Problems solved by technology

Although this technology can meet the basic functional requirements, the accuracy is not high, and because the stimulation frequency otoacoustic emission signals that the time domain and frequency domain to be collected by this technology overlap with the stimulation sound are very weak, the noise of the existing equipment is too high. Large, affecting the accuracy of the test results

Abstract

The invention relates to a microphone and loudspeaker integrated system, and the system comprises a loudspeaker assembly which is used for converting an inputted audio electronic signal into a stimulation sound signal; a otoacoustic emission probe comprising a shell, an earphone sound guide pipe and a miniature microphone, aminiature microphone used for detecting an acoustic signal in a human earand converting the acoustic signal into an electric signal, and a microphone conditioner assembly used for conditioning the electric signal detected in the ear; and the earphone sound guide pipe and the miniature microphone are arranged in the shell, one end of the earphone sound guide pipe is connected with the loudspeaker assembly, and the other end of the earphone sound guide pipe penetrates out of the shell and is used for transmitting stimulation sound signals into ears. The precision can be improved, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical fields of electronics and signal processing, in particular to a microphone and loudspeaker integrated system. Background technique [0002] The microphone is an electro-acoustic device that can convert acoustic signals into electrical signals. Its working principle is that the electro-acoustic components vibrate under the action of sound waves to generate voltage. Microphones are mostly used in various sound amplification equipment, and are mainly divided into dynamic microphones and condenser microphones according to the energy conversion method. Among them, the principle of the dynamic microphone is to generate electrical signals through the movement of the conductor in the magnetic field, and the vibration of the coil driven by the diaphragm causes the coil in the magnetic field to generate an induced current. The diaphragm capacitance of a condenser microphone is an electrode of a capacitor. When the diaphrag...
