Description

Technical Field

[0001] The present invention relates to the field of tuning equipment, and particularly to a combined wireless audio tuning system. Background Art

[0002] With the update and iteration of audio technologies, existing audio products have higher requirements for both sound quality and microphone effects. As a result, there are higher requirements for the tuning technology of audio products, which has increased the number of buttons for adjusting various volume gains, special sound effect buttons, and external interfaces.

[0003] Due to the increasing number of buttons for adjusting various volume gains, special sound effect buttons, and external interfaces, the area of the control panel of the audio has become larger and larger, which not only affects the overall appearance of the audio but also occupies more usage space.

[0004] In actual use and operation, integrating the control panel fixedly on the audio also has some drawbacks. For example, when adjusting the volume or sound effect, it is necessary to go to the side of the audio for adjustment. Since the user's position has changed from the original sound - emitting position to the tuning position, although the user feels that the volume and sound effect of the audio have been adjusted to the appropriate values, when the user returns to the sound - emitting position, the effect brought by the audio to the user still has a certain gap compared to the position when the user adjusted the audio. Therefore, it may be necessary for the user to perform multiple tunings to achieve the best effect. Summary of the Invention

[0005] Based on this, in view of the above - mentioned technical problems, it is necessary to provide a combined wireless audio tuning system, which can achieve the best tuning effect faster compared to the traditional tuning console for adjusting the audio.

[0006] A combined wireless audio tuning system includes:

[0007] A signal acquisition module, configured to acquire a pre - stage audio signal and a control - end audio signal of a mixing console;

[0008] A wireless transmission module, configured to transmit a radio signal to a matching wireless reception module, where the radio signal is converted according to the pre - stage audio signal and the control - end audio signal of the mixing console;

[0009] A wireless reception module, configured to receive the radio signal;

[0010] A main control module, configured to perform pre - processing before sound emission on the analog audio signal, where the analog audio signal is converted according to the radio signal, and the pre - processing before sound emission includes power amplifier processing and frequency division processing;

[0011] A sound emission module, configured to emit sound according to the analog audio signal;

[0012] Among them, the signal acquisition module and the wireless transmission module are arranged in the mixer, and the wireless reception module, the main control module and the sound generation module are arranged in the speaker.

[0013] In one embodiment, the mixer further includes a DSP central control decoder for performing mixed decoding processing on the pre-stage audio signal and the mixer control terminal audio signal to obtain a digital signal;

[0014] The wireless transmission module is further configured to convert the digital signal into the radio signal.

[0015] In one embodiment, the wireless reception module is further configured to convert the radio signal into the analog audio signal.

[0016] In one embodiment, the mixer further includes a mounting module, and the speaker further includes a positioning module. The mounting module can be mounted on the positioning module to fix the connection between the mixer and the speaker.

[0017] In one embodiment, the mounting module includes a groove structure and a first magnetic attraction member, and the positioning module includes a protruding structure matching the groove structure and a second magnetic attraction member attracted to the first magnetic attraction member. When the groove structure and the protruding structure are matched, the first magnetic attraction member and the second magnetic attraction member are attracted.

[0018] In one embodiment, the mixer further includes a first contact module, and the first contact module is electrically connected to the signal acquisition module;

[0019] The speaker further includes a second contact module, and the second contact module is electrically connected to the main control module. The second contact module is used to output the signal of the speaker;

[0020] When the mounting module is mounted on the positioning module, the first contact module is electrically connected to the second contact module, and the first contact module receives the signal of the speaker output by the second contact module, and the wireless transmission module and the wireless reception module are powered off.

[0021] In one embodiment, the mixer further includes a signal detection module, and the signal detection module is electrically connected to the first contact module and the wireless transmission module respectively. When the first contact module receives the signal of the speaker output by the second contact module, the signal detection module controls the wireless transmission module to be powered off.

[0022] In one embodiment, the wireless transmission module transmits active radio signals, the wireless reception module receives passive radio signals, and the wireless reception module is powered on only when a radio signal is received.

[0023] In one embodiment, there are multiple wireless reception modules, and each wireless reception module has a tag unit. The wireless transmission module has a tag identification unit for identifying the tag unit so that the wireless transmission module can send radio signals to the corresponding wireless reception module.

[0024] In one embodiment, the wireless transmission module is a UHF wireless transmitter, and the wireless reception module is a UHF wireless receiver.

