Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] see figure 1 , is a structural diagram of a hearing aid that can be rotatably adjusted for volume provided by an embodiment of the present invention. The hearing aid includes an earphone, and the earphone includes a first shell 1 constituting the body of the earphone and a second shell 2 constituting the head of the earphone. The first shell There is a cavity between the body 1 and the second housing 2 , and a main board 3 is fixedly arranged in the cavity, and the main board 3 is provided with an MCU 4 and a potentiometer 5 .

[0034] The main board 3 is also provided with other functional...

Abstract

The invention is applicable to the technical field of hearing assistance. The invention provides a hearing aid capable of rotatably adjusting volume and a volume adjusting method. The hearing aid comprises an earphone. The earphone comprises a housing. An MCU and a potentiometer are arranged in the shell. The shell is provided with a knob fixing shell. The knob fixing shell is sleeved with a knobrotating shaft, the rotating shaft is provided with a cross-shaped protrusion. The cross-shaped protrusion is rotationally connected with a volume adjuster. The volume adjuster comprises a rotating part and a fixing part. The rotating part is connected with the cross-shaped protrusion in a matched mode. The fixing part is provided with a welding spot. One end of the welding spot is electrically connected with the potentiometer, and the other end of the welding spot is electrically connected with the rotating part. When the volume adjusting device is used, the knob is rotated, the knob drives the rotating part to rotate through the cross-shaped bulge on the rotating shaft, so that the resistance of the volume adjuster is changed, the potentiometer converts the resistance change into a voltage change signal, the voltage change signal is transmitted to the MCU, and the MCU adjusts the volume of the hearing aid according to the voltage change signal. The device is small in size, attractiveand convenient for old patients to operate.

Description

technical field [0001] The invention belongs to the technical field of hearing aids, and in particular relates to a hearing aid capable of rotating and adjusting the volume and a volume adjustment method. Background technique [0002] A hearing aid is a small loudspeaker that amplifies the originally inaudible sound, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain, so that the sound can be felt. [0003] Existing hearing aids are equipped with additional buttons on the surface of the earphone for volume adjustment. When in use, the volume can be adjusted by pressing or touching the buttons. [0004] However, due to the miniaturization of hearing aids, the volume buttons also need to be designed smaller and smaller, which is not easy for hearing patients, especially elderly patients, to operate. In addition, disposing additional buttons on the surface of the hearing aid also affects the overall aesthetics of th...
