The following describes the technical scheme of the embodiment of the present utility model in detail with reference to the accompanying drawings.

Example 1

Referring to fig. 1-3, fig. 1 is a schematic structural diagram of a honeycomb rock board soundboard according to an embodiment of the present utility model.

The honeycomb rock plate soundboard comprises a rock plate layer 1, a honeycomb core layer 2, a glass fiber resin layer 3 and an audio vibrator 4. The rock plate layer 1, the honeycomb core layer 2 and the glass fiber resin layer 3 are sequentially laminated from top to bottom. Specifically, an adhesive layer is further disposed between the rock plate layer 1 and the honeycomb core layer 2, that is, the rock plate layer 1 and the honeycomb core layer 2 are glued together by an adhesive, and meanwhile, the honeycomb core layer 2 and the glass fiber resin layer 3 are glued together by an adhesive, so that after the adhesive is cured, the rock plate layer 1, the honeycomb core layer 2 and the glass fiber resin layer 3 can form an integral sounding board. The audio vibrator 4 is adhered to the glass fiber resin layer 3 by an adhesive. Specifically, a sound source sounding station is arranged on the glass fiber resin layer 3, and the audio vibrator 4 is arranged on the sound source sounding station. More specifically, the audio vibrator 4 is adhered to the sound source sounding station by an adhesive.

The rock plate used by the rock plate layer 1, also called a ceramic rock plate, has the characteristics of large specification, multiple sizes, high hardness, wear resistance, scratch resistance and the like, and is widely applied to background walls at present and is popular with the masses. The honeycomb core used by the honeycomb core layer 2 is an aluminum honeycomb core, and the aluminum honeycomb core has the characteristics of light weight, high strength, good rigidity and the like, and can reduce the weight of the whole soundboard and improve the strength of the soundboard. The glass fiber resin layer 3 adopts alkali-free glass fiber resin, and the honeycomb core and the glass fiber resin form a honeycomb flat plate, so that the structural strength can be enhanced, the rock plate can be compounded, and the rigidity of the whole sound plate can be further improved. The audio vibrator 4 is a vibration device for emitting audio, and is mainly used for providing audio vibration signals and driving the honeycomb panel to emit sound; in actual use, the audio vibrator 4 may be a driver or a vibrator.

Further, in order to enable the sounding board to better sound, the sound source sounding station is arranged in an area between the center of the rock board and the edge, the center of the rock board is the center of gravity of the rock board, and the edge is an area of 1/5 of the distance between the side edge of the rock board and the center of the rock board. When the audio vibrator 4 vibrates and emits audio, each area unit on the honeycomb core layer 2 can vibrate irregularly and independently, so that each area unit can become a micro-speaker and radiate an uncorrelated signal, and each uncorrelated signal is finally synthesized and directly output onto the flat mechanical impedance with constant relative frequency, so that the rock plate vibrates uniformly in the audio range, and sound waves are effectively amplified and propagated to the outside.

In order to further improve the tone quality of the soundboard, a sealing layer 6 is further arranged on the periphery of the honeycomb core layer 2; the upper plane of the sealing layer 6 is in contact with the rock laminate layer 1, and the lower plane of the sealing layer 6 is in contact with the glass fiber resin layer 3. The sealing layer 6 may be made of glass fiber resin. The edges of the honeycomb core layer 2 are sealed through the sealing layer 6, so that the honeycomb core layer 2 can form a sealed space between the rock plate layer 1 and the glass fiber resin layer 3, noise generated by cracking and breaking of the whole plate is avoided, and the tone quality effect of the whole honeycomb rock plate soundboard is further improved.

Since the weight of the soundboard affects the sound quality of sound of the soundboard, in order to ensure higher sound quality of sound, preferably, the thickness of the rock plate layer 1 is 2-4mm, more preferably, the thickness of the rock plate layer 1 is 3mm, and by adopting an ultra-thin rock plate, the high-pitched sound producing ability of the rock plate is further enhanced. The thickness of the glass fiber resin layer 3 is 1mm, and the thickness of the honeycomb core layer 2 is 6mm, so that the honeycomb panel has the characteristics of small mass, good rigidity, flatness and good integrity, and can better match with the large, medium and small sizes of the rock plate to emit low, medium and high tones. It should be noted that the rock board used in this embodiment may be of various sizes, and preferably, the rock board of the rock board layer 1 has a long side width of 1-3.2m and a short side width of 0.8-1.6m.

Through testing, as shown in fig. 3, the honeycomb rock board soundboard has a relatively flat response curve in the audio frequency range of 50Hz-16KHz, which shows that the honeycomb rock board soundboard has almost full-band audio sound emission capability in the audio frequency range of 50Hz-16 KHz. Moreover, the rock plate has a large-sized characteristic, but when the rock plate is used, the sound volume of the entire honeycomb rock plate sound plate is not attenuated with the increase of the rock plate size.

In the first embodiment, the honeycomb rock plate soundboard provided by the utility model comprises a rock plate layer, a honeycomb core layer, a glass fiber resin layer and an audio vibrator, and the honeycomb core and the glass fiber resin are adopted to form a honeycomb flat plate, so that the structural strength can be enhanced, the rock plate can be compounded, and the rigidity of the whole soundboard can be further improved. By arranging the audio vibrator on the glass fiber resin layer, when the audio vibrator vibrates and emits audio, each area unit on the honeycomb core layer is driven to perform independent irregular vibration, so that each area unit can become a micro loudspeaker and radiate an uncorrelated signal, and each uncorrelated signal is finally synthesized together, so that the rock plate uniformly vibrates in the audio range, and sound waves are effectively amplified and spread to the outside. Compared with the prior art, the rock plate is endowed with a vocal function, so that the rock plate can emit attractive sound, the use of the audio device is effectively reduced, the installation program is simplified, the whole application scene is concise and attractive, the use function of the rock plate is further expanded, the precedent of using the rock plate as a soundboard is opened, and the rock plate has very important significance.
