Description

Full-automatic quality detection device for high-sound quality earphones

Technical field

The invention relates to a quality detection device, in particular to a full-automatic quality detection device for high-sound quality earphones.

Background technique

The earphone is a pair of conversion units, which accepts the electrical signal sent by the media player or receiver, and converts it into audible sound waves by using a speaker close to the ear. The headset is generally detachable from the media player and connected with a plug. The advantage is that it can listen to the sound alone without affecting others; it can also isolate the sound of the surrounding environment, which is very helpful for people who use it in noisy environments such as recording studios, DJs, travel, sports, etc. Earphones were originally used on phones and radios, but with the prevalence of portable electronic devices, earphones are mostly used in mobile phones, walkmans, and radios. Portable video games and digital audio players, etc.

Quality inspection: refers to the activity of checking and verifying whether the quality of products or services meets relevant regulations. It is divided into air quality testing, engineering quality testing, product quality testing, environmental quality testing and so on. Quality testing can sometimes be called testing or experimentation, which refers to the technical operation of determining one or more characteristics or performance of a given product, material, equipment, organism, physical phenomenon, process or service in accordance with a prescribed procedure. In order to ensure that the test results are accurate to a certain extent, it must be carried out within the prescribed detection range and in accordance with the prescribed procedures.

After the last process of the headset is completed in the factory assembly line, the final quality inspection is required before it can be packaged and sold. The most important quality test of a headset is to test its sound quality, which mainly detects whether the quality of the headset is qualified in terms of frequency response and noise. In general enterprise workshops, workers are mainly inspected by their own hearing. Due to the existence of the worker's own subjective factors, this detection method is very unscientific. At the same time, there is a problem of auditory fatigue, which can easily cause the workers to make wrong judgments and make the product quality problems undetectable.
