Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of an audio processing device according to the present application. The audio processing apparatus 1 provided in the embodiment of the present application includes an audio board 10 and a plurality of audio receivers 20. The audio board 10 and a plurality of audio receivers 20 are connected in series in turn, each audio receiver 20 being for receiving audio of an environment and forming a first audio packet.

The audio receiver 20 may be a wired omni-directional microphone, the audio board 10 is connected with a plurality of wired omni-directional microphones through a network cable, and power supply and signal transmission to the omni-directional microphones are concentrated on the network cable, so that no additional power supply is needed to supply power to the audio receiver 20. The connection of the audio processing apparatus 1 is simplified, and the use of devices is saved, improving the practicality of the audio processing apparatus 1.

Optionally, the audio board 10 may comprise a first interface 11 and an audio processing module 12.

In this embodiment, the first interface 11 is connected to the audio receiver 20, that is, the first interface 11 and the audio receiver 20 may be connected through a network cable, one end of the network cable is connected to the first interface 11, and the plurality of audio receivers 20 are sequentially connected to the other end of the network cable. The audio processing module 12 is connected to the first interface 11 for receiving and processing the first audio packets from the audio receiver 20. After the audio receiver 20 receives the audio of the environment, a first audio packet is formed, the audio receiver 20 transmits the first audio packet to the audio processing module 12 through the network cable by means of the first interface 11, and when there are a plurality of first audio packets, the plurality of audio receivers 20 can transmit the first audio packets in the connection order on the network cable, or can transmit the plurality of first audio packets at the same time; after receiving the plurality of first audio packets transmitted from the audio receiver 20, the audio processing module 12 centrally performs audio processing on the plurality of first audio packets.

The plurality of audio receivers 20 directly form the first audio packet to be transmitted to the audio processing module 12 for centralized processing after receiving the audio, and audio processing devices are not required to be arranged in each audio receiver 20, so that the device cost of the audio processing device 1 is saved, meanwhile, the first audio packet is centralized processed, the situation that the plurality of audio receivers 20 process the first audio packet in different standards (caused by the fact that a certain audio receiver 20 fails or the like) is avoided, and when the corresponding first audio packet processed by the audio receiver 20 is transmitted to the audio board 10, the situation that the audio board 10 needs to additionally process the first audio packet in different processing standards occurs, the audio processing steps are simplified, and therefore the audio processing efficiency of the audio processing device 1 can be improved.

Optionally, referring to fig. 2, fig. 2 is a schematic structural diagram of a second embodiment of the audio processing device of the present application. The audio processing device 1 comprises a first power supply 30, the audio board 10 comprises a second interface 13, and the audio processing module 12 comprises a power supply chip 121 and a judging chip 122.

The first power supply 30 is connected to the power supply chip 121 through the second interface 13, and the power supply chip 121 steps down the voltage of the first power supply 30 to supply power to the audio processing module 12. The judging chip 122 is connected to the first interface 11 and the second interface 13, and is used for judging the connection state of the audio receivers 20 and the first interface 11, so that the first power supply 30 supplies power to the plurality of audio receivers 20 through the second interface 13, the judging chip 122 and the first interface 11.

In the present embodiment, the first power supply 30 is used to supply power to the audio receiver 20 and the audio processing module 12, and since the voltage required for the audio receiver 20 and the audio processing module 12 to operate is different, the voltage required for the audio processing module 12 to operate is smaller than the voltage required for the audio receiver 20 to operate. Therefore, the audio processing module 12 includes the power supply chip 121, the power supply chip 121 is connected to the second interface 13, the first power supply 30 transmits a voltage to the power supply chip 121 through the second interface 13, and the power supply chip 121 steps down to reduce the voltage transmitted by the first power supply 30 to a voltage suitable for the audio processing module 12 to work, so that the first power supply 30 supplies power to the audio processing module 12 through the power supply chip 121.

In another embodiment, the power supply chip 121 may be further connected to a voltage reduction circuit to reduce the voltage for the second time, so as to ensure that the voltage is within the working voltage range of the audio processing module 12, avoid damage to the audio processing module 12 caused by excessive voltage, and ensure the working safety of the audio processing module 12.

The determination chip 122 is connected to the first interface 11 and the second interface 13, the first interface 11 is connected to the plurality of audio receivers 20, and the second interface 13 is connected to the first power supply 30. The judging chip 122 can output the monitoring electric signal to judge the interface capacitance and resistance value of the audio receiver 20 connected to the first interface 11. The judging chip 122 determines whether the first interface 11 meets the power supply protocol standard through the returned characteristic impedance of the first interface 11, and if the returned characteristic impedance meets the power supply protocol standard, judges the input power required by the audio receiver 20 through the returned current value to supply power to the audio receiver 20; the returned characteristic impedance is determined to meet the power supply protocol standard, that is, the audio receiver 20 is correctly connected to the first interface 11, and the first power supply 30 can normally supply power to the audio receiver 20.

