A housing of a transmitter and a transmitter

Abstract

This invention describes a transmitter housing and transmitter. The transmitter housing includes: an outer shell having an inner cavity and a mounting opening communicating with the inner cavity; the outer shell including a first enclosure portion and a second enclosure portion surrounding the mounting opening; and a cover plate covering the mounting opening, the cover plate including a first abutting portion and a second abutting portion arranged in a circumferential manner. The first enclosure portion protrudes towards the cover plate relative to the second enclosure portion, the first abutting portion abuts against the first enclosure portion, and the second abutting portion abuts against the second enclosure portion. This creates a tortuous sealing path at the mounting opening of the outer shell, effectively extending the water penetration path. When the transmitter falls into water or is exposed to high-pressure water, the multi-stage abutting structure can disperse and withstand external water pressure impacts, thereby significantly improving sealing stability and waterproof durability in deep water or high-pressure spray environments.

Description

Technical Field

[0001] This invention relates to the field of audio equipment technology, and more particularly to a transmitter housing and transmitter. Background Technology

[0002] The transmitter of a wireless microphone is used to pick up sound and is usually worn in places such as the user's collar. The transmitter can send audio signals to a paired receiver via radio waves.

[0003] In outdoor recording scenarios such as action filming, transmitters may encounter splashes, heavy rain, or even falling into water. Water ingress can cause signal interruptions or equipment malfunctions, affecting the filming process. Therefore, existing transmitters typically incorporate waterproof gaskets at connection seams to enhance protection. However, when a transmitter falls into water, these measures are insufficient to withstand sustained water pressure, and the sealing reliability is inadequate under deep water pressure, leaving a still relatively high risk of leakage. Summary of the Invention

[0016] Optionally, the transmitter also includes absorbent cotton, which is disposed between the waterproof mesh and the microphone core.

[0017] Optionally, the waterproof mesh is a nano waterproof mesh.

[0018] Optionally, the transmitter further includes: a PCB board disposed within the housing; an antenna bracket connected to the housing, the antenna bracket being located between the housing and the PCB board; an antenna laser-formed onto the antenna bracket; and a connecting terminal fixedly connected to the side of the antenna bracket facing the PCB board, the connecting terminal being electrically connected to the antenna, and the connecting terminal being soldered to the PCB board.

[0019] Optionally, the transmitter includes a PCB board, a connector, and pins. The PCB board includes a main board and a daughter board. The main board is disposed within the housing and has a first guide path. The daughter board is perpendicular to the main board, and an end of the main board abuts against the side of the daughter board.

It is understood that the first enclosure portion and the second enclosure portion can form a stepped structure. Because the first abutting portion abuts against the first enclosure portion and the second abutting portion abuts against the second enclosure portion respectively, a tortuous sealing path can be formed at the mounting port of the outer shell, thereby effectively extending the water penetration path and reducing the risk of liquid directly intruding into the inner cavity. When the transmitter falls into water or is in a high-pressure water environment, the multi-stage clamping structure can disperse and withstand the impact of external water pressure, avoiding pressure concentration on a single sealing interface, thereby significantly improving the sealing stability and waterproof durability in deep water or high-pressure spray environments.

[0047] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0048] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0049] Reference Figures 1 to 4 This application provides a transmitter housing, which includes an outer shell 1 and a cover plate 2. The outer shell 1 has an inner cavity and a mounting port communicating with the inner cavity. The outer shell 1 includes a first enclosure portion 11 and a second enclosure portion 12 surrounding the mounting port, and the first enclosure portion 11 is located at the outer edge. The cover plate 2 covers the mounting port and includes a first abutting portion 21 and a second abutting portion 22 arranged in a surrounding manner. The first enclosure portion 11 protrudes towards the cover plate 2 relative to the second enclosure portion 12, the first abutting portion 21 abuts against the first enclosure portion 11, and the second abutting portion 22 abuts against the second enclosure portion 12.

