Abstract
A human wearable mask includes a skirt for directly contacting a human wearer and a sound conduction component on the skirt. The sound conduction component can provide an alert notification within high-noise environments while allowing ambient sounds to be heard over the conduction speakers. The sound conduction component may be used to reproduce audio for firefighters and other users who need radio communications.
Claims20
A human wearable mask comprising:
- a skirt for contacting a skull bone of a human wearer, the skirt including:
- a sound conductive vibration element in contact with the skirt, wherein the sound conductive vibration element is positioned in contact with the skirt to conduct sound to the skull bone.
An air purifying respirator comprising:
- at least one air purifying cartridge;
- an end of service life indicator to detect a cartridge end of service life and generate an electronic alert signal;
- a transducer communicatively coupled to the end of service life indicator to convert the electronic alert signal into a vibration signal;
- a skirt for contacting a skull bone of a human wearer;
- and
- a sound conductive vibration element communicatively coupled to the transducer and in contact with the skirt, wherein the sound conductive vibration element converts the vibration signal into an audible vibration, and wherein the vibration element is arranged to conduct the audible vibration to the skull bone.
3 more elements
A method comprising:
- obtaining an electrical signal representative of information to be communicated to a wearer of a mask;
- converting the electrical signal to sound conductive vibrations;
- and
- transferring the sound conductive vibrations to a skull bone of the wearer of the mask such that the information is audibly provided to the user via the vibrations of the skull bone.
