A method and device for switching control of multi-mode headphones

[0001] This application claims priority to Chinese Patent Application No. 202510120497.9, filed on January 25, 2025, entitled "A Switching Control Method and Apparatus for Multimode Headphones", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to, but is not limited to, a switching control method and apparatus for multimode headphones. Background Technology

[0003] In recent years, headset design has evolved from a single-protocol device to a multi-protocol device. Traditional products typically only allow users to choose between Bluetooth, DECT, or USB: Bluetooth headsets are designed for short-range communication with mobile terminals, DECT headsets are only used with desktop base stations for medium- to long-range calls, and USB headsets rely on wired interfaces to connect to computers. With the rise of mobile work, hybrid meetings, and multi-device concurrent scenarios, users need to switch between or run different protocols simultaneously within the same headset to meet multitasking needs such as "PC-based DECT / USB conferencing + mobile phone Bluetooth calling." Therefore, the industry has begun integrating Bluetooth, DECT, and USB into a single device, creating multi-mode headsets: users can use the headset at the office to connect to a PC via a DECT base station or USB for meetings, and immediately switch to Bluetooth at home to listen to music or continue the meeting; they can also maintain a DECT / USB call on the PC while simultaneously connecting another call via Bluetooth on their mobile phone, quickly establishing a multi-party meeting. A single headset can cover all audio links for the office, home, and travel, perfectly suited to today's multitasking work and lifestyle. Invention Overview

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] For example, embodiments of this application can be applied to the field of communication technology.

[0033] Referring to Figure 1, which is a flowchart illustrating a switching control method for a multi-mode headset according to an embodiment of this application, as shown in Figure 1, this embodiment includes steps 101 to 103, and the specific steps are as follows:

[0034] The switching control method for the multimode headphones described in this application is executed by a central processing unit (CPU).

[0035] Step 101: Acquire call data from the multi-mode headset; wherein the multi-mode headset transmits call data through a communication module; the communication module includes: a first antenna, a second antenna, a Bluetooth module, and a DECT module; the first antenna is connected to the DECT module and the Bluetooth module respectively, and the second antenna is connected to the DECT module.

[0036] Step 102: Determine the call mode of the multi-mode headset based on the call data; wherein the call mode includes: DECT and Bluetooth combined call.

[0037] Step 103: When the call mode is a combined DECT and Bluetooth call, control the DECT module to disconnect from the first antenna, so that the DECT module can transmit signals through the second antenna and the Bluetooth module can transmit signals through the first antenna.

[0038] It is understood that call data from a multi-mode headset can be acquired by the headset's CPU via a Bluetooth module or a DECT module. The CPU is configured as the master control unit for both the Bluetooth and DECT modules, establishing a communication connection with them via an internal bus (such as I²C or SPI). The Bluetooth and DECT modules can report call data to the CPU via the internal bus. Furthermore, call transmission data is automatically generated by the Bluetooth or DECT module upon detecting an external communication request or audio stream, and includes protocol type, link status, and device identification information. Call mode data is generated based on the user's operation of the mode switching button, indicating the user's preset target call mode.

[0039] In this embodiment, by acquiring the call data of the multimode headset and determining the current call mode of the multimode headset based on the call data, when the call mode is confirmed to be a DECT and Bluetooth joint call, the DECT module is controlled to disconnect from the first antenna. At this time, the DECT module only transmits signals through the second antenna, and the Bluetooth module only transmits signals through the first antenna, thereby ensuring that the DECT module and the Bluetooth module do not share an antenna when operating simultaneously, thus avoiding signal interference problems that occur when multiple communication modules of the multimode headset use antennas at the same time.

[0040] Furthermore, in this embodiment of the application, when it is confirmed that the communication method of the multi-mode headset is DECT call or Bluetooth call, only one module is making a call at this time. Therefore, by reducing the transmission power of the module that is not making a call, it can be ensured that there is no signal interference between the two modules.

[0041] In one possible embodiment of this application, call data from the multi-mode headset is acquired via the CPU.

