Description

A kind of music reflection plate and music reflection cover

Technical field

The utility model is related to a kind of music reflection device, more particularly to a kind of music reflection plate and music reflection Cover.

Background technology

Music hall is the hall of music, be hold a concert and music correlated activation place, be that people experience music evil spirit The place of power, gives people to bring the place of the spiritual grand banquet of music, is the exquisite unique art work of a building.

When the acoustics design in theater is undesirable, cutting for the overall balance sound equipment of sound, stress and high pitch is easily influenceed Quality weak and that sound is compensated to bass can all be reduced, and reduce sound effect during its performance.One good music Not only decorate fineness in the Room, it is often more important that the tonequality of needs（Reverberation sense, sense of fullness, definition, low frequency sense, reflection, sound Field distribution is uniform, without focusing on etc.）.In order to ensure good tonequality, reflecting plate is the indispensable architectural acoustics in the professional music Room Structure, can make full use of limited natural phonation, without using public address equipment, it is to avoid audio distortions.

Reflection board structure is reflection high density aluminium honeycomb composite plate in the prior art, cellular by high density panel and aluminium foil Interlayer is constituted, the cementing two sides up and down in aluminium foil honeycomb sandwich of the high density panel.

Prior art reflection board structure has the following disadvantages：The use of the music reflection plate of composite aluminium honeycomb structure, which has, one is It is difficult adjustment after the disadvantage of row, such as angle of reflection and radian installation, after installation very unsightly, stage top light can only be bright after installation Dress, influences attractive in appearance, and light how the wind blows is not obvious, the phenomenons such as dazzle easily occurs.

Importantly, the light weight of every square of aluminium honeycomb, what the Ma Dayou recorded according to prior art was edited《Make an uproar Sound and vibration controls handbook》Middle thin plate resonant frequency calculates formula and understood, the music reflection of prior art composite aluminium honeycomb structure Plate resonant frequency is higher, causes low frequency absorption, influences the audio of music hall.

Therefore, prior art has yet to be improved and developed.

Utility model content

In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of music reflection plate and music is anti- Penetrating cover, there is provided a kind of music reflection plate that acoustic reflection performance is preferable, light transmittance is high.

The technical solution of the utility model is as follows：

A kind of music reflection plate, wherein, the music reflection plate includes：Base material, the base material is poly-methyl methacrylate Fat plate, the surface configuration of the music reflection plate is cambered surface, and music reflection plate is wherein simultaneously set to outer convex globoidal, another Face is inner concave arc surface.

Described music reflection plate, wherein, the curved structure in cross section of the music reflection plate.

Described music reflection plate, wherein, the polymethyl methacrylate plate thickness is 25mm thick, and surface density is 30KG/㎡。

Described music reflection plate, wherein, the radian of the polymethyl methacrylate plate is radius 20.607m arc.

A kind of music reflection cover, wherein, including multiple described music reflection plates, multiple music reflection plates, which pass through, to be connected Connection member is sequentially connected composition reflector.

Described music reflection cover, wherein, multiple music reflection plates are in turn connected to form door type structure；And it is many The positive stage of the outer convex globoidal of the individual music reflection plate.

Music reflection plate and music reflection cover provided by the utility model, are poly- methyl as a result of reflecting plate base material Methacrylate plate, surface configuration is cambered surface, forms a good reflector, effectively suppresses the sound absorption of low frequency；And can have What is imitated prevents acoustic energy from spilling into stage and side wall space, is absorbed without rhyme or reason by things such as the setting of there.Music of the present utility model Reflecting plate has isolated stage, the utility model enveloping space is turned into the constituent of audience space, and the sound for eliminating entablature is inhaled Receive, while the volume of auditorium is added, so as to there is provided the reverberation time in the Room, be conducive to performing music.In addition, this practicality It is new have do not break, strike it is not broken, have good impact resistance, will not have self-destruction phenomenon, and this material as safety glass Material also has good transparency and durability, and constructs and easy for installation, and angle of bend can be with Field adjustment.The utility model because Light transmittance can reach 90%, so effectively solve the bright dress of stage ceiling light and bring inaesthetic problem, light how the wind blows and dazzle The problems such as with refraction.And music reflection plate of the present utility model also has the following advantages that：

1. effectively shortening reflected sound is projected to the time of audience, so as to provide early reflection for gallery He Letai areas Sound, to increase the cordial feeling and definition of music.With more preferably sound reflecting effect.

3. can be to 2 ~ 2.5dB plus the utility model 1.5 ~ 2.5dB of sound pressure level, the especially increase of Mid Frequency sound pressure level. Because acoustic energy doubles to cause the incrementss only 3dB of sound pressure level, so 1.5 ~ 2.5dB sound pressure level increment is of great value.

4. after reflection polymethyl methacrylate plate, the reverberation time of auditorium adds about 0.4s.

5, effectively solve the bright dress of stage ceiling light and bring inaesthetic problem, light how the wind blows and dazzle and refraction etc. are asked Topic.
