Description

Technical Field

[0001] This utility model relates to the field of electret condenser microphone technology, and in particular to an electret condenser microphone with a timing speaking function. Background Technology

[0002] Electret condenser microphones are widely used in communication, recording, and public address systems for sound-to-electrical conversion. They utilize the permanent charge properties of electret materials to convert sound signals into electrical signals, offering advantages such as small size, high sensitivity, and low cost.

[0003] Chinese invention patent application CN209046882U discloses an electret condenser microphone and microphone. The patent includes a backplate, a gasket, and a diaphragm. The backplate and diaphragm constitute a variable capacitor. The gasket is located between the backplate and the diaphragm and is tightly attached to the diaphragm. The gasket has multiple slots to provide vibration space for the diaphragm. By forming multiple slots on the gasket, the diaphragm has multiple different vibration regions when receiving sound vibrations. Adjusting the size of the slots according to actual needs can change the diaphragm amplitude corresponding to different vibration regions, thereby creating different potential changes between the backplate position and the diaphragm position corresponding to different vibration regions. This is equivalent to multiple variable capacitors connected in parallel, thereby increasing the frequency range of received sound and controlling the overall frequency response curve.

[0004] In existing technology, the power supply battery of electret condenser microphones is separately located inside the microphone, meaning it does not include a charging device. Conventional microphones are constantly powered by the battery, whether the microphone is speaking or not. This leads to rapid power consumption, which is detrimental to the microphone's battery life and the battery's lifespan. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electret condenser microphone with a timing function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electret condenser microphone with timing function includes an electret condenser microphone and further includes:

[0008] The timing and speaking component includes a base plate, a timer on one side of the base plate, a sound sensor on one side of the timer, a controller on one side of the sound sensor, an electromagnetic rail on one side of the controller, a guide rod slidingly disposed inside the electromagnetic rail, a gate base on the other side of the electromagnetic rail, and a battery on the other side of the base plate.

[0009] The timer, acoustic sensor, and electromagnetic rail are connected by a junction box.

[0010] A further technical solution involves installing wires inside the junction box, which connect the timer, the acoustic sensor, and the electromagnetic rail.

[0011] A further technical solution involves connecting one side of the battery's output terminal to one side of the gate base.

[0012] A further technical solution involves installing copper sheets inside the gate base and guide grooves inside the electromagnetic guide rail.

[0013] A further technical solution involves sliding the guide rod inside the guide groove, with the guide rod made of a conductive material.

[0014] A further technical solution involves a display screen on the surface of the timer, and the timer itself is an electronic timing device.

[0015] A further technical solution involves an outer cover connecting the electret condenser microphone and the timing speech component. The outer cover has rounded corners around its perimeter and a hole in the middle. A wire is provided on one side of the controller and connected to one side of the electret condenser microphone.

[0016] Compared with the prior art, this utility model provides an electret condenser microphone with a timing function, which has the following advantages:

[0017] By incorporating a timing component, we've installed a timing device based on a sound sensor and an electronic timer between the traditional electret condenser microphone and the battery. Its main function is to time the user's speech and control battery power. Once the speaking time is up, it controls an electromagnetic switch to cut off power, thus stopping battery supply. This device avoids the problem of rapid power consumption caused by continuous battery power while also ensuring long battery life. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figure 1 - Figure 4 An electret condenser microphone with timing function is disclosed, comprising an electret condenser microphone 1. The electret condenser microphone is a widely used sound-to-electric conversion device in communication, recording, and sound reinforcement systems. It utilizes the permanent charge characteristics of electret materials to convert sound signals into electrical signals, offering advantages such as small size, high sensitivity, and low cost.

[0025] Also includes:

[0026] The timing and speaking component 2 includes a base plate 3, which is the part where the component is electrically connected and mounted. A timer 4 is disposed on one side of the base plate 3, used to indirectly control the timer 4 for timing via a sound sensor 5. The sound sensor 5 is also disposed on one side of the timer 4, collecting the speaker's speaking signal. A controller 6 is disposed on one side of the sound sensor 5, used to indirectly control the movement of the electromagnetic rail 7. The electromagnetic rail 7 is disposed on one side of the controller 6, controlling a guide rod 8 to slide within a guide groove 16. When the guide rod 8 slides to the surface of the copper sheet 15 inside the gate base 9, the circuit is connected. The guide rod 8 is slidably disposed inside the electromagnetic rail 7. The gate base 9 is disposed on the other side of the electromagnetic rail 7, and a battery 12 is disposed on the other side of the base plate 3, serving as the power supply for this device.

[0027] The timer 4, the acoustic sensor 5, and the electromagnetic rail 7 are connected by a junction box 10, thus realizing the circuit path.

[0028] The electret condenser microphone with timing function has wires installed inside the junction box 10, which connect the timer 4, the acoustic sensor 5, and the electromagnetic rail 7 respectively.

[0029] The electret condenser microphone with timing function has one side of the output terminal of the battery 12 connected to one side of the gate base 9 to achieve the power supply effect of the battery 12.

[0030] The electret condenser microphone with timing function has a copper sheet 15 inside the gate base 9, which is the part where the guide rod 8 is connected and attached.

[0031] The electromagnetic rail 7 has a guide groove 16 inside.

[0032] The electret condenser microphone with timing function has a guide rod 8 slidably installed inside the guide groove 16. The guide rod 8 is made of conductive material and is used to replace wires to achieve the circuit connection effect.

[0033] The electret condenser microphone with timing function has a display 18 on its surface, which displays the timing time. The timer 4 is an electronic timing device, which facilitates the implementation of automation.

[0034] An electret condenser microphone with a timing function is described above. The electret condenser microphone 1 and the timing component 2 are connected by an outer cover 13, which serves as a connecting component. The outer cover 13 has rounded corners 17 around its perimeter, and a hole 14 is provided in the middle of the outer cover 13. A wire 11 inside the hole 14 connects the microphone and the timing component 2. A wire 11 is provided on one side of the controller 6, and the wire 11 is connected to one side of the electret condenser microphone 1.

[0035] Working principle:

[0036] In the actual design process of this utility model, to avoid the following defects existing in the prior art: "In the prior art, the power supply battery of an electret condenser microphone is separately located inside the microphone, that is, it does not contain a charging device. In a conventional microphone, the battery always supplies power, whether the microphone is speaking or not, which will cause the microphone to consume power too quickly, which is detrimental to the microphone's battery life and the battery's lifespan." Therefore, a timing speaking component 2 is specifically proposed:

[0037] The timing speech component 2 is mainly installed between the electret condenser microphone 1 and the battery 12 to control the power supply effect of the battery 12 in real time, avoiding damage caused by prolonged battery drain. In use, a preset timing period is assigned to the timer 4. During the speaker's speech, the acoustic sensor 5 receives sound information in real time and controls the timing period through the timer 4. The control structure is located inside the controller 6. Once the timing period is up, the controller 6 controls the electromagnetic rail 7 to run, and controls the guide rod 8 to slide inside the electromagnetic rail 7, thereby causing the guide rod 8 to disengage from the copper sheet 15 inside the gate base 9. Since the copper sheet 15 is directly connected to the battery 12, this directly causes the microphone to lose power, achieving the effect of timing power supply.
