The utility model has the advantages that: the utility model discloses a simple and easy audio amplifier sound chamber's leakproofness testing arrangement is constituteed to air supply, air-vent valve, barometer, air cock, and the air supply is the compressor, and compressor, air-vent valve, barometer, air cock all are the component of easily purchasing, and the component equipment is also very simple, with low costs, the operation is also very simple moreover, is applicable to the short-term test of small batch volume.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic diagram of the structure of the present invention;
FIG. 2 is a schematic view of the structure of the air faucet.
Detailed Description
Referring to fig. 1 to 2, the utility model discloses a simple and easy sealed testing arrangement is used to audio amplifier, including air supply 1, air-vent valve 2, barometer 3, air cock 4, air supply 1 is the compressor, air supply 1 passes through the trachea and is connected with air-vent valve 2, air-vent valve 2 and barometer 3 all are connected with air cock 4 through the trachea. Specifically, the pressure regulating valve 2, the barometer 3, and the air faucet 4 are connected to and communicated with a three-way air connector (not shown) through an air pipe.
As a further structure of the device, the device also comprises a multi-ventilation joint (not shown in the figure), the multi-ventilation joint comprises a main joint and a plurality of taps communicated with the main joint, the pressure regulating valve 2 is connected with the main joint through an air pipe, the three ventilation joints are connected with the corresponding taps through air pipes, the air nozzle 4 and the air pressure gauge 3 are connected with the corresponding three ventilation joints through air pipes, and in the structure, the air nozzle 4 and the air pressure gauge 3 are arranged and connected with the multi-ventilation joint through the three ventilation joints, so that the test of a plurality of sound box cavities at one time is realized, and the test efficiency is improved.
The compressor, the pressure regulating valve 2 and the barometer 3 in the structure are all standard parts purchased outside, the pressure regulating valve 2 is a pneumatic pressure regulating valve 2, the structure of the pressure regulating valve is not detailed, the air tap 4 is purchased outside, the main structure of the air tap 4 comprises a metal pipe 5 and a plastic head 6, and a hole communicated with the metal pipe is formed in the plastic head, so that gas is introduced into a sound cavity of the sound box.
The principle of the device is briefly described as follows: when the pressure regulating valve 2 is used, a certain pressure is regulated, the air tap 4 is inserted into an air hole reserved in the sound box and inserted into the sound cavity of the sound box, then the compressor starts pumping air, the air is pumped into the sound cavity of the sound box, the pressure regulating valve 2 is turned off after the air pressure in the sound cavity of the sound box reaches a preset value, the sound cavity of the sound box is disconnected from the compressor, the air in the sound cavity of the sound box is reserved for a certain time, then the reading of the air pressure meter 3 is seen, if the reading of the air pressure meter 3 is reduced to exceed the preset value, the sound cavity of the sound box is proved to be air-leaking, and therefore whether.
The above detailed description is made on the simple sealing test device for a sound box provided by the embodiment of the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
