Ultrasound probes and ultrasound imaging devices

An ultrasound imaging device including a host, a coupler, and an ultrasound probe connected in sequence, one end of the ultrasound probe being connected to the host through the coupler, wherein the ultrasound probe includes:

• a piezoelectric layer (100);
• a backing layer (200) provided in a laminated arrangement with the piezoelectric layer (100);
• a first connector (300′), wherein
• the first connector (300′) is disposed between the piezoelectric layer (100) and the backing layer (200);
• the first connector (300′) is electrically connected to the piezoelectric layer (100);
• and
• the first connector (300′) is configured as a flexible circuit board;
• and
• a second connector (400′), wherein one end of the second connector (400′) is connected to the first connector (300′) and the other end is connected to a host.
