Embodiment Construction

[0014] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0015] Such as figure 1 , 2 As shown, a bone conduction earphone detection device includes a hard balance base 1, and a box body 3 is supported on the hard balance base 1 by a vibration damping spring 2. The box body 3 has a hollow cylindrical structure, and the vibration damping spring 2 is set There are three, and the three damping springs 2 are evenly distributed along the bottom edge of the box body 3 . The box body 3 is provided with a detection plate 5 supported by a buffer spring 4. The detection plate 5 is disc-shaped. There are three buffer springs 4, and the three buffer springs 4 are evenly distributed along the bottom edge of the detection plate 5. A vibration sensor 6 is provided at the center of the bottom of the detection plate 5 , and a detection contact point 7 for placing a bone conduction earphone is provided on the top surface...

Abstract

A bone conduction earphone detection device is characterized in that a box body is arranged on a hard balance base through a damper spring in a supporting manner, a detection flat plate is arranged on the box body through a buffer spring in a supporting manner, a vibration sensor is arranged at the bottom of the detection flat plate, a detection contact point is arranged on the top surface of the detection flat plate, and the vibration sensor is electrically connected with a signal interface; a first support is further fixed to the hard balance base, a second support is rotatably hinged to the first support, an elastic rubber band is arranged on the second support, the elastic rubber band can make contact with the detection contact point by rotating the second support, and a tension column is further fixed to the hard balance base. The tension column is connected with a tension spring in a position-adjustable mode through an adjusting knob, and the tension spring is connected with the second support. The detection device can reduce vibration signal errors and improve the problems of slow low-frequency response and low sensitivity, thereby improving the detection precision.

Description

technical field [0001] The invention relates to the technical field of hearing device detection, in particular to a bone conduction earphone detection device. Background technique [0002] At this stage, there is a kind of earphone through bone conduction. Bone conduction is a sound conduction method, that is, the sound is converted into mechanical vibrations of different frequencies, which are transmitted through the human skull, bone labyrinth, inner ear lymph, screw, auditory nerve, and hearing. Center to transmit sound waves. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission, and can achieve clear sound reproduction in noisy environments. Due to the particularity of the sound conduction method of bone conduction earphones, it generally does not cause damage to the auditory parts such as the outer ear used to collect sound and the tympanic membrane and ossicles th...
