Adjustable audiometry headset mounting system

Abstract

The invention discloses an adjustable audiometry earphone mounting system that comprises a bone conduction earphone support and an air conduction earphone support, and further comprises a bone oscillator, an installation piece and an adjusting mechanism; one end of the bone conduction earphone support is installed on the air conduction earphone support, the installation piece is installed at the other end of the bone conduction earphone support, and the bone oscillator is movably installed on the installation piece through the adjusting mechanism. The mounting system disclosed by the inventioncan be mounted on various air conduction earphone brackets, can be disassembled and assembled, and is convenient to carry. In actual use, a subject only needs to wear the air conduction earphone instead of wearing two head hoops at the same time, use is convenient, and comfort is improved. The mounting system is provided with the adjusting mechanism used for adjusting the position of the bone oscillator, the bone oscillator can be adjusted at any time, then control over the contact pressure between the bone oscillator and the skin of the human body is achieved, the contact pressure with the most suitable strength is obtained, and the comfort degree and the audiometry efficiency are improved.

Description

technical field [0001] The invention relates to the field of hearing equipment, in particular to an adjustable audiometry earphone installation system. Background technique [0002] Bone conduction audiometry is a very important item in hearing function testing, and it is also one of the basic audiological examination items. Bone conduction audiometry is relatively complicated. The existing test methods are cumbersome, time-consuming, and have many mistakes. This is mainly caused by two reasons: First, the bone conduction test method requires the subject to wear air conduction earphones and bone conduction earphones at the same time. The headband adopts a leaf spring, and the two headbands cannot touch to avoid cross-conduction of vibration and additional noise caused by friction between the two. Usually, the vibrator of the bone conduction earphone needs to be placed on the mastoid or the forehead, and the contact pressure with the skin should not be lower than 500 grams. ...

Bone conduction audiometry is relatively complicated. The existing test methods are cumbersome, time-consuming, and have many mistakes. This is mainly caused by two reasons: First, the bone conduction test method requires the subject to wear air conduction earphones and bone conduction earphones at the same time. The headband adopts a leaf spring, and the two headbands cannot touch to avoid cross-conduction of vibration and additional noise caused by friction between the two

Usually, the vibrator of the bone conduction earphone needs to be placed on the mastoid or the forehead, and the contact pressure with the skin should not be lower than 500 grams. This pressure control is controlled by the leaf spring of the headband of the earphone, and the pressure control is not accurate (different head shapes, different pressures, The pressure is different, the vibration conduction of the bone vibrator is different), and, during the test, the bone conduction earphone will slide, and the vibration cannot be transmitted accurately or the vibration is changed during the test. This leads to deviations in the results; the second is that the subject wears two earphones at the same time, and the two headbands are buckled on the head, which makes the comfort type poor.
