Abstract: An ultrasonic oscillator element, including a substrate, a first lower electrode, a first insulating layer, a second insulating layer, a second lower electrode, a first upper electrode, and a third insulating layer. The first lower electrode is disposed on the substrate. The first insulating layer is disposed so that the first lower electrode is located between the first insulating layer and the substrate. The second insulating layer and the first insulating layer form a first cavity. The second lower electrode is disposed adjacent to the first side of the second insulating layer and located in the outer region of the first cavity. The first upper electrode is disposed on the second side of the second insulating layer. The third insulating layer is disposed so that the second lower electrode is located between the third insulating layer and the first insulating layer.

Abstract: An ultrasonic vibration sub-element including a substrate, a ground layer, a first insulation layer, a second insulation layer, a first electrode layer, a third insulation layer, and a second electrode layer is provided. The first electrode layer is configured to receive a direct current voltage. The second electrode layer is configured to receive an alternating current signal. Before the ultrasonic vibration sub-element is driven, there is a cavity between the first insulation layer and the second insulation layer. When the ultrasonic vibration sub-element is driven, the first electrode layer receives the direct current voltage and is configured to at least drive the second insulation layer to shrink toward the cavity. The second electrode layer receives the alternating current signal and is configured to at least drive the third insulation layer to vibrate. An ultrasound probe is also provided.

Abstract: A fixing module suitable for fixing to one of a first end and a second end of a screen bracket is provided. The fixing module includes a first part and a second part. The second part is slidably connected to the first part. The fixing module is configured to be fixed to the first end of the screen bracket by the first part or fixed to the second end of the screen bracket by the second part.

Abstract: A display device includes a screen, a screen stand and a fixing module. The screen stand is pivotally connected to the screen. The fixing module is connected to the screen stand and configured to clamp a first surface and a second surface of a board and includes a connecting element, a first abutting element and a second abutting element. The first abutting element is fixed to the connecting element and configured to abut against the first surface of the board. The second abutting element is pivotally connected to the connecting element and includes an abutting end configured to abut against the second surface of the board.

Abstract: A magnetic template with adjustable magnetic force is provided. The magnetic template is applied to a display device. The display device can be fixed on a plane by the magnetic template, wherein the magnetic template includes an assembly shell and an adjustment element. A magnetic element is arranged inside the assembly shell. The adjustment element is arranged in the assembly shell and is configured to adjust the magnetic force of the magnetic element relative to the plane or adjust the magnetic force of the magnetic element.

Abstract: A display device includes a screen, a screen support and a fixing module. The screen support is pivotally connected to the screen, and the screen support includes a first end and a second end. The fixing module is detachably connected to the screen support and includes a first sub-component and a second sub-component. The first sub-component has a first surface and a second surface, and the first sub-component is selectively connected to one of the first end and the second end. The second sub-component has a third surface and a fourth surface, and the second sub-component is configured for clamping a board. One of the first surface and the second surface of the first sub-component and one of the third surface and the fourth surface of the second sub-component are detachably connected.