[0042] In one possible embodiment of this application, the multi-mode headset further includes: a mode switching button; the call data includes: call transmission data and call mode data;

[0043] Determining the call mode of the multi-mode headset based on the call data includes:

[0044] The call data is judged; if the call data is call transmission data, the data type of the call transmission data is extracted, and the call mode of the multi-mode headset is determined based on the data type; if the call data is call mode data, the call mode of the multi-mode headset is determined based on the call mode data; wherein, the multi-mode headset responds to the user's operation of the mode switching button and generates call mode data.

[0045] It is understandable that the call mode of the multi-mode headset is determined based on call data, including by judging through the data transmitted during the call, or by responding to the user's operation.

[0046] Understandably, the CPU identifies the acquired call data. If it is call transmission data, it means that the call has been established. The call mode is then determined based on the type of data transmitted: if the call transmission data is transmitted by the Bluetooth module, the call mode is Bluetooth call; if the call transmission data is transmitted by the DECT module, the call mode is DECT call.

[0047] If the call data is call mode data, it means that the call method is still being selected by the user (the user selects the call method by pressing the mode switch button), and the call method is determined according to the mode selected by the user. The call mode data includes: Bluetooth module enable data, DECT module enable data, and Bluetooth and DECT combined enable data. Specifically, Bluetooth module enable data corresponds to Bluetooth call, DECT module enable data corresponds to DECT call, and Bluetooth and DECT combined enable data corresponds to DECT and Bluetooth combined call.

[0048] In one possible embodiment of this application, the call mode further includes: DECT call; the switching control method further includes: when the call mode is DECT call, reducing the transmission power of the Bluetooth module so that the DECT module transmits signals through the first antenna and the second antenna. It is understood that when the call mode is DECT, by adding a second antenna as the DECT antenna, this dual-antenna separation can generate a spatial filtering effect, effectively suppressing narrowband interference in complex electromagnetic environments, enhancing the transmission power of DECT, reducing the impact of the Bluetooth module's transmission power on DECT, and enhancing link reliability. Simultaneously, when the Bluetooth module is idle, the first antenna is released to the DECT module for use, allowing the two antennas to work together and maximizing hardware resource utilization.

[0049] For example, in one or more embodiments of this application, when the call mode is DECT call, the transmission power of the Bluetooth module can be reduced to a first power. The specific value of the first power is not limited.

[0050] In one possible embodiment of this application, the call mode further includes: Bluetooth call; the switching control method further includes: when the call mode is Bluetooth call, reducing the transmission power of the DECT module and controlling the Bluetooth module to transmit signals through the first antenna. It is understood that disconnecting the DECT module from the first antenna reduces the transmission power of the DECT module, eliminates co-channel interference, and improves Bluetooth communication quality.

[0051] For example, in one or more embodiments of this application, when the call mode is Bluetooth, the transmission power of the DECT module is reduced to a second power. The specific value of the second power is not limited. For example, a fixed value can be set, and the transmission power of the DECT module can be reduced to that fixed value. Alternatively, the adjusted power of the DECT module can be determined based on the overall power consumption of the headset. The specific values ​​and methods of power adjustment are merely examples.

[0052] In one possible embodiment of this application, the multimode headset further includes: an antenna combiner; wherein the first antenna is connected to the Bluetooth module and the DECT module through the antenna combiner;

[0053] When the call mode is a combined DECT and Bluetooth call, controlling the DECT module to disconnect from the first antenna includes:

[0054] When the call mode is a combination of DECT and Bluetooth, an antenna disconnect signal is generated;

[0055] The antenna disconnect signal is transmitted to the antenna combiner so that the antenna combiner disconnects the DECT module from the first antenna according to the antenna disconnect signal; wherein, if the antenna combiner does not receive the antenna disconnect signal, the antenna combiner maintains the connection between the DECT module and the first antenna.

