line of the second branch its upper surface is connected to a vibration oscillator output in the radio telephone via a vibration conductor 361 and the lower surface via a second vibration conductor 362 as in fig2 b the radiating plane is rigidly attached to a circuit board beneath it at that end of the second piezoelectric element which is closer to the beginning of the second branch thus when a ringing signal arrives at the second piezoelectric element the second branch 312 from said attachment point to the free end vibrates according to the ringing voltage variation to enable vibration of the second branch the frame 340 between the radiating plane 310 and ground plane following the outer edge of the radiating plane is not rigid at least for the length of the second branch in fig3 this flexible portion of the frame is denoted by reference number 345 0021 fig4 a shows a fourth example of integration according to the invention in a radio telephone the structure illustrated by this example combines a radio telephone antenna at least one speaker and a vibrator the basic structure differs from the structure depicted in fig2 in that the antenna ground plane 420.
