[0002] Transceivers are important communication devices in railway transportation. In railway scenarios, staff can use them to achieve real-time and stable communication during operations such as train dispatching, construction and maintenance, and emergency response.

[0003] In existing technical solutions, the receiver base and handset are connected using a spring wire, which has the following disadvantages:

[0004] (1) Physical properties: After long-term use, the elasticity of the spring wire may gradually decrease, and it may not be able to return to its initial state well, affecting its stretching and contraction functions. Furthermore, during repeated stretching and bending, the internal conductors are prone to fatigue fracture, resulting in poor circuit contact and signal transmission failure.

[0005] (2) In terms of ease of use: If the spring wire is not restored in time after being stretched, it may curl, deform, or twist together, making it difficult to organize and causing inconvenience to use.

[0006] (3) Electromagnetic compatibility: The complex structure of the spring wire makes it difficult to effectively shield, increasing the risk of electromagnetic radiation and interference. Especially during high-frequency signal transmission, the spring wire is prone to generating electromagnetic radiation, which may become a source of interference and affect other equipment. The spring wire is also quite sensitive to electromagnetic interference and is easily affected by external electromagnetic fields, leading to signal distortion or equipment malfunction.

[0007] To address the aforementioned problems, the inventors designed a wireless transmitter and receiver. Utility Model Content

[0008] The purpose of this invention is to provide a wireless transceiver to solve the problems in the prior art where the transceiver uses a spring wire connection, which is prone to being difficult to manage and breakage.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a wireless transceiver, comprising:

[0010] Transmitter / receiver base and transmitter / receiver body located on the upper right side of transmitter / receiver base;

[0011] The transmitter and receiver base has a signal receiving line with a cable interface compatible with existing MMIs on its left external side.

[0012] The upper outer side of the microphone and the inside of the microphone base are respectively equipped with Bluetooth modules that search for the unique MAC address in the pairing record.

[0013] Charging metal contacts are provided at the connection between the main body of the transmitter and receiver and the base of the transmitter and receiver. The main body of the transmitter and receiver transmits data through the Bluetooth module and the base of the transmitter and receiver.

[0014] In the hanging-up state, charging and data communication, including MAC address transmission, are achieved by contacting the charging metal contacts.

[0018] A speaker is connected to the lower center of the microphone.

[0019] Preferably, a fixing block is provided on the lower outer side of the microphone end and the receiver end respectively, and an elastic band is connected to the inner side of the two fixing blocks. A fixing bolt is provided at the connection between the elastic band and the fixing block of the microphone end.

[0020] Preferably, the microphone end and the receiver end are connected by bolts and corrugated pipes respectively, and the microphone end and the receiver end can be stretched and bent to a certain extent through the corrugated pipes.

[0023] Preferably, the speaker integrates a sound-producing component, and the microphone is provided with dial buttons on the upper external side.

[0024] Compared with the prior art, the present invention provides a wireless transceiver with the following advantages:

[0025] 1. The wireless transceiver of this utility model adopts a dual-mode communication architecture. In the on-hook state, charging and data communication (including MAC address transmission) are achieved through contact points. In the off-hook state, button detection and audio signal transmission are achieved through Bluetooth. Contact detection triggers Bluetooth pairing as a dual-mode switching mechanism.

[0026] 2.

[0027] 3. The wireless transceiver of this utility model adopts a compatible interface design, retains the traditional connection method, and is compatible with the existing MMI cable interface.

[0028] 4. The corrugated pipe connector allows users to easily bend and stretch the microphone and receiver ends according to their needs.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] This utility model provides, for example Figure 1-9 The wireless transceiver shown includes a transceiver base 2 and a transceiver body 1 disposed on the upper side of the transceiver base 2.

[0043] The transmitter and receiver base 2 has a signal receiving line 15 for connecting external devices for communication and power supply on its left side.

[0044] A corrugated pipe connection end 3 is provided at the middle end of the main body 1 of the transmitter and receiver. The internal structure of the corrugated pipe connection end 3 is designed to bend and stretch, and it is made of flexible material. The internal structure is made of a tough plastic structure and contains the wiring inside the main body 1 of the transmitter and receiver. During bending or stretching, the corrugated pipe connection end 3 allows the transmitter and receiver ends to move relative to each other, while ensuring that the internal circuits and wiring are not damaged, maintaining the overall electrical connection and normal function of the transmitter and receiver, thereby realizing various shape transformations such as semi-circle.

