Abstract

This application relates to a wireless headset system and a wireless headset. The wireless headset system includes the wireless headset and a case. The case includes a lower cover, an upper cover, and an accommodation compartment. A first magnet is disposed on the upper cover. The wireless headset includes a processor and a magnetic sensor coupled to the processor. The magnetic sensor is configured to detect a magnetic field vector around the wireless headset, and transmit the detected magnetic field vector to the processor. The processor determines a status of the wireless headset based on the received magnetic field vector. The status of the wireless headset includes at least a state in which the case is closed and the headset is placed in the case, a state in which the case is open and the headset is placed in the case, and an out-of-case state.

Claims (30)

1 . A wireless headset system, comprising:

a wireless headset, comprising a processor and a magnetic sensor coupled to the processor, wherein the magnetic sensor is configured to detect a magnetic field vector around the wireless headset, and transmit the detected magnetic field vector to the processor, and wherein the magnetic sensor is a three-axis Hall effect sensor; and

a case comprising a first cover, a second cover, and an accommodation compartment, wherein the accommodation compartment is configured to accommodate the wireless headset, a first magnet is disposed on the first cover, a second magnet is disposed on the second cover, and the first magnet and the second magnet are on opposite sides of the wireless headset and the magnetic sensor is between the first magnet and the second magnet when the wireless headset is accommodated in the accommodation compartment; and

wherein the processor is configured to:

determine the case is closed and the headset is placed in the case when the received magnetic field vector satisfies a first vector threshold;

determine that the case is open and the headset is placed in the case when the received magnetic field vector satisfies a second vector threshold; and

determine that the wireless headset is in an out-of-case state when the received magnetic field vector satisfies a third vector threshold.

2 . The wireless headset system according to claim 1 , wherein a third magnet is disposed on the first cover, and the third magnet is configured to attach the wireless headset to the first cover.

3 . The wireless headset system according to claim 2 , wherein the third magnet and the first magnet are disposed at intervals.

4 . The wireless headset system according to claim 2 , wherein the third magnet and the first magnet are connected together.

5 . The wireless headset system according to claim 1 , wherein the processor is further configured to determine, based on the received magnetic field vector, that the wireless headset is in the state in which the case is open and the headset is placed on the first cover of the case.

6 . The wireless headset system according to claim 1 , wherein at least a portion of the wireless headset is symmetric around a central axis, and the magnetic sensor is disposed along the central axis.

7 . The wireless headset system according to claim 1 , wherein the wireless headset is configured to rotate freely in the accommodation compartment.

8 . The wireless headset system according to claim 1 , wherein the wireless headset further comprises a magnet that is configured to attach to the case, so that the wireless headset is accommodated in the case.

9 . The wireless headset system according to claim 1 , wherein an attach magnet is further disposed on the case, and is configured to implement closure and attachment of both the second cover and the first cover of the case, and the attachment magnet is outside of the accommodation compartment.

10 . The wireless headset system according to claim 1 , wherein the case is a headset case.

11 . The wireless headset system according to claim 1 , wherein the case is a carrier, the carrier is one of a watch, glasses, a necklace, a bracelet, a wristband, a ring, a power bank, an adapter, a handbag, luggage, a head-mounted apparatus, a tie, a mobile phone, a drinking cup, a mouse, a pen, a notebook, a racket, a ball, or a bicycle, and both the carrier and the wireless headset form a fusion product.

12 . The wireless headset system according to claim 1 , wherein determining that the case is open and the headset is placed in the case when the received magnetic field vector satisfies the second vector threshold comprises:

determining that the case is open and the headset is placed on the first cover.

13 . The wireless headset system according to claim 1 , wherein determining that the case is open and the headset is placed in the case when the received magnetic field vector satisfies the second vector threshold comprises:

determining that the case is open and the headset is placed on the second cover.

14 . A wireless headset, wherein the wireless headset is configured to be accommodated in an accommodation compartment of a case, the wireless headset comprises a processor and a magnetic sensor coupled to the processor, the magnetic sensor is configured to detect a magnetic field vector around the wireless headset, and transmit the detected magnetic field vector to the processor, wherein the magnetic sensor is a three-axis Hall effect sensor, and the processor is configured to:

determine the case is closed and the headset is placed in the case when the received magnetic field vector satisfies a first vector threshold;

determine that the case is open and the headset is placed in the case when the received magnetic field vector satisfies a second vector threshold; and

determine that the wireless headset is in an out-of-case state when the received magnetic field vector satisfies a third vector threshold; and

wherein the case comprises a first cover, a second cover, and the accommodation compartment, wherein a first magnet is disposed on the first cover, a second magnet is disposed on the second cover, and the first magnet and the second magnet are on opposite sides of the wireless headset and the magnetic sensor is between the first magnet and the second magnet when the wireless headset is accommodated in the accommodation compartment.

15 . The wireless headset according to claim 14 , wherein at least a portion of the wireless headset is symmetric around a central axis, and the magnetic sensor is disposed along the central axis.

16 . The wireless headset according to claim 14 , wherein the wireless headset is configured to rotate freely in the accommodation compartment.

17 . The wireless headset according to claim 14 , wherein the wireless headset is in a cylindrical shape.

18 . The wireless headset according to claim 14 , wherein the wireless headset further comprises a magnet that is configured to attach to the case, so that the wireless headset is accommodated in the case.
