  • Patent number: 8031059
    Abstract: A system (100) for communicating multimedia messages includes a multimedia message server (102) that is operable to transmit (1404, 1406, 1408) visual media, a vibration melody (1200), and an audio segment (1300) that is preferably filtered (1402) to exclude frequencies of the vibration melody (1200) through a network (104) to a client device (106), and is operable to, preferably at a later time, to transmit instructions (1410) to the client device (106) to output the vibration melody (1200), audio segment (1300) and visual media. At the client device, (106) the audio segment (1300) and the vibration melody (1200) and visual media are preferably stored (1504, 1508, 1512) in a memory (608) and in response to the instruction signal are read (1616, 1518, 1520) from the memory (608), decoded (1522, 1524, 1526) and output (1528, 1530, 1532) to a user. The vibration melody (1200) and the audio segment (1300) are preferably applied at least partially concurrently applied to an electromechanical transducer (212).

  • Publication number: 20040203503
    Abstract: A portable electronic apparatus (100, 1000) includes a housing wall (116, 516, 916, 1012), and a piezoelectric transducer (118) unitized with the housing wall (116, 516, 916, 1012). The housing wall (116, 516, 1012) can be overmolded with the piezoelectric transducer (118) or the piezoelectric transducer (118) can be bonded to the wall (916). The portable electronic apparatus can for example comprise a watch (100) or a wireless communication device (1000). The piezoelectric transducer (118) can be driven to vibrate so as to produce a perceptible tactile or audible alert. The geometry of the piezoelectric transducer (118) and the manner in which it is integrated with the electronic apparatus (100, 1000) are such that only a small volume is required to accommodate the piezoelectric transducer (118).

  • Patent number: 6710518
    Abstract: An electronic device such a telephone (100), PDA (600), or pager (800), includes a manually operable input such as an elastomeric key (102, 103) or button (814), or a touch screen (604) that does not by itself provide substantial tactile feedback upon actuation, and also includes an electromechanical transducer (212) that is capable of generating an impulse of mechanical energy that can be felt. In response to detecting actuation of the manually operable input (102, 103, 814, 604), the electromechanical transducer (212) is driven to produce an impulse of mechanical energy that propagates to the manually operable input (102, 103, 814, 604) and provides tactile feedback to a user.

  • Publication number: 20040000877
    Abstract: An ASIC (138) that is useful in electronic devices that include a piezoelectric transducer (112), and an electroluminescent lamp (130), includes a DC to DC converter (402), a piezoelectric drive signal input (424), a piezoelectric transducer drive amplifier (404), an oscillator (406), and an electroluminescent drive amplifier (408). The DC to DC converter (402) boosts a voltage of an external power source (132) and powers the piezoelectric drive amplifier (404), and the electroluminescent drive amplifier (408). An externally supplied piezoelectric drive signal is input through the piezoelectric drive signal input (424) to a piezoelectric transducer drive amplifier input (426), and amplified. An amplified version of the signal is output on a pair of differential outputs (432). The electroluminescent drive amplifier (408) is driven by a signal generated by the oscillator (406).

  • Patent number: 6078126
    Abstract: A resonant piezoelectric alerting device (400) includes a motional mass (130) and a piezoelectric actuator (100) which is constrained to an actuator mount (132) at a first end and coupled to the motional mass (130) at a second end, the piezoelectric actuator and the motional mass in combination producing a resonant system having a predetermined frequency of operation. The piezoelectric actuator 9100) is responsive to a control signal (108, 110) generated at the predetermined frequency generates an alternating out-of-plane movement(812, 814) of said motional mass (130) which is transformed into tacile energy to provide a tactile alert about the resonant frequency (608). The out-of-plane movement (812, 814) of the motional mass (130) is also transformed into acoustic energy to provide an audible alert in response to a control signal generated above the predetermined frequency (608).

  • Patent number: 5945772
    Abstract: A damped resonant piezoelectric alerting device (600) includes a motional mass (130), a damping element (136, 156) magnetically coupled to the motional mass (130) and a piezoelectric actuator (100) which is constrained to an actuator mount (132) at a first end and coupled to the motional mass (130) at a second end. The piezoelectric actuator (100) responds to a control signal (108, 110) to generate an alternating out-of-plane movement (812, 814) of the motional mass (130) at an amplitude (412, 414). The alternating out-of-plane movement (812, 814) of the motional mass (130) is transformed into tactile energy to provide a tactile alert about a resonant frequency (608). The amplitude (412, 414) of the out-of-plane movement (812, 814) of the motional mass (130) is controlled by the damping element (136, 156). The alternating out-of-plane movement (812, 814) of the motional mass (130) is also transformed into acoustic energy to provide an audible alert above the resonant frequency (608).
