Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically to a PTT microphone. Background Technology

[0002] Currently, in live performances or recording studios, communication between the front and back stages is mostly done using headsets or handheld microphones. However, existing headsets or handheld microphones remain on after being turned on and need to be manually turned off or controlled by other devices. In practice, this is not only cumbersome to operate, but also often results in noise amplification due to forgetting to turn off the microphone, which can cause performance or recording accidents.

[0003] Chinese Patent No. CN 202353776 U discloses a self-closing microphone, including a microphone body, a microphone head connected to the microphone body, a built-in battery placed inside the microphone body and connected to the microphone head, and a switch connected to the built-in battery. The switch, the built-in battery, and the microphone head form a circuit. The trigger closing button of the switch is located on the outer wall of the microphone body and is connected to the switch body by a spring. One end of the spring is fixed to the inner wall of the switch, and the other end is fixedly connected to the bottom of the trigger closing button. A conductive copper plate is provided at the bottom of the closing button, which contacts a metal plate inside the switch body. When in use, pressing the trigger closing button closes the switch, and releasing the trigger closing button opens the switch and turns off the microphone.

[0004] However, the self-closing microphone provided by the above solution controls the conduction of the microphone battery by pressing a switch. The contact between the copper plate and the metal plate is unstable, causing conduction failure and making it impossible for the microphone to switch between the on and off states stably and reliably.

[0005] Therefore, how to effectively improve the ease of operation of microphones, enabling them to quickly switch between on and off states, and how to improve the stability and reliability of microphone operation to ensure performance and recording quality have become urgent problems to be solved in this field. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PTT switch assembly and microphone that are easy to operate, can quickly switch between open and closed states, and are stable and reliable.

[0007] To achieve the above objectives, the PTT switch assembly provided by this utility model includes a switch bracket and a switch cap, a shock-absorbing ring, a lock-free switch, and a PCB board disposed in the switch bracket.

[0008] The two ends of the latchless switch are respectively connected to the switch cap and the PCB board. The switch cap is configured to drive the latchless switch to move synchronously, so that the latchless switch cooperates with the PCB board to switch between a closed state and an open state.

[0009] The shock-absorbing ring is disposed between the switch cap and the unlocked switch, and is configured to support the switch cap under its own elastic force to maintain the closed state. In the open state, it can also drive the switch cap to reset under its own elastic restoring force and eliminate the vibration and friction generated when the switch cap moves.

[0010] Furthermore, the switch cap includes a pressing plate, and a connecting post for cooperating with the switch bracket is provided on the first surface of the pressing plate.

[0011] Furthermore, the switch bracket is provided with a mounting base, the switch cap and the shock absorber are mounted on the mounting base, and the mounting base is provided with a slot that matches the connecting post.

[0012] Furthermore, a number of anti-slip grooves are distributed on the second surface of the pressing plate.

[0013] Furthermore, the unlocked switch is provided with a switch assembly for cooperating with the switch cap. The switch assembly is axially movable in the unlocked switch and connected to the PCB board.

[0014] Furthermore, the shock-absorbing ring includes a fixed seat for cooperating with the mounting seat and a support seat for cooperating with the switch cap. The support seat is disposed in the middle of the fixed seat and is connected to the fixed seat by elastic connectors disposed around the support seat.

[0015] Furthermore, one end of the elastic connector is connected to the fixed base, the other end is connected to the support base, and an arc-shaped shock-absorbing block protruding outward is formed in the middle.

[0016] Furthermore, a connecting cavity is formed between the two adjacent elastic connectors so that the connecting post of the switch cap can pass through the connecting cavity and engage with the slot on the mounting base.

[0017] To achieve the above objectives, the microphone provided by this utility model includes a microphone head and a grip, wherein the grip is provided with the aforementioned PTT switch assembly.

[0018] Furthermore, the switch cap is distributed on the handle, and in the closed state, the switch cap is flush with the handle.

