Description

Technical Field

[0001] This utility model belongs to the field of walkie-talkie technology, and in particular relates to a novel hand microphone. Background Technology

[0002] A handheld microphone is a type of walkie-talkie. As a two-way mobile communication tool, it can make calls without network support. It is suitable for relatively fixed and frequent communication situations and has become an important tool for short-distance communication and mobile dispatch and command.

[0003] The existing handheld microphones can be used directly by hand or worn on the waist, shoulder, or other positions by attaching a back clip, which is very convenient. However, in actual use, it has been found that when the handheld microphone is worn with a back clip, it is difficult for the user to adjust the orientation and position of the microphone, which causes the microphone to be unable to get close to the sound source and receive sound normally, affecting the call quality.

[0004] Therefore, it is necessary to design a new type of hand microphone to solve this problem. Utility Model Content

[0039] See appendix Figure 1 -Appendix Figure 8 A novel hand microphone includes a hand microphone body 1, a linkage plate 2, and a back clip 3. The hand microphone body 1 is equipped with a microphone 101 for receiving sound and a speaker 102 for playing sound. The linkage plate 2 is slidably disposed on the back side of the hand microphone body 1 and has sliding damping so that the linkage plate 2 can be stopped and fixed after sliding. The back clip 3 includes a pressure rod 31, a clamping rod 32, and a coil spring 33. The pressure rod 31 is rotatably mounted on the linkage plate 2 and has rotational damping, and the head end of the pressure rod 31 is rotatably connected to the head end of the clamping rod 32. The coil spring 33 is installed at the rotatable connection between the pressure rod 31 and the clamping rod 32 and drives the tail end of the clamping rod 32 to approach the tail end of the pressure rod 31. Pressing the head end of the clamping rod 32 can drive the tail end of the clamping rod 32 away from the tail end of the pressure rod 31.

[0040] Specifically, under normal circumstances, users can directly hold the hand microphone unit 1 for use;

[0041] When it is necessary to wear the hand microphone 1, press the first end of the clamping rod 32 to drive the tail end of the clamping rod 32 away from the tail end of the pressure rod 31 to form a clamping opening for holding objects. At this time, the coil spring 33 deforms and stores energy. After the clamping opening is wrapped around the belt or clothing, release the first end of the clamping rod 32. The coil spring 33 releases energy and restores its function, driving the tail end of the clamping rod 32 to come closer to the tail end of the pressure rod 31, so that the clamping opening is narrowed and clamps the belt or clothing. Then the hand microphone 1 can be worn on the waist or shoulder.

[0042] After the hand microphone 1 is worn, the user can slide the hand microphone 1 to adjust its position. Since there is sliding damping between the hand microphone 1 and the linkage plate 2, when the hand microphone 1 is slid to the desired position, releasing the hand microphone 1 will stop it in the current position. Similarly, the user can also rotate the hand microphone 1 to adjust its orientation. Since there is rotational damping between the linkage plate 2 and the pressure rod 31, after the hand microphone 1 is rotated to the desired orientation, releasing the hand microphone 1 will keep it in the current orientation. After the hand microphone 1 is adjusted in position and / or orientation, its built-in microphone 101 can be brought close to the sound source to receive sound normally.

[0043] In summary, by adding a linkage plate 2 between the hand microphone body 1 and the back clip 3, this utility model allows the hand microphone body 1 to adjust its orientation and position according to needs after being worn, thereby ensuring that the microphone 101 built into the hand microphone body 1 can be close to the sound source and receive sound normally, thus ensuring call quality; at the same time, this structural design can also increase the fun of operation and improve the overall user experience.

[0044] See appendix Figure 11 The tail ends of the clamping rod 32 and the pressure rod 31 are provided with interlocking teeth 30 so that they can more stably grip the clothes or belt.

[0045] See appendix Figure 4 -Appendix Figure 6 and attached Figure 10 The hand microphone body 1 includes a main shell 11, a back shell 12, and a control unit 13; the main shell 11 and the back shell 12 are assembled together and enclose a cavity 10 for mounting the control unit 13; the microphone 101 and the speaker 102 are both installed inside the main shell 11 and connected to the outside, and the control unit 13 is electrically connected to the microphone 101 and the speaker 102; the linkage plate 2 is slidably disposed on the back shell 12 and has sliding damping.

[0046] Specifically, the design of the main shell 11 and the back shell 12 facilitates the assembly, disassembly and maintenance of components such as the control unit 13, the speaker 102 and the microphone 101. The main shell 11, as the front part of the hand microphone body 1, is used to install the speaker 102 and the microphone 101, so that the speaker 102 and the microphone 101 can face away from the body and towards the outside. The back shell 12, as the rear part of the hand microphone body 1, is used to install the linkage plate 2, so that the back clip 3 can clip the clothes.

