Description

Technical Field

[0001] The utility model relates to the technical field of audio effect processing equipment, in particular to an audio effect processor and a speaker. Background Art

[0002] To meet the privacy needs of customers, many entertainment venues with audio-visual equipment are equipped with private rooms. For example, KTV usually has multiple private rooms, and movie theaters usually have multiple screening halls. Whether it is a private room or a screening hall, in order to pursue better sound effects, each private room or screening hall will be equipped with speakers, specifically including multiple speakers, power amplifiers and audio effect processors. Generally, after the use of a private room or a screening hall, it is necessary to test the speakers to ensure that they can play normally next time and avoid the abnormal operation of the private room due to the failure of the speakers. At present, most of the debugging and testing methods are carried out manually by staff on-site in the private room. This not only tests the professionalism of the staff, but also, since multiple speakers are installed in each private room, once the number of private rooms increases, it will bring a great workload to the staff. Especially during peak hours, there are many consumers, and on-site testing is time-consuming and laborious, bringing great troubles to both businesses and consumers.

[0003] In view of this, the designer has deeply conceived in view of the many deficiencies and inconveniences caused by the need for on-site testing of existing speakers, and actively researched, improved and trial-produced to develop the present invention. Summary of the Utility Model

The present utility model can assist the central control host 40 in automatically detecting the speaker 10 by improving the speaker 10 and the audio effect processor 20. If the central control host 40 determines that the test sound of the speaker 10 does not meet the requirements, it will notify the worker to perform maintenance, thus greatly reducing the workload of the test personnel.

[0029] As Figure 2 and Figure 3 shown in the figure, the present utility model also discloses an audio effect processor 20, which includes a chassis 23 and a main board installed in the chassis 23. A control chip is installed on the main board. The main board is provided with at least one pre-stage output interface 21, at least one audio input interface 24, at least one detection MIC input interface 22, and at least one MIC output interface 25 connected to the outside of the chassis 23. A communication module is also provided on the main board. The pre-stage output interface 21 is used to connect to the power amplifier 30, the power amplifier 30 is connected to the speaker 10, a test microphone 11 for sound pickup is installed on the speaker 10, the audio input interface 24 is used to input audio, the detection MIC input interface 22 is used to connect to the test microphone 11 of the speaker 10, the MIC output interface 25 is used to output the audio of the test microphone 11 or the audio of the processor 20, and the communication module is used to connect to the central control host 40.

[0030] Among them, there can be multiple speakers 10 supporting the audio effect processor, so as to output different sound effects, such as speakers for channels like left (L), right (R), C (center), left surround (SL), right surround (SR), subwoofer (SUB), etc. The number of the pre-stage output interfaces 21 corresponds to the number of the speakers 10. The multiple pre-stage output interfaces 21 are respectively connected to the power amplifier 30. The detection MIC input interfaces 22 also have multiple and correspond one-to-one to the test microphones 11 of the multiple speakers. The control chip is also connected to an electronic switch, and the electronic switch is arranged on the main board. Different test channels of the speakers can be switched through the electronic switch.

[0031] The audio effect processor of the present utility model is also equipped with a wireless microphone 50. The wireless microphone 50 has a wireless charging stand. The number of wireless microphones 50 can be one, two or even more. On the chassis 23, there are microphone input interfaces 26 corresponding to the number of wireless microphones 50, a charging control interface 27 for connecting to the wireless charging stand 51, and a MIC232 interface 28 for communicating with the wireless microphone 50.

[0032] A DSP chip connected to a connection control chip is installed on the main board. The DSP chip is connected to the microphone input interface 26 and the audio input interface 24. Through the DSP chip, the microphone sound and background sound can be mixed and effect processed.

[0033] The front of the chassis 23 of the present utility model is provided with a display screen, audio control buttons, sound effect control buttons, etc. connected to the main board. The microphone input interface 26 is preferably arranged on the front of the chassis 23.

[0036] Through the connection between the central control host 40 and the audio effect processor 20, and the connection between the speaker 10 and the audio effect processor 20, the automatic test of the speaker 10 can be realized. After the central control host 40 sends a test instruction to the specified speaker through the communication module, the audio effect processor 20 opens the corresponding channel. Then the central control host 40 sends a test signal. After the test signal is received by the audio effect processor 20, it is sent to the front-end output interface 21, amplified by the power amplifier 30, and then pushed into the speaker 10 to make a sound. In the present utility model, a test microphone 11 is added to the speaker 10 for sound pickup. In the test state, the test microphone 11 will pick up the sound emitted by the speaker 10 to generate a feedback signal and send it back to the audio effect processor 20. The audio effect processor 20 then returns the feedback signal to the central control host 40. The central control host 40 compares and analyzes the parameters of the feedback signal with the originally stored original parameters to determine whether the state of the tested speaker is normal. Automatically testing the state of the speaker 10 by the central control host 40 can replace the existing manual on-site test of the speaker 10. The staff can timely detect each speaker 10 in the private room according to the current state of the private room. If it is detected that the speaker 10 is in an abnormal state, the maintenance personnel will be notified for on-site maintenance, thus greatly reducing the workload of the staff. Through the improvement of the structures of the speaker 10 and the audio effect processor 20, the present utility model can assist the central control host 10 in automatically testing the speaker 10.
