Transducer for ultrasonic diagnosis device and method for manufacturing the same
View Patent ↗Disclosed is a transducer of an ultrasonic diagnosis device. Electrode patterns are formed inside a backing block, as one body, and thus, a prior art FPCB may be omitted.
1. A transducer of an ultrasonic diagnosis device, comprising:
a backing block;
a plurality of piezoelectric elements configured to transmit/receive an ultrasonic signal to/from a target object and arranged in a line on a front face of the backing block; and
first and second pluralities of electrode patterns made of conductive material, connected to the piezoelectric elements arranged in the line, and formed inside the backing block to be inclined with respect to the front surface of the backing block,
wherein one end of each electrode pattern of the first and second pluralities of electrode patterns is arranged on the front face of the backing block and the other end of the electrode patterns is arranged on a face of the backing block other than the front face,
wherein the first plurality of electrode patterns is formed inside the backing block such that each electrode pattern of the first plurality is formed on a first plane inclined in one direction with respect to a second plane that is normal to the front surface of the backing block, and wherein the second plurality of electrode patterns is formed inside the backing block such that each electrode pattern of the second plurality is formed on a third plane inclined in the other direction with respect to the second plane that is normal to the front surface of the backing block.
2. The transducer of claim 1 , wherein the electrode patterns are formed to be extended and to be in at least one of a shape of a band and a shape of a rod.
3. The transducer of claim 1 , further comprising:
a controller to control operations of the piezoelectric elements,
wherein one end of each electrode pattern of the first and second pluralities of electrode patterns forms first connecting parts that are arranged on the front face of the backing block and connected to the piezoelectric elements, and the other end of each electrode pattern of the first and second pluralities of electrode patterns forms second connecting parts that are arranged on the face of the backing block other than the front face and are connected to the controller.
4. The transducer of claim 3 , wherein the first connecting parts are arranged to form at least one line on the front face of the backing block.
5. The transducer of claim 1 , wherein each electrode pattern of the first and second pluralities of electrode patterns is formed inside the backing block to be inclined with respect to the front surface of the backing block so as not to be normal to the front surface of the backing block.
6. The transducer of claim 1 , wherein the ends of each electrode pattern of the first plurality of electrode patterns that are arranged on the front face of the backing block are arranged to form at least one line on the front face of the backing block.
7. The transducer of claim 1 , wherein the ends of each electrode pattern of the first plurality of electrode patterns that are arranged on the front face of the backing block are arranged to form a first line on the front face of the backing block, and the ends of each electrode pattern of the second plurality of electrode patterns that are arranged on the front face of the backing block are arranged to form a second line on the front face of the backing block that is parallel to and spaced apart from the first line.
8. The transducer of claim 4 , wherein the first connecting parts are arranged to form at least two lines on the front face of the backing block.
9. The transducer of claim 1 , wherein the backing block is a hexahedron.
