Vibration apparatus capable of generating and externally transmitting a sound wave of audible frequency and transmitting a vibration for notification

A vibration apparatus capable of generating and externally transmitting a sound wave of audible frequency and transmitting a vibration for notification, the apparatus comprising:

• a first vibrating section having an upper cover and a magnet secured to an inner surface of the upper cover;
• a fixed section having a fixed cover positioned below the upper cover and connected to the upper cover by a first elastic member, the fixed cover being formed at a center portion thereof with a sound discharging hole;
• a second vibrating section having a vibrating plate positioned above the fixed cover and connected to the fixed cover by a second elastic member and a pair of vibrating coils attached onto the vibrating plate;
• and
• a driving control section connected to both ends of each of the pair of vibrating coils of the second vibrating section, the driving control section allowing currents having the same polarity to flow to both ends of each of the pair of vibrating coils when a high frequency current for generating a sound wave is inputted therein and causing the second vibrating section to move up and down by electromagnetic force created between the pair of vibrating coils and the magnet of the first vibrating section thereby to enable a generated sound wave to be discharged through the sound discharging hole formed in the fixed cover of the fixed section, the driving control section allowing currents having different polarities to flow to both ends of each of the pair of vibrating coils when a low frequency current for generating a vibration is inputted therein and causing the first vibrating section to seesaw by electromagnetic force created between the pair of vibrating coils and the magnet of the first vibrating section thereby to generate a vibration.

A vibration apparatus capable of generating and externally transmitting a sound wave of audible frequency and transmitting a vibration for notification, the apparatus comprising:

• an outer case having an upper cover formed with a sound discharging hole, and a lower cover coupled to a lower end of the upper cover;
• a first vibrating section having a magnet positioned above the lower cover and connected to the lower cover by an elastic member, and a vertical shaft possessing a lower end connected to the lower cover and an upper end movably guiding the magnet;
• a second vibrating section having a vibrating plate possessing an edge portion secured to an inner surface of the upper cover at a place where the vibrating plate is opposite to an upper surface of the magnet, and a pair of vibrating coils attached onto a surface of the vibrating plate which faces the upper surface of the magnet;
• and
• a driving control section connected to both ends of each of the pair of vibrating coils of the second vibrating section, the driving control section allowing currents having the same polarity to flow to both ends of each of the pair of vibrating coils when a high frequency current for generating a sound wave is inputted therein and causing the second vibrating section to move up and down by electromagnetic force created between the pair of vibrating coils and the magnet thereby to enable a generated sound wave to be discharged through the sound discharging hole formed in the upper cover, the driving control section allowing currents having different polarities to flow to both ends of each of the pair of vibrating coils when a low frequency current for generating a vibration is inputted therein and causing the magnet of the first vibrating section to seesaw by electromagnetic force created between the pair of vibrating coils and the magnet thereby to generate a vibration as a seesaw motion of the magnet is transferred to the outer case through the elastic member and the vertical shaft.