[0025] The above combined wireless audio mixer system uses wireless transmission technology to convert the pre-stage audio signal and the audio signal of the mixer control terminal received by the mixer into radio signals, and sends them to the matching wireless receiver through the wireless transmission module. Then, the main control module performs power amplification processing and frequency division processing on the analog audio signal converted from the radio signal, and finally sends the processed analog audio signal to the sound generating module to make the sound generating module produce sound. Compared with the traditional mixer and audio, this mixer system does not need to set up connecting data lines, eliminating the trouble of being restricted by wires. When using the audio, the volume and sound effects of the audio can be directly adjusted through the mixer wirelessly connected to the audio, so as to make the mixing reach the best effect faster. At the same time, it solves the problem of howling that may occur when the user sings and mixes at the same time due to the too close distance between the speaker and the microphone of the traditional mixer and audio, effectively improving the convenient mixing experience brought by different environments and different distances.

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Next, in conjunction with Figures 1 to 8 A combined wireless audio mixer system of the present invention will be described.

[0037] As Figure 1 shown, in one embodiment, a combined wireless audio mixer system includes a signal acquisition module, a wireless transmission module, a wireless reception module, a main control module, and a sound generation module. The signal acquisition module and the wireless transmission module are disposed in the mixer, and the wireless reception module, the main control module, and the sound generation module are disposed in the sound system. The signal acquisition module is used to acquire the pre-stage audio signal and the mixer control terminal audio signal; the wireless transmission module is used to transmit a radio signal to a matching wireless reception module, and the radio signal is converted according to the pre-stage audio signal and the mixer control terminal audio signal; the wireless reception module is used to receive the radio signal; the main control module is used to perform pre-sound processing on the analog audio signal, and the analog audio signal is converted according to the radio signal. The pre-sound processing includes power amplifier processing and frequency division processing; the sound generation module is used to generate sound according to the analog audio signal.

[0038] The above combined wireless audio mixer system uses wireless transmission technology to convert the pre - amplifier audio signal and the audio signal at the control end of the mixer received by the mixer into radio signals, and sends them to the matching wireless receiver through the wireless transmission module. Then, the main control module performs power amplification and frequency division processing on the analog audio signal obtained by converting the radio signal, and finally sends the processed analog audio signal to the sound - generating module to make the sound - generating module produce sound. Compared with traditional mixers and speakers, this mixer system does not need to set up connecting data lines, eliminating the trouble of being restricted by wires. When using the speaker, the volume and sound effects of the speaker can be directly adjusted through the mixer wirelessly connected to the speaker, so as to achieve the best mixing effect faster. At the same time, it solves the problem of howling that may occur when the user tunes the sound while singing because the speaker and the microphone are too close in the traditional mixer and speaker, effectively improving the convenient mixing experience brought by different environments and different distances.

[0039] As Figure 2 shown, in one embodiment, a combined wireless audio mixer system provided by the present invention, the mixer further includes a DSP central control decoder for performing mixed decoding processing on the pre - amplifier audio signal and the audio signal at the control end of the mixer and obtaining a digital signal; the wireless transmission module is further used for converting the digital signal into a radio signal.

[0040] Specifically, the audio signal at the control end of the mixer includes Bluetooth input, TF card input, USB flash drive input, AUX input, multiple - channel combined wired microphone input, multiple - channel combined musical instrument port input, OTG digital input, wireless microphone input, etc., as Figure 7 shown. The DSP central control decoder transmits the digital signal obtained after mixed decoding to the wireless transmission module, and the wireless transmission module converts the digital signal into a radio signal and then sends it to the matching wireless receiver module.

[0041] As Figure 3 shown, in one embodiment, a combined wireless audio mixer system provided by the present invention, the wireless receiver module is further used for converting the radio signal into an analog audio signal.

[0042] Specifically, since the wireless receiver module is arranged in the speaker, the speaker can demodulate the received radio signal into an analog audio signal through the wireless receiver module, and then the main control module performs arithmetic amplification and frequency division processing on the analog audio signal. Finally, the sound - generating module produces sound according to the processed analog audio signal. For example, the power amplifier amplifies the electrical signal to drive each speaker unit of the speaker to produce sound.

[0043] In one embodiment, the combined wireless audio mixer system provided by the present invention further includes an installation module, and the audio also includes a positioning module. The installation module can be installed on the positioning module to connect and fix the mixer and the audio.

