Description

  The present invention relates to a hearing aid, and more particularly, to a hearing aid that can select a power supply method and is convenient for a user when going out.

  Hearing aids are the greatest gospel for people with hearing impairments. In addition, by providing various functions according to the type and degree of hearing impairment, it is possible to meet different needs of individual users. Speaking from the current technology, the hearing aid functions are programmed, and even a minute speech change automatically reacts to output a speech signal, providing clear and easy-to-hear speech and contributing to the comprehension ability by speech. It became possible to do.

  However, many conventional hearing aids lack the adjustment function in the design of the body structure. For this reason, the input sound range is narrow. Moreover, the battery is used as a power source, and most of the batteries employ a primary battery. For this reason, when the battery is replaced due to insufficient power, the user must open the housing of the main body, which is very small in volume, and take out the mercury battery whose power is consumed and insert a new mercury battery. However, in view of the current situation that elderly people account for the majority of hearing aid user groups, it is extremely inconvenient and burdensome for users to constantly replace batteries.

The shortcomings of conventional hearing aids are summarized as follows.
1. The parts of the hearing aid are very small, and it is difficult for a user with weak vision to align the position of the parts.
2. The size of the hearing aid battery is extremely small, making it difficult to distinguish between positive and negative electrodes. For this reason, when replacing the battery, the top and bottom surfaces may be reversed. In this case, the battery cover is in a state of being caught, and when the battery cover is pressed as it is, the engagement structure portion of the battery cover is destroyed, the battery cannot be fixed and is damaged. Therefore, it becomes a main cause of shortening the service life of the hearing aid.
3. A battery generally used for a hearing aid has a small volume, and when the time for using the hearing aid is set to 6 hours, power is consumed in five days. If 8 hours a day, one battery will be consumed in 3,75 days. That is, about 100 batteries are used in one year, and a cost of 100 times the unit price of the battery occurs. Therefore, discussing only the price point does not fit very well with economic principles.
4. As mentioned above, conventional hearing aids consume about 100 batteries per year. Such a large amount of used batteries may cause serious environmental pollution problems if they are not sufficiently collected.
5. The conventional hearing aid must be performed in a bright place where sufficient light can be obtained when the power is consumed and replaced during use. Therefore, for example, when you are in a movie theater, outdoors at night, or when you are in a car at night, you can not get enough light to perform battery replacement work, so it is not very inconvenient, If you can't replace the battery, your hearing will be temporarily impaired. Therefore, it is not ideal.
