An electrically conductive network which, at one end, has a low-resistance connection with a user's hand and, at the other end, has a high-resistance connection with ground. This protects electrical equipment such as a telephone keyset from electrostatic discharge and also protects the user from unpleasantly high discharge currents.

Electrostatic discharge protection device

An electro-acoustic transducer is arranged within the handset of a telephone instrument. The transducer is elastically seated and is seated at a distance from the walls of the handset so that noises caused by the handset are not transmitted onto the transducer.
