Description

Acoustic arrangement system for zero-degree sound production of object size center

Technical Field

The utility model relates to an audio equipment especially relates to an acoustics arrangement system of zero degree sound production in object size center.

Background

Since one loudspeaker unit cannot well reproduce 20 Hz-20 KHz, a plurality of loudspeakers are adopted to jointly complete the sound frequency all the time, and the number of the loudspeakers is more than 2. More than 2 loudspeaker units suffer from various acoustic problems in reproduction, with the result that the sound is not ideal. Particularly, the frequency of high pitch, middle pitch, low pitch and ultrahigh pressure sound is dispersed, some products emit sound from low pitch below (or above), and other frequency domain generators are in the middle, so that the sound sources of all frequency bands of the products are unstable, and the listening and appreciation experience is poor. Accordingly, there is a need for improvements to conventional acoustic systems.

SUMMERY OF THE UTILITY MODEL

In view of the above, there is a need to provide an acoustic alignment system with zero-degree sound production at the center of the object size.

An acoustic arrangement system for zero-degree sound production of an object size center comprises a box body, a loudspeaker assembly and a control module, wherein the loudspeaker assembly comprises two bass loudspeakers, a middle-range loudspeaker, a high-range loudspeaker and a super-high-range loudspeaker; the bass loudspeaker, the middle-pitch loudspeaker, the high-pitch loudspeaker and the ultra-high-pitch loudspeaker face to the front position of the box body; two woofer installs in the both sides position of box, tweeter and well sound speaker are located between two woofers, super tweeter locates between tweeter and the well sound speaker, woofer, super tweeter, well sound speaker's central point puts and establishes on same straight line.

Further, the control module comprises a frequency divider.

Furthermore, a horn is connected to the sound outlet of the high pitch loudspeaker.

Furthermore, a plurality of independent volume spaces are arranged in the box body, and the woofer, the middle-pitch loudspeaker, the high-pitch loudspeaker and the ultrahigh-pitch loudspeaker are respectively and independently arranged in different volume spaces.

Furthermore, two channels are further arranged in the box body, one channel is communicated with the volume space corresponding to one woofer, the other channel is communicated with the volume space corresponding to the other woofer, two sound guide pipes are arranged on the front side face of the box body, and the two sound guide pipes are respectively communicated with the two channels.

Furthermore, the two sound guide tubes on the box body are arranged at the center of the size of the object.

The utility model discloses zero degree vocal acoustics arrangement system in object size center's beneficial effect lies in: by changing the conventional acoustic arrangement: the power frequency divider is matched to ensure that the distribution area of the coupled frequencies of the high pitch, the middle pitch, the low pitch and the ultrahigh pressure sound is constant. The physical vibration sound wave of the sounding body and the sound wave radiated again by the sounding body to the installation object are both in the central position of the object size, the sound coupling is good, the reduction degree is high, the listening feeling is harmonious and comfortable, the practicability is high, and the popularization significance is strong.

FIG. 1 is a schematic diagram of a zero degree acoustic alignment system for a center of an object size.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the utility model provides an acoustics arrangement system of zero degree sound production in object size center, it includes box 50, loudspeaker subassembly (not mark in the picture) and control module group, loudspeaker subassembly and control module group are all installed on box 50, loudspeaker subassembly and control module group are connected, and control module group control loudspeaker subassembly work.

The horn assembly includes two woofers 10, a midrange speaker 20, a tweeter 30, and a tweeter 40; the woofer 10, midrange speaker 20, tweeter 30 and tweeter 40 are all directed toward the front of the cabinet 50. Two woofers 10 are installed in the both sides position of box 50, tweeter 30 and middle sound speaker 20 are located between two woofers 10, super tweeter 40 is located between tweeter 30 and middle sound speaker 20, woofer 10, super tweeter 40, tweeter 30, the central point of middle sound speaker 20 are located and are established on the same straight line, in this embodiment, a bugle 31 is connected to the sound outlet position of tweeter 30, improves the directive property of sound.

The loudspeaker box comprises a box body 50, a plurality of independent volume spaces (not shown) are arranged in the box body 50, a woofer 10, a middle-pitch loudspeaker 20, a tweeter 30 and a super-pitch loudspeaker 40 are respectively and independently arranged in different volume spaces, the two woofers 10 are also respectively and independently arranged in different volume spaces, two channels (not shown) are further arranged in the box body 50, one channel is communicated with the volume space corresponding to the woofer 10, the other channel is communicated with the volume space corresponding to the other woofer 10, two sound guide pipes 60 are arranged on the front side surface of the box body 50, the two sound guide pipes 60 are respectively communicated with the two channels, and the two sound guide pipes 60 are arranged at the center position of the object size.
