In one exemplary embodiment, a Bluetooth signal transmitting device is provided, which is applicable to Bluetooth devices. Referring to fig. 1, the bluetooth signal transmitting apparatus includes a main antenna 1 (e.g., a conductor such as a copper plate) and a parasitic antenna 2 (e.g., a conductor such as a copper plate), wherein the wiring direction of the main antenna 1 is different from the wiring direction of the parasitic antenna 2, and when currents are present in both the parasitic antenna 2 and the main antenna 1, the current directions of the two are different. Therefore, the Bluetooth signal strength of the Bluetooth signal transmitting equipment in different directions can be adjusted by controlling the state of the parasitic antenna 2 so as to better meet the requirements of users.

In which the parasitic antenna 2 is in the second state, the bluetooth signal of the bluetooth signal transmitting device is only transmitted by the main antenna 1, and at this time, the radiation range of the bluetooth signal may be denoted as a first radiation range. The parasitic antenna 2 is in the first state, the parasitic antenna 2 and the main antenna 1 can both transmit bluetooth signals, the bluetooth signals transmitted by the two can affect each other, and at this time, the radiation range of the bluetooth signal transmitting device can be recorded as a second radiation range. Since the bluetooth signal emitted by the parasitic antenna 2 and the bluetooth signal emitted by the main antenna 1 may interact, the first radiation range and the second radiation range may be different.

The wiring direction of the main antenna 1 and the wiring direction of the parasitic antenna 2 can be set inversely, so that the difference between the parasitic antenna 2 and the radiation direction of the main antenna 1 can be realized, the radiation direction of the bluetooth signal transmitting device can be adjusted in a large range by the state of the parasitic antenna 2 more easily, the adjustment of the bluetooth signal intensity in different directions can be realized better, the user requirements can be met better, and the use experience of the user can be improved.

Wherein the states of the parasitic antenna 2 comprise a first state and a second state. That is, in the bluetooth signal transmitting device, the parasitic antenna 2 can be controlled to be in the first state or the second state by the switch unit 3, so as to adjust the bluetooth signal strength in different directions, so as to better meet the requirements of users.

For example, the bluetooth signal transmitting device is a bluetooth headset, and when the bluetooth headset is in a bluetooth connection state with the mobile phone, it is determined that when the parasitic antenna 2 is in the first state (or the second state), the bluetooth communication effect between the bluetooth headset and the mobile phone is better, however, the bluetooth connection between the bluetooth headset and the mobile phone is still intermittent.

When the grounding switch is in the contact B, which is in the closed state, the parasitic antenna 2 is grounded and the parasitic antenna 2 is in the first state. Under this condition, the main antenna 1 and the parasitic antenna 2 both radiate bluetooth signals, and the bluetooth signals radiated by the parasitic antenna 2 and the bluetooth signals radiated by the main antenna 1 mutually affect each other, so that the overall radiation direction of the bluetooth signal transmitting device is shown as a dashed oval X2 in fig. 1, that is, bluetooth devices realize bluetooth communication connection with other devices through the bluetooth signals jointly radiated by the main antenna 1 and the parasitic antenna 2, and when other devices are located at the W2 position in fig. 1, the signal strength of the two bluetooth communication is better, so that better bluetooth communication can be ensured.

Therefore, the Bluetooth signal transmitting equipment can control the state of the parasitic antenna 2 through the opening or closing of the grounding switch, and further can control the radiation direction of Bluetooth signals of the Bluetooth signal transmitting equipment, so that the adjustment of the Bluetooth signal intensity in different directions is realized, the user requirements are better met, and the use experience of a user is improved.

The parasitic antenna 2 is in the first state, the feed unit 4 can apply the second current to the main antenna 1 through the contact D, at this time, the main antenna 1 radiates the bluetooth signal under the action of the second current, meanwhile, since the parasitic antenna 2 is grounded and is not a suspended metal conductor, the parasitic antenna 2 radiates the bluetooth signal, and the bluetooth signal emitted by the blue signal emitting device has better intensity in the direction indicated by the dashed oval X2 in fig. 1.

In bluetooth signal transmission equipment's main antenna 1 and parasitic antenna 2, main antenna 1 is located the position that is close to bluetooth headset's speaker 20, and parasitic antenna 2 is located the position of keeping away from speaker 20 to main antenna 1 and parasitic antenna 2 in bluetooth headset reverse the setting, thereby be convenient for realize the adjustment of the bluetooth signal strength of different orientation in the bluetooth headset, in order to satisfy user's demand better, promote user's use experience.

