detailed description

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 conjunction 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 making creative efforts fall within the protection scope of the present invention.

In this embodiment, in order to enable the user to realize the far-field interaction function with the terminal when using the wireless headset, the headset far-field interaction accessory is used as the result output device under the far-field interaction function, so as to realize the far-field interaction between the wireless headset and the terminal Features. The execution subject of this embodiment is the headset far-field interactive accessory. Please refer to FIG. 1 for details. FIG. 1 is a flowchart of a headset far-field interaction method according to an embodiment of the present invention; this method is applied to headset far-field interaction accessories, 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 the response information sent by the first wireless headset connected to the terminal; where the response information is the first wireless headset to 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 according to the actual situation. For example, it is detected that a wireless headset is placed in the headset far-field interactive accessory, or it is detected that a wireless headset is connected to the headset far-field interactive accessory. Further, this embodiment does not limit the detection method of the preset event, and the user can set accordingly according to the preset event. For example, when the preset event is the detection of the placement of a wireless headset in the headset far-field interactive accessory, the corresponding preset event detection method may be to detect whether the value of the pressure sensor at each location where the wireless headset is placed in the headset far-field interactive accessory To detect a preset event for a preset value, or to detect that the touch switches at various positions where the wireless headset is placed in the headset far-field interactive accessory are in a pressed state to detect the preset event. When the preset event is the detection that the wireless headset is connected to the headset far-field interactive accessory, the corresponding preset event detection method may be to detect whether the corresponding interface (such as a USB interface or a UART interface) is in a connected state to detect the preset event.

In order to improve the reliability of triggering the far-field interaction function, preferably, this embodiment detects a preset event by determining that there is a wireless headset 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 realize the far-field interaction function with the terminal. Further, in order to improve the reliability of preset event detection. Preferably, in this embodiment, it is determined that there is a wireless headset placed in the headset far-field interactive accessory by pressing the touch switch in a pressed state. That is, the pressing state of the touch switch is used to detect whether there is a wireless headset at the position where the wireless headset is currently placed. This embodiment does not limit the type of the tact switch, for example, it may be a spring type tact switch.

When the headset far-field interactive accessory detects a preset event that triggers the far-field interactive function, the far-field interactive function can be turned on. At this time, it is connected to the headset far-field interactive accessory or placed in the wireless headset in the headset far-field interactive accessory. The microphone is in a working state ready to pick up voice command information at any time. The microphone in the corresponding wireless headset may be turned on when the far-field interactive function is turned on, or may be always on, but only when the far-field interactive function is turned on can voice command information be picked up. In order to save the power of the wireless headset, it is preferable to turn on the microphone in the wireless headset only when the far-field interactive function is turned on, or 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, it may be a single microphone or a multi-microphone array composed of multiple microphones. Users can set according to the actual sound 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 command information, preferably, the microphone in the wireless headset in this embodiment may use a multi-microphone array.

This embodiment does not limit the installation position of the microphone in the wireless headset. For example, it can be provided on the outer surface of the wireless headset. The user can choose the setting position according to the specific type of microphone actually selected and the characteristics of the sound pickup. When the microphones form a multi-microphone array, this embodiment does not limit the number of microphones in the multi-microphone array and the spacing between the microphones, as well as the location of each microphone. In order to achieve a good far-field sound pickup effect, it is preferable that each microphone in the Domai array should be on the same plane, and the distance between each pair should be 20-40 mm, and the microphone must be kept well sealed. The number of microphones in the corresponding multi-microphone array can be 2 to 4 to achieve far-field sound pickup. Since the volume of the wireless headset is relatively small, it is sufficient to set two microphones in the preferred wireless headset. Specifically, referring to FIG. 2, a schematic diagram of a setting mode of a multi-microphone array is given by taking two microphones as examples. Each wireless headset has two talk microphones for near field, and a total of 4 microphones will be combined to be used as far field pickup.

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

This embodiment is to realize the far-field interaction function of the wireless headset, so the collected voice command information needs to be sent to the corresponding terminal, and then the terminal's response information to the voice command information is received. At this time, it is necessary to use the first wireless headset to send the voice command information picked up by the microphone in the wireless headset to the terminal and receive the response information obtained by processing the voice command information by the terminal, so as 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 interactive accessory, so that the headset far-field interactive accessory outputs the response information, thereby implementing the far-field interactive function.

