Description

technical field [0001] The invention belongs to the measurement and adjustment equipment for manufacturing sound-producing equipment parts, in particular to an air flow adjustment machine. Background technique [0002] In order to improve the overall frequency response and optimize the quality, for the production of the microphone head, the coordination between the tuning paper on the microphone head and the sound head body and how much air flow can be generated, the relevant microphone head overall quality. [0003] Generally, before the tuning paper of the microphone capsule is assembled on the capsule body, the air permeability of the tuning paper is fixed. If the air flow rate is lower than the preset range, manual perforation must be performed; if the air flow rate is higher than the predetermined range, manual glue filling must be performed. That is to say, the air flow between the microphone capsule body and the tuning paper is usually controlled by manual perforati...

Problems solved by technology

[0004] However, although artificial perforation and glue filling are generally used to adjust the airflow of the microphone capsule, such methods must be tested only after the tuning paper has been pasted on the microphone capsule body, which is not only troublesome and inconvenient, but also efficient Poor, and, in the way of manual operation, the holes have different calibers, which must be controlled by the experience of technicians; and because the tuning paper itself is coated with glue to stick to the sound head body, not only because of artificial To pierce the tuning paper, so that the caliber is different, and the caliber is easy to restore and not fixed, which not only makes the production process complicated and inefficient, but also the quality is uneven, which damages the goodwill and seriously affects the production volume.
