detailed description

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In this embodiment, in order to enable a user to implement a far-field interaction function with a terminal when using a wireless headset, a headset far-field interaction accessory is used as a result output device under the far-field interaction function to implement the far-field interaction between the wireless headset and the terminal Features. The main body of this embodiment is the headset far-field interaction accessory. For details, please refer to FIG. 1. FIG. 1 is a flowchart of a headset far-field interaction method according to an embodiment of the present invention. The method is applied to a headset far-field interaction accessory, and may specifically include:

S100. When the headset far-field interaction accessory detects a preset event that triggers the far-field interaction function, it receives response information sent by the first wireless headset connected to the terminal. The response information is that the first wireless headset will be picked up by the microphone in the wireless headset. The voice instruction information is sent to the terminal, and the response information obtained by the terminal processing the voice instruction information is received.

S110. Output response information.

This embodiment does not limit the preset event, and the user can set it according to the actual situation. For example, it is detected that a wireless headset is placed in the headset far-field interaction accessory, or it is detected that a wireless headset is connected to the headset far-field interaction accessory. Further, this embodiment does not limit the detection method of the preset event, and the user can make corresponding settings according to the set preset event. For example, when the preset event is detected that a wireless headset is placed in the headset far-field interaction accessory, the detection method of the corresponding preset event may be detecting whether the value of the pressure sensor at each position where the wireless headset is placed in the headset far-field interaction accessory is Detect a preset event for a preset value, or detect that a touch switch on each position where a wireless headset is placed in the headset far-field interaction accessory is pressed to detect the preset event. When the preset event detects that a wireless headset is connected to the headset far-field interaction accessory, the detection method of the corresponding preset event may be to detect whether the corresponding interface (such as a USB interface or a UART interface) is connected to detect the preset. event.

To improve the reliability of triggering the far-field interaction function, preferably, this embodiment detects a preset event by determining that a wireless headset is placed in the headset far-field interaction accessory. It is simply understood that as long as there is a wireless headset in the headset far-field interaction accessory, it means that the wireless headset is not in the near-field interaction state with the terminal at this time, and it can be used to implement the far-field interaction function with the terminal. Further, in order to improve the reliability of the preset event detection. Preferably, in this embodiment, it is determined that a wireless headset is placed in the headset far-field interaction accessory by touching the touch switch in a pressed state. That is, it is detected whether there is a wireless headset at the position where the wireless headset is currently placed by using the pressed state of the touch switch. This embodiment does not limit the type of the tact switch, and may be, for example, a spring-type tact switch.

When the headset far-field interaction accessory detects a preset event that triggers the far-field interaction function, the far-field interaction function can be turned on. At this time, it is connected to the headset far-field interaction accessory or is placed in the wireless headset in the headset far-field interaction accessory. The microphone is in a working state ready to pick up voice command information. The microphone in the corresponding wireless headset may be turned on when the far-field interaction function is turned on, or may be always on, but only when the far-field interaction function is turned on can pick up voice instruction information. In order to save the power of the wireless headset, the microphone in the wireless headset is preferably turned on only when the far-field interaction function is turned on, or the microphone is turned on only when the wireless headset needs to use the microphone.

Further, the type and number of microphones in the wireless headset are not limited in this embodiment. For example, the microphones may be a single microphone or a multi-microphone array composed of multiple microphones. Users can set it according to the actual pickup requirements and cost requirements. In order to improve the adaptability of the microphone in the wireless headset to the environment and the quality of the picked-up voice instruction information, it is preferable that the microphone in the wireless headset in this embodiment may use a multi-microphone array.