Example 1 in the case of the use of the heat-sensitive material,

referring to fig. 1 to 3, the bluetooth device is a bluetooth headset including a bluetooth chip 5, a main antenna 1, a parasitic antenna 2, a switching unit 3, and a feeding unit 4. The switching unit 3 comprises a ground switch for controlling whether the parasitic antenna 2 is grounded. The feeding unit 4 comprises a switch for controlling the magnitude of the feeding current. The bluetooth chip 5 is connected to the main antenna 1 and is grounded through a changeover switch.

The change-over switch controls the impedance matching of the main antenna 1 and the Bluetooth chip 5 through different states, so that the magnitude of feed current is controlled.

When the grounding switch is in the contact A, when the grounding switch is in the disconnection state, the parasitic antenna 2 is not grounded, the parasitic antenna 2 is in the first state and the second state, in this case, the switch is located in the contact C, the Bluetooth chip 5 applies a first current to the main antenna 1, only the main antenna 1 radiates Bluetooth signals, the radiation direction of the Bluetooth signals is shown by a dotted line ellipse X1, namely, bluetooth communication connection between the Bluetooth equipment and other equipment is realized through the Bluetooth signals radiated by the main antenna 1, and when the other equipment is located at the W1 position in the figure, the signal intensity of the Bluetooth communication between the Bluetooth equipment and the other equipment is better, so that better Bluetooth communication can be ensured.

As shown in fig. 2, the bluetooth headset includes a main board for setting the bluetooth chip 5, and an antenna stand 10 is disposed on the main board 10, where the antenna stand 10 is of a non-conductive structure, for example, may be a plastic carrier.

The radiation direction of bluetooth earphone accessible earthing switch adjustment bluetooth signal to guarantee the bluetooth communication quality of other bluetooth equipment (e.g. cell-phone) and bluetooth earphone better, promote user's use experience.

In an exemplary embodiment, a bluetooth signal control method is provided and applied to a first bluetooth device, where the first bluetooth device may be a bluetooth device as described above. Referring to fig. 5, the method includes:

s110, under the first stable state, the antenna unit of the first Bluetooth device controls the state of the parasitic antenna in the antenna unit according to the set intensity value and the first intensity value of the Bluetooth communication signals of the first Bluetooth device and the second Bluetooth device.

Wherein the first bluetooth device may comprise a bluetooth signal emitting device comprising a main antenna and a parasitic antenna. The antenna unit of the first bluetooth device includes a main antenna and a parasitic antenna. In the first stable state, the parasitic antenna may be stably in the first state or may be stably in the second state. That is, the parasitic antenna is stably in any one of the first state and the second state, and the bluetooth device determines whether to change the state of the parasitic antenna according to the set intensity value and the first intensity value, so that the radiation direction of the bluetooth signal meets the bluetooth communication requirement, the quality of the bluetooth communication signal is ensured, the user requirement is better met, and the use experience of the user is improved.

The set intensity value can be set before the first Bluetooth device leaves the factory or after the first Bluetooth device leaves the factory, and the set intensity value can be modified to better meet the requirements of users. The set intensity value is used for judging whether the intensity of Bluetooth communication signals of the first Bluetooth device and the second Bluetooth device meets the communication requirement.

Example 1 in the case of the use of the heat-sensitive material,

the first Bluetooth device is a Bluetooth headset, and the second Bluetooth device is a mobile phone. The antenna unit of the Bluetooth headset is in a first stable state, and the parasitic antenna is in a second state.

In this example, under the antenna element of bluetooth headset was in first steady state, if bluetooth headset and mobile phone's bluetooth communication signal's first intensity value is less than or equal to the settlement intensity value, then indicate that bluetooth headset and mobile phone's bluetooth communication signal's intensity value is less, both bluetooth communication quality is weaker, then need switch bluetooth headset's parasitic antenna under to first state, with the radiation orientation of change bluetooth headset transmission bluetooth signal, with the bluetooth communication quality that promotes bluetooth headset and mobile phone, satisfy bluetooth communication demand better, promote user experience.

In the Bluetooth signal control method, the strength of the Bluetooth communication signals of the first Bluetooth device and the second Bluetooth device is judged by setting the set strength value, and then the radiation direction of the Bluetooth signals of the first Bluetooth device is adjusted by controlling the state of the parasitic antenna, so that the strength of the Bluetooth communication signals of the first Bluetooth device and the second Bluetooth device is adjusted, the Bluetooth communication requirements are better met, and the user experience is improved.

In one exemplary embodiment, a bluetooth signal control method is provided for use with a first bluetooth device. In the method, when the antenna unit of the first bluetooth device is in a first stable state, according to a set intensity value and a first intensity value of bluetooth communication signals of the first bluetooth device and the second bluetooth device, controlling the state of the parasitic antenna may include:

S210, determining a first intensity value every time a first set duration is set when the antenna unit is in a first stable state;

s220, controlling the state of the parasitic antenna according to the set intensity value and the first intensity value.

