Proximity Sensor and Electronic Device

An electronic device, comprising:

• a housing;
• and
• a proximity sensor, arranged in the housing;
• wherein the proximity sensor comprises:
• a circuit board;
• an infrared emitter and an infrared receiver, both arranged on the circuit board, the infrared emitter comprising a light emitting source arranged on the circuit board and a light transmitting element covering the light emitting source, the infrared receiver being arranged on a side of the light emitting source;
• wherein the light emitting source has an emission optical axis, the light transmitting element comprises a front light transmitting portion and a rear light transmitting portion connected to the front light transmitting portion, the front light transmitting portion being located on a front side of the emission optical axis of the light emitting source, the rear light transmitting portion being located on a rear side of the emission optical axis of the light emitting source;
• and
• a light shielding element covering at least a part of the rear light transmitting portion.

An electronic device, comprising:

• a touch display comprising a display and a cover plate that covers the display;
• and
• a proximity sensor, wherein a light emitted and received by the proximity sensor is located outside the cover plate;
• the proximity sensor comprises:
• a circuit board;
• an infrared emitter and an infrared receiver, both arranged on the circuit board, the infrared emitter comprising a light emitting source arranged on the circuit board and a light transmitting element covering the light emitting source, the infrared receiver being arranged on a side of the light emitting source;
• wherein the light emitting source has an emission optical axis, the light transmitting element comprises a front light transmitting portion disposed close to the touch display, and a rear light transmitting portion disposed away from the touch display and connected to the front light transmitting portion, the front light transmitting portion being located on a front side of the emission optical axis of the light emitting source, the rear light transmitting portion being located on a rear side of the emission optical axis of the light emitting source;
• and
• a light shielding element covering at least a part of the rear light transmitting portion.
