FIELD: physics, clock.
SUBSTANCE: invention relates to electronic alarm clock. Touch-sensitive alarm clock has case (20), vibration pickup (22) mechanically connected with said case to perceive the impact when the user touches said case and control circuit (24) connected with vibration pickup for alarm clock function control. Audio unit (26) is connected with sound generation audio circuit (25), for example, loudspeaker in alarm clock or awaking light source. To avoid sound and vibration pickup interferences claimed alarm clock incorporates filter (23) connected with vibration pickup and control circuit. Filter features filtration curve corresponding to set of frequencies existing in the sound.
EFFECT: possibility to prevent function activation by sound frequencies while the pickup perceives the other frequencies approximating to sound frequency range for reliable perception of the touch.
