Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a true wireless Bluetooth headset and its antenna switching method, medium and device. Background Art

[0002] With the development of communication technology, headphones have gradually gotten rid of the constraints of wires. General Bluetooth headphones save the wire between the headphones and electronic devices. That is, the headphones and electronic devices are connected through Bluetooth technology, and the left and right ears of the headphones still need to be connected by wires.

[0003] For True Wireless Stereo (TWS), it is possible to completely get rid of the limitations of headphone cables. There are two main principles. One is the independent connection of the left and right ears, and the other is that when the main and sub-headphones are connected separately, the transmitting device needs to be connected to the main headphone first, and then the sub-headphones are connected after the connection is confirmed. In other words, compared with traditional "wireless headphones", the connection of true wireless headphones is not only the signal transmission between the headphones and the signal transmitting device, but also the wireless connection between the main and sub-headphones. Compared with traditional "wireless headphones", the structure of true wireless headphones is more complicated. Since true wireless headphones are not bound by headphone cables, the phenomenon of a single earphone being lost often occurs. The existing true wireless headphones have not been further optimized for multiple scenarios of headphones, resulting in a single function of true wireless headphones.

[0004] Based on this, there is an urgent need for a true wireless Bluetooth headset and its antenna switching method, medium and equipment to expand the usage scenarios of true wireless headsets and optimize the antenna function of true wireless headsets. Summary of the Invention

[0005] The embodiments of the present application provide a true wireless Bluetooth headset and its antenna switching method, medium and device, which are used to expand the usage scenarios of true wireless headsets and optimize the antenna function of true wireless headsets.

[0053] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0054] Figure 1 An example of an application scenario provided by an embodiment of the present application is shown in FIG. Figure 1 As shown, the electronic device and the headset are connected via Bluetooth technology. Bluetooth chips are respectively provided in the electronic device and the headset. Bluetooth technology is a short-range wireless communication technology that can effectively simplify the communication between mobile communication terminal devices such as computers, tablets, mobile phones, and smart watches. Figure 1 Computers, tablets, mobile phones, smart watches and other mobile communication terminal devices are collectively referred to as electronic devices, and the connection between them and headphones is demonstrated.

[0055] Bluetooth chip technology dictates that for each pair of devices to communicate, one must be the master and the other the slave. The master must perform the search, initiate pairing, and successfully establish a link before both devices can send and receive data. A Bluetooth-enabled electronic device can switch between these two roles. Normally, it operates in slave mode, waiting for a master device to connect. When necessary, it can switch to master mode and initiate calls to other electronic devices. To initiate a call in master mode, a Bluetooth device must know the other device's Bluetooth address, pairing password, and other information. Once pairing is complete, the call can be initiated directly. Every Bluetooth-enabled electronic device has its Bluetooth address and pairing password pre-set before leaving the factory.

[0056] by Figure 1 Take the scenario in as an example, the electronic device is used as the master device and the headset is used as the slave device. When connecting to the headset, first set the headset to be searchable. At this time, start the Bluetooth search function of the electronic device and search for the headset to be connected. Send a pairing request to it. Generally speaking, the headset can automatically accept pairing requests from other electronic devices. After pairing is completed, the corresponding information of the headset is saved in the common device list of the electronic device, and the electronic device can be connected by clicking again. After the connection is successful, audio signals can be transmitted between the headset and the headset.

[0057] In the above-mentioned connection method between headphones and electronic devices, the usage scenario of the headphones is only to transmit audio signals between the electronic devices, and there is no subdivision of the usage scenario. For example, in the scenario where the headphones are not connected to the electronic device, the headphones are very likely to be lost. At this time, the antenna of the headphones is idle and not fully utilized, and the lost headphones cannot be found. Alternatively, when the headphones are worn or not worn, human contact will affect the performance of the antenna. In the existing technology, this scenario is not subdivided. As a result, the function of the headphones is single.

[0058] Based on this, the present application provides a true wireless headset, which is used to expand the usage scenarios of the headset and optimize the antenna function of the headset.

[0059] Figure 2 A schematic diagram of a true wireless Bluetooth headset provided in an embodiment of the present application is shown as an example. Figure 2 As shown, the true wireless Bluetooth headset includes an antenna, a processor, a first switch, a Bluetooth module and a positioning module;

[0060] Figure 3 A schematic diagram of a first switch provided in an embodiment of the present application is exemplarily shown, as shown in FIG. Figure 3As shown, the first switch is provided with multiple pins, pin 1 and pin 3 can be connected to the Bluetooth module and the positioning module respectively, pin 2 is grounded, pin 4 is connected to the power supply, pin 5 is connected to the antenna, and pin 6 is connected to the external control signal. Figure 2 For clarity of illustration, only pins 1, 2, and 5 are shown.

