Title:
COMPOSITE PHYSICAL FOCUSED TRANSDUCER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/119316
Kind Code:
A1
Abstract:
Provided are a composite physical focused transducer and a manufacturing method therefor, wherein same relate to the technical field of focused ultrasound. The transducer comprises a housing (1) and multiple composite transduction units (2). A front end of the housing (1) is provided with multiple through holes (102). Each of the composite transduction units (2) is inserted into a respective through hole (102), and axes of the multiple composite transduction units (2) are directed towards the same point. The composite transduction units (2) are connected to electrode leads. Each of the composite transduction units does not require press-molding, thereby avoiding the situation where a small transducer is prone to fracturing when being press-formed. With the equivalent energy, the transducer meets the requirements for a light mass, a small volume, a small focus and head-mounting, and can be applied to studies on mouse behaviors through ultrasonic stimulation. The transducer will not affect a mouse movement behavior during stimulation, thus ensuring the performance of a scientific study.
