[0071] Whether to choose a built-in antenna or an external antenna, the Bluetooth antenna 104 in this embodiment has undergone strict testing and optimization to ensure that it can meet the high requirements of users for Bluetooth connection. In actual application, users can choose the most suitable antenna form according to their own use scene and preference, so as to enjoy more convenient and efficient wireless audio playback experience.

[0072] In summary, by providing two configuration options of built-in antenna and external antenna, the Bluetooth antenna 104 in this embodiment not only provides users with more flexible and diverse wireless connection options, but also ensures the high performance of the sound equipment in various complex environments.

[0073] Please refer to Figure 2 In an embodiment of this embodiment, the multi-scene sound equipment further comprises an audio signal processing circuit 6; this design not only further improves the audio processing capability of the sound equipment, but also brings users a more delicate and accurate sound quality experience.

[0074] The AUX input interface 101 is connected with the main control circuit 3 through the audio signal processing circuit 6.

[0075] Specifically, the audio signal processing circuit 6 as the key bridge between the AUX input interface 101 and the main control circuit 3, undertakes the heavy task of audio signal preprocessing and optimization. Through relevant circuit elements and algorithms, the circuit performs detailed filtering, equalization processing and dynamic range compression on the original audio signal received from the AUX input interface 101, so as to ensure that the audio signal has reached the best sound quality state before being transmitted to the main control circuit 3, and brings users a more pure and natural sound quality experience.

[0076] In summary, by introducing the audio signal processing circuit 6 and optimizing the connection between the AUX input interface 101 and the main control circuit 3, the multi-scene sound equipment in this embodiment significantly improves the processing capability and sound quality performance of the audio signal.

[0077] Please refer to Figure 2 In an embodiment of this embodiment, the car audio input circuit 2 comprises a car interface 201;

[0078] The automobile interface 201 is connected with the main control circuit 3 through the audio signal processing circuit 6.

[0079] Specifically, the automobile interface 201, as a core component of the automobile audio input circuit 2, is designed with full consideration of the particularity and compatibility of the automobile audio system.

[0080] Similarly, the audio signal processing circuit 6, as a key bridge between the automobile interface 201 and the main control circuit 3, undertakes the heavy task of audio signal preprocessing and optimization, aiming to perform detailed filtering, equalization processing and dynamic range compression, etc. on the original audio signal received from the automobile interface 201, so as to ensure that the audio signal has reached the best sound quality state before being transmitted to the main control circuit 3. This process not only improves the clarity and detail performance of the audio signal, but also effectively reduces noise interference and distortion.

[0081] Please refer again to Figure 2 In an embodiment of this embodiment, the multi-scene sound equipment further comprises an automobile inverter power supply circuit 7 and a power supply conversion circuit 8; this design not only greatly expands the application scenarios of the sound equipment, enabling it to easily access the automobile power supply system, but also ensures the stable operation of the equipment in various voltage environments, bringing users a more convenient and efficient audio playing experience.

[0082] The automobile inverter power supply circuit 7 is connected with the automobile interface 201, for converting the direct current accessed from the automobile interface 201 into alternating current;

[0083] The power supply conversion circuit 8 is connected between the automobile inverter power supply circuit 7 and the audio output circuit 4, for converting the voltage of the alternating current into the required output voltage.

[0084] Specifically, the automobile inverter power supply circuit 7, as a key component connecting the automobile interface 201 and the internal circuit of the audio equipment, undertakes the heavy task of efficiently converting the direct current (usually 12V or 24V) provided by the automobile into alternating current. This conversion process is crucial for the normal operation of the audio equipment, as many electronic components and circuits inside the audio equipment require alternating current to drive. The automobile inverter power supply circuit 7 achieves efficient and stable conversion from direct current to alternating current by adopting advanced power electronic technologies such as PWM (Pulse Width Modulation) control, thereby ensuring the normal operation of the audio equipment under the automobile power supply system.

[0085] The power supply conversion circuit 8 is located between the automobile inverter power supply circuit 7 and the audio output circuit 4, and plays a key role in converting the voltage of alternating current into the required voltage for the audio equipment output. Since different audio equipment and audio output circuits have different voltage requirements, the power supply conversion circuit 8 ensures the stable operation of the audio equipment under various voltage environments by precisely controlling the voltage conversion ratio and stabilizing the output voltage. This design not only improves the compatibility and adaptability of the audio equipment, but also provides users with a more stable and reliable audio playback experience.

[0086] In summary, by introducing the automobile inverter power supply circuit 7 and the power supply conversion circuit 8, and optimizing the connection between them and components such as the automobile interface 201 and the audio output circuit 4, the multi-scene audio equipment in this embodiment not only significantly improves its application performance and compatibility in the automobile environment, but also provides users with a more convenient and efficient audio playback experience.

[0087] Please refer again to Figure 2 In an embodiment of this embodiment, the multi-scene audio equipment further includes a power-on circuit 9; this design not only improves the intelligent level of the audio equipment, but also ensures efficient and stable operation of the device in the automobile environment, providing users with a more convenient and reliable audio playback experience.

[0088] The power-on circuit 9 is connected to the automobile interface 201, the audio signal processing circuit 6, and the automobile inverter power supply circuit 7, respectively, and is activated when the automobile interface 201 is connected to the automobile, and starts the automobile inverter power supply circuit 7 when the audio signal processing circuit 6 receives an audio signal.

[0089] Specifically, the power-on circuit 9, as a key component connecting the automobile interface 201, the audio signal processing circuit 6, and the automobile inverter power supply circuit 7, undertakes the core responsibility of device power management. When the automobile interface 201 is successfully connected to the automobile, the power-on circuit 9 will be activated immediately. This activation process not only marks that the audio equipment is ready to receive power from the automobile power supply system, but also lays a solid foundation for subsequent device startup and audio playback.

[0090] When the audio signal processing circuit 6 receives an audio signal, the power-on circuit 9 quickly identifies and responds to this signal, immediately starting the automotive inverter power supply circuit 7. This design ensures that the audio equipment can obtain stable power supply at the first time of receiving the audio signal, quickly entering the working state, and bringing users a seamless and smooth audio playing experience.

[0091] In addition, the introduction of the power-on circuit 9 also brings additional energy-saving benefits. When the device does not receive an audio signal or is in standby state, the power-on circuit 9 intelligently controls the on-off state of the automotive inverter power supply circuit 7 to avoid unnecessary power consumption. This design not only prolongs the endurance time of the car battery, but also reduces energy consumption, in line with the environmental protection concept of modern society.

[0092] In summary, by introducing the power-on circuit 9 and optimizing its connection with the automotive interface 201, the audio signal processing circuit 6 and the automotive inverter power supply circuit 7, the multi-scene audio equipment in this embodiment not only realizes intelligent power management, but also improves the running efficiency and stability of the device in the car environment.

[0093] Please refer to Figure 2 In an embodiment of the present embodiment, the multi-scene audio equipment further comprises a built-in power supply 10; this design not only further enhances the portability and flexibility of the audio equipment, but also ensures the stable operation of the device in various environments without external power supply, bringing users a more worry-free and free audio playing experience.

Through the precise battery management system, the built-in power supply 10 can monitor the battery power in real time and automatically enter the low-power mode when the power is insufficient to prolong the battery usage time.

[0096] In terms of power supply, the built-in power supply 10 is closely connected with the power supply conversion circuit 8. When the audio equipment is in an environment without external power supply, such as outdoor camping, picnic or long-distance travel, the built-in power supply 10 will become the main power source of the audio equipment. At this time, the power supply conversion circuit 8 will intelligently adjust the output voltage and current to ensure that the built-in power supply 10 can efficiently supply power to the audio equipment.

[0097] In addition, the introduction of the built-in power supply 10 also brings additional convenience to the sound equipment.
