置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an educational amplifier for the hearing-impaired, which includes an element that amplifies a signal from a microphone and supplies it to headphones, and adjusts acoustic characteristics such as compression and frequency characteristics to suit the user. It is related to the device.

徒の聴覚障害度に合わせて一旦調整すると、その生徒は
いつも同じ机で授業を受ける。Known amplification devices of this type are permanently integrated into desks for hearing-impaired students, and the acoustic characteristics of the amplification device are individually adjusted to the hearing-impaired student sitting at the desk by adjusting elements. Adjusting such amplification devices to suit a student's degree of hearing loss can only be done by a professional and is extremely time consuming, so it is important to adjust the amplification device of a particular student's desk to suit the student's degree of hearing loss. Once adjusted, the student always attends class at the same desk.

容するようにしたことを特徴とするものである。Therefore, it is impossible to exchange desks for the hearing-impaired within the same classroom or with desks for students in other classrooms. An object of the present invention is to provide an amplification device that is not subject to the above-mentioned limitations. The amplification device of the present invention is for use in education for the hearing-impaired, and is equipped with a plurality of adjustment elements that amplify a signal from a microphone and supply it to headphones, and adjust a plurality of acoustic characteristics such as compression and frequency characteristics to suit the user. The amplifier device is characterized in that the plurality of adjustment elements are housed in a separate plug-in unit that is connected to the amplifier device by a plug.
したがつて、本発明によれば、調整素子は増幅Ｊ 装置

々の調整を行なうことができる。Instead, each student now carries a dedicated plug-in unit containing adjustment elements tailored to his or her level of hearing loss. When each student moves,
Simply remove your plug-in unit, ie pull it out of the amplifier and insert it into the amplifier of another student's desk. In addition, it is necessary that all amplifier devices for each student's desk be of the same general type. According to the present invention, an acoustic engineer uses a sound measuring device equipped with an amplifier of the same design as an amplifier installed on a student's desk to individually adjust the adjustment elements to suit the degree of hearing impairment of a hearing-impaired person. can be adjusted.

場合がある。Furthermore, each adjustment element, for example a potentiometer, can be marked with a number indicating the adjustment state of the adjustment element. If the numbers attached to the various adjustment elements are in a specific arrangement, this becomes the identification number for the hearing-impaired person. Because the acoustic characteristics of headphones vary significantly, adjustment to the degree of hearing impairment of a hearing impaired person (by appropriate adjustment of the adjustment elements) may only be possible with a particular headphone.

In this case, the plug-in unit remains connected to the headphone, which has been adjusted to suit the degree of hearing impairment. Therefore, when the student moves, he carries the headphone along with the headphone connection to the next student's desk.
In that case, each adjustment element accommodated in the plug-in unit,
For example, the headphone connection must be provided with a large number of contact pins so that the adjustment element for automatic gain control and the headphone connection can each be connected to the amplifier. The invention will be explained with reference to embodiments shown in the drawings.