[0050] According to the above structure, in the housing of the transmitter provided in this application, the first enclosure 11 and the second enclosure 12 can form a stepped structure. Since the first abutting part 21 abuts against the first enclosure 11 and the second abutting part 22 abuts against the second enclosure 12 respectively, a tortuous sealing path can be formed at the mounting opening of the outer shell 1, thereby effectively extending the water penetration path and reducing the risk of liquid directly intruding into the inner cavity. When the transmitter falls into water or is in a high-pressure water environment, the multi-stage abutting structure can disperse and withstand the impact of external water pressure, avoiding pressure concentration on a single sealing interface, thereby significantly improving the sealing stability and waterproof durability in deep water or high-pressure spray environments.

[0051] Reference Figure 2 and Figure 3 In some embodiments, a groove 13 is provided between the first enclosure 11 and the second enclosure 12. The groove 13 is recessed in the direction away from the cover plate 2, and a sealing element is provided in the groove 13. Thus, the sealing element further improves the waterproof performance of the housing, enabling the transmitter to maintain good sealing performance even in deep water pressure environments, allowing the transmitter to stably achieve IPX7 or higher waterproof performance.

[0052] In some embodiments, the sealant is a solid adhesive filled inside the groove 13. The solid adhesive fills the groove 13 in a liquid state, and after curing, it forms a sealant that fits snugly against the groove 13. Specifically, during installation, the operator fills the groove 13 with adhesive and then closes the cover plate 2. After the adhesive dries, it forms a solid adhesive strip that fits snugly against the groove 13 and the gaps. It is understood that the cured adhesive in its liquid state has fluidity, which allows it to fully wet and fill the groove 13 and the surrounding tiny gaps. When the cover plate 2 is closed, the adhesive can further diffuse under pressure into the tiny gaps between the first abutment 21 and the first enclosure 11, and between the second abutment 22 and the second enclosure 12. After curing, the adhesive forms an integrated sealing layer that fits perfectly against the structure, further sealing the leakage path.

[0053] In some examples, the seal may also be a rubber sealing strip.

[0054] In some embodiments, the groove 13 is arranged around the mounting opening. Thus, the seal can also be arranged around the mounting opening, forming a continuously closed sealing ring. This sealing ring forms a seamless waterproof barrier, effectively blocking the path of water penetration and significantly improving waterproof performance.

[0055] This application also provides a transmitter that includes the housing of the transmitter as described above.

[0056] Typically, a small gap is left between the transmitter's button 3 and the housing to allow the button 3 to be pressed smoothly. However, these small gaps also make the transmitter susceptible to water ingress.

[0057] Reference Figure 5 In some embodiments, the transmitter includes a trigger element 5, a waterproof component 4, and a button 3. The trigger element 5 and the waterproof component 4 are located in the inner cavity, and the waterproof component 4 is elastic. The outer shell 1 has an opening 14, and the button 3 extends into the inner cavity from the outside through the opening 14. The waterproof component 4 is located between the trigger element 5 and the button 3, and covers the opening 14. When the button 3 is pressed, the button 3, the waterproof component 4, and the trigger element 5 abut against each other in sequence. It is understood that the waterproof component 4 is elastic. When the button 3 is pressed, the end of the button 3 will press against the waterproof component 4. At this time, the waterproof component 4 deforms and presses the trigger element 5 to complete the on / off or adjustment function of the button 3. Thus, the waterproof component 4 can seal the opening 14, preventing external water from entering the inner cavity through the opening 14, without affecting the pressing function of the button 3.

[0058] In some embodiments, the waterproof component 4 can be made of silicone or rubber. Both rubber and silicone possess excellent elasticity and flexibility, allowing for stable deformation when the button 3 is pressed and rapid rebound after release. Furthermore, they can tightly fit the edge of the opening 14, forming an effective seal that prevents external contaminants such as water and dust from entering the housing, significantly improving the device's waterproof and dustproof rating.