In this embodiment, the number of wireless earphones that collect voice command 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, but the two wireless headsets are collected by the first wireless headset Pick up the voice command message and send it. In order to ensure the effect of collecting voice command information, preferably, this embodiment uses two wireless headphones to collect voice command information together. For example, when collectively collected by multiple wireless headsets, the process may be: each wireless headset performing a far-field interaction function uses a microphone to pick up voice command information, the first wireless headset receives voice command information not sent by the first wireless headset, and It is combined with the voice command information picked up by itself to form the final voice command information; the first wireless headset sends the final voice command information to the terminal, and the terminal responds to the received voice command information to obtain the response information, and the response information It is sent to the first wireless headset, and finally the first wireless headset sends the received response information to the headset far-field interactive accessory, and the headset far-field interactive 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, it can be understood that when the wireless earphone is a mono-ear wireless earphone, then 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 circumstances. For example, if only two primary wireless headsets can be connected to the terminal, then only when the primary wireless headset is placed in the headset far-field interactive accessory (does not affect whether the secondary wireless headset is placed in the headset far-field interactive accessory)? Use the primary 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 interactive accessory at this time, the wireless headset can be used as the first wireless headset. At this time, if both wireless headsets are placed in the headset far-field interactive accessory, the first wireless headset may 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 interactive accessory may be used as the first wireless headset.

Since the first wireless headset needs to consume 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 the lack of electricity during the use of the first wireless headset, it is preferred, When there are two wireless headphones, the determination method of the first wireless headphones in this embodiment may include:

Detect the battery power of the two wireless headphones in the headset's far-field interactive accessories;

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

For example, the headset far-field interactive accessory can send battery power acquisition information to the wireless headset, the current master wireless headset can acquire the slave wireless headset and its own battery power, and send the battery power of the two wireless headsets to the headset far-field interactive accessory. Of course, it is also possible that the headset far-field interactive accessory separately sends battery power acquisition information to each wireless headset, and then receives the corresponding battery power feedback from each wireless headset. This embodiment does not limit the process of establishing a connection between the first radio and the terminal. For example, it may be that the current first wireless headset is switched to the main wireless headset, and then the connection between the main 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 process in the prior art. At this time, another wireless headset with a lower battery power can be in a sleep state to save power consumption.

This embodiment does not limit the above-mentioned determination of the execution frequency of the first wireless headset according to the battery power. For example, it may be triggered when the battery power of the first wireless headset drops to a threshold during use. Of course, the above process of determining the first wireless headset according to the battery power can be continued during the work of the headset far-field interactive accessory, to ensure that the first wireless headset that performs data interaction with the headset far-field interactive accessory each has battery power Higher wireless headphones.

Further, this embodiment does not limit the type of terminal. For example, it can be a mobile phone, tablet, PC, etc. As long as the terminal has a wireless connection module for wireless communication with a 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 receives the response information is sufficient. That is to say, this embodiment does not limit the specific method of wireless transmission between the wireless headset and the terminal. Of course, the terminal may also connect to the cloud through the wireless connection module to process the voice instruction information 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 exchange can be realized through a USB interface, or a UART interface. That is, optionally, the voice command information is sent to the first wireless headset connected to the terminal through the USB interface or the UART interface. The selection of the specific communication interface can be set according to the setting of the external interface of the specific wireless headset and the corresponding communication protocol. Generally, the interface corresponding to the communication protocol with wider adaptability will be selected in order to improve the adaptability of the wireless headset and the headset far-field interactive accessories. For example, if you currently want to implement far-field calling through the far-field interactive function, that is, the user realizes the process of making / receiving calls at a place far away from the terminal, then you need to receive the first The response message sent by the wireless headset. Because the current use of the UART interface can meet the real-time call corresponding protocol and invalidity requirements.

In this embodiment, before the voice command information picked up by the microphone in the wireless headset, the corresponding parameter of the wireless headset that collects the voice command information needs to be set as a parameter under the far-field interaction function. This embodiment does not limit the type of the selected parameter to be set and the specific value corresponding to the setting. For example, you can set the input audio path, output audio path, and corresponding noise reduction parameters for wireless headphones. For example, the near field noise reduction processing of the wireless headset is set to off. Moreover, due to the small size of the wireless headset, algorithms for improving the quality of the collected voice command information (such as the far-field noise reduction algorithm, etc.) 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 voice output, for example, the response information is output through a speaker; of course, it may also be output through a display screen. Further, this embodiment does not limit the location where the output device with the output function is set. For example, when the output device is a speaker, it can be placed on the side outside the headset far-field interactive accessory.

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

In this embodiment, when the user does not need to take out the terminal, a combination of a headset far-field interaction accessory and a wireless headset (the wireless headset may be a wireless headset that does not currently need to be used or wants to implement a far-field interaction function) is implemented Wireless headset far-field interactive function, used to query online information, including address query, flight information, traffic conditions, navigation prompts, translation of short sentences, making phone calls, etc .; or to receive some output information of the terminal, including music playback, SMS Prompt, device control, etc.

