In an embodiment, the present application provides a parameter updating method for an audio listening device, which is described by taking the method as an example applied to the audio listening device in fig. 1, as shown in fig. 2, and the parameter updating method includes the following steps:
s210, establishing low-power Bluetooth communication connection between the audio listening device and the terminal.
The Bluetooth Low Energy (BLE) is a personal area network technology designed by the Bluetooth alliance. Bluetooth low energy is intended to significantly reduce power consumption and cost while maintaining equivalent communication range relative to classical bluetooth. Specifically, the audio listening device and the terminal are both provided with a low-power-consumption Bluetooth communication module, and when the audio listening device and the terminal are both Bluetooth-enabled, a low-power-consumption Bluetooth communication connection between the audio listening device and the terminal is established. It is understood that voice data such as voice commands, audio information, etc. can be transmitted through the bluetooth low energy communication connection between the audio listening device and the terminal.
S220, acquiring Bluetooth performance parameters of the terminal through the low-power Bluetooth communication connection.
The bluetooth performance parameter refers to a performance parameter of the low power consumption bluetooth module in the terminal, for example, the bluetooth performance parameter may be a bluetooth protocol version, a maximum allowed bluetooth low energy packet size, a minimum allowed bluetooth low energy transmission interval, and the like. Specifically, the terminal is installed with a voice assistant application, by which bluetooth performance parameters of the terminal can be acquired. And transmitting the Bluetooth performance parameters of the terminal to the audio listening equipment through the low-power-consumption Bluetooth communication connection, and acquiring the Bluetooth performance parameters of the terminal by the audio listening equipment.
S230, according to the acquired Bluetooth performance parameters of the terminal, searching corresponding first voice data transmission parameters from a voice data transmission parameter list of the low-power Bluetooth.
The voice data transmission parameter refers to a parameter for transmitting voice data between the audio listening device and the terminal through the bluetooth low energy communication connection, and the voice data transmission parameter may be the size of each packet of the voice data, the transmission interval time of the voice packet, the voice compression ratio, the secondary retransmission switch parameter, and the like. The voice compression ratio refers to a ratio parameter adopted for compressing voice data collected by the audio listening device in order to improve transmission efficiency. The retransmission-twice switching parameter refers to a parameter for changing the retransmission-twice switching state. The voice data transmission parameter list is pre-stored with the relation data between the terminal bluetooth performance parameter and the first voice data transmission parameter of the audio listening device, and the voice data transmission parameter list is stored in a storage area (such as rom) of the audio listening device. It should be noted that the voice data transmission parameter list may be updated according to a terminal connected to the audio listening device in bluetooth low energy communication, and the first voice data transmission parameter may include a voice data transmission parameter pre-stored in the audio listening device when the terminal is shipped from a factory, or a voice data transmission parameter set and stored after the terminal is shipped from a factory to ensure the link quality between the audio listening device and the terminal.
Specifically, through the bluetooth low energy communication connection, the audio listening device acquires the terminal bluetooth performance parameter, and a voice data transmission parameter list is pre-stored in the audio listening device, and then a first voice data transmission parameter corresponding to the terminal bluetooth performance parameter is searched from the voice data transmission parameter list according to the acquired terminal bluetooth performance parameter. It should be noted that the memory of the audio listening device may be divided into storage areas with fixed space, and the storage areas are used for storing the voice data transmission parameter list.
And S240, updating the parameters of the firmware of the audio listening equipment according to the searched first voice data transmission parameters.
The firmware refers to software which serves as the most basic and bottom layer of the audio listening device, a program of the firmware cannot be directly read or modified by a user, and updating parameters of the firmware refers to improving parameters in the program or source codes of the firmware. Specifically, a first voice data transmission parameter corresponding to the terminal bluetooth performance parameter is searched from the voice data transmission parameter list through the terminal bluetooth performance parameter, and the firmware of the audio listening device is updated according to the searched first voice data transmission parameter.
