With the progress of society, audio has been constantly improved and perfected in line with people's needs. From meeting the needs of live sound reinforcement for tens of thousands of people at concerts to meeting the needs of individuals playing musical instruments and singing karaoke at home, the use of audio is indispensable.As a playback device, people have extremely high requirements for air tightness of speakers.This time, Hirays Technology will conduct equipment operation training for customers who perform air tightness testing of portable audio equipment. This training is designed to strengthen customers' use of equipment and management, reduce operators' operating errors on air tightness testers, and deepen operators' familiarity with the use of equipment. The following is an on-site demonstration of this training by Hirays Technology.

1. Audio appearance display and analysis of detection difficulties

In order to let customers understand the testing process and principles in more detail, Hirays training staff conducted an in-depth analysis of the appearance of this speaker:

1. This speaker is compact in appearance. The irregular shape has several concave closed sound outlets. In the middle of the speaker is a concave sound membrane. The sound membrane is in direct contact with the internal electronic devices. The outside is wrapped with black waterproof shell material;

2. The special structure of the speaker makes it difficult to detect the sealing. During the early design and production process of the motor, its shell will undergo special treatment, and the speaker has many closed sound holes, so it is impossible to use a mold for fully enclosed inspection during inspection;

2. Breakthrough in Difficulties in Audio Air Tightness Detection

1. The training staff of Hirays explained to the customer the principle of the air tightness test of the audio. Regarding the special shape of the audio, Hirays Technology has specially customized a tooling jig for the audio. Since this speaker has a concave sound film in the middle, and there are many small openings in the middle of the sound film, we can first put the side with the sound film upward and put it into the mold. During the test, the upper tool will move downward and be stuck on top of the sound film to fix it;

2. When the instrument is started, the instrument will inflate the sound into the speaker through the upper device. At the same time, the air pressure of the instrument will slowly rise. When the air pressure reaches the set value, the interior of the sound will be in a constant state. At this time, the sensor will determine the flow value to detect whether the flow rate of the echo tube meets the standard.

3. Analysis of on-site operation training of audio air tightness detector

1. At the beginning of the test, Hirays training personnel will explain the use of the audio air tightness testing equipment, allowing customers to use the audio air tightness testing equipment correctly and carefully maintain it to achieve the best use results.In this link, we require customer staff to operate the mobile phone in person to experience and become familiar with the operation process.

2. Finally, Hiraysi Technology explained to customers the maintenance work of the audio air tightness detector, including cleaning, lubrication, inspection, monitoring, adjustment, tightening and arrangement of the equipment.

4. Parameter table of audio air tightness detector

This training service of Hirays Technology has been highly recognized by customers. After personnel training, the equipment can be quickly operated, which reduces the company's training cycle for personnel and speeds up the investment in audio air tightness detectors for production line testing.
