The mechanism has two hermetically sealed chambers i.e. loudspeakers (5, 6), of variable volumes, where an internal pressure of the chambers is able to increase or decrease alternately according to variations in surrounding temperatures. A mechanical connection i.e. rigid rod (7), is provided between the chambers that are arranged such that volume of one of hermetically sealed chambers decreases when volume of other chamber increases, and vice versa. The connection is connected to a mobile unit (10) that is capable of moving relative to the variations in the volume of the chambers. An independent claim is also included for a clock element. |
