  • Publication number: 20230276154
    Abstract: A magnetically attractable Bluetooth speaker is disclosed, including a speaker housing, a loudspeaker, a control circuit board, and a magnet. The loudspeaker is electrically connected to the control circuit board. The speaker housing includes a limiting part for securing the magnet. The magnet is fixedly arranged in the limiting part, and the magnet is arranged outside the magnetic circuit range of the loudspeaker. With such a structure, by arranging the magnet in the speaker housing, the user experience of the speaker can be greatly improved, so that the user can place it in different manners depending on their different needs. Compared with the traditional ordinary speakers that can only be placed on a horizontal plane or a surface with a small slope, the speaker provided by the present disclosure has better flexibility in use.

  • Patent number: 8666422
    Abstract: An access point for supporting communication in a femto cell of a cellular communication network. The access point comprises transceiver circuitry arranged to enable communication with at least one cell subscribed wireless communication unit located within the femto cell, and signal processing logic module. The signal processing logic is arranged to configure a transmit power level of a Common Pilot CHannel (CPICH) for transmission based at least on cell subscribed wireless communication unit information.