[0059] In some embodiments, the transmitter includes multiple buttons 3 and multiple trigger elements 5. The housing 1 has multiple spaced openings 14, with each button 3 corresponding to one of the openings 14. The waterproof component 4 includes a plate 41 and multiple guide portions 42. The guide portions 42 are connected to the plate 41, protruding from the surface of the plate 41, and the plate 41 is located in the inner cavity. The guide portions 42 are located within the openings 14. The multiple guide portions 42 are spaced apart, and each guide portion 42 corresponds to one of the multiple openings 14. In this embodiment, the multiple buttons 3 and multiple trigger elements 5 are also spaced apart and correspond one-to-one. When one of the buttons 3 is pressed, the corresponding area of ​​the waterproof component 4 will deform to press the corresponding trigger element 5, but other trigger elements 5 will not be pressed in conjunction. Since the guide portion 42 is located within the opening 14, the opening 14 can limit the movement of the guide portion 42, restricting it to only move along the axis of the opening 14 when pressed by the button 3, and also preventing the entire waterproof component 4 from shifting. Furthermore, the end of button 3 abuts against the guide, which improves the accuracy of pressing and ensures that button 3 can ultimately press the corresponding trigger element 5. Specifically, the transmitter's multiple buttons 3 can correspond to multiple different functions, such as powering on / off and initiating Bluetooth connection.

[0060] Reference Figure 7 In some embodiments, the guide portion 42 is provided with a receiving groove 43, the cross-section of which is not circular; the button 3 includes a transmission portion 31, which is located within the receiving groove 43, and the outer contour of the transmission portion 31 matches the inner contour of the receiving groove 43. Thus, the receiving groove 43 can limit the position of the button 3, ensuring that the end of the button 3 is always pressed in a preset position, avoiding tilting or offset, thereby further improving the accuracy of button 3 pressing. Specifically, the cross-section of the receiving groove 43 can be square, elliptical, triangular, or irregularly shaped, thereby preventing the button 3 from rotating within the receiving groove 43, limiting the button 3 to only pressing motion, and improving the accuracy of button 3 pressing.

[0061] In some embodiments, the area of ​​the waterproof component 4 is larger than the area of ​​the opening 14. Therefore, the waterproof component 4 can completely cover the opening 14, preventing water from entering more effectively. Specifically, the plate portion 41 can partially cover the opening 14, with the remaining portion located on the inner wall of the cavity, and the edge area of ​​the plate portion 41 can also be adhered to the inner wall of the cavity using waterproof adhesive.

[0062] Reference Figures 5 to 7 In some embodiments, the transmitter further includes a battery 6, which is fixed to the housing 1 and / or cover 2, and is located at the end of the trigger element 5 opposite to the button 3. When the button 3 is pressed, the end of the trigger element 5 opposite to the button 3 abuts against the outer wall of the battery 6. Accordingly, the battery 6, as a stable component within the housing, provides reverse support to the trigger element 5 when the button 3 is pressed, preventing excessive displacement of the trigger element 5 and thus preventing connection failure. As a result, the transmitter can maintain a sensitive, stable, and reliable button 3 response even after long-term use. In addition, this embodiment optimizes the internal structural layout of the transmitter, utilizing the existing battery 6 inside the transmitter as a support component to support the trigger element 5, eliminating the need for additional support or reinforcement structures, making the internal structure more compact and further improving space utilization.

[0063] In some examples, the battery 6 may be glued to the housing 1 and / or the cover 2 to secure the battery 6.

[0064] Reference Figure 6 In some embodiments, a gap exists between the trigger element 5 and the battery 6. It is understood that the battery 6 generates heat during operation, and this heat causes it to expand, resulting in slight deformation. In this embodiment, the gap between the trigger element 5 and the battery 6 is a reserved gap to allow for the expansion of the battery 6, preventing the battery 6 from compressing the trigger element 5 when it expands. Specifically, the battery 6 heats up during normal operation with minimal dimensional change, so the reserved gap can be on the micrometer scale, without affecting the support of the battery 6 for the trigger element 5 when it is pressed.

