Bone conduction fire fighting helmet

Abstract

The invention discloses a bone conduction fire fighting helmet which comprises a helmet body and a mask, wherein the mask is connected to the front end of the helmet body, a visual window is arranged on the mask, a fixing ring is arranged inside the helmet body, and a bone conduction earphone is pasted to the fixing ring by a hook-and-loop fastener; a bone conduction vibrator is arranged at the end part of the bone conduction earphone, and the outside of the bone conduction vibrator is wrapped with a shell; the bone conduction vibrator comprises a metal sheet, piezoelectric ceramic pieces are attached to the two end surfaces of the metal sheet respectively, the polarities of the piezoelectric ceramic pieces are opposite, and plastic layers are arranged on the surfaces of the piezoelectric ceramic pieces; a microphone is arranged on the helmet in the position corresponding to the mouth part of a user. According to the bone conduction fire fighting helmet, the structure is reasonable, the mounting is convenient, the bone conduction earphone is not required to be inserted into the ear, control of the spot is not affected while the earphone is used, clear conversation of communication under the high-noise environment is realized, a rescue worker can receive the command timely, rescue work can be performed effectively, and the purpose of high noise resistance is realized.

Description

technical field [0001] The invention relates to a helmet, in particular to a bone conduction firefighting helmet. Background technique [0002] Helmets are specially designed to protect a person's head. It protects against sudden blows, flying debris, particles, low-voltage electric shock, or any combination of these three hazards, while also protecting against acid, other chemicals, or hot liquids being poured overhead Plays the role of protecting the head, face and neck. It should be said that helmets play a vital role in protecting people's head safety in dangerous situations. [0003] However, traditional safety helmets can no longer meet the requirements of the times. The existing helmets have the following disadvantages: the non-detachable intercom equipment limits its application range, the microphone device easily causes head discomfort, and the position of the earphone cannot be adjusted.