[0019] The PTT switch assembly and microphone provided by this utility model have a switch cap and a PCB board connected to the two ends of the unlocked switch, respectively. The switch cap can drive the unlocked switch to move synchronously. A shock-absorbing ring is set between the switch cap and the unlocked switch. In the initial state, the shock-absorbing ring can support the switch cap under its own elastic force, so that the unlocked switch can cooperate with the PCB board to be in the closed state and remain in the closed state. At the same time, the switch cap can drive the unlocked switch to move synchronously under the action of external force, so that the unlocked switch can cooperate with the PCB board to switch to the open state. Since the unlocked switch is in contact with the PCB board, the effective conduction of the PCB board can be ensured, so that the open state remains stable. When the external force is removed, the shock-absorbing ring can drive the switch cap to reset under the action of its own elastic restoring force, so as to return to the initial closed state, thereby realizing rapid switching between open and closed states. At the same time, the shock-absorbing ring can simultaneously eliminate the vibration and friction generated by the movement of the switch cap, preventing the noise generated by vibration and friction from being transmitted into the microphone.

[0020] Therefore, the microphone provided by the present invention can turn on when the switch cap is pressed and immediately turn off when the finger is removed from the switch cap, so as not to cause noise interference to recording and performance. In addition, the switch cap is flush with the handle, so as not to cause accidental activation of the switch cap, further ensuring the stability and reliability of the off state.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0029] See Figures 1 to 3 The illustration shows an example of a PTT switch assembly provided by this utility model.

[0030] As shown in the figure, the PTT switch assembly in this example mainly includes a switch bracket 1, a switch cap 2, a shock absorber ring 3, a lockless switch 4, and a PCB board 5, all housed in the switch bracket 1.

[0031] The two ends of the unlocked switch 4 are connected to the switch cap 2 and the PCB board 5 respectively. The switch cap 2 is configured to drive the unlocked switch 4 to move synchronously, so that the unlocked switch 4 and the PCB board 5 can switch between the closed state and the open state, so that the PCB board 5 can be effectively connected and maintain the stability of the open state.

[0032] Furthermore, the shock absorber ring 3 is disposed between the switch cap 2 and the unlocked switch 4, and is configured to support the switch cap 2 under its own elastic force to maintain the closed state. In the open state, it can also drive the switch cap 2 to reset under its own elastic restoring force, and eliminate the vibration friction shock absorber ring generated when the switch cap 2 moves. This makes the PTT switch assembly easy to operate, can quickly switch between open and closed states, and is stable and reliable.

[0033] Combination Figures 1 to 3 The switch cap 2 includes a pressing plate 21. The first surface 211 of the pressing plate 21 is provided with a connecting post 22 for cooperating with the switch bracket 1, so that the switch cap 2 can be set in the switch bracket 1 through the connecting post 22.

[0034] Furthermore, the switch bracket 1 is provided with a mounting base 11, the switch cap 2 and the shock absorber ring 3 are mounted on one side of the mounting base 11, and the unlocked switch 4 and the PCB board 5 are mounted on the other side of the mounting base 11. The switch cap 2, the shock absorber ring 3, the unlocked switch 4 and the PCB board 5 can be connected and cooperated with each other through the mounting base 11.

[0035] Specifically, the mounting base 11 is provided with a slot 12 that matches the connecting post 22, so that the connecting post 22 can be placed in the slot 12 to connect the switch cap 2 to the switch bracket 1. At the same time, when the switch cap 2 moves towards the PCB board under the action of external force, it will drive the connecting post 22 to move towards the PCB board synchronously, so that the connecting post 22 moves axially in the slot 12. The slot 12 can guide and restrict the movement direction of the connecting post 22, ensuring that the switch cap 2 does not deviate during the movement and reset process, thereby ensuring the stable cooperation between the lockless switch 4 and the PCB board 5.

