Communication terminal with antenna
View Patent ↗A communication terminal is provided with an electromagnetic transmission or receiving antenna, an acoustic converter, preferably housed in a mobile telephone or cordless telephone.
1. A communication terminal, comprising:
an electromagnetic antenna for at least one of transmitting and receiving; and
at least one energizable device for acoustic sound conversion, wherein at least part of the electromagnetic antenna includes an antenna surface configured as a support for the energizable device, with the energizable device having a membrane formed from and including part of the antenna surface for acoustic sound conversion.
2. A communication terminal as claimed in claim 1 , wherein the acoustic sound conversion is performed at least one of electrodynamically and electromechanically.
3. A communication terminal as claimed in claim 1 , wherein the membrane is configured for acoustic sound generation.
4. A communication terminal as claimed in claim 1 , wherein the membrane is shaped via a membrane crease.
5. A communication terminal as claimed in claim 4 , wherein the membrane is connected continuously through the membrane crease to the surrounding antenna surface.
6. A communication terminal as claimed in claim 4 , wherein the membrane is connected only partially through the membrane crease to the surrounding antenna surface.
7. A communication terminal as claimed in claim 1 , wherein the membrane is configured as a metal and is capable of oscillation.
8. A communication terminal as claimed in claim 1 , wherein the membrane is configured as a thinner section of material in part of the antenna.
9. A communication terminal as claimed in claim 1 , wherein the membrane has a piezo-ceramic layer.
10. A communication terminal as claimed in claim 9 , wherein the antenna surface has an electrical counter-contact for the piezo-ceramic layer.
11. A communication terminal as claimed in claim 10 , wherein the electrical counter-contact for the piezo-ceramic layer is applied to a direct-current balancing potential.
12. A communication terminal as claimed in claim 1 , wherein the antenna is one of a patch antenna and a PIFA antenna.