[0047] In use, the control unit 13 receives the sound signal from the microphone 101 and sends the sound signal to other hand microphones. At the same time, the control unit 13 can also receive the sound signals sent by other hand microphones and play them through the speaker 102, thereby realizing intercom communication between two hand microphones.

[0048] See appendix Figure 4 -Appendix Figure 6 and attached Figure 10 The control unit 13 includes a circuit board 131, a battery 132, and control buttons 133. Multiple control buttons 133 are provided and are respectively installed on the side wall of the main housing 11. The circuit board 131 and the battery 132 are both installed in the receiving cavity 10, and the circuit board 131 is electrically connected to the microphone 101, the speaker 102, the battery 132, and the multiple control buttons 133.

[0049] Specifically, the battery 132 is used to power the circuit board 131. The user can control the circuit board 131 through the control button 133, thereby making full use of the microphone 101 and the speaker 102 to realize intercom communication. Since the relevant structure and technology belong to the prior art and are relatively conventional in the field, the specific working principle of this utility model will not be described in detail.

[0050] See appendix Figure 2 -Appendix Figure 10 The outer wall of the back shell 12 is provided with a sliding column 121, and the linkage plate 2 is provided with a sliding groove 21 that slides with the sliding column 121. The linkage plate 2 is also provided with a fastening bolt 20. The tail end of the fastening bolt 20 passes through the sliding groove 21 and is threadedly connected to the sliding column 121. The head end of the fastening bolt 20 can abut against the linkage plate 2 as the fastening bolt 20 rotates, so that there is sliding damping between the linkage plate 2 and the back shell 12, or the linkage plate 2 can be directly locked onto the back shell 12.

[0051] Specifically, during installation, first place the linkage plate 2 on the outer wall of the back shell 12 and insert the sliding column 121 into the sliding groove 21. Then, connect the sliding column 121 through the threaded fastener 20 and rotate the fastener 20 until the head end of the fastener 20 abuts against the linkage plate 2, so that friction is generated between the linkage plate 2 and the back shell 12 to achieve sliding damping.

[0052] Therefore, the sliding damping between the linkage plate 2 and the back shell 12 is determined by the tightness of the fastening bolt 20. Under normal circumstances, when the fastening bolt 20 is not fully tightened, the user can apply appropriate force to the hand microphone body 1 to overcome the sliding damping and slide the hand microphone body 1 normally, making it convenient for the user to adjust the position of the hand microphone body 1. When the fastening bolt 20 is fully tightened, the linkage plate 2 can be completely locked and fixed on the back shell 12, preventing the hand microphone body 1 from sliding and becoming misaligned when the user moves it, thus ensuring the stability of use.

[0053] It should be noted that, in addition to the above structure, a sliding cavity (not shown in the figure) can also be designed directly on the back shell 12, and the linkage plate 2 can be placed in the sliding cavity and designed to be an interference fit. Alternatively, a sliding fit with sliding damping can be used between the linkage plate 2 and the back shell 12. In fact, there are various structures for designing the back shell 12 and the linkage plate 2 to be a sliding fit with sliding damping. This utility model will not list them all, but it does not limit them.

[0054] See appendix Figure 2 and attached Figure 8 -Appendix Figure 11 Furthermore, the linkage plate 2 is also provided with a hidden groove 22 that connects to the sliding groove 21. When the head end of the fastening bolt 20 abuts against the linkage plate 2, it is placed in the hidden groove 22 to improve the overall aesthetics and prevent the head end of the fastening bolt 20 from obstructing the rotation of the pressure rod 31.

[0055] See appendix Figure 2 and attached Figure 8 -Appendix Figure 10 The outer wall of the back shell 12 is provided with a cavity 124 that encloses the linkage plate 2. After the linkage plate 2 slides, it can abut against the side wall of the cavity 124. This design can not only restrict the linkage plate 2, but also make it convenient for users to observe the sliding position of the linkage plate 2, while improving the overall aesthetics.

[0056] See appendix Figure 4 -Appendix Figure 11 The linkage plate 2 has multiple recesses 23 arranged in a circular array, and the pressure rod 31 has multiple protrusions 311 arranged in a circular array. The multiple protrusions 311 can be engaged with the multiple recesses 23 one by one as the pressure rod 31 rotates, so that there is rotational damping between the pressure rod 31 and the linkage plate 2.

[0057] Specifically, under normal circumstances, multiple protrusions 311 engage with multiple recesses 23 one by one to provide damping to limit the rotation of the pressure rod 31; when the user forcefully rotates the hand microphone body 1 and causes the linkage plate 2 to overcome the resistance, multiple protrusions 311 simultaneously disengage from the current recess 23 and move to the next recess 23 until multiple protrusions 311 simultaneously engage with multiple recesses 23 one by one, at which point the hand microphone body 1 stops and maintains its current orientation.

