    摘要： A speaker includes a telescopic sound chamber, a first diaphragm, and a first piezoelectric vibrating element. The telescopic sound chamber has a box wall, a bottom layer, and a first opening. The telescopic sound chamber includes a plurality of telescopic sub-box layers sleeved on and connected to each other and decreasing in volume layer by layer. The telescopic sound chamber accommodates the smaller telescopic sub-box layer into the larger telescopic sub-box layer to reduce the volume of the telescopic sound chamber. The telescopic sound chamber moves the smaller telescopic sub-box layer away from the larger telescopic sub-box layer to increase the volume of the telescopic sound chamber. The first diaphragm is arranged on the box wall to cover the first opening. The speaker can improve the drawbacks of low-frequency range distortion and has the advantages of full audio, high volume, and smooth sound pressure.

    摘要： A radio receiver apparatus comprises radio circuitry for receiving a sequence of radio data packets, transmitted at regular intervals, wherein the sequence of radio data packets encodes a digital audio stream and each radio data packet encodes a respective number of audio samples from the digital audio stream. The apparatus also comprises a digital audio interface for outputting audio samples from the received digital audio stream, a controllable oscillator arranged to control an output rate at which the audio samples are output from the digital audio interface, and a timer. The apparatus also comprises control logic, configured to use the timer to measure an interval between receiving each of a pair of the radio data packets, and to control the oscillator to vary the output rate incrementally, in a number of steps, while outputting the audio samples from one radio data packet. The number of steps, or the size of each step, or both, depends on the measured interval.
