  • Publication number: 20040203414
    Abstract: A wearable electronic device is offered in which sound radiation and sound reception operations of an electroacoustic converter are performed reliably. The wearable electronic device can be a personal digital assistant (PDA) having an enclosure portion that is worn on a user's wrist in use. The electroacoustic converter is incorporated in the enclosure portion. Sound radiation and reception holes extending through the wall of the enclosure portion are formed between the inner surface and the outer surface of the enclosure portion. The inner surface surrounds the converter, while the outer surface makes contact with the user's wrist when the device is worn. The enclosure portion has recessed or convex portions on or in portions of the outer surface around the openings of the sound radiation and reception holes to form acoustic signal propagation paths.