[0058] Furthermore, the pressure bar 31 can be made of an elastic metal material so that the multiple protrusions 311 have the ability to deform and recover. This design facilitates the deformation of the protrusions 311 to disengage from the recess 23 and to recover the engagement recess 23.

[0059] It should be noted that, in addition to the above structure, other structures can also be used to enable rotational damping between the linkage plate 2 and the pressure rod 31. Since there are various related structures, this utility model does not limit this one.

[0060] See appendix Figure 5 -Appendix Figure 8 The protrusion 311 has a hemispherical design. This design can reduce the friction between the protrusion 311 and the side wall of the linkage plate 2, making it easier for the protrusion 311 to disengage from the current recess 23 and engage with the next recess 23, further improving the stability of use.

[0061] See appendix Figure 4 -Appendix Figure 11 The present invention also includes an adjustment component 4, which includes a screw sleeve 41 and an adjustment bolt 42; a guide groove 122 is provided on the inner wall of the back shell 12, and a movable groove 123 is provided on the outer wall of the back shell 12 to connect with the guide groove 122, both the guide groove 122 and the movable groove 123 extending along the sliding direction of the linkage plate 2; a first rotating hole 312 is provided on the pressure rod 31, and a second rotating hole 24 is provided on the linkage plate 2; the tail end of the adjustment bolt 42 penetrates into the movable groove 123, and the head end of the adjustment bolt 42... It can be slidably placed in the guide groove 122; the tail end of the screw sleeve 41 can rotatably pass through the first rotating hole 312 and the second rotating hole 24 into the movable groove 123, and the tail end of the screw sleeve 41 is threadedly connected to the adjusting bolt 42. The head end of the screw sleeve 41 is provided with a dial 43 with a diameter larger than the first rotating hole 312. The dial 43 can abut against or disengage from the pressure rod 31 as the screw sleeve 41 rotates, so that there is rotational damping between the pressure rod 31 and the linkage plate 2, or the pressure rod 31 can be directly locked onto the linkage plate 2.

[0062] Specifically, under normal circumstances, multiple protrusions 311 engage with multiple recesses 23 one-to-one, and there is a certain gap between the dial wheel 43 and the pressure rod 31, so that the multiple protrusions 311 can easily disengage from the corresponding recesses 23, making it convenient for the user to rotate the linkage plate 2. When the user rotates the dial wheel 43 to reduce the gap, the multiple protrusions 311 gradually become more difficult to disengage from the corresponding recesses 23, thereby increasing the rotational damping between the linkage plate 2 and the pressure rod 31. When the screw sleeve 41 and the adjusting bolt 42 are fully tightened, the dial wheel 43 presses against the pressure rod 31, locking the pressure rod 31 onto the linkage plate 2, so that the user cannot rotate the hand microphone body 1.

[0063] On the other hand, when the user needs to adjust the sliding position of the hand microphone body 1, the screw sleeve 41 needs to be loosened to ensure that the adjusting bolt 42 can move along the guide groove 122 as the linkage plate 2 slides. After the position of the hand microphone body 1 is adjusted, the screw sleeve 41 is tightened so that the adjusting bolt 42 stops in the guide groove 122.

[0064] Therefore, the above structural design not only avoids the adjusting bolt 42 from obstructing the sliding of the linkage plate 2, but also allows the user to adjust the rotational damping between the linkage plate 2 and the pressure rod 31, facilitating the rotation of the hand microphone body 1.

[0065] See appendix Figure 4 -Appendix Figure 11The adjusting assembly 4 also includes a spring 44, which is located in the movable groove 123 and sleeved on the tail end of the adjusting bolt 42. The two ends of the spring 44 abut against the bottom wall of the movable groove 123 and the bottom of the screw sleeve 41, respectively.

[0066] Specifically, when the screw sleeve 41 is not connected to the adjusting bolt 42, the spring 44 is in an initial state without energy storage; when the screw sleeve 41 is connected to the adjusting bolt 42, the spring 44 deforms and stores energy to continuously apply pressure to the screw sleeve 41 and the adjusting bolt 42, preventing the adjusting bolt 42 from moving down and dislodging from the guide groove 122; therefore, the design of the spring 44 can effectively reduce the shaking of the adjusting bolt 42 and further improve the operating experience.

[0067] See appendix Figure 2 The dial 43 has a circumferential sidewall that protrudes from both sides of the pressure bar 31, and the circumferential sidewall of the dial 43 is provided with anti-slip texture 430. The protrusion of the dial 43 from both sides of the pressure bar 31 can prevent the pressure bar 31 from obstructing the user's finger movement. With this design, when the microphone body 1 is worn, the user can directly rotate the dial 43 with their fingers. The anti-slip texture 430 design can increase the friction between the fingers and the dial 43, making it easier for the user to drive the dial 43 to rotate.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
