[0003] However, existing microphones on the market generally have significant defects and shortcomings. Their output sensitivity is low, and they are difficult to effectively capture and amplify weak audio signals, resulting in unclear sound reproduction and failing to meet users' needs for high-quality audio communication. Therefore, this utility model provides a reed microphone. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reed-type microphone, comprising a yoke, wherein the yoke has a left chamber and a right chamber, and two coils are provided on the right chamber of the yoke, the two coils being arranged coaxially, and coils are wound on the coils, with a connecting wire between the two coils. A bracket is installed between the inner top and inner bottom surfaces of the right chamber of the yoke, and a rotating shaft is fixedly connected to the outer surface of the bracket. A reed is rotatably provided on the outer wall of the rotating shaft, and the left and right sides of the reed pass through the interior of the two coils.

[0006] Preferably, the yoke has two through holes, and the left and right sides of the tongue spring pass through the inner sides of the two through holes respectively, with the left side of the tongue spring placed in the left cavity of the yoke and the right side of the tongue spring placed in the right side of the yoke.

[0007] Preferably, the bracket is positioned between the two spools, and a contact rod is mounted on the left side of the reed.

[0008] Preferably, a magnet is provided in the left side cavity of the yoke, and the top and bottom surfaces of the magnet are respectively connected to the top and bottom surfaces of the left side cavity of the yoke, and the magnet is placed on the left side of the contact rod.

[0011] Beneficial effects

[0012] This invention provides a reed-type microphone. Compared with the prior art, it has the following advantages:

[0013] 1. This reed-type receiver connects to AC power via terminals. Since the coil is powered by AC, the magnetic field direction on both sides of the reed changes continuously, causing the reed to swing up and down continuously. The reed is connected to the diaphragm, causing the diaphragm to vibrate and produce sound. Because both sides of the reed receive push and pull forces, the working efficiency is higher, theoretically twice that of ordinary electromagnetic receivers, making energy utilization more efficient.

[0014] 2. In this reed-type microphone, due to the repulsion of like poles and the attraction of unlike poles, when the magnetic field generated by the coil is energized and its direction is the same as the magnetic field formed by the magnet and the yoke, they will attract each other, forming a pulling force. On the opposite side, they will repel each other, forming a pushing force. The N pole on the upper part of the yoke and the N pole of the reed repel each other, generating a pushing force, while the S pole on the lower part of the yoke and the N pole of the reed attract each other, forming a pulling force. The right side of the reed is exactly the opposite of the left side, generating an upward and downward pushing action. The reed will swing up and down on both sides around the pivot on the bracket, which not only ensures the stable and efficient vibration of the reed, but also provides a stable and reliable power source for the subsequent linkage with the diaphragm.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides two technical solutions:

[0023] Figures 1-5 The first embodiment is shown: a reed-type microphone includes a yoke 1, which has a left chamber and a right chamber inside. The right chamber of the yoke 1 has two coils 3 arranged coaxially. A coil 31 is wound on the coil 3, and a connecting wire 32 is provided between the two coils 31. A bracket 2 is installed between the inner top surface and the inner bottom surface of the right chamber of the yoke 1. A rotating shaft 21 is fixedly connected to the outer surface of the bracket 2. A reed 23 is rotatably provided on the outer wall of the rotating shaft 21. The left and right sides of the reed 23 pass through the interior of the two coils 3.

[0024] Two through holes 11 are provided on the yoke 1. The tongue spring 23 passes through the inside of the two through holes 11 on the left and right sides respectively. The left side of the tongue spring 23 is placed in the left cavity of the yoke 1, and the right side of the tongue spring 23 is placed in the right side of the yoke 1.

[0025] The bracket 2 is positioned between the two reels 3, and the contact rod 24 is installed on the left side of the reed 23.

[0026] A magnet 4 is provided in the left chamber of the yoke 1, and the top and bottom surfaces of the magnet 4 are connected to the top and bottom surfaces of the left chamber of the yoke 1, respectively. The magnet 4 is located on the left side of the contact rod 24.

