Abstract
A conduction receiver utilizing sound transmission through a solid medium includes an outer casing, a vibration reed, a magnet, a washer, a coil, and a lid. The lid covers surfaces of the outer casing to form a sealed first receiving space. The vibration reed, the magnet, the washer, and the coil are all arranged in the first receiving space. A peripheral surface of the vibration reed is coupled to the outer casing. The magnet is arranged at a side of the vibration reed away from a bottom of the outer casing. The washer is arranged at a side of the magnet away from the vibration reed. A first end of the coil is fixed to an inner surface of the lid, and a second end of the coil extends into the first receiving space and is coiled around the magnet and the washer. An electronic device is also provided.
