It must have high reliability and durability, because the vehicle environment may have vibrations and other conditions, and it must be ensured that the control circuit will not malfunction during long-term use.

[0064] (8) USB interface: provides a wired data transmission and charging method. The USB interface can be connected to the vehicle computer or other devices to transmit data (such as transmitting the configuration information of the microphone, etc.), and it can also charge the built-in rechargeable battery of the microphone. The USB interface must comply with relevant USB standards to ensure compatibility with other devices; the interface must be firm and reliable, and will not become loose or have poor contact in the event of bumps during driving; it must have a certain data transmission speed to meet the data exchange requirements between the microphone and external devices, and ensure that the audio is stably input into the cockpit for song recognition.

[0065] (9) Bluetooth module: realizes wireless communication between the microphone and the vehicle computer or other Bluetooth devices. It is used to transmit sound signals, control commands and other information, so that users can use the microphone in the car without using a wired connection. The Bluetooth module must comply with the Bluetooth communication standard, have good compatibility, and be able to stably connect with a variety of Bluetooth devices; have strong signal transmission capabilities, and be able to ensure stable signal transmission in the complex electromagnetic environment of the car, avoid disconnection or signal interference, and ensure stable audio input to the cockpit for listening to songs and identifying songs; low power consumption, while ensuring communication functions, minimize the consumption of microphone power and extend the use time of the microphone.

[0066] (10) Power module: Provides a stable power supply for each component inside the microphone. Power can be obtained through the vehicle power supply (such as the cigarette lighter interface) or the built-in rechargeable battery, and converted into the operating voltage required by each component. The power module must have high power conversion efficiency to reduce energy loss and ensure that the microphone will not experience performance degradation or failure due to power supply problems during use; it must have safety functions such as overcharge protection and over-discharge protection to protect the safety of the battery and other components and extend the service life of the microphone; it must have good compatibility with the vehicle power interface, be able to obtain power from the vehicle power supply stably, and will not interfere with the vehicle electronic system during the charging process.

[0101] Specifically, since the singing function is recommended to be turned on only after the vehicle is stable and safe, the vehicle usage information needs to be determined, and whether the preset safety start conditions are met based on the vehicle usage information. When the preset safety start conditions are met, the karaoke function can be started, and then the cockpit microphone or the vehicle microphone is used to collect and identify audio information. If the preset safety start conditions are not met, the karaoke function cannot be started, and you can wait until the vehicle stops to determine whether the preset safety start conditions are met.

[0102] The current vehicle usage information includes vehicle status information and vehicle location information; when it is determined that the vehicle is in a parked state based on the vehicle status information, and when it is determined that the vehicle is in a safe position based on the vehicle location information and the preset map information, it is determined that the preset safety start condition is met; otherwise, it is determined that the preset safety start condition is not met.

[0110] In summary, this application can achieve: (1) One-click karaoke: When the user plays songs in the cockpit in any form (cockpit audio, mobile phone speaker, passenger humming, etc.), the user can enter the song recognition mode by long pressing the button on the microphone. The microphone inputs the audio information during the long press period into the cockpit with the song recognition function. After the cockpit software recognizes the song, it outputs the song name to the karaoke software, which searches for the song and starts singing. (2) One-click karaoke mode: Short press the multi-function button twice in a row to quickly open the karaoke software and turn on the cabin "karaoke mode" (the seats, air conditioning, and ambient lights are adjusted to the set values).

[0111] Reference Figure 2As shown in the flowchart, in this application, when a user hears a song he wants to sing, the user can take out the microphone (here it is the car microphone) and press it for a long time to listen to the song and identify the song. The subsequent car system (car smart cockpit system) performs an automated process, which includes: the microphone inputs the collected audio into the music software, the software identifies the music being played, outputs the music name to the karaoke software, and the karaoke software enters the corresponding song. This automated process avoids the drawback of the prior art that the user needs to open the car system or software, search for songs, and enter the song name before singing karaoke.

[0112] This application adopts a unique button operation method: a specific operation of the button on the car microphone housing, that is, long pressing the button to listen to the song and identify the song and enter the karaoke, and double-clicking the button continuously to open the karaoke mode customized by the car machine. This design integrates multiple functions on one button and triggers different functions through different operation methods.

[0113] The application breaks the limitation of traditional karaoke mode, allowing users to use various forms of audio as trigger sources, greatly enriching the in-car entertainment scene. Whether listening to music played by the cockpit audio system during a long journey, playing your favorite songs on your mobile phone in a relaxed atmosphere, or even humming impromptu, it can be an opportunity to start karaoke, bringing more joy and interaction to users; this unique button operation method is different from the operation of traditional in-car entertainment equipment, which greatly simplifies the user operation process and improves the user experience.

[0114] The vehicle microphone of the present application collects sound and transmits it to the vehicle computer for song recognition. The vehicle computer automatically inputs the recognition result into the karaoke software and enters the karaoke, and triggers the vehicle computer to start the customized karaoke mode through the microphone button operation. This involves efficient and stable data transmission between the microphone and the vehicle computer and fast collaborative work at the software level. The interactive process of the present application can ensure the advancement in the field of in-vehicle entertainment systems. The advantages of the present application are:

[0115] 1. Operation convenience is greatly improved:

[0116] In the prior art, to achieve the process from listening to songs to singing karaoke, users usually need to perform a series of complex operations on the car screen, such as searching for the entrance to the song recognition function in multiple menus, and then manually opening the karaoke software and searching for the recognized songs. This method is not only cumbersome to operate, but also easily distracts the driver's attention during driving, increasing safety risks.

[0117] This application sets a button on the car microphone. Users only need to press and hold the button to start the song recognition function. The car computer automatically recognizes the song and inputs the result into the karaoke software to enter the karaoke state; double-clicking the button continuously can directly open the karaoke mode customized by the car computer. This one-click operation greatly simplifies the operation process. Users do not need to perform complex operations on the car computer screen, which improves the convenience and efficiency of operation and reduces safety risks during driving.

[0118] 2. Wider application scenarios:

[0119] Existing technologies can often only identify songs from specific sources, such as music played by the car computer or audio played by specific music software. However, this application can identify songs played in any form in the cabin, including cockpit audio, mobile phone speakers, and passengers humming. This greatly broadens the usage scenarios and meets the entertainment needs of users in different situations. Whether you are listening to music played by the cockpit audio on a long journey, or playing your favorite songs on your mobile phone with friends, or even humming impromptu, you can easily start song recognition and enter karaoke mode, bringing users a richer and more diverse entertainment experience.

[0120] 3. Better intelligent interaction experience:

[0121] In the prior art, the functions of song recognition and karaoke are usually independent and require users to operate and set them separately. However, this application realizes the seamless connection between song recognition and karaoke software. After the car computer recognizes the song, it automatically inputs the result into the karaoke software, without the need for users to manually search and enter the song name. This intelligent interaction method not only improves the convenience of operation, but also brings users a smoother and more coherent entertainment experience.

[0122] A series of functions in this application integrate multiple technical fields such as audio recognition, cross-module signal connection, seat control, atmosphere light control and air conditioning control. The convenient operation of this application provides a pleasant and safe entertainment experience: when the traditional in-vehicle entertainment system turns on the karaoke function, users often need to perform a series of cumbersome operations, such as searching for songs, adjusting the volume, setting sound effects, etc. on the car computer. These operations are not only time-consuming, but also distract users and affect the entertainment experience. However, this application simplifies these complex operation processes into a simple button action through a one-button start method, allowing users to quickly enter the karaoke state at the moment of inspiration. Whether you are moved by the songs on the radio during a long journey, or humming to relieve boredom when you are stuck in a traffic jam, you can use simple button operations to transform these instantaneous music impulses into actual karaoke actions, greatly enriching the user's in-car entertainment experience; during driving, any complex operation may cause the driver to be distracted and increase the risk of traffic accidents. This application allows users to turn on karaoke-related functions without focusing too much attention on the car screen for complex operations, and only needs to perform simple button operations at the familiar microphone position. This effectively reduces the time the driver takes their eyes off the road to operate the entertainment system, reduces the possibility of traffic accidents caused by distraction, and provides a certain degree of protection for driving safety.
