Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] As shown in the figure, an earphone waterproof test device includes a base 1, a cylinder 2 and a piston 3 placed in the cylinder 2 are arranged on the base 1, and the piston 3 moves on the cylinder 2 under the action of external force. Swipe up and down.

[0026] A spring 4 is arranged between the piston 3 and the bottom of the cylinder body 2, and the spring 4 is compressed under the action of an external force, and the elastic force of the spring 4 makes the piston 3 reset when the external force is lost. A through hole 31 communicating with the cylinder body 2 is provided in the piston 3 , so that the space in the cylinder body 2 can communicate with the outside through the through hole 31 . In this way, when the piston 3 is pressed down, the gas in the cylinder 2 passes through the through hole 31, so that the air pressure in the cylinder 2 is the same as the air p...

Abstract

The invention discloses an earphone waterproof test device, which comprises a base. The base 1 is provided with a cylinder and a piston arranged in the cylinder, a spring is arranged between the piston and the bottom of the cylinder, a through hole communicated with the cylinder is arranged in the piston, a location structure capable of locating products to be tested is arranged at the upper end of the piston, an annular sealing pad where products can be pressed to be tested is arranged on the location structure, and the cylinder, the through hole, the annular sealing pad and products form a sealed cavity. The method for testing earphone waterproof effects comprises the following the steps of preparing before testing, and arranging products to be tested on the location structure to form the sealed cavity through the cylinder, the through hole, the annular sealing pad and the products; testing, pressing the products downwards, raising pressure, and reading actual pressure in the cylinder through a pressure meter; and judging earphone waterproof effects. Due to difference of waterproof performance of the products, pressure change in the cylinder is different. By observing the pressure change, waterproof performance of the products can be measured.

Description

【Technical field】 [0001] The invention relates to a method for testing the waterproof effect of earphones and a device for testing the waterproof effect of earphones produced by the method. 【Background technique】 [0002] At present, there is a new type of waterproof earphone. The waterproof effect needs to meet the requirements of the national standard (GB4208) or the international standard (IEC529) of IPX7 level. It adds a waterproof and breathable membrane outside the vibrating membrane of the earphone speaker. In actual production, the waterproof membrane may be damaged, or there are defects in the bonding of the waterproof membrane, which will reduce the waterproof level of the waterproof earphones. carry out testing. [0003] The present invention is made under such circumstances. 【Content of invention】 [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for testing the waterproof performance of earpho...