This embodiment does not limit the setting position of the microphone in the wireless headset. For example, it can be provided on the outer surface of a wireless headset. The user can choose the setting position according to the specific microphone type and pickup characteristics actually selected. When the microphones form a Dome array, this embodiment does not limit the number of microphones in the Dome array, the distance between the microphones, and the positions where the microphones are set. In order to have a good effect of far-field pickup, it is preferable that the microphones in the Dome array must be on the same plane, and the distance between the two microphones is between 20 and 40 mm, and the microphones must be well sealed. The number of microphones in the corresponding Dome array can be two to four to achieve far-field pickup. Since the size of the wireless headset is relatively small, it is sufficient to set two microphones in a preferred wireless headset. For details, please refer to FIG. 2, and a schematic diagram of a method of setting up a multi-microphone array is shown by taking two microphones as an example. Each wireless headset has two microphones for the near field, and a total of 4 microphones will be combined and used as the far field pickup.

It can be understood that this embodiment does not limit the content of specific voice instruction information, such as address query, flight information, traffic conditions, navigation prompts, short sentence translations, and prompt information. When the terminal is a mobile phone, it can also include a call Messages, text messages, email messages, etc. Of course, this embodiment does not limit the specific format of the voice instruction information. For a specific microphone pickup process, reference may be made to a specific process of an existing microphone pickup. This embodiment does not limit the execution subject of the specific far-field pickup algorithm processing. Preferably, considering the volume of the wireless headset, it can be executed by the terminal. Correspondingly, the wireless headset only needs to simply pick up the voice command information.

This embodiment is to implement the far-field interaction function of the wireless headset, so the collected voice instruction information needs to be sent to the corresponding terminal, and then the terminal's response information to the voice instruction information is received. At this time, the first wireless headset needs to use the first wireless headset to send the voice instruction information picked up by the microphone in the wireless headset to the terminal and receive the response information obtained by the terminal processing the voice instruction information to realize data interaction between the wireless headset and the corresponding terminal. Finally, the first wireless headset sends the received response information to the headset far-field interaction accessory, so that the headset far-field interaction accessory outputs the response information, thereby realizing the far-field interaction function.

In this embodiment, the number of wireless headphones that collect voice instruction information is not limited. For example, it can be collected and sent by the first wireless headset; it can also be collected by the second wireless headset and sent by the first wireless headset; of course, it can also be collected by two wireless headsets together, but the two wireless headsets are aggregated by the first wireless headset Pick up the voice command message and send it. In order to ensure the collection effect of the voice instruction information, preferably, this embodiment uses two wireless headphones to collect the voice instruction information together. For example, when multiple wireless headsets collectively collect, the process may be: each wireless headset performing the far-field interaction function uses a microphone to pick up voice instruction information, the first wireless headset receives the voice instruction information sent by a non-first wireless headset, and It is combined with the voice instruction information picked up by itself to form the final voice instruction information; the first wireless headset sends the final voice instruction information to the terminal, and the terminal responds to the received voice instruction information to obtain response information, and the response information Send to the first wireless headset, and finally the first wireless headset sends the received response information to the headset far-field interaction accessory, and the headset far-field interaction accessory finally outputs the response information to the user.

In this embodiment, the first wireless headset is a wireless headset that is connected to the terminal and can communicate with the terminal to implement data exchange. That is, when the wireless earphone is a single-ear wireless earphone, the wireless earphone is the first wireless earphone. When the wireless earphone is a binaural wireless earphone, the first wireless earphone may be determined according to a situation. For example, if only two master wireless headsets can be connected to the terminal, only when the master wireless headset is placed in the headset far-field interaction accessory (whether the slave wireless headset is placed in the headset far-field interaction accessory does not affect) Use the main wireless headset as the first wireless headset. If both wireless headsets can be connected to the terminal, if only one wireless headset is placed in the headset far-field interaction accessory at this time, the wireless headset can be used as the first wireless headset. At this time, if both wireless earphones are placed in the earphone far-field interaction accessory, the first wireless earphone can be selected according to a preset selection condition. This embodiment does not limit the preset selection conditions. For example, the first wireless headset may be selected according to the current power of the two wireless headsets; or the wireless headset connected to the terminal before being placed in the headset far-field interaction accessory may be used as the first wireless headset.