[0065] Reference Figure 8 In some embodiments, the transmitter includes a microphone 71, a protective element 72, and a waterproof mesh 73. The microphone 71 is mounted on the housing 1, and the protective element 72 surrounds the microphone 71 and is connected to the housing 1. The protective element 72 has a pickup port, and the waterproof mesh 73 covers the pickup port. Thus, the waterproof mesh 73 provides a certain degree of waterproofing, blocking liquids and preventing external impurities such as dust from entering. Furthermore, the mesh structure of the waterproof mesh 73 ensures unobstructed access to the pickup port, balancing protective performance and sound pickup quality. The protective element 72 may have a tubular structure, surrounding the microphone 71 and providing protection to its periphery.

[0066] In some examples, the transmitter also includes a locking ring 74 that fits around the edge of the waterproof mesh 73 and is connected to the inner wall of the protective member 72, thereby locking the waterproof mesh 73 to the protective member 72. Specifically, the locking ring 74 may snap or adhere to the inner wall of the protective member 72.

[0067] In some embodiments, the transmitter further includes absorbent cotton disposed between the waterproof mesh 73 and the microphone core 71. Thus, the waterproof mesh 73 acts as a first waterproof barrier, preventing large amounts of water from entering the absorbent cotton. When some water passes through the waterproof mesh 73, the absorbent cotton acts as a second waterproof barrier, absorbing the water that has passed through the mesh 73 and preventing further water intrusion into the inner cavity. Once the absorbent cotton dries, the pickup function is restored.

[0068] In some embodiments, the waterproof mesh 73 is a nano-waterproof mesh 73. Specifically, the nano-waterproof mesh 73 employs a microporous structure, allowing sound to pass through almost unimpeded while effectively preventing the infiltration of rainwater, sweat, beverages, and other liquids, thus preventing short circuits or corrosion of the internal circuitry. Therefore, the nano-waterproof mesh 73 can protect internal precision components from water and dust, while maximizing the clarity and integrity of sound transmission.

[0069] Reference Figure 8 In some embodiments, the transmitter further includes a windproof cotton bracket 75 and a windproof cotton cover. The windproof cotton cover bracket is fitted over the protective member 72, and the windproof cotton cover is fitted over the windproof bracket. Thus, this structure, through the dual cooperation of the windproof cotton bracket 75 and the windproof cotton cover, effectively reduces the interference of external airflow on the microphone core 71 of the transmitter, ensuring the sound pickup quality. Moreover, the windproof cotton cover can serve as an initial protective barrier to prevent the intrusion of external impurities such as dust.

[0070] Reference Figures 9 to 12 In some embodiments, the transmitter further includes: a PCB board 81, an antenna bracket 82, an antenna 83, and a connecting terminal 84. The PCB board 81 is disposed inside the housing 1; the antenna bracket 82 is connected to the housing 1 and is located between the housing 1 and the PCB board 81; the antenna 83 is laser-formed onto the antenna bracket 82; the connecting terminal 84 is fixedly connected to the side of the antenna bracket 82 facing the PCB board 81, and is electrically connected to the antenna 83, and is soldered to the PCB board 81. Thus, by soldering the connecting terminal 84 to the PCB board 81, not only is an electrical connection achieved, but a mechanical fixing function is also provided. Compared to traditional spring-loaded connections, this is more stable and reliable, ensuring signal transmission stability even after long-term use. Furthermore, compared to wire connections, this application avoids assembly difficulties caused by messy wire arrangement and reduces internal space occupation, making the transmitter's internal structure more streamlined and compact.

[0071] In some embodiments, the antenna 83 includes a main body portion and a connecting portion that are interconnected; the main body portion is located on the side of the antenna bracket 82 away from the PCB board, and the connecting portion extends to the side of the antenna bracket 82 facing the PCB board 81. Thus, the main body portion of the antenna 83 is located on the side of the antenna bracket 82 away from the PCB board 81, thereby reducing the interference of components on the PCB board 81 on the radiated signal of the antenna 83, which is beneficial to maintaining the stable radiation performance of the antenna 83.

