  • Publication number: 20230055725
    Abstract: A speaker includes a housing having walls that define a cavity and a diaphragm covering the cavity and configured to vibrate under application of a magnetic field. The vibration produces sound waves. The walls are configured to deform under bending stress. The speaker is configured produce the sound waves both in an undeformed state and in a deformed state. Another speaker includes a flexible layer, a sensor configured to detect a curvature of the flexible layer, and a transducer disposed on and configured to vibrate the flexible layer. The vibrations of the flexible layer generate sound waves and output generated by the transducer is based on the curvature of the flexible layer.