[0061] The antenna connected to pin 5 is used to transmit and receive signals. Common antennas in Bluetooth technology include: onboard antennas, ceramic antennas, and external rod antennas. Onboard antennas are widely used in electronic devices with Bluetooth communication capabilities due to their low cost and good adjustability.

[0062] An antenna is a device used to send or receive electromagnetic waves in electronic devices with Bluetooth communication capabilities. When transmitting, it converts the high-frequency current of the transmitter into electromagnetic waves in space; when receiving, it converts the electromagnetic waves intercepted from space into high-frequency current and sends them to the receiver. Specifically, in the embodiments of the present application, the antenna can convert the high-frequency current of the transmitter in the true wireless Bluetooth headset into electromagnetic waves in space, so that the antenna of the electronic device connected to the true wireless Bluetooth headset can receive it. At the same time, it can also intercept the electromagnetic waves emitted by the antenna of the electronic device and convert them into high-frequency current and send them to the true wireless Bluetooth headset.

[0063] The processor is configured to send a first control signal to the first switch when the true wireless Bluetooth headset establishes a Bluetooth connection with the electronic device; and send a second control signal to the first switch when the true wireless Bluetooth headset does not establish a Bluetooth connection with the electronic device.

[0064] The processor can be integrated into the main control chip of the true wireless Bluetooth headset and can obtain the Bluetooth connection status between the electronic device and the true wireless Bluetooth headset. When the true wireless Bluetooth headset establishes a Bluetooth connection with the electronic device, the processor can send a high-level signal to the first switch as a first control signal; or when the true wireless Bluetooth headset and the electronic device do not establish a Bluetooth connection, the processor can send a low-level signal to the first switch as a second control signal. After receiving the high-level signal or the low-level signal, the first switch can conduct different paths.

[0065] Specifically, the first switch is used to open a first path between the antenna and the Bluetooth module based on a first control signal; and to open a second path between the antenna and the positioning module based on a second control signal. Figure 3 The first path is the path between pin 5 and pin 1, and the second path is the path between pin 5 and pin 3.

[0066] The Bluetooth module is used to perform data transmission processing and / or audio processing on the Bluetooth signal transmitted through the antenna.

[0067] In one possible implementation, an audio chip can be connected to the Bluetooth module. After the Bluetooth module receives the audio data transmitted by the electronic device through the antenna, it can transmit the audio data to the audio chip. The audio chip amplifies, filters, and processes the audio data, and finally transmits it to the player of the true wireless Bluetooth headset. Finally, the audio played by the electronic device can be heard through the true wireless Bluetooth headset. Alternatively, when using a true wireless Bluetooth headset for a call, the microphone of the true wireless Bluetooth headset can convert the analog signal of the sound into a digital signal, which is processed by the audio chip and transmitted to the Bluetooth module. The Bluetooth module transmits it to the electronic device through the antenna.

[0068] In another possible implementation, the functions of the Bluetooth module and the audio chip can be integrated into one chip, which can effectively reduce the space occupied by the true wireless Bluetooth headset.

[0069] The positioning module is used to determine positioning information through satellite signals transmitted by the antenna.

[0070] The positioning module does not rely on short-range communication between the electronic device and the true wireless Bluetooth headset, that is, it does not rely on Bluetooth communication technology. Instead, it communicates between positioning satellites and electronic devices. The electronic device can transmit a positioning signal to the satellite through the antenna. The satellite converts the positioning signal into a satellite signal and transmits it to the antenna of the true wireless Bluetooth headset. The positioning module analyzes the satellite signal and transmits its own positioning information to the satellite through the antenna. After receiving the positioning information, the satellite sends it to the electronic device, and the location of the true wireless Bluetooth headset can be displayed on the screen of the electronic device. This makes it easy to find the true wireless Bluetooth headset.

[0071] Through the above method, a positioning module is added to the true wireless Bluetooth headset, so that the positioning function can be realized when the Bluetooth is not connected, so as to match the antenna working mode of the true wireless Bluetooth headset when it is in a lost state, greatly expanding the function of the antenna and making the working mode of the true wireless Bluetooth headset more optimized.

[0072] Figure 4 A schematic diagram of another true wireless Bluetooth headset provided in an embodiment of the present application is shown as an example. Figure 4 As shown, the true wireless Bluetooth headset further includes: a second switch, a first impedance unit and a second impedance unit respectively connected to the second switch;

[0073] Figure 5 A schematic diagram of a second switch provided in an embodiment of the present application is exemplarily shown, as shown in FIG. Figure 5 As shown, the second switch is provided with multiple pins, pin 1 and pin 3 can be connected to the first impedance unit and the second impedance unit respectively, pin 2 is grounded, pin 4 is connected to the power supply, pin 5 is connected to the antenna, and pin 6 is connected to an external control signal. Figure 4For clarity of illustration, only pins 1, 2, and 5 are shown.

