[0036] The utility model provides an instant messaging device.

[0037] See also Figure 1 and Figure 2 In one embodiment of the present invention, the instant messaging device includes a housing 100, and is fixedly installed in the passenger area of ​​the aircraft through the housing 100; the instant messaging device also includes a control circuit, a microphone module 200, a speaker module 300, a trigger module 400 and a communication module 500 installed in the housing 100, the trigger module 400 is electrically connected to the control circuit, the trigger module 400 is used to output a corresponding trigger signal when triggered, the control circuit is used to control the working state of the microphone module 200 and / or the speaker module 300 according to the trigger signal, and the communication module 500 is used to access the instant messaging system of the aircraft.

[0038] In the present invention, an instant messaging device is installed in the passenger area. This device is connected to the aircraft's instant messaging system via a communication module 500. The pilot can also access the aircraft's instant messaging system. Thus, after a passenger is seated in the passenger area, they can communicate with the pilot via the instant messaging device, eliminating any barriers between the two. Crew members other than the pilot can also access the instant messaging system, allowing passengers to communicate with other crew members.

[0039] Furthermore, the control circuit controls the operating state of at least one of the microphone module 200 and the speaker module 300 based on the trigger module 400, allowing passengers to selectively open a channel between at least one of the microphone module 200 and the aircraft's real-time communication system. When a passenger needs to rest, the speaker module 300 channel can be closed to avoid being disturbed by the pilot's conversation. When the passenger is not resting, the speaker module 300 channel can be opened to allow the passenger to hear the pilot's conversation in real time. When a passenger needs to speak with the pilot, the microphone module 200 channel can be opened, and when the passenger does not need to speak with the pilot, the microphone module 200 channel can be closed.

[0040] In addition, each module is integrated into the housing 100, which facilitates the fixed installation of the instant messaging device in the passenger area. Specifically, the housing 100 can be mounted on the seat back, armrest, or the side or top of the cabin wall by snapping, screwing, welding, etc.

[0041] In related technologies, the cabin is equipped with headphones connected to the intercom system. Passengers need to wear the headphones to communicate with the pilot. Wearing them for a long time will cause discomfort to the passengers' heads, thus affecting the flight experience.

[0042] In the technical solution of the present utility model, the instant messaging device enables passengers to communicate directly and smoothly with the flight crew without wearing headphones, freeing up the passengers' ears and improving the head comfort when traveling on an aircraft. It can transmit and receive the user's voice more clearly, is simple to operate, has a compact structure, and is highly practical.

[0043] In one embodiment, the trigger module 400 includes at least one of a button trigger module, a joystick trigger module, a touchscreen trigger module, and a gesture recognition trigger module. It is understood that the instant messaging device can be configured with one or more of these modules. The button trigger module can be triggered by a passenger pressing it, the joystick trigger module can be triggered by actuating the joystick, the touchscreen trigger module can be triggered by touching the screen, and the gesture recognition trigger module can be triggered by a preset gesture. Of course, the trigger modules are not limited to these four types.

[0044] In one embodiment, see Figure 3The button trigger module 400 includes a pressing portion 410, a conductive spring 420 and a circuit board 430. The conductive spring 420 is located between the pressing portion 410 and the circuit board 430 and is fixedly connected to the pressing portion 410. The button trigger module 400 also includes an elastic body 440, which is provided on the back side of the pressing surface of the pressing portion 410. Under the action of the elastic body 440, the conductive spring 420 can be maintained at a position spaced apart from the circuit board 430, so that the button trigger module 400 can naturally maintain a non-triggered state. Without loss of generality, the button trigger module 400 is used to trigger the microphone module 200. When the passenger wishes to communicate with the pilot, the push portion 410 is continuously pressed, and the conductive spring 420 maintains contact with and conducts electricity to the circuit board 430, maintaining the microphone module 200 in an operating mode and transmitting the passenger's voice to the pilot. When the passenger and pilot have finished their conversation, the external force applied to the push portion 410 is removed. Under the action of the elastic member 440, the push portion 410 drives the conductive spring 420 away from the circuit board 430, restoring the conductive spring 420 to a state of being spaced apart from the circuit board 430, thereby re-closing the microphone module 200 and maintaining it in the closed state thereafter. Of course, in other embodiments, the button trigger module 400 may also operate such that each press toggles the microphone module 200 between on and off.

[0045] In one embodiment, the instant messaging device further includes an external expansion interface 600 electrically connected to the control circuit. This allows the instant messaging device to connect to external devices to expand its functionality. Without loss of generality, the external expansion interface 600 serves as an audio device access port for connecting passengers' portable headphones.

[0046] In one embodiment, the external expansion interface 600 includes at least one of a USB-C interface, a circular port interface, a Lightning interface, and a standard wireless short-range communication interface. Standard wireless short-range communication interfaces include, but are not limited to, Bluetooth interfaces and StarFlash interfaces. An instant messaging device can be configured with only one of these interfaces, with multiple instant messaging devices available for replacement. Alternatively, multiple interfaces can be configured simultaneously to allow passengers to connect different types of headphones. Of course, in other embodiments, the external expansion interface can also be of other types, including future standard interfaces.

