  • Patent number: 7242970
    Abstract: The present invention is a Bluetooth™ hands-free kit structure. After the hands-free module according to the present invention executes Bluetooth™ functional pairing with a Bluetooth™-equipped mobile phone, it can be used as a acoustic type hands-free muting system device of Bluetooth™-equipped mobile phone which employs acoustic speakers as its audio output, or can be used as a Bluetooth™-equipped hands-free kit which employs a loudspeaker as its audio output, and also can be used as a Bluetooth™ earphone by itself. The Bluetooth™ hands-free kit structure can be expanded to have both charging and Bluetooth™-functions, and also can be a module structure with private communication switch capability.

  • Publication number: 20010006905
    Abstract: A hands-free cellular telephone base includes a privacy switch unit having a contact switch and a spring-biased switch actuator. The contact switch is mounted in a housing and is operable to control operation of a control circuit unit between a privacy mode and a broadcast mode. The switch actuator is mounted movably on the housing and is movable from a normal position, where the switch actuator does not actuate the contact switch for operation in the privacy mode, and a pressed position, where the switch actuator actuates the contact switch for operation in the broadcast mode. A magnet member is disposed in the housing such that, when an earphone is disposed adjacent to the switch actuator, the magnet member will attract with the earphone, thereby forcing the switch actuator to the pressed position against biasing action of the spring.

  • Patent number: 5802167
    Abstract: A hands-free device is adapted for use with a cellular telephone in a car to permit hands-free operation of the cellular telephone, and includes a main terminal, a secondary terminal, and a microphone provided on one of the main and secondary terminals. The main terminal includes a first casing, a power supplying unit, a voltage regulating circuit, a first connector, an audio output amplifier circuit, and a sound output unit. The secondary terminal includes a second casing, a second connector connected removably to the first connector, a third connector connected removably to the cellular telephone, a hands-free control circuit, a voltage output control circuit, and a gain control circuit. The secondary terminal can be replaced so that the hands-free device can be used with any type of cellular telephone without changing the main terminal.

  • Patent number: 5613659
    Abstract: A suction device includes a suction cup and a flexible hanging member attached to the suction cup. The suction cup has a pivot unit projecting integrally therefrom and a periphery located in a plane which is spaced from the pivot unit at a predetermined distance. The hanging member includes a socket unit which receives rotatably the pivot unit therein and which exposes the suction cup to an exterior of the socket unit, and a plurality of pressing claws connected securely to the socket unit. Each of the pressing claws has a planar abutting surface which is substantially parallel to the plane and which is spaced apart from the pivot unit at a distance that is larger than the predetermined distance. The socket unit is generally U-shaped and is provided with a pair of tongues which permit entry of the pivot unit into the socket unit and which prevents removal of the pivot unit therefrom.
