<p>PURPOSE:To provide a hole cup which can produce any other louder and rhythmical sound than a pleasant sound at a time of hole-in by installing inside the hole cup a sound device generating a large sound by sensing sound or vibration of a dropping ball. CONSTITUTION:A hole cup is assembled by a cup body 1, a ball receiver 3 and a sound device 5, all being disassemble. The sound device 5 is arranged on a calyx plate 23 fixed to a mounting stand 31 and formed of a speaker 25, a cell 27 to supply power to the speaker 25 and a sensor 29 to send an electric signal to an electric circuit. A sound collecting microphone is used as the sensor 29. When a ball drops down on a ball receiving plate 12, its dropping sound is sensed by the sensor 29, and at the same time, sent to an electric circuit where it is amplified. When a switch circuit is started, a voice circuit in the speaker 25 is operated to generate a voice in a chirp of birds which goes out of the speaker 25. Thus, even if the hole is too distant from a place where the ball is striken to hear the ball dropping sound, the sound thus amplified can be heard without fail.</p> |
