Abstract

A flexible wearable device includes a flexible body, a speaker, an earpiece, a sensor, and a control unit. The flexible body can be in a worn state in which a bending angle of the flexible body is not less than a predetermined angle, and in a flattened state in which the bending angle of the flexible body is less than the predetermined angle. When the sensor senses that the flexible body is in the worn state, the control unit controls the earpiece to be off and controls the speaker to be on or as a default sound generator, and when the sensor senses that the flexible body is in the flattened state, the control unit controls the earpiece to be on or as the default sound generator, and controls the speaker to be off.

First claim