In another embodiment, each audio receiver 20 may also have a built-in judging chip to judge whether the audio receiver 20 connected in series with the audio receiver 20 is correctly connected, and the built-in judging chip is consistent with the interface identifying process, but the judging process is performed between two audio receivers 20. The built-in judging chip on the audio receiver 20 may be the same type of chip as the judging chip 122 of the audio processing module 12. According to the above method, the identification of each audio receiver 20 and the correct power supply can be accomplished.

Further, in the detection process of the judging chip 122, the first interface 11 may be judged according to POE (Power Over Ethernet, active ethernet) protocol standard; the interface resident detection level of the determination chip 122 is used for external interface detection. When the judging chip 122 judges the interface capacitance and resistance value of the audio receiver 20 connected to the first interface 11, the high potential end of the judging chip 122 is 48V, the low potential end is 35V to 45V, and the voltage difference between the two ends (rising from 2.5V to 15V dynamic fluctuation) is used as the external detection level.

When the judging chip 122 receives the returned characteristic impedance of the first interface 11 and detects that the interface capacitance and resistance value of the audio receiver 20 connected with the first interface 11 meet the power supply protocol standard, the audio receiver 20 is correctly connected with the first interface 11, and the electric potential of the low-potential end of the judging chip 122 is continuously pulled down; then, the judging chip 122 receives the returned current value, and determines the CLASS device type of the audio receiver 20 after judging that the audio receiver 20 connected to the first interface 11 meets CLASS device classification standards (device standards suitable for industrial and commercial use or suitable for home and personal use), so as to determine the power output power; and the low potential end of the judging chip 122 is pulled down to 0V, the voltage difference between the high potential end and the low potential end of the judging chip 122 is 48V, and the first power supply 30 supplies power to the audio receiver 20 through the judging chip 122.

In another embodiment, the judging chip 122 continuously monitors the characteristic impedance of the first interface 11, and when detecting that the characteristic impedance of the first interface 11 does not meet the power supply protocol standard, it indicates that the audio receiver 20 fails or the audio receiver 20 is not properly connected, and the low-potential end level continuously rises until the rise is 35V-45V, and the first power supply 30 stops supplying power to the audio receiver 20. And the judging chip 122 continuously monitors the characteristic impedance of the first interface 11, and when the characteristic impedance of the first interface 11 meets the power supply protocol standard, the first power supply 30 supplies power to the audio receiver 20 through the judging chip 122, and the specific judging process is as described above, which is not repeated here.

The judging chip 122 judges the connection state of the first interface 11 and the audio receiver 20, and after judging that the audio receiver 20 is correctly connected with the first interface 11, the normal working voltage is applied to the audio receiver 20 to make the audio receiver 20 work. The transmission of excessive voltage when the audio receiver 20 is not properly connected is avoided, the first interface 11 or the audio receiver 20 is damaged, and the safety of the audio processing device 1 is improved. Meanwhile, the resident high-voltage signals of the connecting wires are prevented, and the safety of site wiring construction personnel is protected.

Optionally, the audio processing module 12 further comprises a transmission chip 123 and a processing chip 124.

The transmission chip 123 is respectively connected to the first interface 11 and the processing chip 124, the audio receiver 20 transmits the first audio packet to the transmission chip 123 through the first interface 11, and the transmission chip 123 transmits the first audio packet to the processing chip 124 for audio processing.

The transmission chip 123 may include a PHY (physical layer) chip and a SWITCH (data exchange) chip, where the audio receiver 20 is connected to the first interface 11, so that the audio board 10 and the audio receiver 20 establish a wired network connection, and the audio receiver 20 transmits a first audio packet to the SWITCH chip of the transmission chip 123 through the first interface 11.

The SWITCH chip may be connected to the PHY chip through another port, where a network transformer may also be connected between the SWITCH chip and the PHY chip, and the SWITCH chip transmits the first audio packet received from the audio receiver 20 to the PHY chip, which in turn transmits the first audio packet to the processing chip 124.

The processing chip 124 may include a DSP (Digital Signal Processing ) chip, and the DSP chip may perform audio processing, such as echo cancellation, noise reduction, mixing, etc., on the received first audio packet, so that the back-end module does not need to perform excessive processing on the first audio packet, and the processing pressure of the back-end module is reduced. The PHY chip is connected with the DSP chip through the RMII port, the first audio packet is transmitted to the DSP chip through the RMII bus, and the DSP chip performs audio processing on the first audio packet. In another embodiment, in the case that the SWITCH chip also supports the RMII mode, the transmitting chip 123 may also include only the SWITCH chip, and after the audio receiver 20 transmits the first audio packet to the SWITCH chip through the first interface 11, the SWITCH chip transmits the first audio packet to the DSP chip for audio processing.

In summary, the plurality of audio receivers 20 are connected in series with the audio board 10, and the first audio packet is transmitted to the processing chip 124 of the audio board 10 for centralized audio processing, so that the device cost of the audio processing apparatus 1 is saved; and the connection state of the audio receiver 20 and the first interface 11 is judged by using the judging chip 122, and the working voltage is transmitted to the audio receiver 20 after the audio receiver 20 is judged to be correctly connected with the first interface 11, so that the safety of the audio processing device 1 is improved.
