Abstract
A sensing module includes a first coil, a control component coupled to the first coil, and a shielding component positioned at least on a first side of the first coil. The control component is configured to drive the first coil to transmit a first emitting electromagnetic signal, and to receive an induction signal generated from the first coil induced due to a first feedback electromagnetic signal. The shielding component shields at least a portion of the first emitting electromagnetic signal transmitting toward a first direction.
Claims18
A sensing module for a wearable device, including:
- a first coil having a first side toward to the wearable device, and a second side opposite to the first side;
- a control circuitry coupled to the first coil, wherein the control circuitry is configured to drive the first coil to transmit a first emitting electromagnetic signal to a wearing portion of the wearable device, and to receive a first induction signal generated from the first coil in response to a first feedback electromagnetic signal;
- and
- a shielding component forming an accommodating space for the first coil, the shielding component including:
- a shielding surface positioned at the first side,
- a shielding wall surrounding the first coil, and
- a contraction structure extending from the shielding wall toward an axis of the first coil to define a restricted opening at the second side of the first coil.
A wearable device, including:
- a wearing structure;
- a body combined with the wearable structure;
- and
- a sensing module, including:
- a first coil having a first side toward to the wearable device, and a second side opposite to the first side;
- a control circuitry coupled to the first coil, wherein the control circuitry is configured to drive the first coil to transmit a first emitting electromagnetic signal to a wearing portion of the wearable device, and to receive a first induction signal generated from the first coil in response to a first feedback electromagnetic signal;
- and
- a shielding component forming an accommodating space for the first coil, the shielding component including:
- a shielding surface positioned at the first side,
- a shielding wall surrounding the first coil, and
- a contraction structure extending from the shielding wall toward an axis of the first coil to define a restricted opening at the second side of the first coil;
- wherein the body is positioned on the first side of the sensing module, and the shielding component of the sensing module is positioned at least between the body and the first coil of the sensing module.
