A headset, a circuit structure of a mobile apparatus, and a mobile apparatus are provided. The headset includes at least one earphone, a microphone, an audio plug, and a headset cable. The audio plug includes a connector having a plurality of contacts. The microphone and the at least one earphone is coupled to the corresponding contacts of the audio plug through the headset cable. The headset cable includes a ground line, a microphone line, at least one audio line, and an antenna for receiving a television broadcasting signal. The antenna is coupled to one of the contacts coupled to the ground line, the microphone line, and the at least one audio line. The one of the contacts to which the antenna is coupled further serves as a radio frequency contact to provide the television broadcasting signal and an audio broadcasting signal.

Headset, circuit structure of mobile apparatus, and mobile apparatus

According to one embodiment, a management circuit for a portable device includes an input terminal, a first step-up converter, a first step-down converter, and a second step-down converter. The input terminal is coupled to receive a supply voltage from a power supply. The first step-up converter, coupled to the input terminal, selectively converts the supply voltage to a boosted voltage. The first step-down converter, coupled to the first step-up converter, selectively provides a first output power voltage to a first radio frequency (RF) module. The second step-down converter, coupled to the first step-up converter, selectively provides a second output power voltage to a second radio frequency (RF) module. The first step-up converter performs the conversion of the supply voltage when the supply voltage is under a threshold voltage.

System power integrated circuit and architecture, management circuit, power supply arrangement, and portable apparatus

A portable device is provided. The portable device comprises a first wireless module, a second wireless module, a first subscriber identity card coupled to the first wireless module, a second subscriber identity card coupled to the second wireless module and a battery. The first subscriber identity card camps on a cell via the first wireless module. The second subscriber identity card camps on the same cell or a different cell via the second wireless module. A first transmission power of one of the first and second wireless modules is maintained, and a second transmission power of another one of the first and second wireless modules is dynamically adjusted according to a variation in a voltage of the battery.

Portable device with subscriber identity cards and method for controlling transmission power thereof

A portable device and method thereof are disclosed. The method includes recognizing a mode of the portable terminal; monitoring a sensitivity corresponding to an antenna of the portable terminal; sensing a movement corresponding to the portable terminal; invoking an application when both of following conditions occur: a degradation of the sensitivity is determined; and the movement exceeding a predetermined displacement is determined.
