[0046] As described in the background section, in the prior art, factory environments are typically noisy, making it difficult for workers to hear verbal instructions or warnings. Furthermore, high dust concentrations in factory environments can easily affect the responsiveness of touch devices. Consequently, the sensitivity of touch buttons is also affected, response time increases, and the reliability of voice playback is compromised, increasing the likelihood of misoperation and reducing production safety.
[0047] Reference Figures 1 to 5 In some embodiments of this utility model, a factory safety voice playback device includes: a control panel 100, a voice storage module 200, a voice recognition module 300, a power supply module 400, and at least one audio output module 500.
[0048] The control panel 100 is equipped with several audio trigger buttons, which are connected to the input terminal of the voice storage module 200. Each audio trigger button can respond to the user's pressing operation, thereby generating a corresponding audio selection signal, which is then sent to the voice recognition module 300.
[0049] In one embodiment, the control panel 100 is further provided with a control panel port H5 and several status indicator lights. Each audio trigger button is connected to one status indicator light, and the status indicator light can indicate the pressed state of the corresponding connected audio trigger button. That is, each audio trigger button is connected to a status indicator light. One end of the control panel port H5 is connected to several audio trigger buttons, and the other end of the control panel port H5 is connected to the input terminal of the voice storage module 200, so that several audio trigger buttons are all connected to the voice recognition module 300 through the control panel port H5.
[0050] In this embodiment, the audio trigger button is not a touch button. The audio trigger button can be a mechanical button or a pressure-sensitive button to respond to the user's pressing operation.
[0051] The voice storage module 200 is connected to the voice recognition module 300. The voice storage module 200 can store several segments of secure audio, wherein the number of secure audio segments can be the same as the number of audio trigger buttons. In this embodiment, the audio selection signal can correspond to the secure audio segment.
[0052] The output of the voice recognition module 300 is connected to at least one audio output module 500. The voice recognition module 300 can receive an audio selection signal, identify the corresponding safety audio from the voice storage module 200 according to the audio selection signal, and output the safety audio to the audio output module 500.

The power supply terminal of the power module 400 is also connected to several audio trigger buttons, and the power module 400 can also supply power to the control panel 100 to supply power to the several audio trigger buttons.
[0055] For example, a user triggers an audio trigger button, which generates an audio selection signal and transmits the audio selection signal to the voice recognition module 300. The voice recognition module 300 receives the audio selection signal, reads the safety audio stored in the voice storage module 200 according to the audio selection signal, determines the safety audio corresponding to the audio selection signal, and sends the safety audio to multiple audio output modules 500. The multiple audio output modules 500 amplify the safety audio so that they can play the safety audio simultaneously to alert the staff.
[0056] In this application, several audio trigger buttons respond to user press operations, allowing users to easily switch between playing safety audio. Furthermore, by setting trigger buttons, compared to touch buttons in existing technologies, the sensitivity is higher and the response time is shorter in factory environments with high dust concentrations. The voice recognition module 300 identifies the corresponding safety audio from the voice storage module 200 based on the audio selection signal generated by the user's trigger and outputs the safety audio to the audio output module 500 for playback. This achieves self-recognition of safety audio and flexible playback of stored safety audio, improving the reliability of voice playback, reducing misoperation, and enhancing production safety.
