Abstract: A wireless mobile telephone capable of remitting picking up of an earphone in use-but combining with car hi-fi speakers, which mobile telephone applies an infrared transmission principle or a radio transmission principle to transmit its received and emitting signals to a car hi-fi set. Therefore, the car speakers can broadcast the sound of the other side of the mobile phone call in remitting picking up of the earphone. In this way, the mobile telephone not only has the advantage of remitting picking up of the earphone, but also can be extremely convenient in use by having no connecting wire between the mobile telephone and the car hi-fi set.

Abstract: A battery means for hand held electronic devices includes a device body with an elongated chamber which has an end opening and an elongated flange means, and an elongated battery packet moveable in the chamber through the end opening and is able to nest in the chamber securely because of the elongated flange means. The battery packet is an independent and self-contained unit houses a battery inside. The battery packet has a plurality of second contacts to couple with the battery and to engage with a plurality of first contacts located in the chamber to transmit electric power.

Abstract: Improved battery chamber contacts for handheld electronic devices include a plurality of longitudinally aligned and differently spaced battery contacts located on a lateral side of an elongated battery packet. The battery packet is housed in an elongated battery chamber in an electronic device. The battery chamber has chamber contacts mating and engageable with the battery contacts. Electronic coupling between the battery packet and the chamber will be established only when all mating contacts between the battery contacts and the chamber contacts are engaged.
