Abstract

Disclosed is an audio regulating unit which is composed of a framework 1 and more than one pair of grid strips 2, wherein the framework 1 is square, each grid strip 2 is equipped with a groove 3, the number of the groove 3 is equal to that of the grid strips 2, each pair of grid strips 2 is mutually inserted in the groove 3 to form a grid frame 4 which is placed in the square framework 1 to form a square resonant cavity 5, and an adjusting block is placed in the resonant cavity 5. The bottom portion of the framework 1 equipped with the grid frame 4 is equipped with a bottom board 7. The acoustic characteristic of a whole specific environment can be adjusted by disposing the audio regulating unit of the utility model on a need-to-be-processed refracting surface in a concert hall, a cinema or a multifunctional conference hall, thereby increasing audio uniformity from the audible azimuth angle and enabling high-quality sounds without superposed waves and enabling to be heard by listeners' ears.

Description

The audio frequency regulating part

Technical field

A kind of audio frequency regulating part is specifically related to a kind of environmental acoustics that is installed on the indoor plane of refraction and regulates geometry spare.

Background technology

Various sound waves are arranged in human lives's the environment, wherein can be used for transmission information and satisfy the various needs of the existence of mankind's activity by the orderly sound wave of rule; The meeting that has influences people's work and rest, even the health of harmful to human, and non-rule is unordered, is called noise.Raising day by day along with people's living standard, people are also more and more higher to the requirement of cultural life quality, when we come into concert hall, cinema or listen to the music, see a film in snapshot of oneself institute of family, company holds lecture at multi-functional conference room, when carrying out the meeting negotiation, wishes that all present everyone can hear the sound of individual lamprophonia.But in fact, since sound in communication process by refraction, the reflection of the reflecting surface of the different shape structure in room (such as objects such as wall, window, cupboards etc.), cause overlapping, the payment of node, audibility is reduced, influenced the actual effect that meeting speech, music are reduced.People are in order to improve the variety of problems that environmental acoustics in fact exists, might influence on reflection that sound wave transmits, the plane of refraction at all, designing the chamber of different geometries or face body consciously by the theoretical principle of environmental acoustics adjusts and makes sound wave under the particular environment condition, implement to transmit in an orderly manner, improve signal to noise ratio.Make the audio frequency of effective merit be transferred to clear in everyone ear, do not have a masking effect clearly.

Summary of the invention

It is a kind of in order to adjust the regulating part that harmonic wave transmits wavelength, phase place that goal of the invention of the present utility model is to provide, in certain spatial dimension, can improve audio, the transmission efficiency that improves sound wave makes people hear clear, clearly demarcated sound, has the decorative effect that beautifies household, meeting-place, theater etc. simultaneously.

The audio frequency regulating part of the said structure of the utility model, form by framework 1 and a pair of above grid bar 2, wherein said framework 1 is a square, have groove 3 on the every grid bar 2, the number of groove 3 is identical with the logarithm of grid bar 2, every pair of barrier bar 2 is inserted in mutually forms grills 4 in the groove 3, be placed on and form square harmonic shock chamber 5 in the square frame 1, is placed with regulating block 6 in harmonic shock chamber 5; Base plate 7 is equipped with in said framework 1 bottom that grills 4 is housed.

Adopt the audio frequency regulating part of the said structure of the utility model, form grills 4 in the groove 3 owing to being inserted in mutually by every pair of barrier bar 2, be placed on and form square harmonic shock chamber 5 in the square frame 1, in harmonic shock chamber 5, be placed with regulating block 6, device is on concert hall, cinema or multi-functional assembly hall domestic demand plane of refraction to be processed, just can regulate whole particular environment acoustic characteristic, improve the azimuthal sound uniformity of audible, audience's ear can be heard does not have repeatedly ripple, exposed high-quality sound.

Description of drawings

Fig. 1 is the structure explosion figure of the said audio frequency regulating part of the utility model;

Fig. 2 is the structural representation of the said audio frequency regulating part of the utility model.

The specific embodiment

Be described further below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the audio frequency regulating part of the said structure of the utility model, form by framework 1 and a pair of above grid bar 2, wherein said framework 1 is a square, owing on every grid bar 2, have groove 3, and the number of groove 3 is identical with the logarithm of grid bar 2, thereby therefore every pair of barrier bar 2 can be inserted in mutually and form grills 4 in the groove 3, grills 4 is placed on and forms foursquare one by one harmonic shock chamber 5 in the square frame 1, is placed with the regulating block 6 that adapts with harmonic shock chamber 5 in square harmonic shock chamber 5; People adjust chamber or face body consciously according to the theoretical principle of environmental acoustics, as required regulating block 6 is placed on position in the chamber face in harmonic shock chamber 5 or the chamber, what regulating block 6 height differed is placed in the harmonic shock chamber, make sound wave under the particular environment condition, implement to transmit in an orderly manner, improve signal to noise ratio.With audio frequency regulating part device on concert hall, cinema or multi-functional assembly hall domestic demand plane of refraction to be processed, just can regulate whole particular environment acoustic characteristic, improve the azimuthal sound uniformity of audible, audience's ear can be heard does not have repeatedly ripple, exposed high-quality sound.In actual applications, the framework 1 of grills 4 is installed for convenience, can base plate 7 be installed at the indoor top of using the audio frequency regulating part, and then the framework 1 of grills 4 is fixedly mounted on the base plate 7.Adopt the audio frequency regulating part of the said structure of the utility model, not only can transmit wavelength, phase place in order to adjust harmonic wave, in certain spatial dimension, improve audio, the transmission efficiency that improves sound wave makes people hear clear, clearly demarcated sound, has the decorative effect that beautifies household, meeting-place, theater etc. simultaneously.

Claims (2)

1, a kind of audio frequency regulating part, form by framework (1) and a pair of above grid bar (2), it is characterized in that said framework (1) is square, have groove (3) on the every grid bar (2), the number of groove (3) is identical with the logarithm of grid bar (2), every pair of barrier bar (2) is inserted in mutually forms grills (4) in the groove (3), be placed on and form square harmonic shock chamber (5) in the square frame (1), is placed with regulating block (6) in harmonic shock chamber (5).
