<p>PROBLEM TO BE SOLVED: To provide a punch sound sensing device by which a user can sense the sound of punches when shaking fists, so that the user can get rid of stress. SOLUTION: This punch sound sensing device consists of a band 1a to be put around a user's arm and a case 2 attached to the band 1a. An acceleration sensor 4, a sound source 5, and a power source 6, which are connected by circuits, are housed in the case 2. The acceleration sensed by the acceleration sensor 4 is converted to the quantity of electricity, and a volume of electricity in proportion to the quantity obtained by the acceleration sensor 4 is sent to the sound source 5 by way of the circuit. And a volume of sound is proportion to the quantity of electricity sent through the circuit is outputted from the sound source 5. The sound is controlled by a power switch 11 and an operation part 8a arranged facing the outside of the case 2, of a volume controller 8 which controls the volume of sound outputted from the sound source 5.</p> |
