Abstract: A speaker (100) includes a housing (102) having walls (104, 106) that define a cavity (108) and a diaphragm (114) covering the cavity (108) and configured to vibrate under application of a magnetic field. The vibration produces sound waves. The walls (104, 106) are configured to deform under bending stress. The speaker (100) is configured produce the sound waves both in an undeformed state and in a deformed state. Another speaker (400) includes a flexible layer (432), a sensor (426) configured to detect a curvature of the flexible layer (432), and a transducer (434) disposed on and configured to vibrate the flexible layer (432). The vibrations of the flexible layer (432) generate sound waves and output generated by the transducer (434) is based on the curvature of the flexible layer (432).
