Abstract
The utility model provides a mural painting audio amplifier, include: frame, canvas, vibration exciter, switch, power amplifier module and lithium cell, the canvas is installed on the frame, and the canvas encloses into installation space with the frame, and vibration exciter, power amplifier module and lithium cell are all installed in installation space, and the switch mounting is on the side frame of frame, and the back at the canvas is pasted to the vibration exciter, and the vibration exciter passes through the switch to be connected with the power amplifier module, and the lithium cell supplies power to the power amplifier module. The utility model discloses the volume is minimum, can install on the canvas of arbitrary area, simultaneously because of its vocal principle for utilizing the canvas resonance sound production, so that sound generating component's area is bigger, can produce better bass, and its high pitch part also has certain change according to the difference of canvas material, consequently can say that each picture all has its distinctive tone quality. Furthermore, the utility model discloses possess the sound production medium, adopt vibration sound generating mechanism to form resonance loudspeaker, can directly carry out the music broadcast.
Description
Technical Field
The utility model relates to a audio amplifier field, in particular to mural painting audio amplifier.
Background
In the prior art, the conventional sound box has the following two modes:
first, mural audio amplifier and oil painting audio amplifier. In a conventional mode in the prior art, an external sound box and a mural sound box composed of a power amplifier, a battery, a power supply and the like are added at the back of the oil painting, so that the volume of the sound box is small, and the small sound box cannot generate good tone quality and strong bass quality when music is played.
Secondly, the resonance loudspeaker box is utilized, but the resonance loudspeaker is fixed on a plane to generate music with enough volume, and the equipment does not have the material and the capability of sound production.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mural sound box to solve at least one above-mentioned technical problem.
In order to solve the above problem, as an aspect of the present invention, there is provided a mural sound box, including: frame, canvas, vibration exciter, switch, power amplifier module and lithium cell, the canvas is installed on the frame, the canvas with the frame encloses into installation space, vibration exciter, power amplifier module and lithium cell are all installed in the installation space, the switch mounting is in on the side frame of frame, the vibration exciter is pasted the back of canvas, the vibration exciter passes through the switch with the power amplifier module is connected, the lithium cell to the power amplifier module power supply.
Preferably, the power amplifier module is a bluetooth power amplifier module.
Since the technical scheme is used, the utility model discloses the volume is minimum, can install on the canvas of arbitrary area, simultaneously because of its vocal principle for utilizing canvas resonance sound production, because of the area of sound production component is bigger, can produce better bass, its high pitch part also has certain change according to the difference of canvas material, consequently can say that each width of cloth painting all has its distinctive tone quality. Furthermore, the utility model discloses possess the sound production medium, adopt vibration sound generating mechanism to form resonance loudspeaker, can directly carry out the music broadcast.

Reference numbers in the figures: 1. a picture frame; 2. a canvas; 3. a vibration exciter; 4. a switch; 5. a power amplifier module; 6. a lithium battery.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
The utility model discloses an aspect provides a mural audio amplifier, has solved current mural audio amplifier volume thickness too big, and the not enough shortcoming of bass, can utilize current oil painting to reform transform through non-destructive through the while and to make current oil painting reform transform into the mural audio amplifier.
This mural audio amplifier includes: frame 1, canvas 2, vibration exciter 3, switch 4, power amplifier module 5 and lithium cell 6, canvas 2 is installed on the frame 1, canvas 2 with frame 1 encloses into installation space, vibration exciter 3, power amplifier module 5 and lithium cell 6 are all installed in the installation space, switch 4 is installed on the side frame of frame 1, vibration exciter 3 is pasted the back of canvas 2, vibration exciter 3 passes through switch 4 with power amplifier module 5 is connected, lithium cell 6 to power amplifier module 5 supplies power. Preferably, the power amplifier module 5 is a bluetooth power amplifier module.
Wherein, canvas 2 can be mounted according to the mural painting requirement of various differences to at the movable part, probably produce the position of resonance noise and paste the sponge and carry out the shock attenuation, perhaps adopt other shock attenuation fillers to fill with the noise that produces because of the canvas vibration when reducing and completely cut off the broadcast. In addition, can carry out the trompil according to the size of switch and power hole as required in the frame side for installing switch and power hole, if there is special demand to carry out the trompil according to the type that adopts the power amplifier.
Preferably, the vibration exciter 3 adopts a small-sized resonance exciting unit, different powers can be selected according to the material and the size of a canvas, the general type adopts an 8 ohm 10 watt resonance exciting unit, the exciting unit is pasted in the center of the canvas by glue, and a connecting wire is wrapped by sponge.
Preferably, the power amplifier module 5 defaults to adopting a 12v direct current bluetooth power amplifier integrated power amplifier board, and makes a plastic or wooden original paper box with a proper size for installing and fixing the power amplifier board and the battery. Survey in being fixed in the frame original paper box through the screw, outside parcel sponge to be connected switch, power mouth etc. with wire and power amplifier, switch and power mouth are installed in the opening part of frame, and connecting wire wraps up with the sponge. If special function needs, other types of power amplifiers can be adopted, and the power amplifiers can be installed in a picture frame when the size is small.
Preferably, the lithium battery adopts a 12v lithium battery with a protection plate within 2 cm of thickness. And fixing the materials in the power amplifier box by using glue, and wrapping sponge if necessary.
In the technical scheme, the utility model discloses utilize a characteristics of oil painting mounting, the canvas of oil painting or rigid drawing board promptly, perhaps tight canvas all can be used for carrying out the resonance sound production as the medium of resonance sound production to paste vibration exciter 3 the back of canvas 2 constitutes the audio amplifier.
Preferably, the vibration exciter 3 can adopt a 1.75-inch flat-plate vibration resonance exciter of a 44MM vibration resonance full-frequency horn electronic photo frame.
Since the technical scheme is used, the utility model discloses the volume is minimum, can install on the canvas of arbitrary area, simultaneously because of its vocal principle for utilizing canvas resonance sound production, because of the area of sound production component is bigger, can produce better bass, its high pitch part also has certain change according to the difference of canvas material, consequently can say that each width of cloth painting all has its distinctive tone quality. Furthermore, the utility model discloses possess the sound production medium, adopt vibration sound generating mechanism to form resonance loudspeaker, can directly carry out the music broadcast.
