Patent number: 10151828Abstract: A sensor system is provided which includes an electroacoustic transducer, which is designed as a thickness oscillator and accordingly includes a front element having a bottom area and an end face, at least one disk-shaped piezoelectric element having a first surface and a second surface, and a rear element having a first end face and a second end face, the end face of the front element being coupled to a diaphragm which is suitable for emitting and receiving sound waves. The bottom area of the front element is joined to the first surface of the piezoelectric element integrally and/or in a force-fit manner, and the second end face of the rear element is joined to the second surface of the piezoelectric element integrally and/or in a force-fit manner. The distance between the first end face and the second end face of the rear element, plus half of the thickness of the piezoelectric element, corresponds to half of the wavelength of a resonance oscillation of the sensor system in the thickness direction.Type: GrantFiled: July 9, 2014Date of Patent: December 11, 2018Assignee: ROBERT BOSCH GMBHInventors: David Bartylla, Attila Kovacs

Patent number: 9968966Abstract: An electroacoustic transducer includes: a housing; an oscillating structure including at least one disk-shaped piezoelectric element having first and second surfaces; an acoustic transmitter; and electrical connecting element contacting electrodes of the piezoelectric element. The acoustic transmitter has parallel first and second surfaces, which first surface is joined to the first surface of the piezoelectric element, and which second surface is suitable for emitting and/or receiving sound waves. The distance between the second surface of the acoustic transmitter and the second surface of the piezoelectric element corresponds to ΒΌ of the resonance oscillation wavelength of the oscillating structure. The piezoelectric element is connected to the housing with the aid of a bearing structure which allows transverse strains of the piezoelectric element.Type: GrantFiled: May 26, 2014Date of Patent: May 15, 2018Assignee: Robert Bosch GmbHInventors: Andre Gerlach, David Bartylla

Patent number: 9763009Abstract: An electroacoustic transducer is provided that combines the properties and advantages of the known concepts of the thickness mode transducer and of the bending transducer with each other. For this purpose, an electroacoustic transducer is provided, which includes a housing and an oscillating structure. The oscillating structure is formed by at least one piezoelectric element, a diaphragm, and an acoustic transmitter. It is provided that the diaphragm is designed as a bending transducer, and the acoustic transmitter is designed as a thickness mode transducer.Type: GrantFiled: May 26, 2014Date of Patent: September 12, 2017Assignee: ROBERT BOSCH GMBHInventors: David Bartylla, Andre Gerlach

Patent number: 9383443Abstract: An ultrasonic sensor includes a housing having a peripheral side wall and a base surface, i.e., it is configured as essentially pot-shaped. The base surface is configured as a diaphragm. A transducer element, which is configured as a piezoelectric element, for example, and is used for generating and detecting ultrasonic oscillations, is situated on the base surface. At least one mass element is situated on the base surface so that the resistance of the mass element against an oscillation of the diaphragm increases with rising oscillation frequency.Type: GrantFiled: April 5, 2013Date of Patent: July 5, 2016Assignee: ROBERT BOSCH GMBHInventor: David Bartylla
