Abstract: Embodiments of the present invention disclose an audio play apparatus and a device. The audio play apparatus includes a loudspeaker, a loudspeaker container, and a cavity expansion material, where the loudspeaker and the cavity expansion material are disposed in the loudspeaker container, the cavity expansion material is a fabric made of fibers with irregular holes on a surface, and holes are formed between fibers of the fabric. The fabric made of the fibers with the irregular holes on the surface is disposed in the audio play apparatus. In this way, when the audio play apparatus plays audio, by using gaps between the fibers of the fabric and the irregular holes on the surface of the fibers, a resonance frequency f0 of the audio play apparatus is reduced, and a frequency band width is increased.