[0072] Specifically, the main body of antenna 83 is the effective working area responsible for signal transmission in the antenna 83 structure. It is a large radiator and is located on the side away from PCB board 81, which can form a physical gap with PCB board 81 by utilizing the thickness of antenna bracket 82. The connecting part of antenna 83 is a line extending from the main body. It goes around to the side of antenna bracket 82 facing PCB board 81 and connects to connecting terminal 84 to facilitate connection between connecting terminal 84 and PCB board 81.

[0073] Reference Figure 11 and Figure 12 In some embodiments, the antenna support 82 includes a positioning plate 821 and a support plate 822 connected to each other; the main body is located on the support plate 822, and the connecting plate portion 41 is located on the positioning plate 821; the connecting terminal 84 is fixedly connected to the positioning plate 821, and the positioning plate 821 is also connected to the inner wall of the housing. Thus, the antenna support 82 is divided into two parts, structurally separating the radiation function and the structural positioning function of the antenna 83, making it less likely for the two functions to interfere with each other. The support plate 822 mainly supports the main body of the antenna 83, while the positioning plate 821 mainly serves a positioning function. The positioning plate 821 can not only be soldered to the PCB board 81 via the connecting terminal 84, but can also be connected to the inner wall of the housing; therefore, the PCB board 81 can also be stably connected to the housing.

[0074] In some traditional transmitters, the charging pins are typically soldered onto the transmitter's mainboard 811. Specifically, the mainboard 811 has slots, and the pins are pre-bent 90 degrees before being inserted into these slots to ensure contact with the mainboard 811, before soldering. However, stress concentration can easily occur at the bent pin locations, leading to fatigue cracking of the solder joints after prolonged use.

[0075] Reference Figures 13 to 15In some embodiments, the transmitter includes a PCB board 81, a connector 85, and pins 86. The PCB board 81 includes a main board 811 and a daughter board 813. The main board 811 is disposed inside the housing and has a first guide 812. The daughter board 813 is perpendicular to the main board 811, and the end of the main board 811 abuts against the side of the daughter board 813. The daughter board 813 has a second guide 814, and the first guide 812 and the second guide 814 are connected. The connector 85 is disposed on the side of the daughter board 813 away from the main board 811, and the side of the connector 85 backing the ion plate 813 abuts against the inner wall of the housing. The pins 86 are fixed inside the connector 85 and pass through the connector 85. The end of the pins 86 is connected to the daughter board 813. Therefore, by setting a daughter board 813 perpendicular to the motherboard 811 and directly soldering the pins 86 to the daughter board 813, the pins 86 can achieve electrical connection without bending, reducing the risk of fatigue cracking of the solder joints due to long-term use. Simultaneously, since the end of the motherboard 811 abuts against the side of the daughter board 813, and the connector 85 abuts against the inner wall of the housing, the daughter board 813 and motherboard 811 make a tighter fit when the pins 86 are inserted; when pulled out, the connector 85 can abut against the inner wall of the housing. Thus, during insertion and removal, the overall structure can effectively absorb and distribute the force during the process, significantly reducing the impact on the pins 86 and solder joints. Furthermore, the daughter board 813, connector 85, and pins 86 are all located in the end area of ​​the motherboard 811, avoiding component overlap in the transmitter thickness direction, which is beneficial for achieving an ultra-thin transmitter design and making the overall structure of the transmitter more compact.

