All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
Referring to fig. 1, a schematic structural diagram of a wireless microphone with a valve according to an embodiment of the present invention includes: the antenna comprises a box body 1, an antenna 2 arranged on the box body 1 and a PCB device 3 arranged in the box body 1.
Fig. 2 is a schematic structural diagram of the PCB apparatus 3 according to the embodiment of the present invention. The PCB apparatus 3 includes a transmitting apparatus 31, a receiving assembly 32, a processor 33, an audio demodulating assembly 34, a tube application audio processing assembly 35, and an audio output assembly 36; wherein, the transmitting device 31 is connected with the antenna 2, and the transmitting device 31 is connected with the receiving component 32 in a communication way; the audio demodulation component 34, the valve application audio processing component 35 and the audio output component 36 are connected in sequence; the processor 33 is connected to the receiving component 32.
After the transmitting device 31 is started, the receiving component 32 receives a wireless signal, locks the frequency by the processor 33, and then transmits the wireless signal to the audio demodulating component 34 for demodulation, so as to obtain an audio signal; the valve application audio processing component 35 receives the audio signal and performs audio processing, and then transmits the obtained amplified signal to the audio output component 36 for audio output.
The electron tube in this embodiment is a cathode electron emission part, a control grid, an accelerating grid and an anode (screen) lead wire which are sealed in a glass container (glass tube) and welded on a tube base, an electric field is used for injecting an electron modulation signal into the control grid in vacuum, different parameter signal data after signal amplification or feedback oscillation are obtained at the anode, the electron tube generates a plurality of even harmonics during power-on operation, and according to acoustic fundamental tones: even harmonics and odd harmonics can be generated after the signals are amplified, the more even harmonics, the more pleasant the even harmonics, and the more even harmonics in the fundamental tones, the warmer, softer and mellow the tone quality of the human is; the more odd harmonics in the fundamental tone, the human ear can feel the feelings of coldness, burrs, hardness and the like; the electronic tube has certain overload bearing capacity, generates a curve waveform when being overloaded, and has a good improvement effect on the wireless microphone, so that the electronic tube is used for filtering and amplifying the wireless microphone, and a larger dynamic sense can be obtained without distortion.
In another embodiment, a transformer 4 is further disposed in the tank 1. The box body 1 is also provided with a switch device 5, a function key 6, an LCD display 7, an electronic tube display screen 8 or an aluminum panel 9. Wherein, the number of the antennas 2 is two, and the antennas 2 are UHF antennas 2. Wherein, the transmitting device 31 is connected with the receiving component 32 through wireless communication.
Compared with a wireless microphone with a traditional transistor, when the electronic tube wireless microphone in the embodiment is powered on to work, the electronic tube generates more even harmonics and less odd harmonics, and the transistor generates a large amount of odd harmonics according to acoustics: the more even harmonics in the fundamental tones, the warmer, softer and mellow the sound quality of human beings is heard, and the more odd harmonics in the fundamental tones, the more cold, burr and hard the human ears are felt; the tube is also better able to withstand overload than the transistor, and the transistor and digital device can be easily distorted at the maximum peak when the dynamics of the sound signal is large.

This is not done by conventional digital devices anyway. In digital devices, if the watch is red, it is certainly distorted or overloaded, whereas in tube devices, it is not, and sometimes red-bumping is allowed because the watch is red, but there is no distortion.