[0056] As can be understood, as shown in Figure 3, the working state of the multiplexed antenna is adjusted according to the connection status of the device's wireless module; an antenna combiner is used in the circuit to connect the Bluetooth module and the DECT module to the same antenna; when the DECT is connected to antenna 1 and the Bluetooth is not connected to antenna 1, both antenna 1 (i.e., the first antenna described in this application embodiment) and antenna 2 (i.e., the second antenna described in this application) are used by the DECT module; when the DECT is not connected to antenna 1 and the Bluetooth is connected to antenna 1, antenna 1 is used by the Bluetooth module, and the DECT module disconnects from antenna 1 and antenna 2; antenna 1 and antenna 2 can be distributed in both ears. For example, the first antenna is disposed in the left ear canal of the multimode earphone, and the second antenna is disposed in the right ear canal of the multimode earphone. Alternatively, the second antenna is disposed in the left ear canal of the multimode earphone, and the first antenna is disposed in the right ear canal of the multimode earphone.

[0057] DECT uses dual antennas because the dual-antenna design reduces interference and ensures a much wider reception range, far exceeding that of Bluetooth. Additionally, due to the earphone's small size, there isn't much space to install an antenna. To maximize DECT signal strength and range, dual antennas are necessary, as there isn't enough space for a separate Bluetooth antenna. Therefore, the Bluetooth and DECT modules share a single antenna.

[0058] Referring to Figure 2, which is a schematic diagram of the structure of a switching control device for a multi-mode headset provided in an embodiment of this application, the device includes: a data acquisition module 201, a call mode module 202, and a joint control module 203.

[0059] The data acquisition module 201 is used to acquire call data from the multi-mode headset; wherein, the multi-mode headset transmits call data through a communication module; the communication module includes: a first antenna, a second antenna, a Bluetooth module, and a DECT module; the first antenna is connected to the DECT module and the Bluetooth module respectively, and the second antenna is connected to the DECT module;

[0060] The call mode module 202 is used to determine the call mode of the multi-mode headset based on the call data; wherein, the call mode includes: DECT and Bluetooth combined call;

[0061] The joint control module 203 is used to control the DECT module to disconnect from the first antenna when the call mode is a DECT and Bluetooth joint call, so that the DECT module can transmit signals through the second antenna and the Bluetooth module can transmit signals through the first antenna.

[0062] It is understood that call data from a multi-mode headset can be acquired by the headset's CPU via a Bluetooth module or a DECT module. The CPU is configured as the master control unit for both the Bluetooth and DECT modules, establishing a communication connection with them via an internal bus (such as I²C or SPI). The Bluetooth and DECT modules can report call data to the CPU via the internal bus. Furthermore, call transmission data is automatically generated by the Bluetooth or DECT module upon detecting an external communication request or audio stream, and includes protocol type, link status, and device identification information. Call mode data is generated based on the user's operation of the mode switching button, indicating the user's preset target call mode.

[0063] This application obtains call data from the multi-mode headset and determines the current call mode of the multi-mode headset based on the call data. When the call mode is confirmed to be a DECT and Bluetooth joint call, the DECT module is disconnected from the first antenna. At this time, the DECT module only transmits signals through the second antenna, and the Bluetooth module only transmits signals through the first antenna. This ensures that the DECT module and the Bluetooth module do not share an antenna when operating simultaneously, thereby avoiding signal interference problems that occur when multiple communication modules of the multi-mode headset use antennas at the same time.

[0064] In one possible embodiment of this application, the call mode further includes: DECT call; the switching control device further includes: DECT control module; the DECT control module 204 is used to reduce the transmission power of the Bluetooth module when the call mode is DECT call, so that the DECT module transmits signals through the first antenna and the second antenna.

[0065] In one possible embodiment of this application, the call mode further includes: Bluetooth call; the switching control device further includes: Bluetooth control module; the Bluetooth control module 205 is used to reduce the transmission power of the DECT module when the call mode is Bluetooth call, so that the Bluetooth module transmits signals through the first antenna.

[0066] In one possible embodiment of this application, the multimode headset further includes: an antenna combiner; wherein the first antenna is connected to the Bluetooth module and the DECT module through the antenna combiner;

[0067] When the call mode is a combined DECT and Bluetooth call, controlling the DECT module to disconnect from the first antenna includes:

[0068] When the call mode is a combination of DECT and Bluetooth, an antenna disconnect signal is generated;

[0069] The antenna disconnect signal is transmitted to the antenna combiner so that the antenna combiner disconnects the DECT module from the first antenna according to the antenna disconnect signal; wherein, if the antenna combiner does not receive the antenna disconnect signal, the antenna combiner maintains the connection between the DECT module and the first antenna.

[0070] In one possible embodiment of this application, the multi-mode headset further includes: a mode switching button; the call data includes: call transmission data and call mode data;

[0071] The call mode module 202 includes: a judgment unit, a call transmission unit, and a call mode unit;

[0072] The judgment unit is used to judge the call data;

[0073] The call transmission unit is used to extract the data type of the call transmission data if the call data is call transmission data, and determine the call mode of the multi-mode headset based on the data type.

[0074] The call mode unit is used to determine the call mode of the multi-mode headset based on the call mode data if the call data is call mode data; wherein, the call mode data is generated in response to the user's operation of the mode switching button.

[0075] Understandably, by acquiring call data from the multi-mode headset, the system can determine the current call mode of the multi-mode headset based on the call data. When the call mode is confirmed to be a combined DECT and Bluetooth call, the system controls the DECT module to disconnect from the first antenna. At this time, based on the connection relationship of the multi-mode headset communication modules, the DECT module transmits signals through the second antenna, while the Bluetooth module transmits signals through the first antenna. This ensures that the DECT module and the Bluetooth module do not share an antenna when operating simultaneously, thereby avoiding signal interference problems that occur when multiple communication modules of the multi-mode headset use antennas at the same time.

[0076] Furthermore, in this embodiment of the application, when it is confirmed that the communication method of the multi-mode headset is DECT call or Bluetooth call, only one module is making a call at this time. Therefore, by reducing the transmission power of the module that is not making a call, it can be ensured that there is no signal interference between the two modules.

[0077] In one possible embodiment of this application, this embodiment also includes other structures of the multimode headset: as shown in FIG4, it also includes: a lithium battery, a DSP, a microphone, a speaker, a USB module and a selection configuration module;

[0078] The system includes a microphone for collecting user voice information; a speaker for playing the transmitted sound information; a lithium battery for providing power to the device; DSP (Digital Signal Processing) technology, and a DSP chip for implementing digital signal processing; a DECT module for connecting to a DECT base station via DECT communication; a Bluetooth module for connecting to a mobile phone via Bluetooth communication; and a USB module for connecting to a computer (PC) via USB communication.

[0079] In a specific application scenario, the headset includes a configuration module to receive user mode setting commands and configure the headset's operating modes: Mode 1: DECT, Mode 2: Bluetooth, Mode 3: DECT+BT (simultaneously used for multi-party conferences or one-way calls with one-way hold), and Mode 4: USB. Configuration selection commands are received from headset buttons, PC control software, mobile phone control software, or the touchscreen or buttons of the DECT base station. For example, Mode 1: DECT connects to a WH65Base or uses a DECT dongle or W80B DECT base station; Mode 2: connects to a mobile phone via Bluetooth, allowing for Bluetooth calls; multiple modes can work simultaneously, such as DECT+BT (i.e., Bluetooth). When multiple modes are working simultaneously, DECT takes priority. When dialing, it checks for a DECT connection and uses DECT for dialing if one is available; it supports simultaneous multi-mode operation. If there is a Bluetooth call and a call comes in via DECT, the headset rings to indicate the call. After answering the DECT call, the Bluetooth call remains in hold mode. It can also achieve DECT+Bluetooth+USB call conference mixing. If the DECT or Bluetooth wireless module is not connected for an extended period (10 minutes), it will automatically shut down to improve battery life.

[0080] In one possible embodiment of this application, the multi-mode headset further includes: a mode switching button; the call data includes: call transmission data and call mode data;

[0081] Determining the call mode of the multi-mode headset based on the call data includes:

[0082] The call data is judged; if the call data is call transmission data, the data type of the call transmission data is extracted, and the call mode of the multi-mode headset is determined based on the data type; if the call data is call mode data, the call mode of the multi-mode headset is determined based on the call mode data.

[0083] Specifically, when the multimode headset is within the DECT working area, call mode data corresponding to the DECT call is generated based on the positioning of the multimode headset; the positioning of the multimode headset is determined based on the Beacon signal received from the Beacon module.

[0084] In one possible embodiment of this application, mode selection can also be achieved by using Bluetooth Beacon positioning technology to identify the current location of the headset. Based on Bluetooth, the distance between the headset and the DECT base station is confirmed. When the headset is detected entering the DECT working area via Bluetooth, the DECT module is activated, and the headset is switched to DECT mode or BT+DECT mode. The selection configuration module is controlled by the user or by the headset's location. When roaming outside the DECT wireless range, the user can still use the same headset to make / receive calls on their mobile phone.

[0085] In one possible embodiment of this application, the Beacon module can be configured independently.

[0086] In one possible embodiment of this application, the Beacon module may be installed on a DECT base station.

[0087] Taking a base station containing a Beacon module as an example, the base station can continuously send Bluetooth signals (containing the same UUID; if there are multiple identical UUIDs in an area, other information can be attached to distinguish them) to the surrounding area. When the headset enters the designated area, it can receive the signal, and the headset locates, receives, and feeds back the signal. For example, based on the signal strength or identification of the Beacon, the multimode headset is determined to be within the DECT working area, and the headset can automatically generate mode configuration data to activate the DECT module accordingly.

[0088] When the DECT base station receives a feedback signal, indicating the headset has entered the DECT area, the headset is in the DECT zone, and the DECT module is activated. The DECT module consumes a significant amount of power, and users are unlikely to turn it off when leaving the office area. Adding a Beacon module to the base station or placing it in the office can help pinpoint the headset's location.

[0089] Here, Beacon positioning is used as an example only. In other embodiments, other positioning methods may be used, and there are no restrictions.

[0090] In one possible embodiment of this application, please refer to Figure 5, which shows the product form provided in this embodiment, enabling both commercial and home use of the headset. In an office environment, users typically have a personal computer and a wired telephone on their desks. The headset dock is a DECT base station coupled to the personal computer or telephone. The headset dock includes a wireless transceiver using the DECT protocol. The headset dock's wireless transceiver has a wireless communication range and communicates with the associated headset. Meeting rooms and break rooms within the office area are within the wireless communication range, while the parking lot is outside. When a user leaves the company with the headset, such as arriving at the parking lot, the DECT connection will automatically turn off after a long period of inactivity. When the user returns to the company, the Beacon module recognizes the Bluetooth device returning to the area and will activate the DECT module to reconnect (ordinary Bluetooth headsets or DECT headsets only go into sleep mode after a disconnection, not turn off; thus, the Bluetooth headset will automatically reconnect when it returns to the range).

[0091] To better explain, DECT (Digital Enhanced Cordless Telecommunications) is an enhanced digital cordless telephone standard developed by the European Telecommunications Standards Institute (ETSI). It is an open, evolving digital communication standard primarily used in cordless telephone systems. It provides a framework for cordless communication, offering high-quality voice and data services for high-user-density, short-range communication. USB (Universal Serial Bus) is a serial bus standard and an input / output interface specification widely used in personal computers and mobile devices, and extending to photographic equipment, digital televisions (set-top boxes), game consoles, and other related fields. Multi-mode (DECT+BT+USB) configurations are configurable by the factory. For example, if the DECT frequency band is not supported in China, the factory can disable the DECT baseband by writing different configuration files (same headphone software, different configuration files) using dedicated software, supporting only Bluetooth and USB modes to comply with local laws and regulations.

[0092] Understandably, the user's experience with multi-mode headphones includes: 1. Using PC control software to turn Bluetooth, USB, and DECT on / off to improve battery life; 2. Users can also turn the modules on / off using the mode switch button; 3. The wireless module automatically shuts off after a long period of inactivity to improve battery life.

[0093] The charging methods for the multi-mode headphones include: 1. Charging via USB. 2. Placing the headphones on a DECT base station and connecting via contacts for charging. Software upgrades for the multi-mode headphones include: 1. Upgrading the headphone software using PC control software. Specifically, Yealink USB Connect software is a device management and software upgrade software developed by Yealink. 2. Upgrading the headphone software by placing the headphones on a DECT base station and connecting via contacts. This embodiment enables switching between different modes for the multi-mode headphones, making them suitable for various scenarios.

[0094] Referring to Figure 6, in one possible embodiment of this application, a DECT&BT dual-mode headset is disclosed, which consists of two parts: a "DECT&BT dual-mode radio frequency link" and a "DECT&BT multi-frequency antenna".

[0095] The first part is the DECT & BT dual-mode RF link, which consists of a BT chip, a DECT chip, and a filter combiner. The BT chip internally contains a Bluetooth module, an RF transceiver, a processor, and memory, ensuring normal BT wireless communication. The DECT chip internally contains a DECT module, an RF transceiver, a processor, and memory, enabling normal DECT wireless communication. The filter combiner consists of a filter and a combiner. The filter significantly attenuates signals outside the main frequency to an acceptable noise floor range (the DECT filter significantly attenuates RF signals outside the DECT main frequency, resulting in an RF signal within the acceptable noise floor range for BT; the BT filter significantly attenuates RF signals outside the BT main frequency, resulting in an RF signal within the acceptable noise floor range for DECT). The combiner then combines the DECT and BT signals into a single signal, effectively isolating the two frequency bands. The second part is the DECT & BT multi-band antenna, which is an antenna that meets the bandwidth performance requirements of the DECT band (1.88G~1.93G, 1.78G~1.8G) and the BT band (2.4G~2.48G).

[0096] The DECT&BT dual-mode communication headset has the following three wireless communication working states, none of which interfere with each other.

[0097] The first operating state is as follows: When DECT is working, DECT conducts normal wireless communication through the path of "DECT RF Port" + "DECT filter and combiner" + "DECT & BT ANT (antenna)". At the same time, the DECT signal branch is attenuated to the noise floor range by the "BT filter in the filter combiner", which will not affect the transmission and reception of BT.

[0098] The second operating state is as follows: When BT is working, BT conducts normal wireless communication through the path of "BT RF Port" + "DECT filter and combiner" + "DECT & BT ANT". At the same time, the BT signal branch is attenuated to the noise floor range by the "DECT filter in the filter combiner", which will not affect the transmission and reception of DECT.

[0099] The second operating mode is when DECT and BT operate simultaneously without interfering with each other. Since DECT communicates normally via the path of "DECT RF Port" + "DECT filter and combiner" + "DECT & BT ANT", and the DECT signal branch is attenuated to the noise floor level by the BT filter in the filter combiner, it does not affect BT's transmission and reception. Similarly, when BT (Bluetooth) is operating, it communicates normally via the path of "BT RF Port" + "DECT filter and combiner" + "DECT & BT ANT", and the BT signal branch is attenuated to the noise floor level by the DECT filter in the filter combiner, it does not affect DECT's transmission and reception.

[0100] This embodiment introduces a "DECT&BT dual-mode communication system design," where DECT and BT can share a "radio frequency link and antenna." This ensures that when they work simultaneously, the wireless parameters are normal, and music playback and voice calls are normal, without any abnormal issues such as stuttering, packet loss, or electronic noise.

[0101] Another possible embodiment of this application also provides a switching control system for multi-mode headphones, including:
