Problems solved by technology
[0003] This patented product involves multiple functions in sound detection. At present, there are many deficiencies in similar products, such as: most of the functions are relatively single, and can only detect the sample sound or the sound level; special signal transmission lines and servers are required, and the system The construction cost is high; after the signal is detected, it cannot communicate with the scene in real time, and can only communicate with other devices; only automatic detection is supported, and the device user does not support the active triggering of the alarm signal
[0004]
In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Embodiment 2
[0064] Embodiment 2 A method for implementing sound signal detection and feedback equipment
[0065] like figure 2 As shown, the present invention provides a method for implementing a sound signal detection and feedback device. The sound signal detection and feedback device of the present invention is always in the sound detection and feedback state when working, and enters the voice communication state when a communication request occurs. The Sound Detection Feedback section includes the following steps:
[0066] Start in step S101,
[0067] Step S101: the device is powered on, and step S102 is executed;
[0068] Step S102: the microphone collects the sound signal, and transmits the sound signal to the processing module, and executes step S103;
[0069] Step S103: Perform noise reduction processing on the sound signal collected in step S102 in the processing module to obtain a preprocessed signal, and simultaneously execute steps S104 and S107;
[0070] Step S104: Proces...

Abstract
The invention discloses a sound signal detection and feedback device, which comprises a processing module, a sound collecting module, an operation module, a display module, a playing module and a network card; the processing module is electrically connected to the playing module, the sound collecting module, the network card, the operation module and the display module respectively module. The invention also provides an implementation method of the sound signal detection feedback device. The invention can detect not only the specified sample sound and the size of the sound, but also the sound with specific amplitude, specific frequency and specific spectral characteristics; using traditional network cable as the transmission medium, no special line needs to be laid, and the server uses a general software program , only need to be installed and configured on the existing computer, no need to purchase dedicated server equipment; real-time voice communication, built-in echo cancellation algorithm on the device side, used to eliminate the sound played by the speaker recorded by the local device microphone; the device has buttons, Support users to manually trigger alarm signals and send out voice communication requests with the server.
Description
technical field [0001] The invention relates to a sound signal detection device, in particular to a sound signal detection feedback device and its implementation method, and belongs to the technical field of sound signal detection and feedback. Background technique [0002] With the development of smart devices, sound interaction has become an important means of interaction, and sound-related processing requirements are gradually increasing, such as detecting the sound level of a specified location, detecting whether there is a sound that matches the sample sound in a specified scene, The sample sounds may be illegal sounds such as smashing, babies crying, human speaking, etc. [0003] This patented product involves multiple functions in sound detection. At present, there are many deficiencies in similar products, such as: most of the functions are relatively single, and can only detect the sample sound or the sound level; special signal transmission lines and servers are re...