In the embodiment, the low-power-consumption Bluetooth communication connection between the audio listening equipment and the terminal is established; acquiring Bluetooth performance parameters of the terminal through low-power-consumption Bluetooth communication connection; searching a corresponding first voice data transmission parameter from a voice data transmission parameter list of the low-power-consumption Bluetooth according to the acquired Bluetooth performance parameter; and updating parameters of the firmware of the audio listening device according to the searched first voice data transmission parameters, improving the compatibility of the audio listening device and the terminal, solving the technical problem that the real-time voice assistant earphone cannot be normally used due to the incompatibility between the real-time voice assistant earphone and the terminal, and effectively preventing data loss in the voice data transmission process.
In one embodiment, as shown in fig. 3a, the parameter updating method further includes the following steps:
s310a, when the first voice data transmission parameter corresponding to the terminal cannot be found, sending a prompt whether to update the voice data transmission parameter to the terminal;
and S320a, if a reply of needing to update the voice data transmission parameters is received, sending an update request of the voice data transmission parameters to the terminal.
The updating request is used for indicating the packet loss rate of the low-power-consumption Bluetooth communication connection tested by the terminal. The Loss Rate (Loss Tolerance or Packet Loss Rate) is the ratio of the number of lost packets in the transmitted data group during the test. Specifically, the voice data transmission parameter list pre-stores therein relationship data between a terminal bluetooth performance parameter and a first voice data transmission parameter of the audio listening device. The first voice data transmission parameter is for most models of terminals, and the voice data transmission parameter list does not contain the first voice data transmission parameters corresponding to all terminals. When the first voice data transmission parameters corresponding to part of the terminals cannot be found, the audio listening equipment sends out a prompt for judging whether the voice data transmission parameters can be updated or not so as to inquire whether the terminals can update the voice data transmission parameters or not at present. If the current terminal state can execute the update of the voice data transmission parameters, the terminal sends a prompt for updating the voice data transmission parameters to the audio listening equipment, the audio listening equipment receives a reply of the voice data transmission parameters needing to be updated, and sends an update request of the voice data transmission parameters to the terminal, so that the compatibility between the terminal and the audio listening equipment can be improved by dynamically updating the voice data transmission parameters.
Further, as shown in fig. 3b, the parameter updating method further includes the following steps:
s310b, when the first voice data transmission parameter corresponding to the terminal cannot be found, detecting whether the terminal is in an idle state;
and S320b, if the terminal is in the idle state, sending an update request of the voice data transmission parameters to the terminal.
The idle state refers to a state that the terminal returns to the desktop to be in no operation. Specifically, when the first voice data transmission parameters corresponding to part of the terminals are not found, the voice data transmission parameters can be dynamically updated, so that the terminals and the audio listening equipment are compatible with each other. Therefore, whether the terminal is in the idle state or the standby state without operation is detected, and if the terminal is in the idle state or the standby state without operation, the audio listening device sends an update request of the voice data transmission parameters to the terminal. In this embodiment, when the first voice data transmission parameter corresponding to the terminal is not found, whether the terminal is in an idle state is detected, and if the terminal is in the idle state, an update request of the voice data transmission parameter is sent to the terminal, so as to update the voice data transmission parameter of the audio listening device, thereby improving compatibility between the audio listening device and the terminal.
In one embodiment, the testing, by the terminal, a packet loss rate of the bluetooth low energy communication connection includes: setting a second voice data transmission parameter; and testing the packet loss rate of the low-power-consumption Bluetooth communication connection through the terminal under the second voice data transmission parameter.
The second voice data transmission parameter refers to a voice data transmission parameter set by the audio listening device according to the bluetooth performance parameter of the terminal. Specifically, when the first voice data transmission parameter corresponding to part of the terminals is not found, the audio listening device inquires whether the voice data transmission parameter of the terminals is allowed to be changed, and if the voice data transmission parameter of the terminals is allowed to be changed, the audio listening device sets the second voice data transmission parameter. And under the second voice data transmission parameter, the audio listening device sends voice data to the terminal, and the packet loss rate of the low-power-consumption Bluetooth communication connection between the audio listening device and the terminal is tested through the terminal.
