    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: An imaging apparatus includes: an image sensor that captures a subject image to generate image data; an audio processor that generates audio data associated with the image data; and a receiver that receives a first audio signal and a second audio signal from an external sound collection apparatus. The first audio signal indicates a result of first amplification conversion performed on input sound in the sound collection apparatus. The second audio signal indicates a result of second amplification conversion performed on the input sound in the sound collection apparatus, the second amplification conversion being different from the first amplification conversion. The audio processor performs processing to combine the first and second audio signals, which received from the receiver as input, with each other, to generate the audio data of a sound collection result indicating the input sound in a predetermined data format.

    摘要: A loudspeaker including: a diaphragm having a first radiating surface and a second radiating surface, wherein the first radiating surface and the second radiating surface are located on opposite faces of the diaphragm; a drive unit configured to move the diaphragm based on an electrical signal; a loudspeaker support structure, wherein the diaphragm is suspended from the loudspeaker support structure via one or more loudspeaker suspension elements. The loudspeaker support structure comprises a self-supporting porous shell which encloses a volume configured to receive sound produced by the second radiating surface, wherein at least part of the self-supporting porous shell is provided by at least one self-supporting portion of porous material having a specific airflow resistance in the range 500-10000 Pa·s/m so as to allow sound produced by the second radiating surface to exit the volume enclosed by the shell.
