[0025] The drawback of existing technologies is that the demonstration of the principle of vacuum tube signal amplification is mostly theoretical explanation, circuit diagram display or model demonstration, lacking interactive scenarios that allow users to intuitively feel the signal attenuation and amplification process. Therefore, users find it difficult to understand the actual role of vacuum tubes in signal transmission, and cannot gain a deep understanding of the physical process of signal amplification through comparative experience.
[0026] In response, the inventors proposed an interactive experience device based on electronic signal amplification, allowing users to intuitively experience the difference between signal attenuation and amplification through hands-on operation, thereby gaining a deeper understanding of the actual role of vacuum tubes in signal transmission.
[0027] The main application areas of this utility model include electronic technology education and science and technology exhibitions. It is suitable for use in classrooms, science and technology museums and other scenarios to demonstrate the principle of vacuum tube signal amplification and help users intuitively understand the relevant technology.
[0028] The features of this utility model include: the whole is composed of an interactive component, a circuit component, a switching component, and a power supply component; the interactive component includes an input device and an output device, used to simulate the sending and receiving of experience signals by both parties in the interactive experience. The specific input device and output device adopt different devices depending on the transmitted signal. For example, when transmitting audio signals, both the input device and the output device can be telephones, or the input device can be a pickup, such as a microphone, and the output device can be a speaker, such as a speaker or headphones; when transmitting voltage signals, the input device uses a DC power supply that outputs a demonstration voltage signal, such as a battery or a DC switching power supply, and the output device uses a voltmeter or oscilloscope; the circuit... The circuit component comprises two independent lines: a straight-through line using ordinary wires to simulate long-distance signal transmission without amplification (signal attenuation), and an amplification line connected in series with a vacuum tube power amplifier to simulate long-distance signal transmission amplified by a vacuum tube (signal amplification). The switching component includes a single-pole double-throw switch or a switching socket (for switching lines) and line status indicator lights (red for the straight-through line and green for the amplification line). The power supply component provides operating voltage to the vacuum tube power amplifier and the interactive component. The vacuum tube power amplifier is installed in the middle of the amplification line, with its input connected to the signal output of the input device and its output connected to the signal input of the output device, ensuring complete signal amplification. Furthermore, a visualization component can be included to show users a visual representation of the signal transmission effect. The design concept of this invention is to utilize signal transmission scenarios to simulate signal attenuation and vacuum tube amplification principles for interactive teaching.
[0029] Figure 1 This is a schematic diagram of the interactive experience device according to the first embodiment of this utility model. Figure 1 As shown, in the first embodiment of this utility model, an interactive experience device based on electronic signal amplification for audio signal transmission is proposed, specifically including: a telephone, a line assembly, a switching assembly, and a power supply assembly, wherein:
[0030] The telephone includes two simplified analog telephones 1 and 2, which are connected for communication via a wiring assembly. Analog telephones 1 and 2 retain only microphone and speaker functions for simulating the sending and receiving of audio signals by both parties in a call. In this embodiment, analog telephone 1 can be used as an input device, retaining only the microphone function, and analog telephone 2 can be used as an output device, retaining only the speaker function. Alternatively, analog telephone 1 can be used as an input device, and analog telephone 2 as an output device, or a fully functional telephone can be used as both an input and an output device. This invention is not limited to these limitations.
[0031] The circuit assembly includes an amplification circuit 3 and a direct-through circuit 4. The amplification circuit 3 is connected in series with a power amplifier 3-1 to simulate long-distance signal transmission amplified by a signal amplifier. The power amplifier 3-1 is installed in the middle of the amplification circuit 3. The input terminal of the power amplifier 3-1 is connected to the signal output terminal of the analog telephone 1, and the output terminal of the power amplifier 3-1 is connected to the signal input terminal of the analog telephone 2 to ensure complete signal amplification. In this embodiment, the power amplifier 3-1 is a vacuum tube audio signal power amplifier, but it can also be a transistor (semiconductor) power amplifier, an integrated circuit (IC) power amplifier, or a hybrid device power amplifier. This utility model is not limited to these. The direct-through circuit 4 uses ordinary wires to simulate long-distance signal transmission without signal amplification (signal attenuation). In addition, an audio signal attenuator can be connected in series in the direct-through circuit 4 to enhance the user's perception of the difference between signal attenuation and amplification.