Illustratively, first, the audio listening device transmits a start flag signal to the terminal; secondly, a section of voice analog signal is prestored in the audio listening equipment, and the compressed voice analog signal is sent to the terminal after being compressed by a voice data compression algorithm; finally, the audio listening device sends an end flag signal to the terminal. The terminal is provided with a voice assistant application program, the packet loss rate of the low-power-consumption Bluetooth communication connection can be calculated through the voice assistant application program, the calculated packet loss rate is returned to the audio listening device, and the audio listening device judges whether the low-power-consumption Bluetooth communication connection between the terminal and the audio listening device meets the requirement of voice data transmission under the current voice data transmission parameters through the packet loss rate.
In this embodiment, when the bluetooth performance parameter of the terminal cannot be obtained, the second voice data transmission parameter of the audio listening device is updated by testing the packet loss rate, so as to solve the technical problem that the audio listening device cannot operate or the voice recognition rate is too low because the factory unified setting of the audio listening device is incompatible with the current terminal.
In one embodiment, as shown in fig. 4, the parameter updating method further includes the following steps:
s410, receiving the packet loss rate of the low-power-consumption Bluetooth communication connection returned by the terminal;
s420, if the packet loss rate does not meet the preset condition, modifying a second voice data transmission parameter;
and S430, retesting the packet loss rate under the modified second voice data transmission parameter until the packet loss rate meets the preset condition.
The setting of the preset condition relates to the quality of the voice data transmission, and the setting of the preset condition can be determined according to the actual situation, and the specific numerical value of the preset condition is not limited here. Specifically, the terminal is provided with a voice assistant application program, the voice assistant application program can calculate the packet loss rate of the bluetooth low energy communication connection and return the calculated packet loss rate to the audio listening device, and the audio listening device receives the packet loss rate of the bluetooth low energy communication connection returned by the terminal and judges whether the packet loss rate meets a preset condition. And if the packet loss rate does not meet the preset condition, modifying a second voice data transmission parameter of the audio listening device. And testing the packet loss rate of the low-power-consumption Bluetooth communication connection again by combining the modified second voice data transmission parameter until the packet loss rate meets the preset condition. This indicates that the audio listening device and the terminal are compatible with each other under the second voice data transmission parameter with the packet loss rate satisfying the preset condition, and the low power consumption bluetooth communication connection between the terminal and the audio listening device satisfies the requirement of voice data transmission. It should be noted that the second voice data transmission parameter corresponding to the packet loss ratio meeting the preset condition may be stored, the second voice data transmission parameter may be stored in a voice data transmission parameter list, or a storage area (e.g., rom) of the audio listening device may be divided, and a part of the storage area is used for storing the voice data transmission parameter list, and a part of the storage area is used for storing the second voice data transmission parameter. When the audio listening device is connected with the terminal again, the second voice data transmission parameter can be directly called to update the parameters of the firmware of the audio listening device without resetting.
In this embodiment, the second voice data transmission parameter of the audio listening device is dynamically updated by cyclically testing the packet loss rate, so that the low power consumption bluetooth connection between the audio listening device and the terminal can be normally used, and the technical problem that the audio listening device cannot operate or the voice recognition rate is too low due to the incompatibility of factory unified settings of the audio listening device and the current terminal is solved.
In one embodiment, the second voice data transmission parameter comprises a voice compression ratio. As shown in fig. 5, setting the second voice data transmission parameter includes:
and S510, setting a voice compression ratio.
The voice compression ratio is a ratio of voice data compression allowed by the terminal. Specifically, the audio listening device asks the terminal whether the voice compression ratio is allowed to be changed, and if the terminal allows the voice compression ratio to be changed and returns an indication of changing the voice compression ratio to the audio listening setting, the audio listening setting sets a new voice compression ratio.
Preferably, if the allowed voice compression ratio of the terminal is variable, in order to ensure the transmission quality of the voice data, the most fidelity voice compression ratio, i.e. the lowest voice compression ratio, of the audio listening device is preferentially set.