[0036] Furthermore, a number of anti-slip grooves 23 are distributed on the second surface 212 of the pressing plate 21. The anti-slip grooves 23 are preferably configured as arc grooves and are not evenly distributed on the second surface 212 of the pressing plate 21 to increase the friction between the fingers and the pressing plate 21. At the same time, the arc grooves can improve the contact feel between the fingers and the pressing plate 21.

[0037] In conjunction with this, the unlocked switch 4 is provided with a switch assembly 41 for cooperating with the switch cap 2. The switch assembly 41 is configured to move axially in the unlocked switch 4 and is connected to the PCB board 5, so that the first surface 211 of the switch cap abuts against the switch assembly 41. The switch cap 2 can drive the switch assembly 41 to move synchronously, so that the switch assembly 41 cooperates with the PCB board 5 and switches between the closed state and the open state.

[0038] Combination Figure 1 and Figure 2 For example, when the switch cap 2 moves toward the PCB board 5 under the action of external force, the switch cap 2 will drive the switch assembly 41 of the unlocked switch 4 to move toward the PCB board 5 simultaneously, so that the switch assembly 41 and the PCB board 5 come into contact with each other, so that the PTT switch assembly switches from the closed state to the open state.

[0039] Meanwhile, since the lockless switch 4 is in contact with the PCB board 5 as a whole, it can effectively maintain the conductivity of the PCB board 5 to keep it in the open state.

[0040] Conversely, when the switch cap 2 moves away from the PCB board 5 under the action of external force, the switch cap 2 will drive the switch assembly 41 of the unlocked switch 4 to move away from the PCB board 5 in sync, so that the switch assembly 41 and the PCB board 5 no longer abut, so that the PTT switch assembly returns from the open state to the initial closed state.

[0041] In order to enable the switch cap 2 to move stably under the action of external force and to self-reset when the external force is removed, making the PTT switch assembly easy to operate and able to quickly switch between the closed and open states, the shock absorber 3 is set between the switch cap 2 and the unlocked switch 4, so that the shock absorber 3 can cooperate with the switch cap 2 to maintain the stable movement and reset of the switch cap 2.

[0042] Combination Figures 1 to 3 Furthermore, the shock absorber 3 includes a fixed seat 31 for cooperating with the mounting base 11 and a support seat 32 for cooperating with the switch cap 2. The support seat 32 is located in the middle of the fixed seat 31 and is connected to the fixed seat 31 by elastic connectors 33 arranged around the support seat 32, so that the shock absorber 3 abuts against the first surface 211 of the switch cap 2 through the support seat 32 and is mounted on the mounting base 11 through the fixed seat 31.

[0043] Furthermore, two adjacent elastic connectors 33 around the support base 32 form a connecting cavity 34, so that the connecting post 22 of the switch cap 2 can pass through the connecting cavity 34 and cooperate with the slot 12 on the mounting base 11, so that the switch cap 2 and the shock absorber 3 are mutually cooperated and set on the mounting base 11, and the shock absorber 3 is set between the switch cap 2 and the unlocked switch 4, and can cooperate with the switch cap 2 to improve the stability of this PTT switch assembly.

[0044] Specifically, the support base 32 is connected to the fixed base 31 around its perimeter by elastic connectors 33, so that the elastic connectors 33 can cooperate with the support base 32 and the fixed base 31. Under the action of the elastic force of the elastic connectors 33, the switch cap 2 is supported, and the elastic force of the elastic connectors 33 is sufficient to support the switch cap 2, so that the switch assembly 41 of the lockless switch 4 does not contact the PCB board 5, thereby maintaining the closed state.

[0045] Correspondingly, when the switch cap 2, under the action of external force, causes the switch assembly 41 of the unlocked switch 4 to contact the PCB board 5, switching from the closed state to the open state, it generates a force on the support base 31 facing the PCB board 5. At the same time, the elastic connector 33 is synchronously compressed under the action of external force, storing elastic force. When the external force disappears, the elastic connector 33 will release the elastic force, and under its own elastic restoring force, it will drive the switch cap 2 and the switch assembly 41 of the unlocked switch 4 to move synchronously away from the PCB board 5, resetting the switch cap 2, so that the unlocked switch 4 no longer contacts the PCB board 5, restoring from the open state to the closed state. Thus, this PTT switch assembly can conveniently and reliably achieve pressing to open and releasing to reset to close.

