Description

Otoacoustic emission instrument probe Technical Field The invention belongs to the technical field of hearing devices, and relates to an otoacoustic emission instrument probe. Background Otoacoustic emission devices are electronic devices that quantitatively detect the extent of hearing loss by generating pure tone signals of varying frequencies and intensities, in combination with subjective feedback from the patient. The current otoacoustic emission instrument probe internal component layout lacks systematic design that a circuit board, a loudspeaker and a microphone are stacked in a shell in a scattered manner, and no reasonable space planning and fixing are performed. During screening, the probe of the otoacoustic emission instrument is plugged into the auditory canal of the newborn, but the head of the newborn shakes or the limbs are moved, so that the whole instrument is stressed unevenly. Because the internal components have no fixed structure, the contact pressure fluctuation between the probe and the auditory canal can be further amplified due to the gravity center deviation of the instrument, the probe is easy to shift or fall off, the wearing position is required to be adjusted repeatedly, and the screening efficiency is obviously reduced. In addition, the scattered wires of the existing otoacoustic emission instrument probes form a clutter loop in the shell, and the loudspeaker and the electromagnetic sensitive elements such as a microphone are lack of shielding and isolation. During screening, the probe is required to be close to the auditory canal, electromagnetic noise is easy to interfere with a test signal through spatial coupling or a lead, so that the problems of data distortion such as fluctuation of acoustic immittance measured value, threshold judgment deviation and the like are caused, and screening failure is directly caused when the problems are serious. Therefore, there is a need to develop a hearing screening instrument probe that is uniform in weight and has little signal interference.
