In our work and days, and during our studies, we often need to use headsets. The headsets are closely related to our ears. In the course of long-term use of headsets, we should not only pay attention to the quality of the sound, but more importantly, To think about the health of our ears, here's a good introduction for you to recommend a headset that will help you choose the best quality headphones.
The headset is an integrated headset and microphone, which is different from the usual headphones. Usually the earphones are often stereo, and the headsets are mostly monophonic. Together, the headsets have microphones that are usually not available in the headset. Earphones can be divided into closed, open and semi-open styles. The closed type is to wrap your ear with its own soft pad, so that it is completely covered up. Due to the large sound pads, these headsets are quite large, but they can be used in a noisy environment without affecting them. Open headsets are the prevailing styles of headsets. The feature of this type of machine is through the use of sponge-like microcellular foam plastic made acoustic ear pads. It is compact and comfortable to wear. It is no longer the use of heavy sound pads, but also no sense of blocking with the outside world, but its low frequency loss is greater. The semi-open headset is a new type of headset that combines the advantages of both closed and open headsets. The headset uses a multi-diaphragm structure. In addition to an active active diaphragm, there are multiple passive passive diaphragms. It not only has the fullness and richness of low-frequency depiction, but also has the characteristics of bright and natural, high-level and clear features depicted by high-frequency.
In our assignments and days, and during the study, we often need to use headsets. The effect and function of headsets I think most people have a consensus. It is not only convenient for us to expand the volume and communicate more clearly with people. Together, it is also beneficial to the health of the throat. However, due to the high frequency of use of headsets, questions often arise in the process of use. The most common problem is that headsets cannot speak. Many consumers often suspect that they have not bought a headset when they encounter such questions. Even real branded products for headsets are not all that way. So how do we deal with this question? Here we come to a specific understanding of the common questions and treatment of headsets.
Headsets are very common devices in cybercafes, and their damage is also great. The lines used by the headset are relatively thin. After eating the rough movements of netizens such as pulling and twisting, the headset line is easily broken. Most of the problems of the headset are caused by the cracking of the headset line. The chief complaints of headsets are:
(1) Headphones do not ring or do not ring;
(2) The microphone is silent;
(3) Loss of volume adjustment.
Today's headsets usually incorporate headphones and microphones together so that there are two sets of cords, one for a total of three headphone cords and the other for a total of two microphone cords. One of the three lines of the headset is the bus, and the other two are for the vocal channel respectively, and the earphone plug part is also divided into three segments. The on-off of the headphone cable can be checked by a multimeter, and only two of the three-piece connectors of the headphone plug can be separately measured by the meter pen. If it is a pass, a subtle "click" sound is heard in the headphone. The earliest local breakage of the headset line is at the local area where the volume is adjusted, the earphone lead-out area, and the two coil joints. When repairing, the demand is careful, and the cracked thin wire can be welded from the beginning, and each joint should be wrapped with tape. If there is something wrong with the module that regulates the volume, then the Shuangxin will be removed directly here, and the connection between the two ends can be welded directly. Originally, repairing headsets did not have much technicality. We only needed patience and care for our headsets. We only needed to repair them several times and understand their internal structures. Naturally, we can do our job well.
