[0045] Example
[0046] This embodiment aims to address the existing technology where drivers are not allowed to operate their mobile phones while driving. When they need to send or listen to voice messages, they must open their phones, which affects driving safety. Therefore, there is an urgent need for a car Bluetooth player that can play audio transmitted from the user's phone or received and played by the user's phone. To this end, referring to... Figures 1-3 As shown, this embodiment provides a car Bluetooth player with intercom functionality. The player can be plugged into the car's cigarette lighter socket and powered via a power connector. A user's mobile device can pair with the player's Bluetooth module for wireless connection. An audio transceiver component collects and processes the user's audio information, transmitting it to the user's mobile device via Bluetooth. The user can then transmit the audio to another mobile device for playback via a built-in app, enabling intercom functionality. Furthermore, the voice information received by the user's mobile device's app can be processed by an audio processing component via Bluetooth, and then the audio transceiver component generates an FM signal, which can be received and played by the car's audio system. This achieves two-way audio transmission, allowing users to communicate via intercom without manually operating their mobile devices while driving, effectively reducing driving safety risks.

The audio transceiver component 3 can collect the user's audio information and transmit it to the user's mobile device via the Bluetooth module 4, enabling the audio information to be used for communication on the user's mobile device's APP; furthermore, the audio transceiver component can receive the audio information from the mobile device and generate an FM signal via the FM transmitter module 6, which can be received and played by the car's audio system. In some embodiments, the audio processing component 2 includes a control circuit board 21, on which a main control chip is mounted, and the Bluetooth module 4 and the FM transmitter module 6 are mounted; the main control chip is used for audio decoding and audio compression. For example, when a user's mobile device (such as a mobile phone, tablet, or laptop) receives a voice message from another party through its built-in communication APP, the user's mobile device transmits the voice message to the main control chip via Bluetooth module 4 for decoding, filtering, and amplification. Then, it generates an FM signal via FM transmitter module 6. This FM signal can be received and played by the car's audio system. The user can hear the other party's audio without having to open the screen of the mobile device to perform any operation, making driving safer.
[0050] In some embodiments, the audio transceiver component 3 includes a sound acquisition unit 31. The sound acquisition unit 31 is capable of acquiring the user's audio; an audio processing component is electrically connected to the sound acquisition unit 31; the sound acquisition unit 31 is capable of acquiring the user's audio and transmitting it to the audio processing component, which is capable of processing the acquired audio and transmitting it to the user's mobile device via Bluetooth module 4. For example, the sound acquisition unit 31 may be a microphone, microphone, or pickup; the main control chip of the audio processing component is used to convert the user's voice signal into an electrical signal, which is then modulated by the audio processing component and transmitted to the user's mobile device via Bluetooth module 4. That is, the APP built into the mobile device then sends the modulated audio signal to the APP of other users' mobile devices. The user can transmit the recorded voice without opening the mobile device, allowing them to focus on the road while driving and ensuring driving safety. In some embodiments, the audio transceiver component 3 also includes an intercom button 32, which is electrically connected to the audio processing component.

When the button portion 71 is pressed, it pushes against the user input switch 72, triggering it and sending a signal to the FM transmitter chip. For example, the user input switch 72 can be a surface-mount tactile switch. The user input switch 72 includes one or more functions such as volume adjustment, play / pause, power switch, pairing mode switching, intercom activation, and channel adjustment. Each user input switch 72 corresponds to one button portion 71, and the surface of the button portion 71 is provided with a function logo for identification and use.

In some embodiments, the display 8 is also electrically connected to the audio transceiver component 3. When the audio transceiver component 3 is collecting user audio information, the display 8 outputs a "CALL" indicator to prompt the user that they are recording intercom voice.
[0054] Reference Figures 2-3As shown, the power receiving component 5 is electrically connected to the audio processing component 2 and the audio transceiver component 3; the power receiving component 5 is adapted to the car cigarette lighter socket, and can be inserted into the car cigarette lighter socket to power the car Bluetooth player. In some embodiments, the housing 1 includes a first outer shell 12 and a second outer shell 13, the second outer shell 13 being detachably connected to the first outer shell 12; the audio processing component 2 and the audio transceiver component 3 are disposed between the first outer shell 12 and the second outer shell 13; the first outer shell 12 includes a plug-in portion 121 extending from one end of the first outer shell 12, the plug-in portion 121 being adapted to the car cigarette lighter socket; the power receiving component 5 is disposed within the plug-in portion 121.

[0055] In some embodiments, the housing 1 further includes a button cover 14, which covers the surface of the second housing 13. In some embodiments, the vehicle Bluetooth player includes a first circuit board a and a second circuit board b, the first circuit board a is disposed inside the second housing 13, the second circuit board b is detachably disposed on the first circuit board a and electrically connected to the first circuit board a; one end of the second circuit board b extends into the interior of the plug-in portion 121.
[0056] Reference Figures 2-3 As shown, the power-connecting component 5 includes a flexible lever 51 and at least one power-connecting part 52, which is electrically connected to the second circuit board b. The plug-in part 121 is provided with a movable groove 1211 adapted to the at least one power-connecting part 52. At least a portion of the power-connecting part 52 can extend out of the movable groove 1211 under the restoring force of the flexible lever 51.

The first circuit board a is responsible for digital signal processing, while the second circuit board b is dedicated to power adaptation. It should be added that the working process of the power connection component 5 is as follows: When the cigarette lighter is inserted, the negative contact 522 retracts into the movable slot 1211 under external force. The elastic lever 51 is compressed and stores energy. After reaching the positioning point, the negative contact 522 pops out under the action of elastic force, and the negative contact 522 reliably contacts the inner wall of the cigarette lighter. When pulled out: the external force overcomes the elastic force, causing the negative contact 522 to retract, and the negative contact 522 fully enters the movable slot 1211, allowing the device to be safely removed. This solution achieves a reliable electrical connection between the car audio system and the cigarette lighter interface. Through a flexible power connection structure and modular circuit board design, it ensures stable power supply and convenient maintenance.