Based on the above technical solution, the headset far-field interaction method provided by the embodiments of the present invention can realize the far-field interaction function of the wireless headset, so that the user can have the benefits of near-field and far-field interaction when using the wireless headset, and improve the user experience.

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

Specifically, the prompt information output in this embodiment may 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. In this embodiment, the specific content of the prompt information is not limited. For example, it may be caller information, caller prompt, SMS 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 above prompt information is not limited in this embodiment, and may be voice output, screen output, and of course, indicator light output. Further, the headset far-field interactive accessory can also output the status of itself and / or the wireless headset placed in the headset far-field interactive accessory (working state or sleep state). Of course, it is also possible to provide input forms such as buttons for the user to set the headset far-field interactive accessory.

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

Since the wireless headset is convenient to use, and the headset far-field interactive accessory needs to be used with the wireless headset, the headset far-field interactive accessory needs to be able to adapt to various use environments. For example, it can be used indoors, including home or office; it can also be used outdoors, such as roads, vegetable fields, or parks; and users can have a variety of sports in various environments, and the headset's far-field interactive accessories can have a variety of Exercise state, for example, it can be adapted to the user's exercise state such as running, driving, cycling. Therefore, in various application scenarios, users also have different volume requirements for the response information output through voices such as speakers. 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 response information.

Specifically, the user may check the playback volume of the headset far-field interactive 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 determining whether it is a quiet application scene, a normal application scene, or a noisy application scene according to the environmental state information, the output volume of the corresponding output mode is A, B, and C; where A is less than B and B is less than C.

This embodiment does not limit the specific determination method of the current application scenario. For example, the current application scenario can be determined based on the current motion state of the headset's far-field interactive accessory, or the current application scenario can be determined based on the current environmental state information, and of course, the motion state and environmental state information can be combined to determine the current Application scenarios.

Based on the above technical solution, the headset far-field interaction method provided by the embodiments of the present invention can realize the far-field interaction function of the wireless headset, so that users can have the benefits of near-field and far-field interaction when using the wireless headset, and improve the user experience, and The effect of the 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 rate of the headset far-field interactive accessory and enable it to realize multiple functions, in this embodiment, the headset far-field interactive accessory may also include a charging function, and the specific headset far-field interactive accessory uses a mobile power supply The circuit charges the device connected to the headset's far-field interactive accessory. In this embodiment, the specific form of the mobile power circuit and the type of the connected charging-required device (for example, wireless earphones) are not limited. The specific form of the mobile power circuit can be specifically set according to the type of device that can be charged. That is, the headset far-field interactive accessory can be used as a mobile charging treasure, or a mobile charging device that only charges wireless headsets.

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

Based on the above technical solution, the headset far-field interaction method provided by the embodiments of the present invention can realize the far-field interaction function of the wireless headset, so that users can have the benefits of near-field and far-field interaction when using the wireless headset, and improve the user experience, and Through the mobile power circuit to expand the mobile charging function of the headset far-field interactive accessories.

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

For example, when the headset far-field interactive accessory detects a preset event that triggers the far-field interactive function, it is first necessary to first detect whether the battery power of the headset far-field interactive accessory can meet the work requirements (for example, whether it is lower than a set power value) If it is satisfied, then perform the step of receiving the response information sent by the first wireless headset connected to the terminal, if not, then refuse to perform the step of receiving the response information sent by the first wireless headset connected to the terminal, of course, you can also prompt at this time The user's battery is low and needs to be charged. Or when it is detected that a connected device needs to perform a charging function, it can first determine whether the battery power of the headset far-field interactive accessory is below the operating threshold; if not, use the mobile power circuit to charge the device connected to the headset far-field interactive accessory ; If it is, the mobile power circuit is prohibited from charging the device connected to the far-field interactive accessory of the headset; of course, at this time, the user may also be prompted to have a low battery and need to be charged.

This embodiment does not limit the specific manner of outputting the prompt information here. For example, it can be an indicator light output, or a voice output, or it can use the terminal to output a prompt message, that is, the headset far-field interactive accessory will actively send a charging prompt message to the terminal through the first wireless headset when its own battery power is too low and needs 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 interactive accessory, the touch switch is released, and the headset far-field interactive accessory immediately enters a standby state to save power. The headset far-field interactive accessory itself can charge the internal battery through the interface. When the wireless headset is in the headset's far-field interactive accessory, but the battery of the headset's far-field interactive accessory is insufficient, the headset's far-field interactive accessory can refuse to charge the wireless headset, and at the same time prompt information is sent to the terminal (such as a mobile phone) to request the user Headphone far-field interactive accessories power supply.

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