Abstract
A pest repeller including at least a first ultrasound transmitter mounted on a base and a second transmitter rotatably mounted above the first transmitter. Both transmitters can be rotatably mounted on a common post carried by the base. The arrangements permit a greater ultrasound coverage of an area because of the relative rotation of the superimposed speakers.
