[0023] Reference Figure 1 , Figure 6 and Figure 7 This utility model provides a voice-controlled rechargeable portable outdoor light 10. Users can hold the rechargeable portable outdoor light 10 outdoors to illuminate the surroundings. During activities such as camping, users can also hang the rechargeable portable outdoor light 10 at a fixed height as a fixed lighting source 200.

[0024] The rechargeable portable outdoor light 10 includes a housing 100 and a microphone 300, a speaker 400, a voice control module 500, and a processor located within the housing 100. The microphone 300 is configured to receive control voice commands and generate corresponding audio signals. The voice control module 500 is configured to receive audio signals and generate corresponding control and broadcast signals. The enable terminal of the voice control module 500 is electrically connected to the microphone 300, the output terminal of the voice control module 500 is electrically connected to the speaker 400, and the processor is electrically connected to the light source 200. The processor is configured to control the light emission state of the light source 200.

[0025] When the voice control module 500 receives an audio signal, it generates a corresponding control signal and a broadcast signal. The processor receives the control signal and controls the light source 200 to emit light, and the speaker 400 receives the broadcast signal and broadcasts the corresponding audio.

[0026] Understandably, control voice can be voice issued by the user or voice issued by an electronic device such as a mobile phone.

[0027] It is understandable that the processor is a microprocessor such as a single-chip microcomputer (MCU). The processor can be a separate electronic component or a functional module on an integrated circuit.

[0028] It is understandable that the light source 200 can be any light source 200 available on the market, such as LED or incandescent lamp.

[0029] In this embodiment of the utility model, the user can use voice control to control the rechargeable portable outdoor light 10 hanging high up. The control is convenient. When the portable outdoor light changes the light emission state of the light source 200, it broadcasts the corresponding preset audio to remind the controller or other users of the change in the light state, so as to avoid the user falling due to sudden changes such as dimming of the light.

[0032] The low-dropout regulator provides a stable 3.3V power supply to power sensitive components such as the transceiver, digital-to-analog converter, analog-to-digital converter, and automatic speech recognition. The processor communicates through the transceiver. The analog-to-digital converter converts the analog signal from the microphone 300 into a digital signal for processing by the automatic speech recognition module. The digital-to-analog converter converts the digital audio signal into an analog signal for playback by the speaker (speaker 400).

[0033] Specifically, Figure 2 The illustration shows that the voice control circuit uses a chip model of JTW93310, and the voice control chip 520 includes sixteen pins numbered 1 to 16. Figure 3 The diagram shows that the chip model of the voltage conversion circuit is ME2107A50M5G, and the voltage conversion chip 510 includes five pins numbered 1 to 5. Figure 4 The diagram illustrates an audio amplifier circuit. The chip model of the audio amplifier circuit is 8002D, and the audio amplifier chip 530 includes eight pins numbered 1 to 8.

[0034] Figure 3The illustrated voltage conversion circuit boosts the input voltage of the lithium battery (3.0V-4.2V) and fixes it to a stable output voltage of 5V. Pin 1 of the voltage conversion chip 510 is the enable pin, pin 2 is grounded, pin 3 is the power input (connected to the lithium battery), and pin 4 is the output pin (providing 5V voltage).

[0035] The voice control circuit receives audio signals from the pickup circuit, processes them, generates control signals, and transmits them to the processor to control the light source 200 to emit light. At the same time, it generates broadcast signals, which are transmitted to the speaker 400 via the audio amplification circuit to broadcast the corresponding audio.

[0036] Among them, pin 2 of the voice control chip 520 is connected to pin 4 of the voltage conversion chip 510 to obtain a 5V voltage. Pins 6 and 7 of the voice control chip 520 are connected to the processor to complete the transmission of control signals. Pins 12, 13 and 14 of the voice control chip 520 are connected to the pickup circuit to receive audio signals from the pickup circuit. Pin 16 of the voice control chip 520 is connected to pin 4 of the audio amplifier chip 530 to transmit broadcast signals.

[0037] Figure 5 The illustrated audio amplifier circuit amplifies audio power. Pins 5 and 8 of the audio amplifier chip 530 are connected to the positive and negative terminals of the speaker, respectively, to drive the speaker.

[0038] Referring to Table 1 below, the control voice commands include switch control voice commands, brightness control voice commands, color temperature control voice commands, volume control voice commands, and distress control voice commands. Specifically, the switch control voice commands are used to control the on and off of the light source 200, such as the control voice commands numbered 9-12 in Table 1. The brightness control voice commands are used to control the brightness of the light source 200, such as the control voice commands numbered 13-18 in Table 1. The color temperature control voice commands are used to control the color temperature of the light source 200, such as the control voice commands numbered 19-24 and 26 in Table 1. The volume control voice commands are used to control the broadcast volume of the speaker 400, such as the control voice commands numbered 27-32 in Table 1. The distress control voice commands are used to control the light source 200 to emit a distress light effect, such as the control voice command numbered 25 in Table 1. The distress light effect can be three short flashes (three rapid flashes), three long flashes (three longer flashes), and then three short flashes again, forming a "short-long-short" SOS signal.

When the connecting portion 121 rotates relative to the main body 110, the protrusions 122 slide from one groove 111 to another groove 111 and achieve mechanical self-locking, so that the light angle remains relatively stable after adjustment and will not shake. In addition, the connecting portion 121 and the lamp housing 130 also achieve self-locking through the same connection method, which will not be described in detail here.

[0050] refer to Figures 10 to 12 In one embodiment, the rechargeable portable outdoor light 10 further includes a support member 940, which is rotatably connected to the housing 100.
