FIELD: physics.
SUBSTANCE: inter-channel earpiece contains at least three electro-acoustic transducers installed in the casing. The body is designed to be located in the external auditory canal. The front part of the case, when using the earpiece, is located in the region of the second turn of the external ear canal. The first electroacoustic transducer is installed in the front of the casing, the other electroacoustic transducers are installed along the length of the casing and are equipped with coaxial acoustic channels, the outputs of which are located in the front part of the casing. The front part of the body is teardrop shaped with the corresponding typical ear canal expansion and is equipped with a flexible sealing nozzle. The electroacoustic transducers have a balanced armature, the flexible sealing nozzle is made of silicone and is deployed upwards relative to the body axis by an angle of 5-20°.
EFFECT: improvement of the design of the machine.
