    Abstract: A speaker structure includes a speaker box, a speaker unit, and an elastic component. An air pressure inside the speaker box is lower than that outside the speaker box. The speaker unit is disposed on the speaker box and includes a first vibrating assembly. The elastic component is disposed in the speaker box and connected to the first vibrating assembly and the speaker box in the speaker unit. When the speaker unit operates, the first vibrating assembly of the speaker unit vibrates, and the elastic component produces a pre-force correspondingly, the total pressure of the pre-force and the air pressure inside the speaker box equals to the air pressure outside the speaker box to balance the first vibrating assembly at an equilibrium position.

    Abstract: A wearable communication device includes an annular shell, a processing module, a first piezoelectric unit, and a driving unit. A cavity is formed at a part of the annular shell. The processing module processes communication data. The first piezoelectric unit is disposed in the cavity. The driving unit is used to receive the communication data and drive the first piezoelectric unit according to the communication data to make the first piezoelectric unit vibrate and trigger a corresponding audio signal. The wearable communication device can be wirelessly connected to an electronic device without physical wires to improve the convenience greatly.
