AI Technical Summary

Technical Problem

Existing pure tone sounders used for hearing testing have problems with poor convenience and poor stability, especially when being moved and placed, they are easily affected by the levelness and inertia of the ground.

Method used

The pure tone sounder is moved and positioned using servo motors, bevel gears, screw barrels and other structures, and stability and convenience are improved through stabilizing mechanisms, lubricating mechanisms and auxiliary mechanisms, including adsorption plates, support tiles, lubricating oil and other structures to ensure stable placement and lubrication. The auxiliary mechanism clamps the sound-transmitting earphone through a fan and a support plate to improve its stability.

Benefits of technology

The position of the pure tone sounder is adaptively adjusted and stabilized, which improves the convenience of use, ensures the stable placement of the sound-transmitting earphone, reduces hard wear and improves the overall operating state.

Abstract

The pure tone sounder comprises a base, the upper end of the base is fixedly connected with a supporting frame, the base and the supporting frame are jointly provided with a stabilizing mechanism, the upper end of the supporting frame is fixedly connected with a fixing frame, the horizontal portion of the fixing frame is rotationally connected with a stud, and the stud is fixedly connected with a fixing base. The stud makes contact with the horizontal part of the supporting frame, and the outer side of the stud is fixedly sleeved with a first bevel gear. The invention relates to a pure tone sounder for hearing detection, which has the function of assisting in stabilizing the integral structure of the pure tone sounder so as to avoid the problem of additional movement of the pure tone sounder, and can adaptively adjust the position of the pure tone sounder so as to improve the use convenience of an operator. And an idle sound transmission earphone can be hooked and fixed for use, so that the stability of the sound transmission earphone is ensured.
