Abstract
An arrangement designed for radio phones for integrating a mechanical structure of the antenna head of the phone. The mechanical structures of an antenna and a speaker of the radio phone are integrated so that a given planar component radiates both radio waves and sound waves. The radiator component (310) comprises a layer (315, 316) of a material, a shape of which can be controlled by means of a voltage. The sound waves, i.e. fluctuation of the air pressure are thus generated by causing the thickness or position of the layer to fluctuate according to the control voltage. The antenna head of the radio phone becomes more compact than in the prior art, and it takes up less space because the antenna and the speaker utilize same structural elements.

An arrangement for integrating a mechanical structure of an antenna head of a radio phone and a speaker, the mechanical structure including a ground plane, a planar antenna having at least one antenna feed conductor, and speaker first and second audio conductors, the arrangement comprising:
- a radiator component that is arranged to function both as a radio wave radiator for the planar antenna and as a sound wave radiator for the speaker;
- and
- said antenna feed conductor and one of said audio conductors being galvanically connected to a same conductor plane in the radiator component, wherein the conductor plane is short-circuited at a certain point to the ground plane to form a PIFA type antenna.
A radio phone comprising:
- a planar antenna with a feed conductor;
- a speaker with two audio conductors;
- a radiator component arranged to function both as a radio wave radiator in the planar antenna and as a sound wave radiator in the speaker;
- said feed conductor and one of said audio conductors being galvanically connected to a first conductor plane in the radiator component;
- and
- a second conductor plane in the radiator component being short-circuited at a certain point to a ground plane to form a PIFA type antenna.