[0046] Furthermore, an outwardly protruding arc-shaped shock absorber 35 is formed in the middle region of the elastic connector 33, so that the arc-shaped shock absorber 35 can provide better elastic deformation capability for the elastic connector 33. When the elastic connector 33 is subjected to external force, the arc-shaped shock absorber 35 bends and deforms. This deformation can absorb some energy and convert some energy into the deformation of the arc-shaped shock absorber 35 itself, thereby reducing the vibration transmitted to other components and effectively reducing the noise generated by vibration and friction during the movement of the switch cap 2.

[0047] The shock-absorbing ring 3 formed by this works in conjunction with the switch cap 2 and the guide post 24 to keep the PTT switch assembly in the closed state. In the open state, it can stably drive the switch cap 2 to reset and restore the PTT switch assembly to the closed state. This allows the PTT switch assembly to be turned on by pressing and turned off by releasing, while eliminating the noise generated by the movement and friction of the switch cap 2 during the switching process.

[0048] This constitutes the PTT switch assembly provided by this utility model.

[0049] Combination Figure 4 The present invention also provides a microphone, including a microphone head 6 and a grip 7. The grip 7 is provided with a PTT switch assembly configured as described above, so that the microphone can switch from the off state to the on state when the switch cap 2 is pressed, and can perform sound amplification. When the finger is removed from the switch cap 2, the microphone can immediately return from the on state to the off state and remain off, so as not to cause noise interference to recording and performance.

[0050] Meanwhile, the shock-absorbing ring 3, through the cooperation of the elastic connector 33 and the switch cap 2, can reduce the noise generated by the microphone during the switching process, prevent the noise generated by vibration and friction from entering the microphone head 7, and will not cause noise interference to recording and performance.

[0051] Furthermore, the switch cap 2 is distributed on the handle 7. In the closed state, the switch cap 2 is flush with the handle 7, which will not cause accidental activation of the switch cap 2 and further ensures the stability and reliability of the closed state.

[0052] The following example illustrates the working process of this utility model in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0053] In the initial closed state, the shock absorber 3 supports the switch cap 2 under its own elastic force, so that the switch assembly 41 of the unlocked switch 4 does not contact the PCB board 5, thereby keeping it closed.

[0054] Under the action of external force, the switch cap 2 drives the unlocked switch 4 to move synchronously toward the PCB board 5. The elastic connector 33 of the shock absorber ring 3 will be compressed synchronously under the action of external force to store elastic force. At the same time, the arc-shaped shock absorber block 35 bends and deforms to reduce the vibration transmitted to other components, so as to effectively reduce the noise generated by the vibration and friction of the switch cap 2 during movement.

[0055] The switch assembly 41 of the lockless switch 4 is in contact with the PCB board 5. When switching from the closed state to the open state, it remains in the open state under the action of external force.

[0056] When the external force disappears, the elastic connector 33 of the shock absorber ring 3 releases its elastic force. Under the action of its own elastic restoring force, it drives the switch cap 2 and the switch assembly 41 of the unlocked switch 4 to move synchronously away from the PCB board 5, so that the switch cap 2 is reset and the switch assembly 41 is no longer in contact with the PCB board 5, returning from the open state to the closed state. This enables the PTT switch assembly to conveniently and reliably achieve pressing to open and releasing to reset and close.

[0057] The PTT switch assembly and microphone provided by this utility model, through the cooperation of switch cap 2, shock absorber ring 3, lockless switch 4 and PCB board 5, can realize convenient operation of microphone, quick switching between open and closed states, and stable and reliable operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
