[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0029] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the existing related technologies, Bluetooth headsets usually use independent touch detection chips to realize the touch function. In addition, lenses are added to the headsets to cooperate with infrared detection chips to realize in-ear detection. Therefore, there are hardware such as touch detection chips, infrared detection chips, lenses and Bluetooth chips in Bluetooth headsets. However, in order to facilitate users to wear Bluetooth headsets, there are great limitations in space. The above hardware has occupied most of the space in a limited space. There is not enough space to add new chips or hardware to add new functions, and there is no way to realize sliding touch playback volume on Bluetooth headsets. Therefore, how to maintain the two functions of in-ear detection and click touch, and integrate the volume adjustment function under the premise that Bluetooth headsets need to save space, has become a problem that needs to be solved urgently in the industry.

[0032] Based on this, a multifunctional Bluetooth headset is provided in the embodiment of the present application. Figure 1 , Figure 1 This is an optional module structure diagram of the multifunctional Bluetooth headset provided in an embodiment of the present application. The multifunctional Bluetooth headset provided in an embodiment of the present application includes a sensor module, a control module and a Bluetooth module.

[0033] In some embodiments, the sensor module includes an in-ear sensor module and a tactile sensor module, the in-ear sensor module is used to detect a first sensor signal, and the tactile sensor module is used to detect a second sensor signal. The in-ear sensor module is a sensor component for realizing an in-ear detection function, and the tactile sensor module is a sensor component for realizing a tactile operation detection function. The first sensor signal is a signal generated when the in-ear sensor module detects a change in an external factor, and the second sensor signal is a signal generated when the tactile sensor module detects a change in an external factor. It can be understood that the first sensor signal and the second sensor signal can be voltage signals.

[0034] It is understandable that the Bluetooth module is connected to the control module, thereby realizing wireless connection between the multifunctional Bluetooth headset and the external device. Among them, the external device is a Bluetooth device that can play audio, such as a mobile phone, a computer, a car multimedia device, etc. The Bluetooth module and the control module can communicate using the IIC protocol, or the UART serial communication protocol and the SPI protocol, etc. The communication protocol used by the Bluetooth module can be selected according to the actual situation. In addition, the embodiment of the present application does not limit the specific model of the Bluetooth module.

[0035] In some embodiments, the control module includes an in-ear analysis unit, a touch analysis unit, and a sliding analysis unit. Among them, the in-ear analysis unit is used to perform wearing posture analysis according to the first sensor signal to obtain the wearing state of the multifunctional Bluetooth headset corresponding to the target object. Among them, the wearing posture analysis is the process in which the in-ear analysis unit determines whether the multifunctional Bluetooth headset is worn normally according to the first sensor signal. The target object can be a user using the multifunctional Bluetooth headset. The wearing state includes normal wearing and abnormal wearing. When the multifunctional Bluetooth headset fits the user's ear, the user can use the multifunctional Bluetooth headset normally. At this time, the wearing state is normal wearing. When the multifunctional Bluetooth headset is separated from the user's ear, the wearing state is abnormal wearing.

[0036] In some embodiments, the in-ear sensor module includes at least two in-ear detection parts, and the in-ear detection parts can be metal sheets, wherein the metal sheets can be copper sheets with a smaller area and a thinner thickness. The in-ear detection parts are arranged in the near-ear surface area. It should be noted that when the wearing state of the multifunctional Bluetooth headset is normal wearing, the contact area between the surface of the multifunctional Bluetooth headset and the ear of the target object is the near-ear surface area.