Since the first wireless headset consumes power when performing data interaction with the terminal and the headset far-field interaction accessory, in order to avoid the situation where the far-field interaction function is interrupted due to lack of power during use of the first wireless headset, it is preferable, When there are two wireless headphones, the determining manner of the first wireless headphones in this embodiment may include:

Detect the battery power of two wireless headsets in the headset far-field interaction accessory;

Specifically, in the preferred embodiment, a suitable wireless earphone is selected as the first wireless earphone according to the battery power of the wireless earphone. This embodiment does not limit the detection method of the battery power of the two wireless headsets, as long as the headset far-field interaction accessory can obtain the battery power data of the two wireless headsets (of course, the determination process of the first wireless headset can also be performed by wireless The headset is completed, that is, the current master wireless headset obtains the battery power of itself and the slave wireless headset, and the wireless headset with the higher battery capacity is selected as the first wireless headset. The specific process can be when the battery power of the primary wireless headset is high, which is directly the first A wireless headset; when the battery power of the secondary wireless headset is high, the master-slave switch is performed first, and the primary wireless headset is used as the first wireless headset after the switch; or the secondary wireless headset is directly used as the first wireless headset).

For example, the headset far-field interaction accessory may send battery power acquisition information to the wireless headset, the current master wireless headset obtains the battery power from the wireless headset and itself, and sends the battery power of the two wireless headsets to the headset far-field interaction accessory. Of course, it may also be that the headset far-field interaction accessory sends the battery power acquisition information to each wireless headset separately, and then receives the corresponding battery power from each wireless headset. This embodiment does not limit the process of establishing a connection between the first wireless terminal and the terminal. For example, the first wireless headset may be switched to the primary wireless headset, and then the connection between the primary wireless headset and the terminal is established. The switching process and the process of connecting the main wireless headset to the terminal can refer to the processes in the prior art. At this point, another wireless headset with a low battery level can be put to sleep to save power.

This embodiment is not limited to the foregoing determining the execution frequency of the first wireless headset according to the battery power. For example, when the battery level of the first wireless headset decreases to a threshold during use, the execution is triggered. Of course, the above-mentioned process of determining the first wireless headset according to the battery level may continue during the working process of the headset far-field interaction accessory, so as to ensure that the first wireless headset that performs data interaction with the headset far-field interaction accessory is the battery level. Higher wireless headphones.

Further, this embodiment does not limit the type of the terminal. For example, it can be a mobile phone, a tablet, or a PC. As long as the terminal has a wireless connection module for wireless communication with the wireless headset (this embodiment does not limit the wireless connection module, such as a Bluetooth module, or a WIFI module, or a BLE module), and can process voice command information The processor that gets the response information is sufficient. That is, this embodiment does not limit the specific manner of wireless transmission between the wireless headset and the terminal. Of course, the terminal can also process the voice command information by connecting to the cloud through a wireless connection module to obtain response information, as long as the terminal can receive the response information.

Specifically, in this embodiment, the manner in which the headset far-field interaction accessory performs data interaction with the first wireless headset is not limited. For example, data can be exchanged through a USB interface or a UART interface. That is, optionally, the voice instruction information is sent to the first wireless headset connected to the terminal through a USB interface or a UART interface. The selection of a specific communication interface can be set according to the settings of the external interface of the specific wireless headset and the corresponding communication protocol. Generally, the interface corresponding to the current widely applicable communication protocol is selected in order to improve the adaptability of wireless headsets and headset far-field interaction accessories. For example, if you currently want to implement far-field calls through the far-field interaction function, that is, the user implements the process of receiving / calling at a distance from the terminal, then you need to receive the first connection to the terminal through the UART interface (such as the 5pins interface). A response message sent by the wireless headset. Because the current use of the UART interface can meet the protocol corresponding to real-time calls, the need for invalidity.

