Abstract
A speaker includes a hollow casing, a vibration plate, a vibrator, a wireless communication unit, and a processor. The casing defines a receiving space. The vibration plate is secured to the casing, and includes a first portion received in the receiving space and a second portion protruding out of the casing. The vibrator is received in the receiving space and attached to the first portion. The processor is configured to control the vibrator to vibrate when the speaker receives a wireless signal via the wireless communication unit, thereby allowing the vibration plate to vibrate and output sound.