The second voice data transmission parameter comprises the size of each voice data packet and the voice packet sending interval time. Referring to fig. 5, the method for testing the packet loss rate of the bluetooth low energy communication connection through the terminal under the second voice data transmission parameter includes the following steps:
and S520, calculating the size of the compressed voice data stream according to the voice compression ratio.
Specifically, first, the audio listening device collects voice data to form a voice data stream in combination with an audio sampling rate, and then the audio listening device obtains a voice compression ratio of the terminal, compresses the collected voice data stream according to the voice compression ratio, and calculates a size of the compressed voice data stream. Preferably, if the lowest voice compression ratio of the audio listening device is adopted, the size of the compressed voice data stream is calculated according to the lowest voice compression ratio.
S530, calculating the size of each voice data packet and the voice packet sending interval time according to the size of the compressed voice data stream.
Wherein, the ratio of the size of each voice data packet to the voice packet transmission interval time is equal to the size of the voice data stream. Specifically, the audio listening device compresses the collected voice data stream according to the voice compression ratio allowed by the terminal, and calculates the size of the compressed voice data stream, so as to calculate the size of each packet of voice data and the voice packet transmission interval time according to the size of the compressed voice data stream.
And S540, testing the packet loss rate of the low-power-consumption Bluetooth communication connection through the terminal under the size of each voice data packet and the voice packet sending interval time.
Specifically, the size of each packet of voice data and the voice packet transmission interval time are determined according to the size of the compressed voice data stream, the audio listening device transmits the voice data to the terminal under the determined parameters of the size of each packet of voice data and the voice packet transmission interval time, and the ratio of the number of lost data packets to the transmitted data group, namely the packet loss rate of the low-power Bluetooth communication connection between the audio listening device and the terminal, is tested through a voice assistant program of the terminal.
If the packet loss rate does not meet the preset condition, modifying the second voice data transmission parameter, including:
and S550, if the packet loss rate does not meet the preset condition, reducing the size of each packet of the voice data and the transmission interval time of the voice packet.
Specifically, when the packet loss rate does not meet the preset condition, the voice compression ratio is selected to be kept unchanged, and since the size of the voice data stream is equal to the ratio of the size of each voice data packet to the transmission interval time of the voice packet, the size of the voice data stream is ensured to be unchanged by reducing the size of each voice data packet and the transmission interval time of the voice packet, so that the transmission quality of the voice data is ensured to be unchanged.
In this embodiment, if the packet loss rate does not satisfy the preset condition, the size of each packet of voice data and the transmission interval time of the voice packet are reduced by keeping the voice compression ratio unchanged, and the compatibility between the audio listening device and the terminal is improved.
In one embodiment, as shown in fig. 6, the parameter updating method further includes the following steps:
s610, acquiring the modification times of the second voice data transmission parameters;
s620, when the modification times of the second voice data transmission parameters are larger than a preset threshold value and the packet loss rate still does not meet a preset condition, sending a prompt whether the voice data transmission quality is reduced or not;
s630, if a reply that the transmission quality of the voice data needs to be reduced is received, improving the voice compression ratio;
s640, setting a corresponding third voice data transmission parameter according to the improved voice compression ratio;
and S650, retesting the packet loss rate of the low-power Bluetooth communication connection through the terminal under the third voice data transmission parameter.
Wherein the transmission quality of the voice data is determined by the voice compression ratio.

In one embodiment, as shown in fig. 7a, before searching the corresponding first voice data transmission parameter from the voice data transmission parameter list of bluetooth low energy according to the obtained bluetooth performance parameter, the method further includes:
s710, detecting the connection signal intensity of the audio listening equipment;
according to the acquired Bluetooth performance parameters, searching corresponding first voice data transmission parameters from a voice data transmission parameter list of the low-power Bluetooth, wherein the method comprises the following steps:
s720, if the connection signal strength is not lower than the preset threshold, according to the acquired Bluetooth performance parameters, searching corresponding first voice data transmission parameters from a voice data transmission parameter list of the low-power Bluetooth, and not starting a secondary retransmission mechanism.
