Abstract:
The present invention relates to acoustic properties of a terminal device of a telecommunication network. To improve the capability of the terminal device to maintain the sound quality good while the distance between the speaker and the ear changes, the enclosure of the terminal device is provided with means (71, 81) for conveying the acoustic waves generated backwards by the speaker (30) of the device inside the enclosure to a cavity-like antenna space (80) intended for the antenna of the terminal device.