[0076] In some embodiments, the first guide 812 extends to the end of the main board 811, and the end of the first guide 812 corresponds to the position of the second guide 814. The first guide 812 and the second guide 814 are soldered together. Specifically, the daughter board 813 can function as a circuit converter, and both the main board 811 and the daughter board 813 are etched circuit boards. The first guide 812 and the second guide 814 are conductive lines disposed on the substrate. The contact points of the first guide 812 and the second guide 814 can be connected by soldering, so that the first guide 812 and the second guide 814 can not only conduct electricity, but the main board 811 and the daughter board 813 can also be mechanically fixed. In addition, soldering the first guide 812 and the second guide 814 can not only improve the connection stability, but also simplify the internal structure. Conversely, if the main board 811 and the daughter board 813 are connected by wires, it is easy to cause the internal structure of the transmitter to be messy and redundant.

[0077] Reference Figure 14In some embodiments, the motherboard 811 includes an abutment portion 815. The abutment portion 815 protrudes from the middle region of the motherboard 811 toward the daughterboard 813, and a first guide 812 extends to the end of the abutment portion 815, which abuts against the daughterboard 813. Thus, the protruding abutment portion 815 provides better contact with the daughterboard 813. It is understood that the smaller and more concentrated area of ​​the protruding abutment portion 815, and the smaller contact area with the daughterboard 813, allows for sufficient contact between the abutment portion 815 and the daughterboard 813, reducing solder gaps caused by poor fit. Conversely, without the abutment portion 815, the entire end region of the motherboard 811 would need to be firmly abutted against the daughterboard 813. Because the contact area between the end of the motherboard 811 and the daughterboard 813 is relatively large, and there may be slight unevenness at the end of the motherboard 811, the motherboard 811 and the daughterboard 813 may not fit together fully, resulting in problems such as poor soldering at the solder joints of the first guide 812 and the second guide 814.

[0078] In some embodiments, the transmitter further includes an indicator light and a light guide. The indicator light is located on the main board 811, and the light guide extends through the housing 1, with the position of the light guide corresponding to the indicator light. The light guide is made of transparent material, allowing the light from the indicator light to pass through the light guide and exit the housing. Thus, the user can perceive the transmitter's operating status through the light from the indicator light.

[0079] Reference Figures 16 to 23 In some embodiments, the transmitter includes a first magnetic chuck 91, a magnetic clip 92, and an elastic clip 93. The first magnetic chuck 91 is fixed to the transmitter, the magnetic clip 92 has a second magnetic chuck 921, and the elastic clip 93 has a third magnetic chuck 931. The first magnetic chuck 91 is magnetically connected to either the second magnetic chuck 921 or the third magnetic chuck 931. When the second magnetic chuck 921 is magnetically connected to the first magnetic chuck 91, the second magnetic chuck 921 and the first magnetic chuck 91 work together to clamp onto an external object. When the third magnetic chuck 931 is magnetically connected to the first magnetic chuck 91, the elastic clip 93 clamps onto the external object. Thus, in this embodiment, the first magnetic chuck 91 on the transmitter can serve as a universal connection base, achieving a detachable connection with the magnetic clip 92 or the elastic clip 93 through magnetic attraction, making the connection convenient and quick. Users can choose either the magnetic clip 92 or the elastic clip 93, depending on the thickness of their clothing or the intended use. The other clip can then be stored in the storage box, preventing it from remaining on the transmitter. This avoids structural redundancy in the transmitter and prevents issues such as an overly heavy transmitter or the transmitter protruding and snagging on clothing. This design allows for a clean and compact transmitter, reducing the feeling of discomfort when wearing it and meeting the requirements for portability and lightweight design.

[0080] Reference Figure 19In some embodiments, the magnetic clip 92 includes a box body 922 and a box cover 923; the box body 922 has a receiving cavity and an opening communicating with the receiving cavity, and the second magnetic member 921 is located in the receiving cavity; the box cover 923 closes to the opening. Thus, the magnetic clip 92 can be in the shape of a flat box with a neat appearance, and the box body 922 and the box cover 923 can protect the second magnetic member 921, preventing the second magnetic member 921 from direct contact with the outside world, and also preventing the magnet from being damaged or falling off due to bumps or wear during use or storage.

