Description

  The present invention relates to a waterproof electric razor with a built-in sound generating means for voice display of charging prompts, remaining battery capacity, usage mode, and the like.

Japanese Patent Application Laid-Open No. 2004-151867 describes an idea of displaying the remaining capacity of a battery of a rechargeable electric razor by voice.
However, in the waterproof electric razor, in order to prevent water from entering the inside, a sealing material is interposed in the fitting portion between the members, and the screw portion is also provided with a packing to form a sealed structure. Therefore, even if a sound generation means for displaying sound is simply incorporated in the electric razor, the sound cannot be heard sufficiently by the user due to the sound generated inside.
