Detailed Description

To make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

The present disclosure provides a wireless headset, which can implement touch operation detection and automatic wearing detection, as shown in fig. 1, the wireless headset includes: and the first side of the touch chip 1 is connected with the wearing detection module 2, and the second side of the touch chip 1 is connected with the touch detection module 3. The first side of the touch chip 1 is connected to the wear detection module 2 through a connection area 6, and the second side of the touch chip 1 is connected to the touch detection module 3 through a connection area 5.

In the present disclosure, the wearable detection module 2 and the touch detection module 3 may both adopt capacitive sensors, and for convenience of description, the capacitive sensor that realizes the wearable detection module 2 is referred to as a first capacitive sensor, and the capacitive sensor that realizes the touch detection module 3 is referred to as a second capacitive sensor.

In addition, in the present disclosure, the third side of the touch chip 1 and the first connector 4 are connected through the connection region 7. The first connector 4 is used for being matched with a second connector of a main board of the wireless earphone to use, and interaction between the touch chip and the main board of the earphone is achieved.

Because the wearing detection module 2 and the touch detection module 3 both adopt capacitive sensors, the structure shown in fig. 1 in the present disclosure can be integrated on an FPC, and the

connection areas

5, 6, and 7 are wires disposed on the FPC, so that the communication and interaction of the touch chip 1 with the wearing detection module 2, the touch detection module 3, and the first connector 4 can be respectively realized.

Due to the characteristics of the FPC, the structure shown in fig. 1 provided by the disclosure can be suitable for wireless earphones in various shapes, and the proportion of the internal space of the earphones occupied by each part in the structure can be adjusted according to different earphone shapes so as to be suitable for the appearance characteristics of the earphones.

In an example of the present disclosure, a headset includes an earbud portion and a stem portion. For convenience of description, an area of the FPC corresponding to the wearing detection module 2 is referred to as a first FPC, and an area of the FPC corresponding to the touch detection module 3 is referred to as a second FPC. The first FPC may be disposed on an inner wall of the shell of the earbud and the second FPC may be disposed on an inner wall of the shell of the earstem. Fig. 2 and 3 show an example of the above structure applied to a wireless headset.

The earphone structure provided in the disclosure can realize wearing detection and touch detection of the wireless earphone.

The wearing detection module 2 is configured to detect a jump of the first capacitance signal and provide the jump to the touch chip 1. The touch detection module 3 is configured to detect a jump of the second capacitance signal and provide the jump to the touch chip 1.

The capacitive sensor can detect a jump of a capacitive signal (for example, a jump of a voltage) generated by an environmental change, and the jump of the capacitive signal is provided to the touch chip, so that the touch chip can analyze the capacitive signal to determine whether the wireless headset is worn or not, or whether a touch operation is performed on the wireless headset or not. For example: when the first capacitive sensor detects the voltage jump, the voltage jump amount can be provided to the touch chip 1; the touch chip 1 analyzes the voltage jump quantity, and when the voltage jump quantity is equal to or larger than a preset threshold value, the wearing state of the earphone can be determined to be changed. When the second capacitive sensor detects the voltage jump, the voltage jump amount can be provided to the touch chip 1; the touch chip 1 analyzes the voltage jump quantity, and when the voltage jump quantity satisfies a certain threshold interval, determines the operation corresponding to the threshold interval as the touch operation occurring on the earphone (the mapping relationship between the threshold area and the touch operation can be preset).

The wearing state and the touch operation of the wireless earphone detected by the touch chip 1 are sent to the mainboard of the earphone through the first connector 4, and interaction is carried out between the mainboard of the earphone and the host end matched with the earphone for use. For example, when it is determined that the headset is worn, the state is notified to the host, which may trigger the host to immediately execute a certain associated operation; when a certain touch operation acting on the earphone is detected, the host end can be triggered to execute a certain associated operation according to the operation.

In addition, based on the above structure of the present disclosure, the touch chip 1 can also control the on and off of the touch detection module 3 according to the wearing state of the earphone. For example, when the touch chip 1 determines that the earphone is worn, the touch detection module 3 can be immediately turned on, and then the touch detection module 3 can detect a touch operation in real time; when the touch chip 1 determines that the earphone is switched to the unworn state, the touch detection module 3 can be immediately turned off, and the touch operation function is turned off. Thus, power consumption of the headset can be saved.

In the structure of the present disclosure, both the capacitive sensor for wearing detection and the capacitive sensor for touch operation detection can be implemented in an FPC manner, the deployment of the FPC is small in space requirement, easy to integrate, and cost-saving, and in addition, the present disclosure optimizes the processing logic of the capacitance signals (i.e., the jump of the capacitance) detected by the two sensors, and can use the same touch chip, thereby saving cost and power consumption.