[0081] In some embodiments, the lid 923 and the body 922 can be bonded together. This bonding method ensures a secure and seamless connection between the lid 923 and the body 922, effectively preventing the lid 923 from falling off, while also simplifying the assembly structure and making the overall structure more compact and reliable.

[0082] Reference Figure 20 In some embodiments, the elastic clip 93 includes a connecting disc 932 and a clamping plate 933; the connecting disc 932 has a receiving groove 934, and a third magnetic member 931 is connected to the receiving groove 934, with the connecting disc 932 attached to the transmitter via the third magnetic member 931; the connecting disc 932 and the clamping plate 933 cooperate to clamp onto an external object. Thus, the third magnetic member 931 can be embedded in the receiving groove 934, rather than protruding from the surface of the connecting disc 932. Furthermore, the receiving groove 934 also serves as a limiting function, preventing displacement of the third magnetic member 931 and ensuring precise magnetic attraction between the third magnetic member 931 and the first magnetic member 91.

[0083] In some examples, the third magnetic element 931 can be attached to the receiving groove 934.

[0084] In some embodiments, the elastic clip 93 further includes a torsion spring and a rotating shaft; the rotating shaft passes through the connecting plate 932, the clamping plate 933, and the torsion spring, respectively, and the two ends of the torsion spring abut against the connecting plate 932 and the clamping plate 933, respectively, allowing the connecting plate 932 and the clamping plate 933 to rotate around the rotating shaft. Specifically, both the connecting plate 932 and the clamping plate 933 are provided with connecting portions, and the rotating shaft passes through two connecting portions respectively. In this embodiment, the end of the elastic clip 93 away from the rotating shaft can remain pressed against each other under the action of the elastic restoring force of the torsion spring. When it is necessary to clamp the elastic clip 93 onto clothing, the user presses the area of ​​the elastic clip 93 near the rotating shaft to separate the ends of the connecting plate 932 and the clamping plate 933 away from the rotating shaft, allowing the collar to be inserted. After the user releases the elastic clip 93, the elastic clip 93 is clamped onto the clothing.

[0085] Reference Figure 23In some examples, the cover plate 2 has a connecting groove 23 on the side facing the inner cavity, and the first magnetic member 91 is connected to the connecting groove 23. Thus, the first magnetic member 91 is located inside the transmitter, and the connecting groove 23 provides a limiting effect on the first magnetic member 91, ensuring that the first magnetic member 91 remains at a preset magnetic interface. In some examples, the first magnetic member 91 can also be adhered to the connecting groove 23.

[0086] Reference Figure 22 In some embodiments, the transmitter further includes a positioning element 10, which is connected to the side of the cover plate 2 opposite to the connecting groove 23. The positioning element 10 has a positioning groove 101, and the magnetic clip 92 and / or elastic clip 93 are provided with positioning blocks 935 adapted to the positioning groove 101. Thus, the cooperation between the positioning groove 101 and the positioning block 935 enables faster and more accurate installation of the magnetic clip 92 or elastic clip 93, further reducing the operational difficulty during connection. In addition, the cooperation between the positioning groove 101 and the positioning block 935 effectively prevents the magnetic clip 92 or elastic clip 93 from rotating after magnetic connection, ensuring that the magnetic clip 92 or elastic clip 93 and the transmitter always remain in the preset position.

[0087] In summary, in the transmitter housing provided in this application, the first enclosure 11 and the second enclosure 12 can form a stepped structure. Since the first abutting part 21 abuts against the first enclosure 11 and the second abutting part 22 abuts against the second enclosure 12 respectively, a tortuous sealing path can be formed at the mounting opening of the outer casing 1, thereby effectively extending the water penetration path and reducing the risk of liquid directly intruding into the inner cavity. When the transmitter falls into water or is in a high-pressure water environment, the multi-stage abutting structure can disperse and withstand the external water pressure impact, avoiding pressure concentration on a single sealing interface, thereby significantly improving the sealing stability and waterproof durability in deep water or high-pressure spray environments.
