Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 1, the currently used head-worn bone conduction earphone in the clinical pure-tone hearing test process is arc-shaped, one end is an active bone vibrator 7, the other end is a fixing part 5, and the middle is connected by an iron head band 6. In use, the bone vibrator 7 is placed on the mastoid bone behind the ear of the subject, and the part is vibrated to directly transmit sound information to the inner ear through the skull. However, since the head shape and the papilla shape of different subjects are significantly different from one another, the papilla portion is affected by the hair to a different extent, and thus the bone oscillator 7 is likely to slip off or shift from the papilla in actual operation.
In order to reduce the emergence of bone oscillator from mastoid department slippage phenomenon when hearing test, the utility model provides a bone conduction headset with bandeau altitude mixture control support, bandeau altitude mixture control support includes: the bracket comprises a bracket main body, wherein a plurality of head band limiting parts with different heights are arranged in the bracket main body; in the using state, the headband height adjusting support is placed on the top of the head of a subject, the headband penetrates through one of the headband limiting parts, and the wearing height of the headband is adjusted by placing the headband into the headband limiting parts with different heights. The utility model discloses an adjust wearing of bandeau highly, adjust wearing of bone oscillator highly, make the height of bone oscillator and the highly roughly the same of testee mastoid to prevent that the bone oscillator from locating the slippage from mastoid in hearing test process.
