Document Type and Number:
WIPO Patent Application WO/2011/010494
Kind Code:
A1
Abstract:
An object detection device is provided with a ultrasound sensor (10) which comprises a wave transmitter (11) for converting an electric signal to a ultrasound wave, and detects an object using the ultrasound wave; and a baffle (20) which protects the wave transmitter (10). The wave transmitter (11) is provided, on its front side, with an acoustic hole (111) for transmitting the ultrasound wave. The baffle (20) comprises a plate-shaped mask (21) to cover the front side of the wave transmitter (11), and an opening (22) which is formed on the mask (21) for transmitting the ultrasound wave. The opening (22) has a quadrilateral shape wherein the length of the longitudinal side is different from the length of the lateral side. The size of the opening (22) is smaller than the size of the acoustic hole(111).
