Abstract
A loudspeaker for audible sound is described having a sound emitting element mounted onto a support structure and at least one actuator adapted to rotate said sound emitting element around a hinge section, wherein the actuator is made of piezoelectric material. In variants the actuator forms part of the hinge section and the loudspeaker is capable of generating vibrations through its support structure.
Claims6
A loudspeaker for audible sound comprising a sound emitting element mounted onto a support structure and at least one actuator arranged to move said sound emitting element to generate sound, the actuator having a tubular shave with a removed sector and adapted to make a rotational movement between edges of the actuator formed by the removed sector when activated, the actuator being attached to the support structure and the sound emitting element by the respective edges and the motion of the sound emitting element including rotation.
A portable electronic device comprising a loudspeaker for audible sound comprising a sound emitting element mounted onto a support structure and at least one actuator arranged to move said sound emitting element to generate sound, the actuator having a tubular shape with a removed sector and adapted to make a rotational movement between edges of the actuator formed by the removed sector when activated, the actuator being attached to the support structure and the sound emitting element by the respective edges and the motion of the sound emitting element including rotation.