[0045] A microphone end 8 is provided on the right side of the bellows connection end 3, and a receiver end 9 is provided on the left side. The microphone and receiver body 1 is powered by an internal power supply.

[0046] A Bluetooth module 7 is installed on the upper external side of the microphone end 8;

[0047] A rubber shield 11 is provided on the lower side of the microphone end 8. An air inlet one-way valve 10 is provided on the upper side of the rubber shield 11, which is connected to the microphone end 8. Multiple air outlets 12 are opened on the lower side of the rubber shield 11.

[0048] A speaker 13 is connected to the lower center of the microphone 8, and a dial button 14 is provided on the upper exterior of the microphone 8.

[0049] like Figure 1-9 As shown, a fixing block 6 is provided on the lower outer side of the microphone end 8 and the receiver end 9, and an elastic band 4 is connected to the inner side of the two fixing blocks 6. A fixing bolt 5 is provided at the connection between the elastic band 4 and the fixing block 6 of the microphone end 8. The microphone end 8 and the receiver end 9 are connected to the bellows connection end 3 by bolt connection, and the microphone end 8 and the receiver end 9 can be stretched and bent to a certain extent by the bellows connection end 3.

[0050] Preferably, when a user wants to hang the microphone body around their neck, they first bend the microphone body around the corrugated pipe connection end 3 to make it roughly ring-shaped or easy to hang around the neck. Then, the elastic band 4 is passed through the two fixing blocks 6, and the fixing bolts 5 are tightened in the appropriate position. The tension of the elastic band 4 is adjusted to securely fix the bent microphone body around the neck, making it easy to carry and preventing it from falling off. When the elastic band 4 wears out or the user wants to replace it with an elastic band 4 of different length and elasticity, the fixing bolts 5 can be loosened, the old elastic band 4 removed, a new elastic band 4 installed, and then re-secured.

[0051] Preferably, users can hold the microphone end 8 or the receiver end 9 with their hands and use the corrugated tube connection end 3 as the movable node to perform bending or stretching operations according to their own needs and usage scenarios. For example, when it is necessary to bring the microphone or receiver close to the face for a call, it can be bent to make it fit the facial contours better; when it is not in use, it can be stretched and adjusted to make it easier to place.

[0052] The receiver body 1 is connected to the transmitter / receiver base 2 via the transmitter end 8 and the receiver end 9 using a nested connection method. A charging metal contact 16 is provided at the connection between the receiver end 9 and the base of the transmitter / receiver body 1. The transmitter / receiver body 1 transmits data with the transmitter / receiver base 2 via the Bluetooth module 7.

[0053] like Figure 1-9As shown, the rubber shield 11 is hollow and is connected to the microphone end 8 via a nested connection.

[0054] Preferably, during a call, the user can squeeze the rubber cover 11 with their face to reduce its internal space, causing air to be squeezed out from the multiple air vents 12 on the lower side. When the user releases their hand, the rubber cover 11 will return to its original shape due to its elasticity and the action of the one-way air inlet valve 10. During the return process, external air enters the rubber cover 11 through the one-way air inlet valve 10, completing the reset. For example, when feeling stuffy around the ear, the user can promote airflow around the ear by repeatedly squeezing and releasing the rubber cover 11.

[0055] Optionally, the rubber shield 11 is made of elastic rubber material that can deform under external pressure. The one-way air inlet valve 10 only allows air to enter the rubber shield 11 from the outside, and does not allow internal air to flow out in the opposite direction. When the rubber shield 11 is squeezed, the internal air pressure increases, and gas is discharged from the outlet 12; after being released, the rubber shield 11 elastically returns to its original position, the internal air pressure decreases, and under the action of the air pressure difference, external air enters through the one-way air inlet valve 10, maintaining the air pressure balance inside the rubber shield 11, realizing the repeated squeezing and returning operation, and achieving the purpose of improving air circulation around the ear.

[0056] The speaker 13 integrates a sound-producing component. When the user uses the receiver 1 to make a call or listen to audio, the sound-producing component integrated inside the speaker 13 starts to work, converting the received electrical signal into a sound signal and playing the audio in the ear canal so that the user can hear the sound clearly.

[0057] The sound-producing components (such as moving coil or moving iron transducer structures) integrated inside the speaker 13 generate corresponding mechanical vibrations based on the received electrical signals. These vibrations are transmitted to the ear canal through media such as air, causing the eardrum to vibrate, and are ultimately perceived as sound by the human auditory system.

