Abstract
A step regulation acoustic box relates to the technical field of acoustic treatment and comprises a box body. The box body is formed by mutually connecting and enclosing a top board, a bottom board, a left board, a right board, a front panel and a rear panel through fixing strips. A reinforcing strip and support boards are further disposed in the box body, the reinforcing strip is disposed in the middle of the inner side of the front panel, the middles of the support boards are fixed on the reinforcing strip, and two ends of each support board are fixed to the inner side of the left board and the inner side of the right board respectively. The step regulation acoustic box is characterized in that the rear panel is provided with a plurality of acoustic holes, a rubber plug is disposed in each acoustic hole and can be optionally unplugged from or plugged into the acoustic holes. The step regulation acoustic box has the advantages that frequencies of indoor low-frequency acoustic waves to be absorbed are regulated according to the number of opening acoustic holes, and accordingly, different low frequencies can be absorbed selectively, certain low frequencies can be absorbed purposefully, and the step regulation acoustic box is simple in structure and convenient in operation.
Description
Technical field
The present invention relates to building interior decoration Acoustic treatment technical field, be specifically related to a kind of step-wise adjustment sound-absorbing case.
Background technology
In the building interior decoration space of all kinds of sound recordings and playback, for example: in the interior decoration spaces such as recording room, control room, audiovisual studio, home theater, the design and the processing of indoor tone quality is absolutely necessary.Especially the sound absorption of indoor wall is handled and to be eliminated harmful strong reflection sound, avoid the focusing of sound, reduce the room reverberation time, reduce the reverberation sound level, improve the definition of sound.At present, mainly there are following two defectives in the sound arrester that occurs on the market: the one, the low-frequency band absorptive capacity of sound wave a little less than, mostly be to be main to absorb the medium-high frequency sound wave, so just be difficult to the real reverberation problem that solves; The 2nd, whole sound arrester volume is too huge, and structure is more complicated also, needs the Installation and Debugging personnel of bigger installing space and specialty, and not only the field of employment is limited, and operation technique is difficult to control, and decorative effect is also poor.
Chinese patent number " 200610087311.1 " discloses a kind of adjustable sound-adsorption device; Comprise entrant sound decorative cover, adhesive layer, the fixing installing frame of perforated plate, movable perforated plate, Vidacare corp, damping material and specific thicknesses; Its improvements are: in this sound arrester; Through Vidacare corp, the change activity perforated plate and the fixing relative position of perforated plate can align the hole of two perforated plates and also can misplace; Effective perforated percentage is changed, thereby can carry out the adjusting of acoustical absorbance properties.Though these innovation and creation can effectively realize the change through perforated percentage, change the height that absorbs sound frequency, still; Its structure is too complicated, in case this device goes wrong, maintenance cost will increase greatly; And, to user's ability and technical requirements also than higher.
Summary of the invention
It is a kind of simple in structure that the technical problem that the present invention solved is to provide, and is convenient to operation, and can effectively absorb the step-wise adjustment sound-absorbing case of sound wave low frequency.
The technical problem that the present invention solved adopts following technical scheme to realize:
A kind of step-wise adjustment sound-absorbing case; Comprise a casing, said casing is to interconnect the system of enclosing by upper plate, lower shoe, left plate, right plate, front panel and six blocks of plates of rear board through fixed strip to form, and in said casing, is provided with stiffener and fagging; Said stiffener is located at the middle medial surface of said front panel; The center fixed of said fagging is on said stiffener, and the two ends of said fagging are separately fixed at the inboard of said left plate and right plate, it is characterized in that: on said rear board, be provided with a plurality of sound-absorption hole; In each said sound-absorption hole, be equipped with rubber stopper, said sound-absorption hole can freely extracted and clog to said rubber stopper.
The cross section of said casing is trapezoidal, rectangle, square, triangle or other polygons.
Said fagging be shaped as V-arrangement, the quantity in said casing is 1 or 2.
Said sound-absorption hole is located at the below of said rear board; Said sound-absorption hole becomes rectangular array on said rear board; The quantity of said sound-absorption hole on said rear board is >=20; Being shaped as of said sound-absorption hole is circular, square, triangle or other polygons.
The quantity of said rubber stopper and shape all match with the quantity and the shape of said sound-absorption hole, and said rubber stopper is extracted quantity from said sound-absorption hole the said casing that how much determined absorbs the different frequency of sound wave low frequency.
Said casing can absorb 25HZ with interior sound wave standing wave when said rubber stopper was extracted 1 from said sound-absorption hole; Said casing can absorb 33HZ with interior sound wave standing wave when said rubber stopper was extracted 2 from said sound-absorption hole ... Specifically absorb shown in the sound wave standing wave frequency meter like step-wise adjustment sound-absorbing case.
The beneficial effect that the present invention has is: realize what adjusting of low-frequency sound wave in the absorption chamber through the quantity of opening sound-absorption hole, like this, not only sound-absorbing effect is obvious, and simple in structurely is convenient to operation.
