Description

Tubular sound-absorbing assembly

Technical Field

The utility model relates to a inhale sound technical field, specifically be a sound subassembly is inhaled to tubulose.

Background

Low frequency noise, i.e., long wave noise, i.e., noise with a long wavelength, the wavelength unit is meter (m) or centimeter (cm), and the long wave noise refers to mechanical wave with a wavelength of more than 1.7 meters. The wavelength is 1.7-17 m, which is long wave (20-200 Hz), that is, the distance between two adjacent wave crests or wave troughs of the mechanical wave is 1.7-17 m.

Under indoor environment, the sound that equipment such as stereo set sent forms the low frequency standing wave very easily, this sound that can hear the human ear produces very big influence, seriously reduce tone quality, consequently use to inhale the sound device also called low frequency trap and absorb, and the inside concrete sound of present low frequency trap is inhaled the constitution and is then for being hollow tubular or solid cylindrical glass lap, rely on material self characteristic to absorb, the noise entering can constantly produce the refraction in inside, owing to lack to block, the noise that has partial refraction escapes from the entry, cause the influence that the sound absorbing effect reduces.

Preferably, inhale the sound pipe fitting bottom and install the base, play the effect of shutoff, sound is after the front side gets into, is absorbed by the noise elimination piece when internal propagation refraction, reduces its and flees outward.

Preferably, the base is the toper setting of high all around end in the middle of being, and the sound wave of propagation or refraction to on the base can form to inhaling the refraction of sound pipe fitting inner wall, and then absorbs with the contact of noise elimination piece once more, ensures to inhale the sound effect.

Preferably, the downward sloping of noise elimination piece sets up, and when the sound wave entered into, the contact noise elimination piece top surface can be refracted to inhaling the sound pipe fitting inner wall, then refract again and get into the route to cause the interference, the noise is difficult for escaping, and when the sound wave was in the inboard through refraction and noise elimination piece bottom surface contact, then can be to inhaling the inboard refraction of sound pipe fitting because of the slope structure of noise elimination piece, the noise is harder to escape, the sound effect is inhaled in the guarantee.

Preferably, the first fins and the second fins are uniformly arranged at the bottom of the lower sound-absorbing plate, so that the noise absorption effect is improved.

Preferably, the first fins and the second fins are arranged at equal intervals, the height of the first fins is larger than that of the second fins, penetration and refraction are formed when noise is absorbed incompletely at one time, noise sound energy consumption is improved by staggered use, and then the sound absorption effect is achieved.

(III) advantageous effects

Compared with the prior art, the utility model provides a sound subassembly is inhaled to tubulose possesses following beneficial effect:

1. this sound subassembly is inhaled to tubulose through inhaling the inside noise elimination piece that sets up of sound pipe fitting, when the noise sound wave gets into inside, through the contact with noise elimination piece and the continuous refraction in inside, carries out continuous conversion absorption and consumption to its sound energy to reach sound absorbing effect, the structure is simple relatively, and sound absorbing effect is stable.

2. This tubulose inhales sound subassembly, through addding fin one and fin two, the noise once absorbs formation when incomplete and pierces through and refracts, divides the mistake to use the consumption that improves noise sound energy in inside, and then reaches sound absorbing effect.