[0058] In this embodiment, the main body 1 of the transmitter and receiver and the base 2 of the transmitter and receiver also contain several key components. Among them, the MCU (microcontroller) is the core control unit and is set in the base 2 of the transmitter and receiver. It is connected to the Bluetooth audio module through a serial port to realize precise control of the Bluetooth module 7, such as turning the Bluetooth connection on and off and adjusting the audio transmission parameters.

[0059] The main body 1 of the transceiver includes a microphone assembly. The microphone is responsible for collecting the user's voice audio input and converting the sound signal into an electrical signal. The speaker 13 performs the opposite function, restoring the received electrical signal back into audio sound for playback. On the left and right sides of the main body 1, there are call buttons and PTT (Push-To-Talk) buttons, respectively. These buttons are all connected to the GPIO (General Purpose Input / Output) pins of the MCU. When the user presses a button, the corresponding electrical signal change is detected by the MCU's GPIO pins.

[0060] The MCU continuously monitors the button status via GPIO. Once a button press is detected, causing a change in the electrical signal, the MCU sends the button detection result to the Bluetooth module 7 via serial port. For example, when a user presses the call button, the MCU recognizes the change in the GPIO pin level corresponding to that button, processes it internally, and then sends the information indicating that the call button has been pressed to the Bluetooth module 7 via serial port. Upon receiving this information, the Bluetooth module 7 performs corresponding operations according to a preset program, such as initiating a call request.

[0061] The internal power supply section of this device plays a crucial role, controlling the battery charging and discharging process. When the transceiver unit 1 is connected to the transceiver base 2, the base charges the battery through metal contacts, and the power supply section manages the charging current and voltage to prevent overcharging or over-discharging, thus protecting battery life. On the other hand, the power supply section provides a stable operating voltage to the various circuits within the transceiver unit 1, ensuring the normal operation of the entire transceiver unit 1.

[0062] Preferably, when the transceiver unit 1 is in the on-hook state, i.e., placed on the transceiver base 2, the charging contacts are connected, and the transceiver base 2 begins charging the battery of the transceiver unit 1. Simultaneously, one serial port from each of the MCUs of the transceiver base 2 and the transceiver unit 1 is connected to the communication contacts. At this time, when the MCU of the transceiver unit 1 detects an external power input (i.e., detects that it is on-hook on the base), it sends the MAC address of the Bluetooth module 7 of the transceiver unit 1 to the transceiver base 2 via the serial port of the communication contacts. The MAC address is a unique identifier for the Bluetooth audio module, similar to a device's ID card. After receiving the MAC address, the transceiver base 2 compares it with the MAC address of the Bluetooth audio module that was previously paired.

[0063] If the MAC address comparison results are the same, it means that the transmitter / receiver unit 1 is the same device that was paired last time, and the transmitter / receiver base 2 confirms that the Bluetooth pairing connection is complete. This MAC address comparison method can quickly and accurately identify paired devices, avoiding repeated and tedious pairing processes.

[0064] If the MAC address comparison results are different, the transceiver base 2 will delete the previous Bluetooth pairing information and then establish a new Bluetooth pairing connection with the current transceiver main unit 1. After completing the new pairing, the transceiver base 2 will record the MAC address of the currently connected device to ensure that the transceiver base 2 and the transceiver main unit 1 always maintain a one-to-one connection, prevent pairing conflicts, and ensure the stability and security of communication.

[0065] When the main body 1 of the transceiver is picked up from the transceiver base 2, the transceiver body 1 and the transceiver base 2 have completed Bluetooth pairing and connection. In the off-hook state, the two communicate via Bluetooth to realize button detection and audio data exchange. For example, when the user presses a button on the transceiver body 1, the button detection result is transmitted to the transceiver base 2 via Bluetooth, and the transceiver base 2 performs the corresponding operation according to the received button information; at the same time, the user's voice audio data collected by the microphone is also transmitted to the transceiver base 2 via Bluetooth, and then processed by the base, such as being transmitted to an external communication network; conversely, the voice audio data received by the transceiver base 2 is also transmitted to the speaker 13 of the transceiver body 1 via Bluetooth for playback.

[0066] If the main unit 1 of the transceiver is powered on again while off-hook, the transceiver base 2 and the main unit 1 will re-pair and reconnect by searching for the unique MAC address in the pairing record. Both the main unit 1 and the transceiver base 2 store the MAC address information of previously successfully paired devices. By searching and comparing the MAC address, both parties can quickly re-establish the Bluetooth connection, restore normal communication functions, reduce user waiting time, and improve the user experience.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
