loudspeaker array and the high-frequency loudspeaker array are both arranged via a circular arc surface form, each middle-low-frequency loudspeaker is provided with a horn with high directional property, and each high-frequency loudspeaker is provided with a horn with high directional property. The loudspeaker system has the advantages that sound amplifying efficiency and voice articulation can be increased because the loudspeakers of the loudspeaker system utilize the horn type box design with high directional property and cover far, middle and near fields regionally.

Description

A kind of sound box system

Technical field

The utility model relates to a kind of stereo set, especially relates to a kind of sound box system.

Background technology

Combination audio is very extensive large-scale theater or open-air concert The field.Use the unreasonable structure of existing combination sound box, on-the-spot coverage is little, causes on-the-spot internal zone dividing territory and can't listen to sound clearly.Because remote public address sound attenuating is bigger,, can't hear the effect of primary sound than the audience of distant positions simultaneously especially at the alt composition.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of sound box system that improves public address efficient and speech articulation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of sound box system, it comprises the medium and low frequency speaker array that is fixed on the lower end and is positioned at the high frequency speaker array of upper end, it is characterized in that described medium and low frequency speaker array arranges in the arc surface mode, described high frequency speaker array is arranged in the arc surface mode, described in each woofer be provided with the bugle of strong directional property, described each high sound box with sound is provided with the bugle of strong directional property.

Described medium and low frequency speaker array comprises 9 middle woofers, described 9 middle woofers are arranged in three rows, three row modes, the vertical pre-drift angle of loud speaker of going up woofer among the row most is 0 degree, the vertical pre-drift angle of the loud speaker of middle row's woofer is 3～7 degree, and the vertical pre-drift angle of the loud speaker of minimum row's woofer is 15～25 degree.

Described high frequency speaker array comprises 12 high sound box with sound, the vertical pre-drift angle of loud speaker of going up the high sound box with sound of row most is 0 degree, the vertical pre-drift angle of the loud speaker of the high sound box with sound of second row is 2～4 degree, the vertical pre-drift angle of the loud speaker of the high sound box with sound of the 3rd row is 8～10 degree, and the vertical pre-drift angle of the loud speaker of the 4th high sound box with sound is 25～30 degree.

Each high pitch loudspeaker on vertical four high pitch loudspeakers of described high frequency speaker array all is provided with power amplifier and digital signal processor, and signal enters into described high pitch loudspeaker after by power amplifier and digital signal processor.

Each woofer of vertical three medium and low spectrum loudspeakers of described medium and low frequency speaker array all is provided with power amplifier and digital signal processor, and signal enters into described woofer after by power amplifier and digital signal processor.

Compared with prior art, the utility model has the advantages that audio amplifier adopts the bugle formula cabinet design of strong directional property, that the subregion covers is far away, in, the near field, can improve public address efficient and speech articulation.

The vertical pre-drift angle that a plurality of medium and low spectrum loudspeakers and high pitch loudspeaker are provided with has respectively covered the far field in whole zone respectively, and the acoustic interference between senior middle school's bass has been avoided in middle far field and near field simultaneously.

For connecing one road signal separately, every bugle drives, to compensate different sound field characteristics.Three road horizontal arrays then broadening the horizontal cone of coverage of system, make it to reach 90 °.
