Description

Magnetic sound absorption device

Technical Field

The utility model relates to a magnetism sound absorption device is applicable to structures that have the sound absorption requirement such as quick-witted case, equipment housing, laboratory wall, smallpox, door plant.

Background

Noise is a type of sound that can cause irritation and harm to human health. Sound absorption, sound attenuation and sound insulation are generally used to reduce noise. Magnetic sound absorbers are a common noise reduction measure, are usually disposed in a noise propagation path, reduce noise by absorbing noise, and are widely used for noise control of industrial equipment.

The inner side of the steel shell is a rigid surface so as to reflect noise to cause overhigh reverberation, and secondary noise is easily excited on the surface of the steel shell. From the viewpoint of noise reduction, the sound absorption coefficient of the inner surface is increased, and the rigidity of the equipment casing is increased. The sound absorbing foam material is usually adhered to the inner side of the equipment shell, but the sound absorbing foam material is not fireproof and is easy to age, so that the sound absorbing foam material is made of magnetic materials, metal perforated plates, glass wool and other materials.

The traditional sound absorption device is formed by combining a perforated plate and a steel plate, and sound absorption materials are filled in the middle. The production of such sound absorbers has the disadvantage of being rigidly connected, not being able to be moved freely and firmly attached, etc.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a magnetism sound absorbing device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a magnetic sound absorption device comprises a main body formed by connecting a panel and a back plate, wherein a cavity is arranged in the main body, a sound absorption material is filled in the cavity of the main body, non-woven glass cloth is laid on the inner wall surface of the main body, and a magnetic material is fixed on the outer surface of the back plate.

Preferably, the panel is a perforated panel.

Preferably, the back plate is a steel plate or a perforated plate.

Preferably, the sound absorbing material is glass wool.

Preferably, the magnetic material is a magnetic strip, a magnetic block or magnetic particles.

The utility model discloses a technological effect and advantage: the magnetism sound absorbing device can need the different thickness of production, plays the best sound absorption effect, and simultaneously, panel stamping forming makes, and its outward appearance is various, plays pleasing to the eye effect, guarantees magnetism sound absorbing device's sound absorption effect, and on not influencing the basis of sound absorption effect, can satisfy the demand of outward appearance effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a magnetism sound absorbing device as shown in figure 1, be connected the main part of constituteing including panel 1 and backplate 4, be equipped with a cavity in the main part, the cavity intussuseption of main part is filled with sound absorbing material 2, and non-woven glass cloth 5 has been laid to the internal face of main part, and backplate 4's external fixed surface has magnetic material 3.

Panel 1 is the perforated plate, backplate 4 is steel sheet or perforated plate, if the surface all is the perforated plate, then the sound absorption effect is better, sound absorbing material 2 is the glass cotton, magnetic material 3 is magnetic stripe, magnetic path or magnetic particle.

As shown in fig. 10, 11 and 12, the magnetic sound absorption device has three shapes, namely a rectangle, a trapezoid and an arc, and the sound absorption devices with different shapes can be selected according to the requirements of customers, so that the attractive effect can be achieved.

As shown in fig. 2 and 3, the magnetic material 3 can be divided into four pieces or two pieces to be mounted on the back plate 4, and fully contacts with the inner side of the device housing, so as to achieve the effect of firm adsorption.

As shown in fig. 4, 5 and 6, the magnetic sound absorption device can be made into different sizes according to different requirements, and if the equipment shell is larger, the magnetic sound absorption device can be divided into standard small finished products, so that the transportation and the installation are convenient. If the apparatus housing is relatively small, the magnetic sound absorbing means may be made in two pieces or one piece.

The mounting mode of the magnetic material on the back plate is divided into a screw type (figure 7), an adhesive type (figure 8), an embedded type (figure 9) and the like, and the mounting mode is selected according to the actual production condition, so that the effect of firm adsorption is realized.
