Why does the hearing aid not work?
hearing aids, a kind of loudspeaker that helps the hearing impaired to improve their hearing and thus improve their verbal communication skills. With the development of microelectronics technology, hearing aids have become increasingly miniaturized and miniaturized. There are four basic types of hearing aids: box, eyeglass, and ear-in-the-ear and in-ear (ear canal). Hearing aid is the only high-tech in the modern society that must be worn at any time in daily activities. It is very sophisticated and can be used in a variety of harsh weather conditions and living environments. Electronic products, for various reasons, are destined to be well maintained in order to get the best results. From the results of research on custom machines in recent years, it has been found that ear wax is blocked, damp, and inadvertently dropped, which are the three main causes of hearing aids, especially for custom machines. 1. Damage to earwax The blockage of earwax is the main cause of damage to expensive receivers. Chinese earwax is generally dry. Normally during normal speech, chewing, walking, most of the earwax will gradually vibrate out of the ear canal due to vibration, but some will remain in the ear canal, especially when wearing custom. After the machine, the ear canal is blocked, the earwax can not fall out normally, and the earwax can't go to the receiver hole of the machine. The light makes the sound lighter, and the seriousness causes the receiver to be seriously blocked and damaged. Come to unnecessary losses. Regular cleaning of the receiver hole requires the dealer and the user to work together. Do not underestimate the small earwax, which may bring you huge losses and inconvenience. Cleaning the earwax according to the instructions in the manual will not take much time, but it can save you a lot of maintenance costs and avoid the pain of inorganic wear. 2. Hazards of water vapor One of the biggest enemies of hearing aids is water vapor. It is generally known that water vapor will enter and accumulate inside the hearing aid from the gap between the battery compartment door and various adjustment knobs, affecting the internal wiring of the hearing aid, causing the volume of the internal cavity of the custom machine casing to store moisture, corrosive movement and internal wiring. Therefore, in normal use, be careful not to let the water vapor from the surrounding environment enter the hearing aid, such as adjusting the hearing aid with wet hands or showering the rain. It is not known that water vapor can enter the receiver cavity from the receiver hole of the custom machine. In the southern part of China, the high temperature period is very long throughout the year, so it is often washed and showered every time. The homework that must be done, usually after a shower in the shower, it is inevitable that a small amount of water will splash into the ear canal. A normal person's ear canal will have a little water to evaporate quickly, but if the deaf person wears a custom machine without drying in the ear canal, it will completely block the water between the custom machine and the eardrum. In the channel space, the water becomes water vapor after being heated, enters the cavity of the receiver, and then gradually cools and accumulates into liquid water. The extremely small parts in the receiver are continuously immersed, and the receiver is damaged, and the sound is abnormal. Reimbursement of the receiver. It is important to note that it is important to keep the ear canal dry. When the hearing aid is not in use, it should be placed in the desiccant to absorb the moisture from the machine, which will give your hearing aid a very long service life. 3. Impact damage The hearing aid is very afraid of falling like a quartz watch, because the components in the hearing aid are connected by very small wires, which are very easy to break after being impacted, especially the internal sounding vibration of the receiver due to its structural relationship. Reeds and thimbles are very easy to displace and deform after impact, causing distortion or silence. In the production process of the receiver, if there is a fall from a height before the receiver is packaged, the only way to deal with it is to scrap, and the receiver is not resistant to shock. . After the receiver is installed in the hearing aid casing, although the impact resistance is improved, it is still highly important to prevent the impact from falling. Due to its small size, the custom machine is easier to slip off the hands when wearing or removing, so be sure to pay attention to this.