[0037] It is understandable that at least two in-ear detection units are provided in the in-ear sensor module to avoid misjudgment of the wearing state due to accidental touch, because when the in-ear detection unit detects that it is in contact with the human skin, it will cause the corresponding capacitance value to change, thereby generating a first sensing signal, which is detected by the in-ear analysis unit, and then confirms that the in-ear detection unit is in contact with the user's skin. If there is only one in-ear detection unit, when the user takes off the earphone with his hand, the finger may also touch the in-ear detection unit, so that the in-ear analysis unit determines that the wearing state of the multi-functional Bluetooth headset is normal wearing, but the user is not wearing the multi-functional Bluetooth headset at this time. However, if there are more than two in-ear detection units, the in-ear analysis unit is set to receive the first sensor signals generated by all the in-ear detection units before judging the wearing state as normal wearing. In the above scenario where the user grabs the earphone with his hand, only one or part of the in-ear detection unit touches the finger, and the in-ear analysis unit will judge the wearing state as abnormal wearing, which reduces the misjudgment of the wearing state to a certain extent.

[0038] It should be noted that the in-ear analysis unit is also used to send a first control instruction according to the wearing status. Specifically, the first control instruction can be: displaying "Bluetooth headset is worn normally" on the display interface of the connected external device, displaying "Bluetooth headset is worn abnormally" on the display interface of the connected external device, and making the connected external device enter a preset state, etc. The specific functions that can be achieved by the first control instruction can be set according to the actual application scenario, and the embodiments of the present application are not limited to this. Exemplarily, when the wearing state is a normal wearing state, the in-ear analysis unit sends a first control instruction to control the connected external device to display "Bluetooth headset is worn normally" on its interactive interface. When the wearing state is an abnormal wearing state, the in-ear analysis unit sends a first control instruction to control the connected external device to display "Bluetooth headset is worn abnormally" on its interactive interface. Alternatively, when the wearing state is an abnormal wearing state, the in-ear parsing unit sends a first control instruction to control the connected external device to enter the anti-interference mode, that is, the external device regards the subsequently received control instruction as an erroneous touch operation and does not respond to it, that is, it no longer performs the control corresponding to the subsequent control instruction until the wearing state is a normal wearing state, and the in-ear parsing unit sends the first control instruction again to control the external device to exit the anti-interference mode and resume normal operation. Alternatively, when the wearing state is an abnormal wearing state, the in-ear parsing unit sends a first control instruction to stop the control module or the Bluetooth module from sending subsequent control instructions, so that the external device no longer receives other control instructions, until the wearing state is a normal wearing state, and the in-ear parsing unit sends the first control instruction again, at which time the Bluetooth module or the control module resumes normal operation.

[0039] In some embodiments, the touch analysis unit is used to analyze the touch operation according to the second sensor signal to obtain the click operation of the target object on the multi-functional Bluetooth headset. The touch operation analysis refers to the process in which the touch analysis unit determines whether the user makes a click operation according to the second sensor signal. The click operation can be a single click, a double click, or multiple clicks. The touch analysis unit is also used to send a second control instruction according to the click operation. Specifically, the second control instruction can be to pause audio, switch audio, play audio, answer a call, etc.

[0040] In some embodiments, the sliding analysis unit is used to analyze the sliding operation according to the second sensor signal to obtain the sliding touch operation of the target object on the multi-functional Bluetooth headset. The sliding operation analysis refers to the process in which the sliding analysis unit determines whether the user makes a sliding touch according to the second sensor signal. The sliding touch operation can be sliding in one direction, or sliding clockwise or counterclockwise. The sliding analysis unit is also used to send a third control instruction according to the sliding touch operation. The third control instruction can be to increase the volume or to decrease the volume.

[0041] It can be understood that the in-ear analysis unit, the touch analysis unit and the sliding analysis unit can be integrated into one processing unit to reduce the volume occupied by the control module, or any two units can be integrated into one unit if the space of the Bluetooth headset permits. The above-mentioned integrated units can be implemented in the form of hardware or in the form of software functional units.

[0042] It can be understood that the Bluetooth module provided in the embodiment of the present application is also used to send the first control instruction, the second control instruction and the third control instruction to an external device connected to the multi-functional Bluetooth headset.

[0043] In some embodiments, the tactile sensing module includes a plurality of touch control parts, and the touch control parts are used to detect touch pressure parameters, touch area parameters, and touch friction parameters. Specifically, the touch pressure parameter is the pressure value generated when the user clicks or slides the touch control part and touches the touch control part. The touch area parameter is the area of ​​the touch control part when the user clicks or slides the touch control part. The touch friction parameter is the friction coefficient between the touch control part and the object that issues the sliding touch operation when the user slides the touch control part.

[0044] It should be noted that the second sensing signal can be triggered by parameters such as touch pressure parameters, touch area parameters and touch friction parameters, so that the touch analysis unit and the sliding analysis unit can perform analysis. Exemplarily, when the detected touch pressure parameter exceeds the preset pressure threshold, it is judged that the user has triggered the corresponding touch control part. When the detected touch area parameter exceeds the preset area threshold, it is judged that the user has triggered the corresponding touch control part. The friction coefficient between human skin and the touch control part is used as the preset friction coefficient. When the touch friction parameter is the same as the preset friction coefficient, it is judged that the object that issued the sliding touch operation is a person, that is, the user triggered the corresponding touch control part. If the touch friction parameter is different from the preset friction coefficient, it means that the user has accidentally touched during use, and the object that issued the sliding touch operation is other objects, which may be rubber, or metal, etc.

[0045] In some embodiments, the touch portion includes a click touch portion and a slide touch portion, wherein the number of the click touch portion is at least one, and the number of the slide touch portions is at least three, and the three slide touch portions are set to avoid erroneous operations caused by accidental touches. In addition, the click touch portion and the slide touch portion are arranged in the far-ear surface area, and the far-ear surface area is the area where the surface of the multifunctional Bluetooth headset does not contact the ear of the target object when the multifunctional Bluetooth headset is normally worn, that is, the other surface area of ​​the multifunctional Bluetooth headset except the near-ear surface area.

[0046] The following examples introduce different ways of setting the click touch part and the sliding touch part. Embodiment 1 and Embodiment 2 will respectively illustrate the setting scenarios of the touch part and the sliding touch part in different true wireless stereo headphones (True Wireless Stereo), and Embodiment 3 will illustrate the scenario in which the touch part and the sliding touch part are set in a neck-hanging Bluetooth headset:

[0047] Embodiment 1

[0048] The multifunctional Bluetooth headset of this embodiment is provided with an ear handle, and the ear handle is a straight handle. The first sliding touch portion 1, the second sliding touch portion 2, the third sliding touch portion 3 and the click touch portion 4 are arranged on the surface area of ​​the far ear, please refer to Figure 2 , Figure 2 It is a structural schematic diagram of a multifunctional Bluetooth headset, wherein a first sliding touch portion 1, a second sliding touch portion 2 and a third sliding touch portion 3 are sequentially arranged on the ear handle.

[0049] When the sliding analysis unit detects that the user triggers the first sliding touch part 1, the second sliding touch part 2 and the third sliding touch part 3 in sequence, the volume of the external device is controlled to be lowered. When the sliding analysis unit detects that the user triggers the third sliding touch part 3, the second sliding touch part 2 and the first sliding touch part 1 in sequence, the volume of the external device is controlled to be increased. The user clicks the click touch part 4, and the in-ear analysis unit inside the Bluetooth headset sends a first control instruction to the external device connected to the multi-functional Bluetooth headset to perform a corresponding control operation.

[0050] Embodiment 2

[0051] The multifunctional Bluetooth headset of this embodiment is provided with an ear handle, and the ear handle is a crank, which can fit the contour of the user's ear so that the multifunctional Bluetooth headset is not easy to fall off when worn. The first sliding touch part 1, the second sliding touch part 2, the third sliding touch part 3 and the click touch part 4 are arranged on the far ear surface area, please refer to Figure 3 , Figure 3 It is a structural schematic diagram of another multifunctional Bluetooth headset, wherein the first sliding touch portion 1, the second sliding touch portion 2 and the third sliding touch portion 3 are sequentially arranged on the ear handle.

[0052] When the sliding analysis unit detects that the user triggers the first sliding touch part 1, the second sliding touch part 2 and the third sliding touch part 3 in sequence, the volume of the external device is controlled to be lowered. When the sliding analysis unit detects that the user triggers the third sliding touch part 3, the second sliding touch part 2 and the first sliding touch part 1 in sequence, the volume of the external device is controlled to be increased. The user clicks the click touch part 4, and the in-ear analysis unit inside the Bluetooth headset sends a first control instruction to the external device connected to the multi-functional Bluetooth headset to perform a corresponding control operation.

[0053] Embodiment 3

[0054] The multifunctional Bluetooth headset is connected to another multifunctional Bluetooth headset via the headset connection module 5, and the headset connection module 5 is provided with at least one operation block 6. Figure 4 , Figure 4 It is a structural diagram of another Bluetooth headset. In this embodiment, the headset connection module can be a connecting line, and the first sliding touch part 1, the second sliding touch part 2, the third sliding touch part 3 and the click touch part 4 are arranged on the operation block 6 in sequence.

[0055] When the sliding analysis unit detects that the user triggers the first sliding touch part 1, the second sliding touch part 2 and the third sliding touch part 3 in sequence, the volume of the external device is controlled to be lowered. When the sliding analysis unit detects that the user triggers the third sliding touch part 3, the second sliding touch part 2 and the first sliding touch part 1 in sequence, the volume of the external device is controlled to be increased. The user clicks the click touch part 4, and the in-ear analysis unit inside the Bluetooth headset sends a first control instruction to the external device connected to the multi-functional Bluetooth headset to perform a corresponding control operation.

[0056] It is understandable that the specific shape of the operating block can be a strip, a disc, a column, etc., and the embodiment of the present application is not limited to this.

[0057] When a user with long hair wears the Bluetooth headset as shown in Example 1 and Example 2, if he wants to perform a sliding touch operation, he needs to lift his hair behind his ears first to avoid the hair blocking the sliding touch part when sliding touch is performed. However, when lifting his hair, his hand may accidentally knock down the Bluetooth headset, or the hair may get entangled with the Bluetooth headset, causing the Bluetooth headset to fall off with the action, which is inconvenient to operate. The operation block has a certain size and is easy to find. Implementing tactile control operation on the operation block can avoid the above-mentioned Bluetooth headset being knocked off.

[0058] Next, the circuit diagram of a multifunctional Bluetooth headset provided by the embodiment of the present application will be introduced in combination with the fourth embodiment. Figure 5 As shown, Figure 5 It is a circuit diagram of a multifunctional Bluetooth headset provided in an embodiment of the present application.

[0059] Embodiment 4

[0060] In this embodiment, the IQS7222 chip is selected as the control module, and the power circuit supplies power to the control module or provides a reference voltage. The Bluetooth module is connected to the GPIO4 port, RDY / GPIO5 port, SCL / GPIO2 port, SDA / GPIO1 port and MCLR / GPIO6 port of the chip respectively. It can be understood that in this fourth embodiment, the Bluetooth module and the control module communicate using the IIC protocol.

[0061] In the fourth embodiment, the in-ear sensing module has two in-ear detection parts, namely the first in-ear detection part and the second in-ear detection part. The first in-ear detection part is connected to the CRX0 port through the resistor R119, and the second in-ear detection part is connected to the CRX1 port through the resistor R121. The tactile sensing module has three sliding touch parts and two click touch parts. The three sliding touch parts are respectively the first sliding touch part, the second sliding touch part and the third sliding touch part, and the two click touch parts are respectively the first click touch part and the second click touch part.

The in-ear detection part, click touch part and sliding touch part are all small and thin copper sheets, and all port detection functions of the chip are through capacitive sensing technology, that is, when the user touches the touch part, the capacitance value between the touch part and the corresponding sensor electrode inside the chip will change accordingly, and this change can be detected by the control module.

[0062] The circuit structure of this embodiment is simple in design and occupies a small volume. It can realize the functions of in-ear detection, click touch and slide touch to adjust the device volume in the limited space of the Bluetooth headset by using only one chip and multiple copper sheets.
