Embodiment Construction

[0025] Embodiments of the present invention disclose fan noise testing equipment, such as Figure 1-8 shown, including:

[0026] Soundproof box body 1, the exterior of soundproof box body 1 is provided with soundproof box junction box 2, and the interior of soundproof box body 1 is provided with soundproof cotton 3, acoustic equipment and test fixture;

[0027] Among them, the sound insulation effect of the soundproof box body 1 should reach 25db at 200Hz, 35db at 500Hz and above, and 45db at 1KHz and above. There is a control board inside the junction box 2 of the soundproof box. The function of the control board includes providing PWM waveform to drive the fan speed, testing When the fan 14 rotates, the frequency of the square wave is generated to calculate the fan speed, and the current of the fan 14 is tested. The sound-proof cotton 3 absorbs the noise inside the sound-proof box body 1, and the inner wall and the door of the sound-proof box body 1 are provided with sound-p...

Abstract

The invention discloses fan noise testing equipment, and relates to the field of testing equipment. The fan noise test equipment comprises a sound insulation box body, a sound insulation box junction box is arranged outside the sound insulation box body, and sound insulation cotton, acoustic equipment and a test clamp are arranged inside the sound insulation box body. The equipment comprises the sound insulation box body, a test clamp, a control panel and the acoustic equipment, so the sound insulation effect of the sound insulation box body reaches 25 db at 200 Hz, reaches 35 db at 500 Hz or above and reaches 45 db at 1 KHz above; the test clamp comprises a fan fixing module and a fan connecting and switching module, the fan fixing module comprises a movable buckling arm, the movable buckling arm fixes a test fan, the fan connecting and switching module comprises a fan carrier plate and a first magnet, a bottom plate is pulled out after the fan carrier plate is laid flat, then the test fan is loaded on the fan carrier plate, meanwhile, the movable buckle arm presses the edge of the test fan, then the fan carrier plate is pushed in and turned over, and testing is conducted through a microphone on one side of the carrier plate limiting frame.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to fan noise testing equipment. Background technique [0002] In order to improve the reliability of electronic products, it is now necessary to test the speed, current and noise of notebook computer fan products in order to judge the product quality.
