Abstract

The invention provides an ear muffle and a helmet adopting the same. The ear muffle comprises a sheath; the sheath is provided with a first surface and a second surface which are arranged oppositely;a groove fit with a human ear is formed in the first surface; the sheath is a protein leather sheath and has a hollow structure; a soft pad, a liner, a sealing pad and an ear casing are arranged in the sheath; the soft pad and the liner are annularly distributed in the sheath; the soft pad is arranged near the first surface; the soft pad is a silicon phosphorus ester soft pad; the liner is arranged near the second surface; the soft pad is contacted with the liner; the sealing pad is arranged on the bottom surface of the first surface; the sealing pad is connected with the annular soft pad; theear casing is arranged in an accommodating space which is formed by the sealing pad, the soft pad and the liner in an enclosing way, and is wrapped by the sealing pad, the soft pad and the liner; theear casing and the sealing pad form a semi-circular accommodating cavity in an enclosing way; the accommodating cavity is used for accommodating the human ear; and a sound signal transmission deviceis arranged in the ear casing. The ear muffle can solve the problems of low wearing comfortability and low sound leakage resistance in the prior art.

Description

technical field [0001] The invention relates to the technical field of helmets, in particular to an earmuff and a helmet using the earmuff. Background technique [0002] Helmets are widely used in daily life and military fields. At present, in various types of helmet equipment, a large number of receivers are used for sound signal transmission. When the helmet and receiver are installed and used together, there are more It is bonded to the helmet body through glue or nylon velcro, and the other side is closely attached to the face and ears of the personnel. [0003] Since the structural parts of the handset are mostly made of hard materials, in order to alleviate the discomfort caused by the hard materials on the face of the personnel and prevent the sound leakage caused by the loose fit between the head-mounted handset and the face, usually the handset and the handset Design and install flexible earmuffs on the contact parts of the personnel's face to solve the above probl...
