Abstract
A foldable handy phone of the present invention includes a receiver case and a transmitter case hinged to each other. A piezoelectric device or similar sounding means is accommodated in the receiver case. A through hole is formed in the surface of the receiver case that faces the transmitter case when the handy phone is folded up. The through hole is communicated to a portion accommodating the sounding means. A groove is formed in the above surface of the receiver case and extends from the open end of the through hole to the end of the receiver case opposite to the end hinged to the transmitter case. When the sounding means produces an alert tone in the folded position of the handy phone, the alert tone is radiated to the outside via the groove.
