Abstract
The present invention provides an arm-wear-type communication device for protecting a speaker and the like. In an arm-wear-type communication device, a speaker is equipped on a housing that is a portion fitting to an ear. After this speaker is matched into a cavity of the housing, the speaker is embedded by a housing cover. After the speaker is installed, a sound opening equipped for connecting the inside of the housing with the outside of the housing is equipped by boring as a sound emitting opening on the housing cover. An air chamber formed by the housing cover is equipped immediately in front of a sound emitting portion of the speaker. Further, on the back surface of the housing cover, a waterproof sheet is stuck to protect infiltration of rain, sweat or the like into the speaker. The housing cover engages with a cushion including a sound communication opening equipped at a different position from the position where the sound opening is extended approximately in a vertical direction to the outside with respect to the housing.