Before the voice instruction information picked up by the microphone in the wireless headset in this embodiment, it is necessary to set the corresponding parameter of the wireless headset that collects the voice instruction information as a parameter under the far-field interaction function. This embodiment does not limit the types of selected parameters to be set and the specific values of the corresponding settings. For example, the input audio path, output audio path, and corresponding noise reduction parameters of the wireless headset can be set. For example, the near-field noise reduction processing of the wireless headset is set to off. And because the wireless headset is small, algorithms (such as far-field noise reduction algorithms) to improve the quality of the collected voice instruction information can be performed in the terminal, and the wireless headset is only responsible for collecting voice information.

This embodiment does not limit the output form of the response information, for example, it may be a voice output, for example, output the response information through a speaker; of course, it may also output through a display screen. Further, this embodiment does not limit the position where the output device with the output function is set. For example, when the output device is a speaker, it can be set on the outside of the headset far-field interaction accessory.

This embodiment also does not limit the number of output devices that implement the output function. For example, two speakers can be set for voice output, and the response information can be output through two speakers. Of course, since the number of wireless earphones can be two, one speaker can be set to correspond to one wireless earphone. The response information received at this time can be output through corresponding speakers according to actual needs. Two speakers can be placed on the outer side of the headset far-field interaction accessory to provide stereo playback of wireless headphones.

This embodiment is implemented after the user does not need to take out the terminal, and uses a combination of a headset far-field interaction accessory and a wireless headset (the wireless headset may be a wireless headset when currently not needed or wants to implement a far-field interaction function). Wireless headset far-field interaction function, used to query online information, including address query, flight information, traffic conditions, navigation prompts, short sentence translation, making a call, etc .; or to receive some output information of the terminal, including music playback, text messages Tips, device control, etc.

Based on the foregoing embodiment, in order to improve the utilization ratio of the headset far-field interaction accessory and enable it to implement multiple functions, in this embodiment, the headset far-field interaction accessory may also output prompt information sent by the terminal through the first wireless headset.

Specifically, the prompt information output in this embodiment does not need to first pick up the voice instruction information through the wireless headset, and is directly the prompt information sent by the terminal through the first wireless headset. The specific content of the prompt information is not limited in this embodiment, and may be, for example, caller information, caller prompt, short message prompt, weather prompt, working status prompt of other smart devices (such as smart home devices), and the like. Of course, the output form of the prompt information is not limited in this embodiment, and may be a voice output, a screen output, or an indicator light. Further, the headset far-field interaction accessory may also output the status (working state or hibernation state) of the wireless headset itself and / or the wireless headset placed in the headset far-field interaction accessory. Of course, it can also provide input forms such as keys for users to set the headset far-field interaction accessories.

Based on the above technical solution, the earphone far-field interaction method provided by the embodiment of the present invention can realize the far-field interaction function of the wireless earphone, so that the user can have the benefits of near-field and far-field interaction when using the wireless earphone, and improve the user experience, and Output the prompt information to expand the functions of the headset far-field interaction accessory.

Since the wireless headset is convenient to use, and the headset far-field interaction accessory needs to be used with the wireless headset, the headset far-field interaction accessory needs to be able to adapt to various use environments. For example, it can be used indoors, including homes or offices; it can also be used outdoors, such as roads, vegetable fields, or parks; and users can have a variety of sports states under various use environments, corresponding to the headset far-field interaction accessories can have multiple Sports status, such as it can adapt to the user's running status such as running, driving, cycling, etc. Therefore, in various application scenarios, users also have different volume requirements for response information output through a voice such as a speaker. Therefore, in order to improve the user experience, based on any of the above embodiments, preferably, this embodiment can correspond to the current application scenario. The output mode outputs a response message.

Specifically, the user can check the playback volume of the headset far-field interaction accessory according to the current application scenario. This embodiment does not limit the specific correspondence between the application scenario and the output mode. For example, when it is determined according to the environmental state information that the current application is a quiet application, a normal application, or a noisy application, the output volume of the corresponding output mode is A, B, or C; where A is less than B and B is less than C.

This embodiment does not limit the specific determination manner of the current application scenario. For example, the current application scenario may be determined according to the current state of motion of the far-field interactive accessory of the headset, or the current application scenario may be determined according to the current environmental state information. Of course, the current state may also be determined by combining the motion state and environmental state information. Application scenarios.

