Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and a preferred embodiment. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Figure 1, a multi-functional smart speaker, this speaker has the dual functions of a smart TV set-top box and a traditional speaker. While providing content for the TV, it can also provide high-quality audio output for the TV. The details are as follows: It includes a wireless signal transmission unit 1, a processor 2, an audio processing unit 3, a power amplifier circuit 4, and a speaker 5 connected in sequence; the wireless signal transmission unit 1 is used to receive control signals, audio and video data, etc. sent by external devices or wireless networks , and transmitted to the processor 2, the processor 2 sends corresponding control instructions according to the received control signal, or the received audio and video data is decoded by the sound effect processing unit 3 and amplified by the power amplifier circuit 4, and then played by the speaker 5 come out;

It also includes one or more audio interfaces 6 connected to the sound effect processing unit 3, one or more video interfaces 7 connected to the processor 2, and an extension interface 8, and the processor 2 communicates with a video display device (such as TV) connection.

Specifically, the audio interface can be used to input and connect audio signals output by digital products such as MP3, DVD, Tape, etc., and play them out through the sound effect processing unit, the power amplifier processing unit and the speaker to realize the traditional speaker effect; the wireless signal transmission unit 1 receives external The control signal, audio and video data, etc. sent by the device or the wireless network are output to the processor 2, and the processor 2 responds to the received control signal or audio and video data. The signal sends corresponding control commands, such as sleep, shutdown, fast forward or respond to corresponding control signals, etc. Of course, these functions have been maturely applied in existing electrical equipment, so this part does not involve the innovation and improvement of computer programs , when the received audio and video data, the processor 2 sends the audio signal in the audio and video data to the audio processing unit 3 for decoding, and after the decoded audio signal is amplified by the power amplifier circuit 4, it is played out by the speaker 5 , at the same time, the processor 2 transmits the image signal in the audio and video data to the video display device through the video interface 7, and displays it through the video display device to realize the function of a traditional smart TV set-top box.