In step S210, the first set duration may be set before the first bluetooth device leaves the factory, or may be set after the first bluetooth device leaves the factory, and after the first set duration is set, the first set duration may be modified, so as to better meet different requirements of users. The first set duration is used for controlling the determining period of the first intensity value, so that the first intensity value is prevented from being determined too frequently, and the energy consumption of the first Bluetooth device can be reduced.

In this step, from the time when the antenna unit enters the first stable state, the timing is started, and every time a first set period of time is set, the strength value of the bluetooth communication signal between the first bluetooth device and the second bluetooth device is detected once, so as to determine the first strength value. The first set duration may be 1 second, 2 seconds, or 3 seconds.

The setting of the first set duration can avoid that the first Bluetooth device frequently detects the intensity of Bluetooth communication signals and influences the reliability of Bluetooth communication, and the setting of the first set duration can also reduce the energy consumption of the first Bluetooth device.

In step S220, after the first intensity value is determined each time, the quality of bluetooth communication between the first bluetooth device and the second bluetooth device can be determined based on the first intensity value determined this time and the preset set intensity value, and when the bluetooth communication quality is poor, the radiation direction of the bluetooth signal of the first bluetooth device can be adjusted in time by adjusting the state of the parasitic antenna, so as to adjust the bluetooth communication quality of the first bluetooth device and the second bluetooth device, and further improve the use experience of the user.

Example 1 in the case of the use of the heat-sensitive material,

the first Bluetooth device is a Bluetooth headset, the second Bluetooth device is a mobile phone, and the first set duration is 3 seconds.

The intensity detection unit of the Bluetooth communication signal of the Bluetooth headset detects intensity values of the Bluetooth communication signals of the Bluetooth headset and the mobile phone every 3 seconds, and transmits the detected intensity values to the processor of the Bluetooth headset so that the processor can determine the first intensity value.

After the first intensity value is determined by the processing of the Bluetooth headset, the intensity value is convenient to set for comparison. If the first intensity value is larger than the set intensity value, the Bluetooth communication quality between the Bluetooth headset and the mobile phone is good, and the state of the parasitic antenna in the Bluetooth headset does not need to be adjusted. If the first intensity value is smaller than or equal to the set intensity value, the Bluetooth communication quality between the Bluetooth headset and the mobile phone is poor, the mobile phone is not in the current radiation direction of the Bluetooth signal sent by the Bluetooth headset, the state of the parasitic antenna can be adjusted, the radiation direction of the Bluetooth signal sent by the Bluetooth headset is changed, so that the Bluetooth communication quality between the Bluetooth headset and the mobile phone is improved, and the user experience is improved.

According to the method, the first set duration is set, so that the first Bluetooth device can be prevented from frequently detecting the intensity of Bluetooth communication signals and affecting the reliability of Bluetooth communication, the first set duration is set, the energy consumption of the first Bluetooth device can be reduced, and the use experience of a user is further improved.

In one exemplary embodiment, a bluetooth signal control method is provided for use with a first bluetooth device. In the method, controlling the state of the parasitic antenna according to the set intensity value and the first intensity value may include:

s310, judging whether the first intensity value is larger than a set intensity value or not; if yes, executing step S320; otherwise, step S330 is performed;

s320, controlling the antenna unit to be in a first stable state;

s330, controlling the antenna unit to be in a detection state, wherein the state of the parasitic antenna in the detection state is different from the state of the parasitic antenna in the first stable state;

s340, determining a second intensity value of Bluetooth communication signals of the first Bluetooth device and the second Bluetooth device when the antenna unit is in a detection state;

s350, controlling the state of the parasitic antenna according to the set intensity difference value, the first intensity value and the second intensity value.

And after each time a new first intensity value is determined, judging the magnitude relation between the first intensity value and the set intensity value so as to determine the quality of Bluetooth communication between the first Bluetooth device and the second Bluetooth device.

If the first intensity value is larger than the set intensity value, the Bluetooth communication quality between the first Bluetooth device and the second Bluetooth device is good, the state of the parasitic antenna is not required to be adjusted, and the antenna unit can be controlled to be in the current stable state continuously, namely the parasitic antenna is controlled to be in the current state continuously. Then, after a first set period of time, a new first intensity value is determined again, compared again with the set intensity value, and so on. That is, if the first intensity value is greater than the set intensity value, the current situation is maintained unchanged, the first intensity value is determined circularly by taking the first set duration as an interval period, and the new first intensity value and the set intensity value are judged, so that the quality of Bluetooth communication between the first Bluetooth device and the second Bluetooth device is known in time.

If the first intensity value is smaller than or equal to the set intensity value, it indicates that the Bluetooth communication quality between the first Bluetooth device and the second Bluetooth device is poor, and it indicates that the second Bluetooth device is not in the radiation range of the Bluetooth signal of the first Bluetooth device, then it indicates that the state of the parasitic antenna may need to be adjusted so as to adjust the radiation direction of the Bluetooth signal of the first Bluetooth device, and then adjust the Bluetooth communication quality between the first Bluetooth device and the second Bluetooth device, so as to better ensure that the Bluetooth communication quality of the first Bluetooth device and the second Bluetooth device is continuously in a better state, and improve the use experience of a user.

In step S330, after determining that the first intensity value is less than or equal to the set intensity value, the antenna unit may be controlled to be in a detection state, where the state of the parasitic antenna in the detection state is different from the state of the parasitic antenna in the first stable state. For example, if the state of the parasitic antenna is the first state in the first stable state, the state of the parasitic antenna is the second state in the detection state. If the state of the parasitic antenna is the second state in the first stable state, the state of the parasitic antenna is the first state in the detection state.

In step S340, after the antenna unit is in the detection state, the intensity value of the bluetooth communication signal between the first bluetooth device and the second bluetooth device in the detection state can be determined, and the intensity value can be recorded as a second intensity value.

In step S350, after the state adjustment of the parasitic antenna is determined based on the set intensity difference value, the first intensity value and the second intensity value, the quality of bluetooth communication between the first bluetooth device and the second bluetooth device is determined, so as to better control the state of the parasitic antenna, and meet the requirement of the user on bluetooth communication quality.

The set intensity difference value can be set before or after the first Bluetooth device leaves the factory, and can be modified later after the set intensity difference value is set, so that the requirements of users are better met.

In this step, the set intensity difference is an improvement difference required to be achieved in bluetooth communication quality between the first bluetooth device and the second bluetooth device, which is set by the user after the state of the parasitic antenna is adjusted. If the required improved difference value of the Bluetooth communication quality between the first Bluetooth device and the second Bluetooth device is not reached after the state adjustment of the parasitic antenna is determined based on the set intensity difference value, the first intensity value and the second intensity value, the parasitic antenna can be controlled to be in the first stable state continuously. Otherwise, the state of the parasitic antenna may be adjusted.

Example 1 in the case of the use of the heat-sensitive material,

the intensity difference is set to d. In the first stable state, the parasitic antenna is in the second state. In a first stable state of the antenna element, a first intensity value D1 is determined. In the detection state of the antenna device (i.e. the parasitic antenna is in the first state), the second intensity value is determined to be D2.

If the second intensity value D2 is smaller than or equal to the sum of the first intensity value D1 and the set intensity difference D, it indicates that after the state of the parasitic antenna is adjusted, the bluetooth communication quality between the first bluetooth device and the second bluetooth device does not reach the required improved difference, and the parasitic antenna is controlled to be in a state corresponding to the first stable state, that is, the parasitic antenna is controlled to be in the second state, so that the antenna unit is in the first stable state.

In this example, if the second intensity value D2 is greater than the sum of the first intensity value D1 and the set intensity difference D, which indicates that the state of the parasitic antenna is adjusted, the bluetooth communication quality between the first bluetooth device and the second bluetooth device reaches the required improved difference, and the adjustable antenna unit is no longer in the first stable state, that is, the controllable parasitic antenna is in the first state.

In the method, when the first intensity value is larger than the set intensity value, the antenna unit can be controlled to be in a first stable state continuously, and periodic detection and judgment are carried out in a first set duration. When the first intensity value is smaller than or equal to the set intensity value, after the state adjustment of the parasitic antenna can be determined under the detection state, the improvement condition of Bluetooth communication quality between the first Bluetooth device and the second Bluetooth device is improved, and then the state of the parasitic antenna is controlled based on the improvement condition, so that the user requirement is better met, and the use experience of a user is further improved.

It should be noted that, in the method, after determining the second strength value of the bluetooth communication signals of the first bluetooth device and the second bluetooth device, the antenna unit may be controlled to be in the first stable state. That is, after the second intensity value in the detection state is determined, the state of the parasitic antenna can be adjusted back to the original state.

In general, the switching unit needs a shorter time period for completing the switching, that is, the parasitic antenna needs a shorter time period for completing the switching of the state, and the processing of the first bluetooth device completes the data processing of the set intensity difference value, the first intensity value and the second intensity value, which needs a worse time period. Thus, after the first bluetooth device determines the second strength value, the state of the parasitic antenna may be adjusted back to the original state.

For example, the antenna element is in a first stable state and the parasitic antenna is in a second state. The data processing duration of the processor is t1 (e.g., 2 seconds), and the duration required for the state adjustment of the parasitic antenna is t2 (e.g., 0.1 seconds). Then, after the second intensity value is determined, the state of the parasitic antenna can be firstly adjusted back to the second state, after the processor finishes data processing, whether the switch needs to adjust the state of the parasitic antenna is determined based on the processing results of the set intensity difference value, the first intensity value and the second intensity value, so that the quality of Bluetooth communication between the first Bluetooth device and the second Bluetooth device is prevented from being in a worse state within the duration t1 of the data processing, and the use experience of a user is further improved.

In addition, after the second intensity value is determined, whether the state of the parasitic antenna needs to be adjusted back to the original state (that is, the state of the parasitic antenna when the antenna unit is in the first stable state) may be determined according to the data processing capability of the processor, or if the data processing time is shorter, the parasitic antenna does not need to be adjusted back to the original state, and instead, whether the switch needs to adjust the state of the parasitic antenna is determined based on the processing result of the set intensity difference value, the first intensity value and the second intensity value. The setting can be flexibly determined according to practical situations, and is not limited herein.

In one exemplary embodiment, a bluetooth signal control method is provided for use with a first bluetooth device. In the method, controlling the state of the parasitic antenna according to the set intensity difference, the first intensity value and the second intensity value may include S410, determining whether the difference between the second intensity value and the first intensity value is greater than the set intensity difference; if yes, executing step S420; otherwise, step S430 is performed;

s420, controlling the antenna unit to be in a second stable state, wherein the second stable state is different from the first stable state;

s430, controlling the antenna unit to be in a first stable state.

In step S410, a difference may be obtained by subtracting the first intensity value from the second intensity value, where the difference is an actual improvement difference of bluetooth communication quality between the first bluetooth device and the second bluetooth device after the adjustment of the state of the parasitic antenna.

If the difference is smaller than or equal to the set intensity difference, it indicates that the bluetooth communication quality between the first bluetooth device and the second bluetooth device does not reach the set improvement difference after the state of the parasitic antenna is adjusted, and the improvement requirement cannot be met, step S430 is executed. If the difference is greater than the set intensity difference, it indicates that the bluetooth communication quality between the first bluetooth device and the second bluetooth device reaches the set improvement difference after the state of the parasitic antenna is adjusted, and the improvement requirement can be met, and step S420 is executed.

In step S420, if the actual improvement difference reaches the set strength difference, which indicates that the bluetooth communication quality between the first bluetooth device and the second bluetooth device is greatly improved after the state of the parasitic antenna is adjusted, the parasitic antenna is controlled to be maintained in the adjusted state, and the antenna unit is in the second stable state in the state. That is, the antenna unit is controlled to be in the second stable state so as to improve the bluetooth communication quality.

Wherein the second steady state is different from the first steady state. If the parasitic antenna is in the first stable state, the parasitic antenna is in the second stable state. If the parasitic antenna is in the second state in the first stable state, the parasitic antenna is in the first state in the second stable state.

In step S430, if the actual improvement difference is smaller than or equal to the set intensity difference, after the state adjustment of the parasitic antenna is described, the improvement or even the deterioration of the bluetooth communication quality between the first bluetooth device and the second bluetooth device is limited, so that the antenna unit can be controlled to be in the first stable state to avoid unnecessary switching.

Example 1 in the case of the use of the heat-sensitive material,

the intensity difference is set to d. The antenna unit is in a first stable state and the parasitic antenna is in a second state. In a first stable state of the antenna element, a first intensity value D1 is determined. And determining that the second intensity value is D2 when the antenna unit is in the detection state (namely, the parasitic antenna is in the first state).

If the difference obtained by subtracting the first intensity value D1 from the second intensity value D2 is smaller than or equal to the set intensity difference D, which indicates that the state of the parasitic antenna is adjusted, the bluetooth communication quality between the first bluetooth device and the second bluetooth device does not reach the required improved difference, the parasitic antenna can be controlled to be in a state corresponding to the first stable state, that is, the parasitic antenna is controlled to be in the second state, so that the antenna unit is in the first stable state.

In this example, if the difference obtained by subtracting the first intensity value D1 from the second intensity value D2 is greater than the set intensity difference D, which indicates that the state of the parasitic antenna is adjusted, after the bluetooth communication quality between the first bluetooth device and the second bluetooth device reaches the required improved difference, the parasitic antenna may be adjusted not to be in the second state any more, that is, the parasitic antenna is controlled to be in a state corresponding to the second stable state (i.e., the first state), so that the antenna unit is in the second stable state.

According to the method, the difference value between the second intensity value and the first intensity value is firstly determined, and then according to the difference value and the set intensity difference value, after the state adjustment of the parasitic antenna is determined, whether the Bluetooth communication quality between the first Bluetooth device and the second Bluetooth device is better improved or not is determined, so that the state of the parasitic antenna is further controlled, the quality of Bluetooth communication between the first Bluetooth device and the second Bluetooth device can be ensured, frequent state switching of the parasitic antenna can be better avoided, and the use experience of a user is further improved.

In one exemplary embodiment, a bluetooth signal control method is provided for use with a first bluetooth device. The method may include:

s510, determining switching times, wherein the antenna unit is switched from a first stable state to a second stable state, and then is switched from the second stable state back to the first stable state, and the switching is recorded as one-time switching;

and S520, stopping the adjustment of the state of the parasitic antenna if the switching times are greater than or equal to the set times.

In step S510, when the control antenna unit enters the detection state, the state of the parasitic antenna needs to be adjusted, but the state after this adjustment is not the stable state of the antenna unit, and therefore, this adjustment of the state of the parasitic antenna does not belong to the switching of the antenna unit from the first stable state to the second stable state or from the second stable state to the first stable state.

In the process of switching the antenna unit from the first stable state to the second stable state, other states can be included. That is, switching the antenna element from the first stable state to the second stable state may include switching the first stable state directly to the second stable state, or switching the first stable state to at least one other state before switching to the second stable state.

The process of switching the antenna unit from the first stable state to the second stable state is similar to the process of switching the antenna unit from the first stable state to the second stable state, and will not be described herein.

Example 1 in the case of the use of the heat-sensitive material,

referring to fig. 6, the first bluetooth device is a bluetooth headset, and the second bluetooth device is a mobile phone. The antenna unit of the Bluetooth headset is in a first stable state, and the parasitic antenna is in a second state. The antenna unit is in a second stable state and the parasitic antenna is in a first state. The antenna unit is in a first detection state, and the parasitic antenna is in a first state. The antenna unit is in a second detection state, and the parasitic antenna is in a second state.

In this example, at a first moment, the antenna unit of the bluetooth headset is in a first stable state (i.e. the parasitic antenna is in a second state), an intensity value of a bluetooth communication signal between the bluetooth headset and the mobile phone is determined, where the intensity value is denoted as a first intensity value D11, and the first intensity value D11 is less than or equal to a set intensity value D0, so that the parasitic antenna is switched from the second state to the first state, and the antenna unit is determined to be in a first detection state.

The antenna unit is in a first detection state (namely the parasitic antenna is in a first state), the intensity value of a Bluetooth communication signal between the Bluetooth earphone and the mobile phone is determined, the intensity value is recorded as a second intensity value D21, the difference value between the second intensity value D21 and the first intensity value D11 is larger than a set intensity difference value D, the parasitic antenna can be controlled to be in the first state, and the antenna unit is determined to be in a second stable state.

At a second moment, the antenna unit is in a second stable state (i.e. the parasitic antenna is in a first stable state), the intensity value of the Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined, the intensity value is recorded as a first intensity value D12, the first intensity value D12 is smaller than or equal to a set intensity value D0, the parasitic antenna is switched to a second state, and the antenna unit is determined to be in a second detection state.

The antenna unit is in a second detection state (namely the parasitic antenna is in a second state), the intensity value of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined, the intensity value is recorded as a second intensity value D22, the difference value between the second intensity value D22 and the first intensity value D12 is larger than the set intensity difference value D, the parasitic antenna can be controlled to be in the second state, and the antenna unit is determined to be in a first stable state.

So far, the Bluetooth headset completes one switching, and the switching times are increased by 1 time.

Example 2 in the case of the use of the heat-sensitive material,

The antenna unit is in a first detection state, the intensity value of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined, and the intensity value is recorded as a second intensity value D21. After determining the second intensity value D21, the parasitic antenna may be switched back to the second state.

Then, it is determined whether the difference between the second intensity value D21 and the first intensity value D11 is greater than the set intensity difference D. If the difference between the second intensity value D21 and the first intensity value D11 is greater than the set intensity difference D, the parasitic antenna is switched to the first state, and the antenna unit is determined to be in the second stable state.

At a second moment, the antenna unit is in a second stable state, the intensity value of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined, the intensity value is recorded as a first intensity value D12, the first intensity value D12 is smaller than or equal to a set intensity value D0, the parasitic antenna is switched to a second state, and the antenna unit is determined to be in a second detection state.

And when the antenna unit is in the second detection state, determining the intensity value of a Bluetooth communication signal between the Bluetooth headset and the mobile phone, wherein the intensity value is recorded as a second intensity value D22. After determining the second intensity value D21, the parasitic antenna may be switched back to the first state.

Then, it is determined whether the difference between the second intensity value D22 and the first intensity value D12 is greater than the set intensity difference D. If the difference between the second intensity value D22 and the first intensity value D12 is greater than the set intensity difference D, the parasitic antenna is switched to the second state, and the antenna unit is determined to be in the first stable state.

In step S520, the setting times may be set before the first bluetooth device leaves the factory, or may be set after the first bluetooth device leaves the factory, and after the setting of the setting times is completed, the setting times may be modified, so as to better meet different requirements of users. The setting number is set according to actual needs, and for example, the setting number may be 5 times, 10 times, 13 times, or the like, which is not limited herein.

When the accumulated switching times are greater than or equal to the set times, the states of the antenna units are switched between the first stable state and the second stable state too frequently, the states of the parasitic antennas are switched too frequently, and whether the parasitic antennas are in the first state or the second state, bluetooth communication signals between the first Bluetooth equipment and the second Bluetooth equipment are not stable enough, and the states of the parasitic antennas can be stopped without frequent adjustment. So as to avoid the influence caused by frequent switching of the state of the parasitic antenna due to unstable Bluetooth communication signals.

Wherein stopping the adjustment of the state of the parasitic antenna may include: the set intensity difference is switched from a first value to a second value, and the second value is greater than the first value. That is, in the method, the set intensity difference is lifted to avoid frequent switching of the antenna unit between the first stable state and the second stable state, so as to avoid frequent switching of the parasitic antenna between the first state and the second state.

The "stop adjustment of the state of the parasitic antenna" may be achieved by other means, and is not limited thereto.

In this method, the time can be counted after the adjustment of the state of the parasitic antenna is stopped. If the duration of the stop is longer than the second set duration (for example, 10 seconds, 20 seconds, etc.), the adjustment of the state of the parasitic antenna can be restarted, so that the influence caused by frequent switching of the state of the parasitic antenna due to unstable Bluetooth communication signals can be avoided, the quality of Bluetooth communication between the first Bluetooth device and the second Bluetooth device can be better ensured, and the use experience of a user is improved.

According to the method, the influence caused by frequent switching of the parasitic antenna between the first state and the second state can be better avoided by setting the set times, the energy consumption of the first Bluetooth device can be reduced, and the use experience of a user is further improved.

In one exemplary embodiment, a bluetooth signal control method is provided for use with a first bluetooth device. The method may include: the default state of the parasitic antenna is the second state. In general, the default state is the stable second state.

Example 1 in the case of the use of the heat-sensitive material,

the first Bluetooth device is a Bluetooth headset, the second Bluetooth device is a mobile phone, the first set duration is 3 seconds, the set intensity value is D0, the set times are 10 times, and the set intensity difference value comprises a first value D1 and a second value D2, wherein the second value D2 is larger than the first value D1.

The Bluetooth headset comprises a main antenna and a parasitic antenna, wherein the main antenna is close to a loudspeaker of the Bluetooth headset, the parasitic antenna is far away from the loudspeaker, and the wiring directions of the main antenna and the parasitic antenna are set.

Referring to fig. 1, in the bluetooth headset, when the ground switch is in the contact a, it is in the off state, the parasitic antenna is not grounded, and the parasitic antenna is in the second state. Under this condition, the feeding unit can apply the first current to the main antenna through the contact C, and only the main antenna radiates the bluetooth signal, the radiation direction of the bluetooth signal is shown as a dashed ellipse X1 in fig. 1, that is, the bluetooth device realizes the bluetooth communication connection with other devices through the bluetooth signal radiated by the main antenna, and when the other devices are located at the W1 position in fig. 1, the signal strength of the bluetooth communication between the main antenna and the bluetooth device is better, so that better bluetooth communication can be ensured.

When the grounding switch is in the contact B, which is in the closed state, the parasitic antenna is grounded, and the parasitic antenna is in the first state. Under the condition, the feeding unit can apply a second current to the main antenna through the contact D, the main antenna and the parasitic antenna both radiate Bluetooth signals, and the Bluetooth signals radiated by the parasitic antenna and the Bluetooth signals radiated by the main antenna mutually influence each other, so that the whole radiation of the Bluetooth signal transmitting device is shown as a broken line ellipse X2 in fig. 1, namely, the Bluetooth device realizes Bluetooth communication connection with other devices through the Bluetooth signals jointly radiated by the main antenna and the parasitic antenna, and when the other devices are positioned at a W2 position in fig. 1, the signal intensity of the Bluetooth communication of the main antenna and the parasitic antenna is better, and better Bluetooth communication can be ensured.

The antenna unit is in a first stable state and the parasitic antenna is in a second state. The antenna unit is in a second stable state and the parasitic antenna is in a first state. When the antenna unit is in the first detection state, the parasitic antenna is in the first state. When the antenna unit is in the second detection state, the parasitic antenna is in the second state.

In this example, after the bluetooth communication function of the bluetooth headset is turned on, the ground switch is defaulted to be at contact a, the parasitic antenna is in the second state, and the antenna unit is determined to be in the first stable state. After the Bluetooth communication connection is established between the Bluetooth headset and the mobile phone, the set intensity difference value defaults to a first value d1.

The antenna unit of the Bluetooth headset is in a first stable state, the strength detection unit of the Bluetooth communication signal of the Bluetooth headset detects the strength value of the Bluetooth communication signal of the Bluetooth headset and the Bluetooth communication signal of the mobile phone every 3 seconds, and the detected strength value is transmitted to the processor of the Bluetooth headset, so that the processor determines the first strength value.

At a first moment, a first intensity value D11 of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined.

If the first intensity value D11 is greater than the set intensity value D0, the grounding switch is maintained at the contact a, so that the parasitic antenna is kept in the second state, that is, the antenna unit is kept in the first stable state, and the intensity value of the bluetooth communication signal between the bluetooth headset and the mobile phone is continuously detected every 3 seconds, and the subsequent actions are performed.

If the first intensity value D11 is smaller than or equal to the set intensity value D0, the grounding switch is switched to the contact B, so that the parasitic antenna is in the first state, and the antenna unit is determined to be switched to the first detection state.

The antenna unit is in the first detection state, and a second intensity value D21 of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined.

If the difference between the second intensity value D21 and the first intensity value D11 is smaller than or equal to the first value D1, the grounding switch can be switched to the contact a, so that the parasitic antenna returns to the second state, the antenna unit is determined to return to the first stable state, the intensity values of the Bluetooth communication signals of the Bluetooth headset and the mobile phone are continuously detected every 3 seconds, and the follow-up actions are performed.

If the difference between the second intensity value D21 and the first intensity value D11 is greater than the first value D1, the grounding switch is kept at the contact B, so that the parasitic antenna is in the first state, and the antenna unit is determined to be switched to the second stable state.

The antenna unit is in the second stable state, the intensity detection unit of the Bluetooth communication signal of the Bluetooth headset detects the intensity value of the Bluetooth communication signal of the Bluetooth headset and the Bluetooth communication signal of the mobile phone every 3 seconds, and transmits the detected intensity value to the processor of the Bluetooth headset, so that the processor determines the first intensity value.

At a second moment, a first intensity value D12 of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined.

If the first intensity value D12 is greater than the set intensity value D0, the grounding switch is maintained at the contact B, so that the parasitic antenna is in the first state, the antenna unit is determined to be in the second stable state, and the intensity value of the bluetooth communication signal between the bluetooth headset and the mobile phone is continuously detected every 3 seconds, and the subsequent actions are performed.

If the first intensity value D12 is smaller than or equal to the set intensity value D0, the grounding switch is switched to the contact a, so that the parasitic antenna is switched to the second state, and the antenna unit is determined to be switched to the second detection state.

And the antenna unit is in a second detection state, and a second intensity value D22 of a Bluetooth communication signal between the Bluetooth headset and the mobile phone is determined.

If the difference between the second intensity value D22 and the first intensity value D12 is smaller than or equal to the first value D1, the grounding switch is switched to the contact B, so that the parasitic antenna returns to the first state, the antenna unit is determined to return to the second stable state, and the intensity values of the bluetooth communication signals of the bluetooth headset and the mobile phone are continuously detected every 3 seconds, and the subsequent actions are performed.

If the difference between the second intensity value D22 and the first intensity value D12 is greater than the first value D1, the grounding switch is maintained at the contact B, so that the parasitic antenna is in the second state, and it is determined that the antenna unit is switched to the first stable state. So far, the Bluetooth headset completes one switching, and the switching times are increased by 1 time.

And under the condition that the antenna unit is switched to the first stable state, continuously detecting the intensity value of the Bluetooth communication signal of the Bluetooth headset and the mobile phone every 3 seconds, and performing subsequent actions.

The set intensity difference value can be adjusted to a second value d2 until the switching times reach 10 times, and the difference value between the second intensity value and the first intensity value is always smaller than the second value d2 because the second value d2 is larger than the first value d1, so that the parasitic antenna can be prevented from being frequently switched between the first state and the second state.

After the set intensity difference is adjusted to the second value d2, the duration is recorded at the same time. And the set intensity difference value can be adjusted back to the first value d1 until the duration is longer than or equal to the second set duration, so that the adjustment of the state of the parasitic antenna is continued, the control of Bluetooth signals is realized, the Bluetooth communication quality between the Bluetooth earphone and the mobile phone is ensured, and the use experience of a user is further improved.