[0044] Specifically, the structural layout of the mixer can be as Figure 8 shown. Buttons, knobs and a display screen are distributed on the top surface of the mixer for convenient operation. Various interfaces are provided on the side of the mixer to optimize the internal space. The installation module is provided at the bottom, and a positioning module matching the installation module is provided on the top of the audio. The mixer and the audio can be connected through the matching installation module and positioning module. After connection, the integrity of the mixer and the audio is better, and it is convenient to carry, disassemble and assemble.

[0045] As Figure 4 shown, in one embodiment, the combined wireless audio mixer system provided by the present invention, the installation module includes a groove structure and a first magnetic part, and the positioning module includes a protruding structure matching the groove structure and a second magnetic part attracted to the first magnetic part. When the groove structure and the protruding structure match, the first magnetic part and the second magnetic part are attracted and combined.

[0046] Specifically, through the setting of the protruding structure and the groove structure, the mixer can be installed on the audio, and the setting of the magnetic parts makes the connection between the mixer and the audio more stable, and the mixer and the audio will not be separated due to slight external force during carrying or moving.

[0047] As Figure 5 shown, in one embodiment, the combined wireless audio mixer system provided by the present invention, the mixer further includes a first contact module, and the first contact module is electrically connected to the signal acquisition module; the audio further includes a second contact module, and the second contact module is electrically connected to the main control module. The second contact module is used to output the signal of the audio; when the installation module is installed on the positioning module, the first contact module is electrically connected to the second contact module, and the first contact module receives the signal of the audio output by the second contact module, and the wireless transmission module and the wireless reception module are powered off.

[0048] Specifically, as Figure 8 shown, a battery and a first contact module are also provided at the bottom of the mixer. When the first contact module and the second contact module are in contact, the connection method between the mixer and the audio is converted from wireless connection to wired connection. When the two are connected by wire, the connection between the wireless transmission module and the battery of the mixer is disconnected to avoid waste of resources.

[0049] In one embodiment, for a combined wireless audio mixer system provided by the present invention, the mixer further includes a signal detection module. The signal detection module is electrically connected to the first contact module and the wireless transmission module respectively. When the first contact module receives the signal of the audio device output by the second contact module, the signal detection module controls the wireless transmission module to power off.

[0050] Specifically, since the first contact module and the second contact module are used for the transmission of current and digital signals, when the mixer is installed at the corresponding position on the audio device, the first contact module and the second contact module are connected, and the signal detection module can detect that signal transmission has occurred between the first contact module and the second contact module. At this time, the signal detection module controls the wireless transmission module to power off. When the mixer is removed from the audio device, the first contact module and the second contact module are disconnected. When the signal detection module detects no signal transmission between the two, it controls the wireless transmission module to power on.

[0051] In one embodiment, for a combined wireless audio mixer system provided by the present invention, the wireless transmission module performs the transmission of active radio signals, the wireless reception module performs the reception of passive radio signals, and the wireless reception module powers on only when it receives a radio signal.

[0052] Specifically, considering that the signal detection module is arranged inside the mixer and is connected to the first contact module and the wireless transmission module, and is used to control the wireless transmission module to power off when the first contact module receives the signal transmitted by the second contact module. Since the wireless transmission module is matched with the wireless reception module, in a preferred state, when the wireless transmission module powers off, the wireless reception module should also power off to save power consumption, and when the wireless transmission module powers on and sends a signal to the wireless reception module, the wireless reception module powers on.

[0053] As Figure 6 shown, in one embodiment, for a combined wireless audio mixer system provided by the present invention, there are multiple wireless reception modules, and each wireless reception module has a tag unit. The wireless transmission module has a tag recognition unit, and the tag recognition unit is used to recognize the tag unit so that the wireless transmission module can send radio signals to the corresponding wireless reception module.

[0054] Specifically, in actual use, there may be a situation where one mixer is used to adjust the volume and sound effects of multiple audio devices, or it may be necessary for a dedicated staff member to perform the adjustment of the audio device all at once. Through the setting of the tag module and the tag recognition module, the wireless transmission module can specifically send signals to the designated wireless reception module without the need to operate multiple mixers.

[0055] In one embodiment, a combined wireless audio tuning system provided by the present invention has a wireless transmission module as a UHF wireless transmitter and a wireless reception module as a UHF wireless receiver.

[0056] Specifically, in this embodiment, ultra-high frequency is used for the transmission of radio signals. Among them, ultra-high frequency (UHF) refers to radio waves with a wavelength range of 1m to 1dm and a frequency of 300 to 3000 MHz, which are commonly used in the fields of mobile communication and radio and television.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