[0074] Since the size of true wireless Bluetooth headsets is small, the space occupied by the antenna in the headset is also relatively small. When the headset is worn on the human ear, the performance of the antenna will be affected by the human body. Specifically, the capacitance or inductance of the path connecting the true wireless Bluetooth headset to the antenna will be affected by the human body temperature, which in turn affects the power or sensitivity of the antenna to receive / transmit signals. Therefore, multiple paths are needed to adjust the performance of the antenna. Figure 4 In the embodiment, the third channel and the fourth channel are used to adjust the working performance of the antenna.

[0075] The processor is further configured to send a third control signal to the second switch when determining that the true wireless Bluetooth headset is in a worn state; and send a fourth control signal to the second switch when determining that the true wireless Bluetooth headset is not in a worn state.

[0076] Exemplarily, the third control signal may be a high-level signal, and the fourth control signal may be a low-level control signal.

[0077] Specifically, the second switch may connect a third path between the antenna and the first impedance unit based on a third control signal; and connect a fourth path between the antenna and the second impedance unit based on a fourth control signal.

[0078] Comparing the control logic of the first and second switches, the same switch model can be used, such as the MXD8625C, which is specifically designed for connecting to antennas. When pin 6 of the switch receives a high-level signal, RF2 and ANT are connected, connecting the path connected to pin 1 to the antenna. When pin 6 of the switch receives a low-level signal, RF1 and ANT are connected, connecting the path connected to pin 3 to the antenna.

[0079] Figure 6 A schematic diagram of a first impedance unit provided in an embodiment of the present application is shown as an example. Figure 6 As shown, the first impedance unit is a combination of two inductors in parallel and one capacitor in series, corresponding to the wearing state of the true wireless Bluetooth headset, the size of the capacitor and inductor can be adjusted under the influence of the human body. For example, the inductive reactance of the human body can be set to 1500 ohms, and the impedance can be adjusted by adding the human body. Figure 6 In the circuit of the first impedance unit, the sizes of the capacitors and inductors in the first impedance unit are adjusted so that when the influence of the human body is added, the final inductive reactance reaches the set value, which is the value with the best antenna performance.

[0080] Figure 7 A schematic diagram of a second impedance unit provided in an embodiment of the present application is shown as an example. Figure 7As shown, the second impedance unit is a combination of a capacitor and two inductors in series. The capacitance and inductance are adjusted to correspond to the unworn state of the true wireless Bluetooth headset, without the influence of the human body. The specific adjustment method can be referred to the adjustment of the first inductive reactance unit and will not be repeated here.

[0081] Through the above method, the working state of the true wireless Bluetooth headset is divided into a wearing state or a not-wearing state, and the influence of the human body on the true wireless Bluetooth headset antenna can be taken into account. By designing different inductive reactance units, the true wireless Bluetooth headset can conduct different paths under different working states, thereby realizing the adjustment of the antenna performance, so that the antenna can always work in the best performance state.

[0082] Optionally, the working state corresponding to the true wireless Bluetooth headset also includes a charging state, that is, the true wireless Bluetooth headset is located in the true wireless Bluetooth headset compartment. At this time, the true wireless Bluetooth headset is not connected to the electronic device through Bluetooth. To determine whether the above-mentioned true wireless Bluetooth headset is in a wearing state, it is necessary to establish a Bluetooth connection between the true wireless Bluetooth headset and the electronic device. At this time, the third channel and the fourth channel are used to adjust the working performance of the antenna under the Bluetooth connection.

[0083] Through the above method, the usage scenarios of true wireless Bluetooth headsets are further subdivided, so that the working performance of true wireless Bluetooth headsets and the usage scenarios are more closely matched, and the antenna performance of true wireless Bluetooth headsets is more optimized.

[0084] Optionally, to detect whether the true wireless Bluetooth headset is in a wearing state, a touch sensor can be used. The touch sensor is connected to the processor, and the signal collected to detect whether the headset is being worn can be transmitted to the processor. The processor analyzes the signal to form high and low level signals, which are transmitted to pin 6 of the second switch, thereby causing the second switch to turn on RF2 or RF1.

[0085] Figure 8 A circuit diagram of a true wireless Bluetooth headset provided in an embodiment of the present application is shown as an example. Figure 8 As shown, the Bluetooth module and the positioning module can be integrated into an integrated chip, and the antenna includes a first contact and a second contact; the first contact is connected to the first switch, and the second contact is connected to the second switch.

[0088] Step 902: The processor sends a first control signal to the first switch;

[0091] Step 905: The first switch, based on the second control signal, opens a second path between the antenna and the positioning module; the positioning module is configured to determine positioning information through the satellite signal transmitted by the antenna.

[0092] Optionally, after the true wireless Bluetooth headset establishes a Bluetooth connection with the electronic device, the processor determines whether the true wireless Bluetooth headset is in a wearing state;