[0047] In one embodiment, see Figure 2The microphone module 200 includes a single or multiple array microphones, each of which includes a pickup 210, an input signal filter 220, and an input signal amplifier 230 electrically connected in sequence. The communication module 500 includes a signal transmission module 510, which is connected to the input signal amplifier 230. In other words, the microphone module can be configured with only one microphone or a microphone array consisting of multiple microphones. The latter can provide excellent sound source localization and noise suppression effects.

[0048] Without loss of generality, the microphone module 200 is a noise-reduction dynamic type. The sound waves collected by the microphone 210 drive the diaphragm to vibrate, thereby driving the voice coil to move in the magnetic field, and converting the sound signal into an electrical signal; the input signal filter 220 is used to process the captured audio signal, reduce interference such as background noise and echo, improve sound quality, and enhance voice clarity. The input signal filter 220 uses a combination of low-pass filters and high-pass filters to optimize the voice signal, reduce background wind noise or aircraft noise, and use automatic gain control to adapt to different acoustic environments; the input signal amplifier 230 is composed of multiple amplification circuits, which amplify the sound signal captured by the microphone to facilitate subsequent audio processing and transmission.

[0049] In one embodiment, see Figure 2 The speaker module 300 includes an output signal amplifier 310, an output signal filter 320, and a speaker body 330, which are electrically connected in sequence. The communication module 500 includes a signal receiving module 520, which is electrically connected to the output signal amplifier 310. Without loss of generality, the speaker module 300 is an electrodynamic speaker. Electrodynamic speakers have a wide frequency bandwidth, higher efficiency, softer sound quality, and lower cost. The audio signal from the speaker body 330 interacts with the changing magnetic field generated by the voice coil and the permanent magnetic field in the magnetic circuit system, causing the voice coil to vibrate axially, driving the connected diaphragm to vibrate, thereby generating sound waves and realizing the speaker function. The output signal amplifier 310 amplifies the audio signal from the pilot so that the speaker body 330 can subsequently output the audio clearly. The output signal filter 320 performs frequency-selective processing on the audio signal from the pilot, reducing background noise through low-pass and high-pass filters, improving the output audio quality, and protecting the speaker from potential damage.

[0050] Specifically, when a passenger manually presses the pressing portion 410, the conductive spring 420 is triggered to conduct the circuit, the voice transmission channel is opened, and the microphone 210 collects the passenger's sound vibration signal and converts the sound vibration signal into an electrical signal. The electrical signal converted by the microphone 210 is transmitted to the signal sending module 510 in the communication module 500 through the input signal filter 220 and the input signal amplifier 230 in sequence. The signal sending module 510 transmits the electrical signal from the microphone module 200 to the instant messaging system and converts the electrical signal into an acoustic signal again, allowing the pilot to hear the instant voice information from the passenger. The pilot's instant voice information can also be converted into an electrical signal in the same way and transmitted to the signal receiving module 520 in the communication module 500 through the instant messaging system. The electrical signal received by the signal receiving module 520 is transmitted to the speaker body 330 in sequence through the output signal amplifier 310 and the output signal filter 320. The speaker body 330 converts the electrical signal into an acoustic signal and plays it, so that the passengers in the cabin can hear the voice information from the pilot, thus realizing a closed communication loop.

[0051] In one embodiment, a power module is installed in the housing 100 and is electrically connected to the control circuit. This can improve the endurance of the instant messaging device. When there is no external power supply to the instant messaging device, the built-in power module can still provide power, allowing the instant messaging device to continue operating.

[0052] In one embodiment, see Figure 1 The housing 100 is provided with an electrical connection cable 700, through which the instant messaging device can be connected to the aircraft's instant messaging system. This allows the instant messaging device to connect to the aircraft's instant messaging system via a wired connection, which helps ensure connection stability. Of course, in other embodiments, the instant messaging device can also be connected to the instant messaging system wirelessly, in which case the power module can also be charged via the electrical connection cable 700.

[0053] The present invention also provides an aircraft, which includes the aforementioned instant messaging device.

[0054] The present invention also provides an aircraft including an instant messaging device. The specific structure of the instant messaging device is similar to that of the aforementioned embodiments. Since the present aircraft utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects provided by the technical solutions of the aforementioned embodiments, which will not be detailed here. Without loss of generality, the aircraft is configured as an electric aircraft. This aircraft exhibits low noise levels, further facilitating the use of the instant messaging device. Of course, the aircraft can also be a conventional aircraft powered by an internal combustion engine; by improving the noise reduction of the instant messaging device, it can also be used.

[0055] The cockpit of the aircraft is equipped with a headset that is communicatively connected to the aircraft's instant messaging system. It is understood that the headset is also equipped with a microphone and speaker, allowing the pilot to access the aircraft's instant messaging system through the headset to facilitate conversations with passengers, as well as access the air traffic control system for ground-to-air communication or air-to-air communication with other aircraft. The headset can also be equipped with a trigger module, allowing the pilot to optionally communicate with passengers.
