Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the present application.

In order to explain the technical solutions of the present application, the following detailed descriptions are made with reference to specific drawings and examples.

When the existing Bluetooth headset is used, signals are transmitted by establishing Bluetooth connection between a main headset and terminal equipment, and signals are transmitted by establishing Bluetooth connection between the main headset and a slave headset. When the master earphone and the slave earphone transmit signals, the signals of the master earphone and the slave earphone generally need to be diffracted and propagated around the head of a user, so that the signals are attenuated, and the performance of the earphone antenna in the horizontal direction is tested very much; when the main earphone and the terminal device transmit signals, the signals need to bypass the body of a user to be transmitted, and the signals are also attenuated, so that the performance of the earphone antenna in the vertical direction is very tested. Because the existing bluetooth headset adopts a single antenna structure, the transmission of the antenna has directivity. Therefore, the antenna can only be used for transmission in two directions in a compromise manner, so that the bluetooth headset cannot reach an optimal state in signal transmission between the master headset and the terminal device and between the master headset and the slave headset, and the bluetooth headset is subjected to phenomena of sound blockage, delay and the like.

In view of the above, the present application provides a method for processing a signal, which is suitable for a bluetooth headset. The bluetooth headset in this application can include main earphone and follow earphone, is provided with horizontal polarization antenna and vertical polarization antenna in main earphone and the follow earphone respectively. The horizontal polarization antenna is an antenna which is arranged in the earphone in the direction close to the horizontal direction in a wearing state, and has excellent transmission and receiving performance on signals transmitted in the horizontal direction; the vertically polarized antenna is an antenna which is arranged in a nearly vertical direction in the earphone in a wearing state, and has excellent transmission and reception performance for signals transmitted in the vertical direction.

Referring to fig. 1, fig. 1 is a schematic flowchart of a method for processing a signal according to an embodiment of the present disclosure. The method for processing signals in the embodiment is performed by a bluetooth headset, including but not limited to a Wireless bluetooth headset, such as a True Wireless Stereo (TWS) headset. The method for processing signals as shown in fig. 1 may be applied to a bluetooth headset, where the bluetooth headset includes a master headset and a slave headset, the master headset is provided with a first horizontally polarized antenna and a first vertically polarized antenna, and the slave headset is provided with a second horizontally polarized antenna and a second vertically polarized antenna, and the method includes steps S101 to S108, which are as follows:

s101: when the master earphone and/or the slave earphone detects a first radio frequency signal sent by the terminal device, a first received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header by a first horizontal polarization antenna and a first vertical polarization antenna and/or a second horizontal polarization antenna and a second vertical polarization antenna is obtained.

In this embodiment, a TWS headset is taken as an example for description, the TWS headset may include a master headset and a slave headset, the master headset is provided with a first horizontally polarized antenna and a first vertically polarized antenna, and the slave headset is provided with a second horizontally polarized antenna and a second vertically polarized antenna. The master earphone and the slave earphone are relatively speaking, the master earphone is firstly connected with the terminal equipment through Bluetooth, the slave earphone is indirectly connected with the terminal equipment through the master earphone, the slave earphone can acquire a first radio frequency signal sent by the terminal equipment in a monitoring mode, and the master earphone can also forward a second radio frequency signal to the slave earphone. The terminal device related in the present application may be a device supporting bluetooth connection, such as a mobile phone, a tablet computer, and a notebook, which is not limited to this.

When the main earphone detects a first radio frequency signal sent by the terminal device, the main earphone obtains a first Received Signal Strength Indication (RSSI) corresponding to a first test signal of a first radio frequency signal packet header by the first horizontal polarization antenna and the first vertical polarization antenna. The terminal adds a packet header to a first radio frequency signal before sending the first radio frequency signal each time, and a first test signal of the first radio frequency signal packet header is used for assisting a main earphone and judging which antenna is selected from the auxiliary earphone to receive the first radio frequency signal. Optionally, in an implementation manner, when the main earphone detects the first radio frequency SIGNAL sent by the terminal device, the main earphone may further obtain a first SIGNAL-to-NOISE RATIO (SNR) of the first horizontal polarization antenna and the first vertical polarization antenna corresponding to the first test SIGNAL in the first radio frequency SIGNAL header, and obtain a first error rate (SER) of the first horizontal polarization antenna and the first vertical polarization antenna corresponding to the first test SIGNAL in the first radio frequency SIGNAL header.

And/or when the earphone detects a first radio frequency signal sent by the terminal equipment, acquiring a first received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header of the second horizontal polarization antenna and the second vertical polarization antenna from the earphone. Optionally, in an implementation manner, when the first radio frequency signal sent by the terminal device is detected by the earphone, the earphone may further obtain a first signal-to-noise ratio corresponding to the first test signal in the first radio frequency signal header by the second horizontal polarization antenna and the second vertical polarization antenna, and obtain a first error rate corresponding to the first test signal in the first radio frequency signal header by the second horizontal polarization antenna and the second vertical polarization antenna.

Illustratively, when the user uses only one of the TWS headsets, the headset is the primary headset at this time. The terminal equipment converts an audio signal to be sent into a first radio frequency signal and then broadcasts the first radio frequency signal, when the main earphone detects the first radio frequency signal, a received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header is obtained based on a first horizontal polarization antenna in the main earphone, and a received signal strength indication corresponding to the first test signal of the first radio frequency signal packet header is obtained based on a first vertical polarization antenna in the main earphone.

Exemplarily, when the main earphone detects a first radio frequency signal sent by the terminal device, the main earphone performs frequency conversion processing on a first test signal in a first radio frequency signal packet head based on a first horizontal polarization antenna in the main earphone, and changes a high-frequency first test signal into a low-frequency signal; the low-frequency signal is an analog signal and is converted into a digital signal; and demodulating the digital signal through a digital signal processing unit in the main earphone to obtain a first received signal strength indication corresponding to a first test signal of the first horizontal polarization antenna to the first radio frequency signal packet header. The same processing method may be adopted to obtain a first received signal strength indication corresponding to a first test signal of the first vertical polarization antenna to the first radio frequency signal packet header. Similarly, the first received signal strength indication corresponding to the first test signal in the first radio frequency signal packet header obtained by the second horizontal polarization antenna and the second vertical polarization antenna from the earphone is not described herein again.

When a user uses two earphones in the TWS earphone at the same time, the earphone which is directly connected with the terminal in a Bluetooth mode is a main earphone, virtual Bluetooth connection is established between the main earphone and the auxiliary earphone, and the auxiliary earphone is indirectly connected with the terminal equipment. Specifically, the terminal device converts an audio signal to be transmitted into a first radio frequency signal and then broadcasts the first radio frequency signal, and the master earphone conveys information of the first radio frequency signal broadcast by the terminal device to the slave earphone while detecting the first radio frequency signal, so that the slave earphone can monitor the first radio frequency signal broadcast by the terminal device. After detecting a first radio frequency signal broadcast by the terminal device, the main earphone acquires a first received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header by the first horizontal polarization antenna and the first vertical polarization antenna. After monitoring a first radio frequency signal sent by the terminal device, the slave earphone acquires a first received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header by the second horizontal polarization antenna and the second vertical polarization antenna.

S102: the main earphone judges that the first horizontally polarized antenna is a first target antenna of a main ear when detecting that a first received signal strength indication corresponding to the first horizontally polarized antenna is greater than or equal to a first received signal strength indication corresponding to the first vertically polarized antenna, and judges that the first vertically polarized antenna is a first target antenna of a main ear when detecting that the first received signal strength indication corresponding to the first horizontally polarized antenna is smaller than the first received signal strength indication corresponding to the first vertically polarized antenna.

The main earphone determines a first target antenna of a main ear according to a first received signal strength indication corresponding to a first test signal of the first radio frequency signal packet header obtained by the first horizontal polarization antenna and the first vertical polarization antenna. The first main-ear target antenna is an antenna for ensuring better signal quality when receiving the first rf signal, and may be a first horizontally polarized antenna or a first vertically polarized antenna.

Illustratively, when the user uses only one of the TWS headphones, through the processing in S101, the received signal strength indication corresponding to the first test signal, in which the first radio frequency signal header is obtained based on the first horizontally polarized antenna in the primary headphone, and the received signal strength indication corresponding to the first test signal, in which the first radio frequency signal header is obtained based on the first vertically polarized antenna in the primary headphone, are obtained. The main earphone compares the two received signal strength indications, and selects an antenna corresponding to the side with the better received signal strength indication as a first target antenna of the main earphone. Specifically, when detecting that a first received signal strength indication corresponding to the first horizontal polarization antenna is greater than or equal to a first received signal strength indication corresponding to the first vertical polarization antenna, the primary earphone determines that the first horizontal polarization antenna is a first target antenna of the primary ear, and when detecting that the first received signal strength indication corresponding to the first horizontal polarization antenna is smaller than the first received signal strength indication corresponding to the first vertical polarization antenna, determines that the first vertical polarization antenna is the first target antenna of the primary ear.

For example, the RSSI corresponding to the first test signal of the first radio frequency signal packet header acquired based on the first horizontal polarization antenna in the main headset is-80 dbm, and the RSSI corresponding to the first test signal of the first radio frequency signal packet header acquired based on the first vertical polarization antenna in the main headset is-60 dbm; the main earpiece compares the magnitudes of the two RSSIs, and it is obvious that the first vertically polarized antenna corresponding to the RSSI of-60 dbm receives the first radio frequency signal better. At this time, the first vertically polarized antenna in the main earphone is taken as the main ear first target antenna.

S103: the slave earphone judges that the second horizontally polarized antenna is a first slave ear target antenna when detecting that a first received signal strength indication corresponding to the second horizontally polarized antenna is larger than or equal to a first received signal strength indication corresponding to the second vertically polarized antenna, and judges that the second vertically polarized antenna is a first slave ear target antenna when detecting that the first received signal strength indication corresponding to the second horizontally polarized antenna is smaller than the first received signal strength indication corresponding to the second vertically polarized antenna.

Illustratively, the slave earphone determines the slave ear first target antenna according to the obtained first received signal strength indication corresponding to the first test signal of the second horizontal polarization antenna and the second vertical polarization antenna to the first radio frequency signal packet header. The first target antenna of the slave ear is an antenna for ensuring better signal quality when receiving the first radio frequency signal, and the first target antenna of the slave ear may be a second horizontally polarized antenna and may also be a second vertically polarized antenna.

Illustratively, the received signal strength indication corresponding to the first test signal obtained from the second horizontally polarized antenna in the headset to the first radio frequency signal header and the received signal strength indication corresponding to the first test signal obtained from the second vertically polarized antenna in the headset to the first radio frequency signal header. The slave earphone compares the two received signal strength indicators and selects the antenna corresponding to the better received signal strength indicator as the first target antenna of the slave ear. Specifically, the slave earphone determines that the second horizontally polarized antenna is the first slave-ear target antenna when detecting that the first received signal strength indication corresponding to the second horizontally polarized antenna is greater than or equal to the first received signal strength indication corresponding to the second vertically polarized antenna, and determines that the second vertically polarized antenna is the first slave-ear target antenna when detecting that the first received signal strength indication corresponding to the second horizontally polarized antenna is smaller than the first received signal strength indication corresponding to the second vertically polarized antenna.

Optionally, in an implementation manner, the slave earphone may determine the first slave ear target antenna according to the obtained first signal-to-noise ratio of the first test signal in the first radio frequency signal packet header by the second horizontally polarized antenna and the second vertically polarized antenna. Specifically, the slave earphone determines that the second horizontally polarized antenna is the first slave ear target antenna when detecting that the first signal-to-noise ratio corresponding to the second horizontally polarized antenna is greater than or equal to the first signal-to-noise ratio corresponding to the second vertically polarized antenna, and determines that the second vertically polarized antenna is the first slave ear target antenna when detecting that the first signal-to-noise ratio corresponding to the second horizontally polarized antenna is less than the first signal-to-noise ratio corresponding to the second vertically polarized antenna.

Optionally, in an implementable manner, the slave earpiece may determine the first slave-ear target antenna according to the obtained first bit error rate corresponding to the first test signal in the packet header of the first radio frequency signal by the second horizontally polarized antenna and the second vertically polarized antenna. Specifically, the slave earphone determines that the second horizontally polarized antenna is the first slave ear target antenna when detecting that the first error rate corresponding to the second horizontally polarized antenna is less than or equal to the first error rate corresponding to the second vertically polarized antenna, and determines that the second vertically polarized antenna is the first slave ear target antenna when detecting that the first error rate corresponding to the second horizontally polarized antenna is greater than the first error rate corresponding to the second vertically polarized antenna.

S104: and when the master earphone detects a slave earphone or the slave earphone detects a second radio frequency signal sent by the master earphone, acquiring a second received signal strength indication corresponding to a second test signal of a second radio frequency signal packet header by the first horizontal polarization antenna and the first vertical polarization antenna or the second horizontal polarization antenna and the second vertical polarization antenna.

The second radio frequency signal may comprise a synchronization signal and/or a repeating signal. The synchronous signal is used for the master earphone and the slave earphone to convert the received first radio frequency signal into an audio signal and then synchronously play the audio signal in the earphones, so that the master earphone and the slave earphone worn by a user synchronously make sound; when the slave earphone needs to forward a signal through the master earphone to receive a first radio frequency signal sent by the terminal device, the master earphone needs to forward the first radio frequency signal to the slave earphone after receiving the first radio frequency signal, and it can be understood that the forwarded signal at this time is the first radio frequency signal received by the master earphone. Illustratively, when the second radio frequency signal is a repeating signal and the slave earphone detects the second radio frequency signal sent by the master earphone, a second received signal strength indication corresponding to a second test signal of a second radio frequency signal packet header by a second horizontal polarization antenna and a second vertical polarization antenna is obtained. And when the second radio-frequency signal is a synchronous signal and the main earphone detects the second radio-frequency signal sent by the slave earphone, acquiring a second received signal strength indication corresponding to a second test signal of a second radio-frequency signal packet header by the first horizontal polarization antenna and the first vertical polarization antenna.

When the second radio frequency signal is a synchronization signal, taking the TWS headset as an example for description, when a user uses two of the TWS headsets simultaneously, after both the master headset and the slave headset receive the first radio frequency signal sent by the terminal device, the master headset sends the synchronization signal to the slave headset. Before the master earphone sends the synchronizing signal, a packet header is added to the synchronizing signal, and at the moment, a second test signal of the packet header of the synchronizing signal is used for assisting the slave earphone in judging which antenna is selected to receive the second radio frequency signal. The synchronous signal is used for the master earphone and the slave earphone to convert the received first radio frequency signal into an audio signal and then synchronously play the audio signal in the earphones, so that the master earphone and the slave earphone worn by a user synchronously make sound.

Illustratively, the master earphone may transmit the synchronization signal to the slave earphone based on an antenna used in signal transmission with the terminal device, may randomly select the first horizontally polarized antenna or the first vertically polarized antenna to transmit the synchronization signal to the slave earphone, and may transmit the synchronization signal to the slave earphone through the first horizontally polarized antenna and the first vertically polarized antenna at the same time. And when the slave earphone detects the synchronous signal sent by the master earphone, acquiring a received signal strength indication corresponding to the second test signal of the head of the synchronous signal packet. Optionally, in an implementation manner, the slave earpiece may further obtain a signal-to-noise ratio of the second horizontal polarization antenna and the second vertical polarization antenna to the second test signal of the synchronization signal header, and obtain an error rate of the second horizontal polarization antenna and the second vertical polarization antenna to the second test signal of the synchronization signal header.

When the second radio frequency signal is a forwarding signal, the TWS headset is taken as an example for explanation, when a user uses two of the TWS headsets at the same time, the terminal device converts an audio signal to be sent into a first radio frequency signal and broadcasts the first radio frequency signal, and the main headset receives the first radio frequency signal based on the first target antenna of the main headset after detecting the first radio frequency signal. The master earphone forwards the received first radio frequency signal to the slave earphone. In particular, the master earphone may divide the first radio frequency signal into a plurality of segments of the second radio frequency signal, which are forwarded to the slave earphone in batches. When the slave earphone detects a second radio frequency signal sent by the master earphone, second receiving signal strength indications corresponding to second test signals of a second horizontal polarization antenna and a second vertical polarization antenna for a second radio frequency signal packet header are obtained, an antenna for receiving the second radio frequency signal is determined based on the respective corresponding second receiving signal strength indications, and the second radio frequency signal is received based on the determined antenna. Meanwhile, the main earphone adjusts the antenna to be the same type of antenna as the auxiliary earphone to forward the rest second radio frequency signals. For example, if the slave earphone receives a second radio frequency signal based on the second horizontally polarized antenna, the master earphone performs signal transmission with the slave earphone based on the first horizontally polarized antenna; and the slave earphone receives a second radio frequency signal based on the second vertical polarization antenna, and the master earphone performs signal transmission with the slave earphone based on the first vertical polarization antenna. For example, when the slave earphone initially receives the second radio frequency signal, a feedback signal may be sent to the master earphone, and the master earphone obtains a received signal strength indication corresponding to the feedback signal and determines which antenna to use to continue forwarding the second radio frequency signal to the slave earphone based on the received signal strength indication. The positions of the master earphone and the slave earphone are opposite, so when the master earphone and the slave earphone transmit signals, the adopted antennas are all antennas in the same direction. Optionally, in an implementation manner, the slave headset may further obtain a signal-to-noise ratio corresponding to a second test signal of the transponder head by the second horizontally polarized antenna and the second vertically polarized antenna, and obtain an error rate corresponding to a second test signal of the transponder head by the second horizontally polarized antenna and the second vertically polarized antenna.

S105: the main earphone judges that the first horizontal polarization antenna is a main ear second target antenna when detecting that a second received signal strength indication corresponding to the first horizontal polarization antenna is larger than or equal to a second received signal strength indication corresponding to the first vertical polarization antenna, and judges that the first vertical polarization antenna is a main ear second target antenna when detecting that the second received signal strength indication corresponding to the first horizontal polarization antenna is smaller than the second received signal strength indication corresponding to the first vertical polarization antenna.

And the main earphone determines a second target antenna of the main ear according to the obtained second received signal strength indication corresponding to the second test signal of the first horizontal polarization antenna and the first vertical polarization antenna to the second radio frequency signal packet head. The second target antenna of the main ear is an antenna for ensuring better signal quality when receiving the second radio frequency signal, and the second target antenna of the main ear may be a first horizontally polarized antenna or a first vertically polarized antenna.

Illustratively, the received signal strength indication corresponding to the second test signal based on the second radio frequency signal header being acquired by the first horizontally polarized antenna in the primary earphone, and the received signal strength indication corresponding to the second test signal based on the second radio frequency signal header being acquired by the first vertically polarized antenna in the primary earphone. The main earphone compares the two received signal strength indications, and selects an antenna corresponding to the side with the better received signal strength indication as a second target antenna of the main earphone. Specifically, the main earphone determines that the first horizontally polarized antenna is the second target antenna of the main ear when detecting that the second received signal strength indication corresponding to the first horizontally polarized antenna is greater than or equal to the second received signal strength indication corresponding to the first vertically polarized antenna, and determines that the first vertically polarized antenna is the second target antenna of the main ear when detecting that the second received signal strength indication corresponding to the first horizontally polarized antenna is smaller than the second received signal strength indication corresponding to the first vertically polarized antenna.

S106: the slave earphone judges that the second horizontally polarized antenna is a second slave ear target antenna when detecting that a second received signal strength indication corresponding to the second horizontally polarized antenna is larger than or equal to a second received signal strength indication corresponding to the second vertically polarized antenna, and judges that the second vertically polarized antenna is a second slave ear target antenna when detecting that the second received signal strength indication corresponding to the second horizontally polarized antenna is smaller than the second received signal strength indication corresponding to the second vertically polarized antenna.

And the slave earphone determines a second target antenna of the slave ear according to the obtained second received signal strength indication corresponding to the second test signal of the second radio frequency signal packet head by the second horizontal polarization antenna and the second vertical polarization antenna. The second target antenna of the slave ear is an antenna for ensuring better signal quality when receiving the second radio frequency signal, and the second target antenna of the slave ear may be a second horizontally polarized antenna or a second vertically polarized antenna.

Illustratively, the received signal strength indication corresponding to the second test signal obtained from the second horizontally polarized antenna in the headset to the second radio frequency signal header and the received signal strength indication corresponding to the second test signal obtained from the second vertically polarized antenna in the headset to the second radio frequency signal header. The slave earphone compares the two received signal strength indicators and selects the antenna corresponding to the better received signal strength indicator as the second target antenna of the slave earphone. Specifically, the slave earphone determines that the second horizontally polarized antenna is the second target antenna from the ear when detecting that the second received signal strength indication corresponding to the second horizontally polarized antenna is greater than or equal to the second received signal strength indication corresponding to the second vertically polarized antenna, and determines that the second vertically polarized antenna is the second target antenna from the ear when detecting that the second received signal strength indication corresponding to the second horizontally polarized antenna is less than the second received signal strength indication corresponding to the second vertically polarized antenna.

S107: the primary earpiece receives a first radio frequency signal based on the primary ear first target antenna and a second radio frequency signal based on the primary ear second target antenna.

The main earphone receives a first radio frequency signal based on the first target antenna of the main ear and receives a second radio frequency signal based on the second target antenna of the main ear. Exemplarily, if the first target antenna of the main ear determined by the main earphone in S102 is the first horizontally polarized antenna, the first radio frequency signal sent by the terminal device is received based on the first horizontally polarized antenna in the main earphone; if the first target antenna of the main ear determined by the main earphone in S102 is the first vertical polarization antenna, the first radio frequency signal sent by the terminal device is received based on the first vertical polarization antenna in the main earphone.

Exemplarily, when the second radio frequency signal is a synchronization signal, if the second target antenna of the main ear determined by the main earphone in S105 is the first horizontally polarized antenna, the synchronization signal transmitted from the earphone is received based on the first horizontally polarized antenna in the main earphone; if the second target antenna of the primary ear determined by the primary ear determining unit in S105 is the first vertical polarization antenna, the synchronization signal sent from the secondary ear is received based on the first vertical polarization antenna in the primary ear.

The slave earpiece is based on receiving a first radio frequency signal from the first target antenna of the ear and on receiving a second radio frequency signal from the second target antenna of the ear. Exemplarily, if the slave ear first target antenna determined in S103 by the slave earphone is the second horizontally polarized antenna, the first radio frequency signal is received based on the second horizontally polarized antenna in the slave earphone; if the slave headset determines in S103 that the first target antenna of the slave ear is the second vertically polarized antenna, the first radio frequency signal is received based on the second vertically polarized antenna in the slave headset.

In the above manner, the master earphone and the slave earphone of the bluetooth earphone are respectively provided with two antennas in different directions, and the appropriate antennas can be selected to receive the radio frequency signals according to different received signal strength indications corresponding to different radio frequency signals, so that the real-time reception of the radio frequency signals can be ensured, and the received radio frequency signals are all of optimal signal quality, so that the signal transmission between the master earphone and the terminal equipment and between the master earphone and the slave earphone can be in an optimal state, and the phenomena of sound blockage, delay and the like of the bluetooth earphone are avoided.

Optionally, in some possible implementations of the present application, as shown in fig. 2, fig. 2 is a schematic flowchart of a method for processing a signal according to another embodiment of the present application, where the method may include: s201 to S209. For reference, the steps S201 to S208 shown in fig. 2 may refer to the above description of S101 to S108, and for brevity, the description is omitted here. Step S209 will be specifically explained below.

S209: and the main earphone sends a response signal to the terminal equipment through the first target antenna of the main earphone.

After the second radio frequency signal transmission between the master earphone and the slave earphone is completed, the master earphone needs to send a response signal to the terminal device, and the response signal is used for prompting that the terminal device can send a new radio frequency signal. And the main earphone sends a response signal to the terminal equipment through the first target antenna of the main earphone.

The master earphone detects whether an antenna used for signal transmission between the master earphone and the slave earphone is the same as an antenna used for signal transmission between the master earphone and the terminal equipment, namely, the master earphone detects whether an antenna used for second radio frequency signal transmission between the master earphone and the slave earphone and an antenna used for first radio frequency signal transmission between the master earphone and the terminal equipment are the same, and if the antennas are the same, the master earphone sends a response signal based on a first target antenna of the master earphone.

For example, a first vertical polarization antenna is used when the master earphone and the terminal device perform first radio frequency signal transmission, and a first vertical polarization antenna is used when the master earphone and the slave earphone perform second radio frequency signal transmission, and at this time, the master earphone sends a response signal to the terminal device based on the first vertical polarization antenna. The first horizontally polarized antenna is similar to the first vertically polarized antenna, and is not described herein again.

And if the antenna adopted when the main earphone and the terminal equipment perform signal transmission is different from the antenna adopted when the main earphone and the auxiliary earphone perform signal transmission, the main earphone sends a response signal to the terminal equipment through the antenna adopted when the main earphone and the auxiliary earphone perform signal transmission. That is, if it is detected that the antenna used for signal transmission between the master earphone and the slave earphone is different from the antenna used for signal transmission between the master earphone and the terminal device, the current antenna of the master earphone is switched to the antenna used for signal transmission between the master earphone and the terminal device, and a response signal is sent to the terminal device based on the switched antenna.

For example, a first vertical polarization antenna is used when the master earphone and the terminal device perform first radio frequency signal transmission, and a first horizontal polarization antenna is used when the master earphone and the slave earphone perform second radio frequency signal transmission, at this time, the master earphone switches the first horizontal polarization antenna to the first vertical polarization antenna, and sends a response signal to the terminal device based on the first vertical polarization antenna. It can also be understood that, when the antenna used when the master earphone and the terminal device perform the first radio frequency signal transmission is different from the antenna used when the master earphone and the slave earphone perform the second radio frequency signal transmission, the antenna used when the master earphone and the terminal device perform the first radio frequency signal transmission is selected to send the response signal to the terminal device.

Optionally, in some possible implementations of the present application, during a transmission process of a bluetooth packet, in a first communication timeslot, the master earphone communicates with the terminal device based on the master ear first target antenna, and/or the slave earphone communicates with the terminal device based on the slave ear first target antenna; communicating, by the master earpiece with the slave earpiece based on the master ear second target antenna or communicating, by the slave earpiece with the master earpiece based on the slave ear second target antenna at a second communication time slot; and the main earphone sends the response signal to the terminal equipment based on the main ear first target antenna in a third communication time slot.

The first communication time slot, the second communication time slot and the third communication time slot respectively correspond to the sending sequence and the sending time of the first radio frequency signal, the second radio frequency signal and the response signal in the transmission process of a complete Bluetooth data packet. The first communication time slot is earlier than the second communication time slot, and the second communication time slot is earlier than the third communication time slot. The second radio frequency signal of the second communication time slot may include a synchronization signal and/or a retransmission signal.

Illustratively, the user is shown wearing only two TWS headphones. When a user wears two earphones in the TWS earphone at the same time, the earphone which is directly connected with the mobile phone through Bluetooth is a main earphone, virtual Bluetooth connection is established between the earphone and the main earphone, and the earphone which is indirectly connected with the mobile phone is a slave earphone. The mobile phone converts an audio signal to be sent into a first radio frequency signal and then broadcasts the first radio frequency signal, the main earphone detects the first radio frequency signal in a first communication time slot, and simultaneously, the information of the first radio frequency signal is broadcasted to the auxiliary earphone, so that the auxiliary earphone can monitor the first radio frequency signal broadcasted by the mobile phone. After a primary earphone detects a first radio frequency signal broadcasted by a mobile phone in a first communication time slot, a received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header is obtained based on a first horizontal polarization antenna in the primary earphone, and a received signal strength indication corresponding to a first test signal of the first radio frequency signal packet header is obtained based on a first vertical polarization antenna in the primary earphone. After the slave earphone monitors the first radio frequency signal sent by the terminal device in the second communication time slot, a received signal strength indication corresponding to a first test signal in a first radio frequency signal packet header is obtained based on a second horizontal polarization antenna in the slave earphone, and a received signal strength indication corresponding to a first test signal in the first radio frequency signal packet header is obtained based on a second vertical polarization antenna in the slave earphone. And the master earphone and the slave earphone respectively determine the target antenna corresponding to the master earphone and the slave earphone according to the acquired received signal strength indication. For example, a user puts a mobile phone in a pocket, at this time, the master earphone and the slave earphone are both in a vertical state with the mobile phone, at this time, the vertical polarization antennas of the master earphone and the slave earphone have excellent performance on radio frequency signal transmission, the master earphone compares received signal strength indications corresponding to the two antennas, so that the party with the excellent received signal strength indication is the first vertical polarization antenna, the first vertical polarization antenna is used as a first target antenna of the master ear, and the first radio frequency signal sent by the mobile phone is received based on the first vertical polarization antenna; the same process is done for the slave earpiece.

If the user wears one earphone (such as a master earphone) and the other slave earphone and the mobile phone are both placed on a desk, the master earphone compares the received signal strength indications corresponding to the two antennas at the moment, so that the party with the better received signal strength indication is the first vertical polarization antenna, and receives a first radio frequency signal sent by the mobile phone based on the first vertical polarization antenna. And the slave earphone and the mobile phone are in a horizontal state, at the moment, the slave earphone compares the received signal strength indications corresponding to the two antennas, so that the better one of the received signal strength indications is the second horizontally polarized antenna, and the signal transmitted by the mobile phone is received based on the second horizontally polarized antenna.

After both the master and slave earpieces receive the rf signal, the master earpiece may transmit a second rf signal (e.g., a synchronization signal) to the slave earpiece. And detecting a synchronous signal sent by the main earphone from the earphone in the second communication time slot, acquiring a received signal strength indication corresponding to the synchronous signal, and determining an antenna for transmitting the synchronous signal based on the received signal strength indication. For example, when the user wears both the master earphone and the slave earphone on the ears, the master earphone and the slave earphone are in a parallel state, and the slave earphone and the master earphone compare the corresponding received signal strength indications, it can be obtained that the antenna with the better received signal strength indication is the horizontally polarized antenna. The master earphone and the slave earphone transmit synchronous signals based on the horizontal polarization antenna. Or, the user wears one earphone (such as the master earphone) and the other slave earphone is placed on the table, the master earphone and the slave earphone are in a vertical state at the moment, and the slave earphone and the master earphone can obtain the vertical polarization antenna which is the better one of the received signal strength indications by comparing the received signal strength indications corresponding to the master earphone and the slave earphone. The master earphone and the slave earphone transmit synchronous signals based on a vertical polarization antenna.

And after the synchronous signal transmission between the master earphone and the slave earphone is finished, the master earphone sends a response signal to the mobile phone in the third communication time slot. If the master earphone starts to receive the radio frequency signal broadcasted by the mobile phone based on the first vertical polarization antenna in the round of radio frequency signal transmission, and the transmission of the synchronous signal is carried out on the way with the slave earphone through the first vertical polarization antenna, the response signal is directly sent to the mobile phone based on the currently used antenna, namely the first vertical polarization antenna. In this round of radio frequency signal transmission, when the master earphone starts to receive a radio frequency signal broadcasted by the mobile phone based on the first vertical polarization antenna and the transmission of a synchronization signal is performed with the slave earphone through the first horizontal polarization antenna midway, the antenna is switched to the first vertical polarization antenna at this time, and a response signal is transmitted to the mobile phone through the first vertical polarization antenna. And the mobile phone receives the response signal sent by the main earphone and carries out a new radio frequency signal transmission.

In the embodiment of the present application, signal transmission is performed between the master earphone and the terminal device, and between the master earphone and the slave earphone, on the other hand, it is understood that in a possible implementation manner, when the master earphone detects that an object to which the master earphone performs signal transmission changes, an antenna selected by the master earphone to transmit a signal also changes correspondingly. And then, the proper antenna is selected to transmit signals, so that the signal transmission between the main earphone and the terminal equipment and between the main earphone and the auxiliary earphone reach the optimal state, and the phenomena of voice blockage, delay and the like of the Bluetooth earphone are avoided.

Optionally, in some possible implementations of the present application, when the user wears only one TWS headset, only the first communication timeslot and the third communication timeslot are present. Illustratively, when the user uses only one headset, the headset establishes a bluetooth connection with the terminal device, which is also the master headset. The terminal equipment converts an audio signal to be sent into a first radio frequency signal and then broadcasts the first radio frequency signal, the main earphone detects the first radio frequency signal in a first communication time slot, a received signal strength indication corresponding to a first test signal of a first radio frequency signal packet header is obtained based on a first horizontal polarization antenna in the main earphone, and a received signal strength indication corresponding to a first test signal of the first radio frequency signal packet header is obtained based on a first vertical polarization antenna in the main earphone. The main earphone compares the two received signal strength indications, and selects an antenna corresponding to the side with the better received signal strength indication as a first target antenna of the main earphone. For example, after a user wears a main earphone, the terminal device (e.g., a mobile phone) is put in a pocket, the main earphone and the mobile phone are in a vertical state, at this time, a first vertical polarization antenna has a better performance for transmitting a first radio frequency signal, the main earphone can obtain that the party with the better received signal strength indication number is the first vertical polarization antenna by comparing received signal strength indications corresponding to the two antennas, the first vertical polarization antenna is used as a first target antenna of a main ear, and the first radio frequency signal sent by the mobile phone is received based on the first vertical polarization antenna. Then, the main earphone sends a response signal to the mobile phone in the third communication time slot based on the first vertical polarization antenna, and the mobile phone receives the response signal sent by the main earphone and carries out a new radio frequency signal transmission.

Optionally, in some possible implementations of the present application, in a preset time period, the master earphone communicates with the terminal device based on a first target antenna of the master ear used in transmission of a first bluetooth data packet in the preset time period, and communicates with the slave earphone based on a second target antenna of the master ear used in transmission of the first bluetooth data packet in the preset time period;

the slave earphone is communicated with the terminal device based on a first target antenna of a slave ear adopted during transmission of a first Bluetooth data packet in the preset time period, and is communicated with the master earphone based on a second target antenna of the slave ear adopted during transmission of the first Bluetooth data packet in the preset time period.

The preset time period may be set and adjusted according to actual situations, for example, the preset time period may be a time required for transmitting one bluetooth data packet, which is only an exemplary illustration and is not limited thereto. The communication object of the master earphone refers to the terminal equipment or the slave earphone, and the communication object of the slave earphone refers to the terminal equipment or the master earphone.

For example, in a preset time period, the first target antenna of the main ear used by the main earphone during the first bluetooth packet transmission in the preset time period is a first horizontally polarized antenna, and then the communication with the terminal device is always performed through the first horizontally polarized antenna in the preset time period. In a preset time period, a first target antenna of the main earphone adopted during transmission of a first bluetooth data packet in the preset time period is a first vertical polarization antenna, and the main earphone is communicated with the terminal equipment through the first vertical polarization antenna in the preset time period. And in a preset time period, the second target antenna of the master earphone adopted when the first Bluetooth data packet is transmitted in the preset time period is the first horizontal polarization antenna, and the master earphone is communicated with the slave earphone through the first horizontal polarization antenna in the preset time period. In a preset time period, a second target antenna of the master earphone adopted when the master earphone transmits a first Bluetooth data packet in the preset time period is a first vertical polarization antenna, and the master earphone always communicates with the slave earphone through the first vertical polarization antenna in the preset time period.

For example, in a preset time period, the first target antenna of the slave ear used by the slave earphone during the transmission of the first bluetooth data packet in the preset time period is the second horizontally polarized antenna, and then the communication with the terminal device is always performed through the second horizontally polarized antenna in the preset time period. And in a preset time period, a first target antenna of the slave ear adopted by the slave earphone during the transmission of the first Bluetooth data packet in the preset time period is a second vertical polarization antenna, and the slave earphone is communicated with the terminal equipment through the second vertical polarization antenna in the preset time period. And in a preset time period, a second target antenna of the slave ear adopted by the slave earphone during the transmission of the first Bluetooth data packet in the preset time period is a second horizontally polarized antenna, and the slave earphone is communicated with the master earphone through the second horizontally polarized antenna in the preset time period. And in a preset time period, a second target antenna of the slave ear adopted by the slave earphone during the transmission of the first Bluetooth data packet in the preset time period is a second vertical polarization antenna, and the slave earphone is communicated with the master earphone through the second vertical polarization antenna in the preset time period.

Optionally, in some possible implementations of the present application, in a preset time period, the master earphone detects whether a communication object of the master earphone is changed, that is, the master earphone detects whether the terminal device communicating with the master earphone is switched to the slave earphone or whether the slave earphone communicating with the master earphone is switched to the terminal device. When the communication object of the master earphone is not changed, that is, the communication object is always a terminal device or is always a slave earphone in the preset time period, the master earphone performs signal transmission based on the antenna used for the first communication in the preset time period, that is, the master earphone performs signal transmission based on the antenna used for the first signal transmission with the communication object in the preset time period.

For example, the slave earphone detects whether the communication object of the slave earphone is changed within a preset time period, that is, the slave earphone detects whether the terminal device communicating with the slave earphone is switched to the master earphone or whether the master earphone communicating with the slave earphone is switched to the terminal device. When the communication object of the slave earphone is not changed, that is, the communication object with the slave earphone is always the terminal device or the master earphone in the preset time period, the slave earphone performs signal transmission based on the antenna adopted during the first communication in the preset time period, that is, the slave earphone performs signal transmission based on the antenna adopted during the first signal transmission with the communication object in the preset time period.

The signal processing method can also enable the Bluetooth headset to keep a good signal transmission state all the time, and further enhances the anti-interference capability of the Bluetooth headset in a complex interference environment.
