Problems solved by technology

However, because the muscle tissue of the ear canal is very soft, it is not easy to converge when vibrating, especially low-frequency vibrations can cause long-term tremors in the muscle tissue, so the vibration waves in the muscle tissue will have a superimposed effect similar to echoes in the time domain, causing voice signals turbidity, decreased speech intelligibility
In addition, because the muscle tissue is very soft, it has a greater attenuation to high-frequency vibrations, which is another reason why the voice clarity of ear canal contact microphones is not high.

Abstract

The invention discloses an in-ear headset, which relates to the technical field of audio equipment and solves the technical problem of improving voice intelligibility. The headset comprises a shell, an earplug, and a loudspeaker as well as a contact microphone respectively mounted in the shell; sound holes are formed on the shell, the inner end of the shell is cylindrical, a slot is arranged in the shell, and the contact microphone is inserted in the slot in a manner of interference; the earplug is composed of a soft ear muff, and a soft inner tube fixed in the ear muff; and the inner end of the shell is inserted in the inner tube of the ear muff in a manner of interference. The in-ear headset is characterized in that the earplug is provided with a soft O-shaped ring, and the inner end of the shell passes through the center of the O-shaped ring. The headset provided by the invention has high voice intelligibility.

Description

technical field [0001] The invention relates to audio equipment technology, in particular to an in-ear headset technology. Background technique [0002] In-ear headsets are equipped with a speaker and a contact microphone in the casing, and a sound hole is opened on the casing, so that the sound from the speaker can be transmitted to the ear canal. The contact microphone is in contact with the muscle tissue of the human ear canal, picking up The vibration of the skull and muscle tissue when a person makes a sound is converted into an electrical signal, thereby realizing voice transmission. However, because the muscle tissue of the ear canal is very soft, it is not easy to converge when vibrating, especially low-frequency vibrations can cause long-term tremors in the muscle tissue, so the vibration waves in the muscle tissue will have a superimposed effect similar to echoes in the time domain, causing voice signals The turbidity and the decrease of speech intelligibility. I...
