Abstract: An audio generating arrangement for an electronic device, the arrangement including at least one loudspeaker, a first body, and a second body at least partially enclosing the loudspeaker. At least one of the first body and the second body is moveable with respect to the other body. An acoustic cavity is formed by the loudspeaker and at least one of the first body and the second body. A volume of the acoustic cavity is configured to increase or decrease in response to movement of the first body or the second body. The arrangement in an electronic device enables increasing the volume of the acoustic cavity without also increasing the outer dimensions of the device.

Abstract: The disclosure concerns a communication device comprising a housing with a front body and a main body. The front body comprises a display unit having a plurality of layers attached to one another. The plurality of layers comprises a suspension layer and a second layer, wherein one of the layers is a display. At two opposing edges of the suspension layer, the suspension layer extends laterally beyond at least the second layer. The suspension layer is suspended by attachment of the two opposing edges to the main body. By extending the suspension layer laterally beyond at least the second layer of the plurality of layers and by attaching the suspension layer to the main body, the entire display unit is efficiently suspended and is movable up and down in a manner efficient for the emission of sound.

Abstract: An apparatus includes a first support member, a second support member and one or more electro-active polymer members between the first support member and the second support. The one or more electro-active polymer members include a first end configured to be coupled to the first support member, a second end configured to be coupled to the second support member and a middle portion located between the first end and the second end, where the middle portion includes a curved member in a first state of the one or more electro-active polymer members. A curved shape of the one or more electro-active polymer members is configured to create linear movement in a vertical direction, by bending in a curved direction.

Abstract: A magnet actuator (1) for use in an electronic device, comprising a first magnet arrangement (2), a second magnet arrangement (3), comprising a first magnet (3a) and a second magnet (3b), and a coil (4) arranged between the first magnet arrangement (2) and the second magnet arrangement (3). The first magnet arrangement (2) and the second magnet arrangement (3) are arranged so that magnetic fields, generated by the first magnet arrangement (2) and the second magnet arrangement (3), causes an attractive force (F1) and a repulsive force (F2) between the first magnet arrangement (2) and the second magnet arrangement (3), which maintain the first magnet arrangement (2) and the second magnet arrangement (3) in a force equilibrium state.