[0032] The switching component 5 uses a single-pole double-throw switch or a switching socket to switch between signal amplification line 3 and signal direct line 4. This allows analog telephone 1 and analog telephone 2 to communicate via signal amplification line 3 to demonstrate audio signal transmission in signal amplification mode, or via signal direct line 4 to demonstrate audio signal transmission in signal attenuation mode. The switching component 5 also includes a line status indicator 6 to indicate the current working status of the interactive experience device. For example, when analog telephone 1 and analog telephone 2 communicate via amplification line 3, the line status indicator 6 displays green; when communicating via direct line 4, the line status indicator 6 displays red.
[0033] The power supply unit (not shown in the diagram) is electrically connected to analog telephone 1, analog telephone 2, and audio signal power amplifier 3-1, and provides them with operating voltage. For example... Figure 2 The image shown is a second embodiment of the interactive experience device of this utility model. Figure 2 Implementation examples and Figure 1 The first embodiment is largely the same. Figure 2 Implementation examples and Figure 1 The difference in the embodiments is that the interactive component uses a microphone and a speaker, that is, the microphone 1' is used as the transmitter and the speaker 2' is used as the output to simulate the sending and receiving of audio signals by both parties in a call; in addition, a visual display component can be set. In the second embodiment of this utility model, the visual display component uses two rhythm lights 7, which are respectively set at the transmitter end and the output end. The rhythm lights 7 emit light and color changes in accordance with the voice spoken and heard by the user to provide the user with a visual experience; the visual display component can also use an oscilloscope, power meter, etc., for example, the rhythm lights and / or oscilloscope are set at the transmitter end, and the rhythm lights and / or oscilloscope are set at the output end, etc. This utility model is not limited to this.
[0034] Furthermore, based on electronic signal amplification, modifications can be made to this utility model to set up a series of other interactive experience devices, such as changing the interactive components to a voltage supply device and a voltage display device. For example... Figure 3 The diagram shows a third embodiment of the interactive experience device of this invention. In this embodiment, the voltage supply device uses a demonstration battery 1″, and the voltage display device uses a voltmeter 2″. The power amplifier 3-1 in the amplification circuit is replaced with a vacuum tube voltage power amplifier. The demonstration battery 1″ can be made of multiple sets of dry cell batteries. The user can select the number of batteries to connect at the transmitter end, calculate the demonstration voltage, and observe the difference between the voltage reading on the voltmeter 2″ at the output end and the demonstration voltage calculated at the transmitter end by connecting the amplification circuit 3 or the direct circuit 4, thus experiencing the principle of the voltage amplifier. The demonstration battery can also include a voltmeter or other device that can visually display the voltage, allowing the user to intuitively experience the demonstration voltage. The demonstration battery 1″ can also be a DC or AC power supply with a settable voltage; this invention is not limited to these limitations.
[0035] This invention relates to an interactive experience device based on vacuum tube signal amplification. Addressing the problem in electronics education and science exhibitions where existing demonstrations of vacuum tube signal amplification principles often rely on theoretical explanations, circuit diagrams, or static models, lacking interactive scenarios and leading to difficulties in user understanding, this invention provides a simple interactive device that simulates the principle of vacuum tube amplification.

These components work together to simulate signal transmission and amplification. Its innovation lies in its scenario-based interaction, comparative experience, and educational adaptability. It allows users to intuitively experience the difference between signal attenuation and amplification through operation, strengthening their understanding of the amplification function of vacuum tubes. Its simple structure makes it easy to promote and suitable for classrooms, science museums, and other similar settings.
