Abstract
The utility model discloses a loudspeaker system, which comprises a far-field loudspeaker, a near-field loudspeaker and a middle-far-field loudspeaker, wherein the far-field loudspeaker is fixed at the upper end, the near-field loudspeaker is fixed at the lower end and the middle-far-field loudspeaker is disposed between the far-field loudspeaker and the near-field loudspeaker. A direction angle of a horn of the far-field loudspeaker is respectively 35 degrees horizontally and 35 degrees vertically, a direction angle of a horn of the middle-far-field loudspeaker is respectively 60 degrees horizontally and 60 degrees vertically, and a direction angle of a horn of the near-field loudspeaker is respectively 80 degrees horizontally and 80 degrees vertically. The loudspeaker system has the advantages that the loudspeaker system consists of the far-field loudspeaker, the middle-far-field loudspeaker and the near-field loudspeaker which respectively cover far field, middle-far field and near field of audition area and respectively adopt a waveguide design of 35 degrees*35degrees/60degrees*60 degrees/80degrees*80degrees of direction angles, thereby guaranteeing uniformity degree of sound field.
Description
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 existing common engineering audio amplifier, the reverberation sound proportion is higher, and the speech articulation index can seriously descend.Because large and medium-sized theater public address distance, especially medium-high frequency sound attenuating in far field is more obvious, and is bigger to the tonequality influence.Existing engineering audio amplifier adopts the body structure design of non-coaxial, tends to bring the acoustic interference phenomenon between high and low sound, and the comb filtering phenomenon is very obvious, and is difficult to eliminate.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sound box system with even sound field.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of sound box system, the design of variable directional bugle audio amplifier, it is characterized in that it comprise the near field audio amplifier of the far field audio amplifier, the lower end that are fixed on the upper end and be in the far field audio amplifier and the near field audio amplifier between middle far field audio amplifier, it is 35 ° of 35 ° of horizontal directions and vertical direction that the bugle of described far field audio amplifier points to the angle, to point to the angle be that horizontal direction is 60 ° of 60 ° and vertical direction to the bugle of far field audio amplifier in described, and it is 80 ° of 80 ° of horizontal directions and vertical direction that the bugle of near field audio amplifier points to the angle.
Described far field audio amplifier or middle far field audio amplifier comprise first casing and baffle plate, half chests body and later half casing before described baffle plate is divided into first casing, the microphone device of described far field audio amplifier or middle far field audio amplifier comprises high pitch loudspeaker and woofer, high pitch loudspeaker is arranged in the preceding half chests body, woofer is arranged in the later half casing, the coaxial setting of described woofer and high pitch loudspeaker.
Described high pitch loudspeaker is provided with Horn, and described woofer is provided with the bass bugle, and described bass bugle and described Horn are positioned at described preceding half chests body, and described Horn is positioned at described bass bugle.
The microphone device of described near field audio amplifier is coaxial full frequency speaker, and described near field audio amplifier adopts the ladder type body structure.
The far field audio amplifier is hung on the audio amplifier of far field by chain in described, and described near field audio amplifier is hung on the audio amplifier of middle far field by chain.
Compared with prior art, advantage of the present utility model is that sound box system is made up of far field, middle far field and near field audio amplifier, cover the far field of listening area, middle far field and near field respectively, adopt to point to the angle respectively: 35 ° * 35 °/60 ° * 60 °/80 ° * 80 ° waveguide design has guaranteed the uniformity of sound field.
High pitch loudspeaker and the design of woofer coaxial structure, the acoustic interference phenomenon of having eliminated fully between the high bass has thoroughly been eliminated the comb filtering phenomenon, has also brought the constant directional property of audio amplifier, makes the structure of casing compact more simultaneously.
High pitch loudspeaker is provided with Horn, and described woofer is provided with the bass bugle, makes the transaudient better effects if of audio amplifier.
The microphone device of near field audio amplifier is coaxial full frequency speaker.The pre cap drift angle is 35 degree.
