[0026] Embodiment 1

[0027] Reference Figure 1 The sound-light conversion circuit in the embodiment comprises a power supply interface CN2, an audio input interface CN1, a first resistor R1, a second resistor R2, a capacitor U2, a third resistor R3, an external light source CN3, and a triode Q1.

[0028] The power supply interface CN2 is connected in series with the audio input interface CN1, the first resistor R1, and the second resistor R2 in sequence and then grounded. The ground end of the external light source CN3 is grounded through the triode Q1. The power supply end of the power supply interface CN2 is connected to the power supply access end of the external light source CN3. The power supply access end of the external light source CN3 is connected to the base of the triode Q1 through the third resistor R3. The high-level end of the second resistor R2 is connected to the base of the triode Q1 through the capacitor.

[0029] In this way, when the power supply interface CN2 supplies power to the audio input interface and the external light source CN3 after the audio input interface CN1 records the recording module, the recording module receives the voice and converts it into an electric signal. The electric signal is limited within a set amplitude by the first resistor R1 and the second resistor R2, realizing the first filtering and avoiding distortion caused by too strong signal. Then the electric signal is applied to the base of the triode Q1 through the capacitor U2 to control the on-off of the triode Q1. The capacitor U2 can block the direct current noise in the electric signal, ensuring that the on-off of the triode Q1 follows the change of the electric signal. When the triode Q1 is turned on, the external light source CN3 is grounded, thus being effectively powered and emitting light. When the triode Q1 is turned off, the external light source CN3 is extinguished. In this way, the electric signal converted by the recording module controls the on-off of the triode Q1, thus controlling the light and dark of the external light source, realizing the conversion from sound to light signal.

[0030] In the embodiment, the triode Q1 can specifically be an NPN triode, the emitter of which is grounded. The NPN triode works in the saturation region, acting as a switch tube with fast switching speed and high cost performance. The first resistor, the second resistor R2, and the third resistor R3 are all adjustable resistors, which are used to control the sampling range of the electric signal.

[0031] In this embodiment, once the recording playback is turned on, the light signal is continuously generated, that is, the recording signal is cyclically converted until it is turned off, which is beneficial to reducing the physical cost required for the user to call for help and increasing the chance of survival.

[0032] Example 2

[0033] Reference Figure 2 The communication device provided in this embodiment is a flashlight with sound-light conversion function.

[0034] Flashlights are common items with great uses. Existing flashlights have a lighting function. In this embodiment, the sound-light conversion circuit is combined with the flashlight, which is conducive to promoting the application value of the sound-light conversion circuit.

[0035] In this embodiment, the sound-to-light conversion circuit is housed within the flashlight, and the external light source CN3 serves as the flashlight's illumination source. Housing 1 also includes a recording switch 2, which is connected in series with the branch containing the first resistor R1 or the branch containing the capacitor U2. This switch controls whether the audio input interface CN1 is energized, thereby enabling the recording function. The power interface CN2 is integrated with the flashlight's internal power supply, improving module utilization and minimizing the size of the flashlight. This effectively utilizes the flashlight's existing modules, saving costs.

[0036] In this embodiment, the housing 1 is further provided with a light source switch 3 , which is connected in series between the power interface CN2 and the power supply input terminal of the external light source CN3 to control the illumination of the flashlight.

[0037] Example 3

[0038] Reference Figure 3 The flashlight adopts an explosion-proof flashlight, and the flashlight shell is provided with a safety hammer 4 and a blade 5. As an essential tool for survival in the wild, the explosion-proof flashlight is equipped with an acousto-optic conversion circuit, which can greatly improve the success rate of transmitting the distress signal.

[0039] In practice, a drone equipped with a photoacoustic conversion module can effectively receive and broadcast the distress signal from the photoacoustic-optical conversion circuit. Alternatively, the drone's onboard photoelectric conversion module can convert the optical signal into an electrical signal and send it back to the receiving center for a timely response to the distress signal. Alternatively, the drone can be replaced with a cloud machine to ensure signal reception.

[0040] In specific implementation, a power switch 6 can be further provided on the housing 1 to control the on / off of the power interface; a recording indicator light 7 and a sending indicator light 8 are provided to indicate the recording device and signal sending status respectively.

[0041] The above merely describes preferred embodiments of the present utility model, and is not intended to limit the present utility model, and any modification, equivalent replacement, and improvement within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