[0027] The bottom of the yoke 1 is provided with a diaphragm 5, and the top surface of the diaphragm 5 is provided with a sound guide rod 51. The sound guide rod 51 passes through the bottom surface of the yoke 1 and extends into the left side cavity of the yoke 1. The sound guide rod 51 is connected to the contact rod 24.

[0028] Specifically, when alternating current is connected through terminal 34, causing alternating current to flow through coil 31, an alternating magnetic field is generated around coil 31 according to Ampere's law. Due to the magnetic permeability of yoke 1, this alternating magnetic field is concentrated inside yoke 1, and reed 23 is precisely in this alternating magnetic field environment. According to Lenz's law, reed 23 is subjected to a constantly changing Ampere force, and thus, under the constraint of the rotating shaft 21 of bracket 2, it continuously swings up and down. Reed 23 is connected to diaphragm 5 through sound guide rod 51, and diaphragm 5 will vibrate accordingly, thereby causing changes in the density of the surrounding air, ultimately producing sound, thus achieving efficient conversion of electrical signals to sound signals.

[0029] Figures 1-5 The second embodiment is shown, and its main difference from the first embodiment is:

[0030] Multiple fixing rods 35 are installed on the side of the coil 3. The fixing rods 35 are connected to the inner wall of the right cavity of the yoke 1. Both coils 31 are connected to external wires 33, and the external wires 33 pass through the inside of the yoke 1 and extend outward. A terminal block 34 is connected between the ends of the two external wires 33.

[0031] Specifically, the fixing rod 35 firmly connects the coil 3 to the inner wall of the right side cavity of the yoke 1, and the connection is provided with an insulating layer. The external wiring 33 connected to the two coils 31 and the terminal block 34 connected between the ends provide a convenient and reliable way for current to enter, so that external AC power can be stably input into the coils 31, providing a continuous and stable energy source for the electromagnetic drive system of the entire transmitter and receiver, ensuring that the transmitter and receiver can work normally and efficiently and realize the electroacoustic conversion function.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, when alternating current is connected through terminal 34, causing alternating current to flow through coil 31, an alternating magnetic field is generated around coil 31 according to Ampere's law. Due to the magnetic permeability of yoke 1, this alternating magnetic field is concentrated inside yoke 1, and reed 23 is precisely in this alternating magnetic field environment. According to Lenz's law, reed 23 is subjected to a constantly changing Ampere force, and thus, under the constraint of the rotating shaft 21 of bracket 2, it continuously swings up and down. Reed 23 is connected to diaphragm 5 through sound guide rod 51, and diaphragm 5 vibrates accordingly, thereby causing changes in the density of the surrounding air and ultimately producing sound, achieving efficient conversion of electrical signals to sound signals. In this process, because reed 23 is subjected to alternating magnetic fields on both sides, the alternating pushing and pulling forces make the force on reed 23 more uniform. Compared with traditional electromagnetic receivers, it can make fuller use of electromagnetic force to do work during energy conversion. Theoretically, the work efficiency can reach about twice that of ordinary electromagnetic receivers, making energy utilization more efficient.

[0034] Meanwhile, considering the inherent magnetic field formed by the magnet 4 and the yoke 1, when the magnetic field generated by the coil 31 is energized and aligns with it, according to the electromagnetic principle of like poles repelling and unlike poles attracting, on the side with the same magnetic field direction, such as the N pole on the upper part of the yoke 1 and the N pole of the reed 23, they will repel each other, forming a pushing force; while on the side with the opposite magnetic field direction, such as the S pole on the lower part of the yoke 1 and the N pole of the reed 23, they will attract each other, generating a pulling force. For the right side of the reed 23, the same principle generates a force opposite to that on the left, causing the reed 23 to swing up and down in a coordinated manner around the pivot 21 on the support 2. Through this precise magnetic field interaction, not only is stable and efficient vibration of the reed 23 ensured, but a stable and reliable power source is also provided for subsequent linkage with the diaphragm 5.