Based on the above technical solution, the earphone far-field interaction method provided by the embodiment of the present invention can realize the far-field interaction function of the wireless earphone, so that the user can have the benefits of near-field and far-field interaction when using the wireless earphone, and improve the user experience, and The effect of corresponding voice output response information can be determined according to the current application scenario, thereby further improving the user experience.

Based on any of the above embodiments, in order to improve the utilization ratio of the headset far-field interaction accessory and enable it to implement multiple functions, in this embodiment, the headset far-field interaction accessory may also include a charging function. The specific headset far-field interaction accessory uses a mobile power supply. The circuit charges the device connected to the headset's far-field interaction accessory. This embodiment does not limit the specific form of the mobile power circuit and the type of connected charging device (for example, a wireless headset). The specific form of the mobile power circuit can be specifically set according to the type of equipment it can charge. That is, the headset far-field interaction accessory can be used as a mobile charging treasure, or a mobile charging device that only charges wireless headphones.

This embodiment does not limit the interface to which the device is connected to the headset far-field interaction accessory, and it is determined according to the type of the device. For example, it can be a USB interface or a UART interface. Of course, the headset far-field interaction accessory can also have an interface for charging the headset far-field interaction accessory with an external power supply to meet the normal use of the headset far-field interaction accessory and the function of charging the device. This interface is determined according to actual needs and is generally selected. Currently commonly used interfaces, such as USB interfaces.

Based on any of the above embodiments, in order to ensure the normal use of the headset far-field interaction accessory, when a user needs to use the headset far-field interaction accessory, it is necessary to first check whether the battery power of the headset far-field interaction accessory meets the usage requirements. This embodiment does not limit the frequency at which the headset far-field interaction accessory detects whether its own battery power is too low. It can be the real-time detection of its own battery power, or it can be detected according to a preset period. Of course, it can also be performed when a headset far-field interactive accessory is needed.

For example, when the headset far-field interaction accessory detects a preset event that triggers the far-field interaction function, it first needs to first check whether the battery power of the headset far-field interaction accessory can meet the working requirements (for example, whether it is lower than a set power value) , If the step of receiving the response information sent by the first wireless headset connected to the terminal is fulfilled, if not, the step of receiving the response information sent by the first wireless headset connected to the terminal is refused, and of course, it may also be prompted at this time The user's battery is low and needs to be charged. Or when it is detected that the connected device needs to perform the charging function, it can first determine whether the battery power of the headset far-field interactive accessory is lower than the working threshold; if not, the mobile power circuit is used to charge the device connected to the headset far-field interactive accessory. ; If yes, the mobile power circuit is forbidden to charge the device connected to the headset's far-field interaction accessory; of course, it can also prompt the user that the battery is low and needs to be charged.

This embodiment does not limit the specific manner of outputting the prompt information herein. For example, it can be an indicator light output, or a voice output, or you can use the terminal to output prompt information, that is, the headset far-field interactive accessory will actively send charging prompt information to the terminal through the first wireless headset when its battery power is too low to be charged .

Further, under normal circumstances, when the user does not use the headset far-field interaction accessory (such as not using its far-field interaction function or charging function), in order to lower power consumption and save energy, the headset far-field interaction accessory can be set to sleep. Mode (ie power saving mode). For example, when the wireless headset is not in the headset far-field interaction accessory and the touch switch is released, the headset far-field interaction accessory immediately enters the standby state to save power. The headset far-field interaction accessory itself can charge the internal battery through the interface. When the wireless headset is in the headset far-field interaction accessory, but the battery of the headset far-field interaction accessory is insufficient, the headset far-field interaction accessory can refuse to charge the wireless headset, and at the same time, it will send a prompt message to the terminal (such as a mobile phone) and ask the user to give The headset's far-field interactive accessory is powered.

The following describes the specific process of this embodiment with a specific example:
