Description

Technical Field

[0001] This utility model relates to the field of wireless conferencing systems, and in particular to a one-to-many open-type conferencing microphone. Background Technology

[0002] Bluetooth headsets apply Bluetooth technology to hands-free earphones, freeing users from the hassle of annoying wires and allowing them to easily make calls in various ways. Since their advent, Bluetooth headsets have been a valuable tool for mobile business professionals to improve efficiency. However, the open-back structure of current Bluetooth headsets on the market is not very secure when worn, and they are prone to falling out during exercise. Furthermore, because everyone's ear structure is different, the degree to which the existing structure fits into the ear can result in significant differences in the user experience.

[0003] Chinese utility model patent CN202223176468.5 discloses an open-back Bluetooth headset. It applies a paperclip structure, similar to that of an automatic door, to the open-back Bluetooth headset. When worn, the earcups, when placed on the outside of the ear, slide within a sleeve via upper and lower support rods, causing a spring to deform. After the main body of the headset is properly fitted, the spring's elasticity slides the fixing rod, allowing the earcups to conform to the ear's contours for optimal sound quality and a more secure and stable fit. However, this type of headset is generally intended for personal music listening and has not yet been applied to conference systems.

[0004] Chinese utility model patent CN202220881752.3 discloses a remote audio and video conferencing system. Its wireless transceiver connects wirelessly to the camera host and several omnidirectional microphone hosts, as well as to several extended microphones, enabling wireless transmission of audio and video signals. This overcomes the limitations of integrated or wired connections between cameras, speakers, and microphones, allowing for a cleaner and more aesthetically pleasing meeting room setup. By using extended microphones to collect audio signals and omnidirectional microphone hosts to play them, interference between audio signals is reduced, resulting in a better user experience. The number of omnidirectional microphone hosts and extended microphones can be adjusted according to the size of the meeting room, and multiple wireless cascades can be implemented, solving the problems of unclear hearing and insufficient microphone pickup distance in large meeting rooms, while also eliminating the limitations of wired connections and distance. Because the omnidirectional microphone host has both pickup and playback functions, if the meeting room is too small, only the omnidirectional microphone host can be used for the meeting, without connecting extended microphones. However, this conferencing system is based on omnidirectional microphones and does not integrate with open-back Bluetooth headsets, and communication requires multi-level cascading, making the communication method relatively complex. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a multi-user open-type conference microphone that enables a multi-person conference system through simple pairing of open-type TWS earphones and wireless transceivers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A type of open-type conference microphone that can be used with multiple microphones, including Wireless transceiver: It has an interface for connecting to a functional device, the wireless transceiver has a built-in transceiver-side wireless communication chip, and the wireless transceiver has a microphone but no speaker; Open-back TWS earphones: There is at least one open-back TWS earphone. The open-back TWS earphone has a built-in earphone wireless communication chip. The earphone wireless communication chip is wirelessly connected to the transceiver wireless communication chip. The open-back TWS earphone has a speaker but no microphone.

[0007] As a preferred option, the wireless transceiver is a charging case transceiver, and the microphone is an omnidirectional array of multiple microphones distributed on the main body shell of the charging case transceiver.

[0008] As a preferred embodiment, the charging case transceiver has one or more earphone charging cases, into which one or more open-back TWS earphones are placed in a corresponding manner.

[0009] As a preferred option, the interface of the wireless transceiver is connected to a wire, the other end of which is connected to one of the following functional devices: a computer, a mobile phone, a conference broadcasting terminal, or a communication terminal.

[0010] As a preferred embodiment, both the transceiver-side wireless communication chip and the earphone-side wireless communication chip have a broadcast communication unit, and the transceiver-side wireless communication chip communicates with the broadcast units of each earphone-side wireless communication chip through its broadcast unit.

[0011] As a preferred embodiment, the wireless transceiver has a transceiver main chip, and the microphone and transceiver-side wireless communication chip are electrically connected to the transceiver main chip.

[0012] As a preferred embodiment, the wireless transceiver includes a transceiver battery, a charging / discharging unit, and a charging case charging pin. The transceiver battery is electrically connected to the charging / discharging unit, and the charging / discharging unit is electrically connected to the charging case charging pin. When the open-back TWS earbuds are placed into the corresponding earbud charging case, the charging case charging pin is electrically connected to the earbud charging pin on the open-back TWS earbuds.

[0013] As a preferred embodiment, the open-back TWS earphone has an earphone main chip, and the speaker and the earphone wireless communication chip are both electrically connected to the earphone main chip.

[0014] As a preferred embodiment, the open-back TWS earphone has an earphone charging pin, an earphone battery, and a power supply unit. The earphone charging pin is electrically connected to the earphone battery, and the earphone battery is connected to the earphone main chip through the power supply unit.

[0015] As a preferred option, when there is only one open-back TWS earphone, it is defined as the first open-back TWS earphone, and the wireless transceiver is wirelessly connected to the first open-back TWS earphone in a broadcast manner. When there is a pair of open-back TWS earbuds, they are defined as a first open-back TWS earbud and a second open-back TWS earbud, and the wireless transceiver broadcasts and wirelessly connects to the pair of open-back TWS earbuds simultaneously. When there are three open-back TWS earbuds, they are defined as the first open-back TWS earbud, the second open-back TWS earbud, and the third open-back TWS earbud; the wireless transceiver broadcasts and wirelessly connects to the three open-back TWS earbuds simultaneously. When there are three or more open-back TWS earbuds, the wireless transceiver broadcasts and wirelessly connects to each open-back TWS earbud simultaneously.

[0016] This invention has significant advantages and beneficial effects compared with existing technologies. Specifically, as can be seen from the above technical solution, by placing the microphone on the wireless transceiver, the wireless transceiver has a microphone but no speaker; and by placing the speaker on the open-back TWS earbuds, the open-back TWS earbuds have a speaker but no microphone. This configuration simplifies communication. During downlink communication, the wireless transceiver obtains audio sources from functional devices such as computers, mobile phones, conference broadcasting terminals, and communication terminals, and then broadcasts the audio sources to each open-back TWS earbud. During uplink communication, since the open-back TWS earbuds are only used as speakers, they do not need to upload information to the wireless transceiver. The wireless transceiver, through the microphone, collects the audio signal and transmits it to the functional device via a wire. Therefore, multiple open-back TWS earbuds can be moved simultaneously using the simplest broadcasting method.

[0017] When used in conference settings, each participant wears an open-back TWS earphone to simultaneously receive the broadcast audio signal transmitted by the wireless transceiver. By placing the wireless transceiver on the conference table and connecting it to the functional device via a cable, the audio recorded by the transceiver's microphone can be uploaded to the functional device, thus realizing a multi-person conference system. This method results in a very simple and easy-to-operate conference system.

[0030] Please refer to Figures 1 to 8 As shown, this utility model discloses a one-to-many open-type conference microphone, including a wireless transceiver 10 and at least one open-type TWS earphone 20.

[0031] The wireless transceiver 10 has an interface 11 for connecting to the functional device 30. The wireless transceiver 10 has a built-in transceiver-side wireless communication chip 12, and the open-back TWS earphone 20 has a built-in earphone-side wireless communication chip 21. The earphone-side wireless communication chip 21 and the transceiver-side wireless communication chip 12 are wirelessly connected. The wireless transceiver 10 has a microphone 13 but no speaker, while the open-back TWS earphone 20 has a speaker 22 but no microphone.

[0032] During operation, the wireless transceiver 10 is connected to the functional device 30 via a wired connection, while the wireless transceiver 10 is connected to each open-back TWS earphone 20 via a wireless connection. Specifically, the interface 11 of the wireless transceiver 10 is connected to a wire, and the other end of the wire is connected to one of the functional devices 30, such as a computer, mobile phone, conference broadcast terminal, or communication terminal.

[0033] During downlink communication, the wireless transceiver 10 acquires audio sources from functional devices 30 such as computers, mobile phones, conference broadcasting terminals, and communication terminals, and then broadcasts the audio sources to each open-back TWS earphone 20. During uplink communication, since the open-back TWS earphones 20 are only used as speakers 22, they do not need to upload messages to the wireless transceiver 10. The audio signals collected by the wireless transceiver 10 through the microphone 13 are transmitted to the functional devices 30 through wires.

[0034] Preferably, the interface 11 on the wireless transceiver 10 is a Micro-USB interface, a Type-C interface, or an Apple universal interface, etc. The wires used to connect to the corresponding interface 11 are matching data cables. Through these data cables, the device 30 is wired to obtain the audio source of the corresponding device 30. Through the relay function of the wireless transceiver 10, these audio sources are broadcast to each open-back TWS earphone 20, and played by the speaker 22 of the open-back TWS earphone 20 to the ear.

[0035] Both the transceiver-side wireless communication chip 12 and the earphone-side wireless communication chip 21 have a broadcast communication unit. The transceiver-side wireless communication chip 12 communicates with the broadcast units of each earphone-side wireless communication chip 21 through its broadcast unit. Preferably, a new generation of LE Audio Bluetooth chip can be used, which integrates a broadcast communication unit and conventional Bluetooth communication functions. The advantages of broadcast communication are: firstly, broadcast has a wide range, fast propagation speed, and strong penetration ability. Secondly, due to the synchronous nature of broadcast communication, it can simultaneously send audio source information to many open-back TWS earphones 20, and each open-back TWS earphone 20 can receive the audio source information simultaneously, ensuring the synchronization of sound playback. Thirdly, broadcast communication occupies very little communication channel, so wireless communication basically does not need to consider the problem of insufficient channel, and communication can be achieved in the simplest way.

[0036] In some embodiments, the wireless transceiver 10 is a charging case transceiver 101, and the microphone 13 is an omnidirectional array of multiple microphones distributed on the main body shell 102 of the charging case transceiver 101. A standard microphone 13 is directional, meaning it has low sensitivity; sound is only produced when the speaker is close to the mouth, and its pickup radius is typically 30-50 centimeters. An omnidirectional microphone 13, as the name suggests, is omnidirectional, highly sensitive, and has a pickup radius of several meters, increasing its sensitivity by more than ten times. This makes it convenient for multiple people to share in meetings, saving time and effort, and is suitable for remote conferencing.

[0037] like Figure 3 As shown, the wireless transceiver 10 has a transceiver main chip 14, and the microphone 13 and the transceiver-side wireless communication chip 12 are electrically connected to the transceiver main chip 14. After the microphone 13 records the sound from the scene, it transmits it to the transceiver main chip 14. The transceiver main chip 14 converts the sound and then uploads it to the functional device 30. The functional device 30 receives the audio source from a remote location. The audio source is transmitted down to the transceiver main chip 14, converted by the transceiver main chip 14, and then transmitted down to each open-back TWS earphone 20 by the transceiver-side wireless communication chip 12.

[0038] The wireless transceiver 10 has a transceiver battery 15, a charging and discharging unit 16, and a charging case charging pin 17. The transceiver battery 15 is electrically connected to the charging and discharging unit 16, and the charging and discharging unit 16 is electrically connected to the charging case charging pin 17. When the open-back TWS earphone 20 is placed into the corresponding earphone charging case 103, the charging case charging pin 17 is electrically connected to the earphone charging pin 24 on the open-back TWS earphone 20.

[0039] like Figure 4As shown, the open-back TWS earphone 20 has an earphone main chip 23, and the speaker 22 and the earphone wireless communication chip 21 are both electrically connected to the earphone main chip 23. The earphone wireless communication chip 21 receives the audio signal broadcast from the wireless transceiver 10, transmits the audio signal to the earphone main chip 23 for audio processing, and then plays it to the ear through the speaker 22.

[0040] The open-back TWS earphone 20 has an earphone charging pin 24, an earphone battery 25, and a power supply unit 26. The earphone charging pin 24 is electrically connected to the earphone battery 25, and the earphone battery 25 is connected to the earphone main chip 23 through the power supply unit 26.

[0041] Application Example 1 like Figures 1 to 2 As shown, this illustrates the specific structure of the first application example of this utility model, which is a multi-open conference microphone, including a wireless transceiver 10 and one open-back TWS earphone 20. In this embodiment, the wireless transceiver 10 is a charging case transceiver 101, which has an earphone charging case 103 in which the open-back TWS earphone 20 can be stored. When there is only one open-back TWS earphone 20, it is defined as the first open-back TWS earphone 201, and the wireless transceiver 10 is wirelessly connected to the first open-back TWS earphone 201 in a broadcast manner. Application Example 2 like Figures 5 to 6 As shown, this illustrates the specific structure of a second application example of the present invention, which is a multi-open-type conference microphone, including a wireless transceiver 10 and two open-type TWS earphones 20. In this embodiment, the wireless transceiver 10 is a charging case transceiver 101, which has two earphone charging cases 103, and the two open-type TWS earphones 20 can be placed into the two earphone charging cases 103 respectively.

[0042] When the open-back TWS earbuds 20 are a pair, they are defined as a first open-back TWS earbud 201 and a second open-back TWS earbud 202, and the wireless transceiver 10 broadcasts and wirelessly connects to the pair of open-back TWS earbuds 20 simultaneously.

[0043] Application Example 3 like Figures 7 to 8As shown, this illustrates the specific structure of the third application example of this utility model, which is a multi-open conference microphone, including a wireless transceiver 10 and three open-back TWS earphones 20. In this embodiment, the wireless transceiver 10 is a charging case transceiver 101, which has three earphone charging cases 103, and the three open-back TWS earphones 20 can be placed into the three earphone charging cases 103 respectively.

[0044] When there are three open-back TWS earbuds 20, they are defined as the first open-back TWS earbud 201, the second open-back TWS earbud 202, and the third open-back TWS earbud 203; the wireless transceiver 10 broadcasts and wirelessly connects to the three open-back TWS earbuds 20 simultaneously.

[0045] Application Example 4 like Figures 9 to 10 As shown, this illustrates the specific structure of the fourth application example of this utility model, which is a multi-open conference microphone, including a wireless transceiver 10 and three or more open-back TWS earphones 20. In this embodiment, the wireless transceiver 10 is a charging case transceiver 101, which has three or more earphone charging cases 103, and the three or more open-back TWS earphones 20 can be placed into the three or more earphone charging cases 103 respectively.

[0046] When there are three or more open-back TWS earbuds 20, the wireless transceiver 10 broadcasts and wirelessly connects to each open-back TWS earbud 20 simultaneously.

[0047] In summary, the key design feature of this invention lies in the placement of the microphone 13 on the wireless transceiver 10, resulting in the wireless transceiver 10 having a microphone 13 but no speaker; and the speaker 22 on the open-back TWS earbuds 20, resulting in the open-back TWS earbuds 20 having a speaker 22 but no microphone. This configuration simplifies communication. During downlink communication, the wireless transceiver 10 acquires audio sources from functional devices 30 such as computers, mobile phones, conference broadcasting terminals, and communication terminals, and then broadcasts the audio sources to each open-back TWS earbud 20. During uplink communication, the open-back TWS earbuds 20, being used only as speakers 22, do not need to upload messages to the wireless transceiver 10. The audio signals collected by the wireless transceiver 10 through the microphone 13 are transmitted to the functional devices 30 via wires. Therefore, multiple open-back TWS earbuds 20 can be simultaneously driven using the simplest broadcasting method.

[0048] When used in conference settings, each participant wears an open-back TWS earphone 20 to simultaneously receive the broadcast audio signal transmitted by the wireless transceiver 10. By placing the wireless transceiver 10 on the conference table and connecting it to the functional device 30 via a cable, the sound recorded by the microphone 13 of the wireless transceiver 10 can be uploaded to the functional device 30, thus realizing a multi-person conference system. This method results in a very simple and easy-to-operate conference system.

[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