The Received Signal Strength (RSSI) refers to the power of a bluetooth low energy Signal transmitted by a terminal and Received by an audio listening device, and the distance between the terminal and the audio listening device affects the Received Signal power. The secondary retransmission mechanism is to retransmit the voice data packet twice every time a voice data packet is transmitted and if the voice data packet is not acknowledged.
Specifically, the connection signal strength of the audio listening device is detected, the detected connection signal strength is compared with a preset threshold, and if the connection signal strength is not lower than the preset threshold, it indicates that the link quality of the current bluetooth low energy communication connection meets the requirement of voice data transmission. Then, the audio listening device searches the corresponding first voice data transmission parameter from the voice data transmission parameter list according to the acquired bluetooth performance parameter, and does not need to start a secondary retransmission mechanism.
As shown in fig. 7b, after searching the corresponding first voice data transmission parameter from the voice data transmission parameter list of bluetooth low energy according to the obtained bluetooth performance parameter, the method further includes:
s730, if the connection signal strength is lower than a preset threshold value, judging whether a secondary retransmission mechanism is started or not according to the Bluetooth performance parameters of the terminal and the size of the voice data stream of the audio listening equipment;
s740, if the secondary retransmission mechanism is started, retesting the packet loss rate of the low-power-consumption Bluetooth communication connection, and judging whether the packet loss rate after the secondary retransmission mechanism is started meets a preset condition;
and S750, if the packet loss rate still does not meet the preset condition, increasing the voice compression ratio, and re-testing the packet loss rate under the increased voice compression ratio until the packet loss rate meets the preset condition.
The bluetooth performance parameters of the terminal comprise the maximum allowed bluetooth low energy data packet size and the minimum allowed bluetooth low energy transmission interval, and the size of the voice data stream which can be accepted by the terminal can be calculated according to the maximum allowed bluetooth low energy data packet size and the minimum allowed bluetooth low energy transmission interval. Comparing the size of the voice data stream that can be received by the terminal with the size of the voice data stream under the current parameter of the audio listening device, if the size of the voice data stream that can be received by the terminal is larger than the size of the voice data stream under the current parameter of the audio listening device, it indicates that the terminal has rich performance, and a secondary retransmission mechanism may be started.
Specifically, the detected connection signal strength is compared with a preset threshold, and if the connection signal strength is lower than the preset threshold, it indicates that the link quality of the current bluetooth low energy communication connection does not meet the requirement of voice data transmission. Whether a secondary retransmission mechanism is started or not needs to be judged according to the Bluetooth performance parameters of the terminal and the size of the voice data stream of the audio listening device, if the Bluetooth performance parameters of the terminal are rich, the secondary retransmission mechanism is started, and the packet loss rate of the low-power-consumption Bluetooth communication connection is retested. And then, judging whether the packet loss rate after the secondary retransmission mechanism is started meets a preset condition or not. On one hand, if the packet loss rate after the secondary retransmission mechanism is started is improved and meets the preset condition, the starting parameter of the secondary retransmission mechanism is stored in the storage area (such as rom) of the audio listening device, and when the connection signal strength of the low power consumption bluetooth is in the condition again, the secondary retransmission mechanism can be automatically started. On the other hand, if the packet loss rate still does not meet the preset condition, the voice compression ratio is increased, and the packet loss rate is retested under the increased voice compression ratio until the packet loss rate meets the preset condition. It should be noted that, if the audio listening device is poor in use effect when the bluetooth signal is not changed by turning on the retransmission mechanism and increasing the voice compression ratio, a prompt that the audio listening device cannot be used is sent out through the terminal or the audio listening device.
In this embodiment, through opening the retransmission mechanism twice and improving the voice compression ratio, the problem that audio frequency listening equipment result of use becomes poor or can not be used when the bluetooth signal becomes poor is solved.
