Description

An intercom that is easy to trigger with a button Technical Field

[0001] The present invention relates to the field of intercoms, and in particular to an intercom that is easy to trigger with a button. Background Art

[0002] A walkie-talkie is a portable device used for wireless communication, allowing users to conduct two-way voice communication over relatively short distances. First, walkie-talkies support group calling, allowing simultaneous voice communication with multiple people, facilitating team collaboration and collective communication. Furthermore, walkie-talkies are portable, lightweight, and easy to carry, allowing users to carry them with them and communicate at any time. Walkie-talkies do not rely on an internet connection or a mobile phone signal and can be used without a network connection, making them suitable for environments with no network coverage or inadequate communication infrastructure. Finally, walkie-talkies typically have a rugged design that can withstand significant impact and harsh environments, making them suitable for use in harsh conditions such as outdoor and industrial environments. In summary, walkie-talkies offer significant advantages in terms of immediacy, group calling, portability, independent communication, and durability, making them widely used in many industries and scenarios.

[0003] The buttons on existing intercoms typically occupy a small area within the product, requiring users to shift their sight to the product for precise control. In some special situations, such as while driving or cycling, intercoms often require blind operation. The small buttons are inconvenient to operate and can even lead to safety accidents.

[0077] Example 1

[0078] This embodiment provides a walkie-talkie that is easy to trigger by pressing a button, including a first button 5, a support portion 4 and a shell 1. The shell 1 is flat, with a back surface 17 for wearing on the human body and a front surface 16. The pressable portion of the press surface 16 is the press portion 2, and the press surface 16 also includes a fixing portion 14 for fixing the press portion 2. The support portion 4 and the first button 5 are arranged in the shell 1, and the first button 5 is electrically integrated on the circuit board and faces the pressing surface 16. The pressing portion 2 is arranged in the rebound direction of the first button 5. In this embodiment, the pressing portion 2 is arranged above the first button 5, and the first button 5 is located at the center of the pressing portion 2 so that the first button 5 can be better triggered and rebound. The support portion 4 is a printed circuit board (PCB). The support portion 4 can also be a component or structure located in the shell 1, such as a bracket that can support and fix the first button 5.

[0079] Preferably, the pressing portion 2 corresponds to a first button 5. When the pressing portion 2 corresponds to multiple first buttons 5, the first buttons 5 are arranged according to a certain pattern. For example, first buttons 5 are placed at regular angles around the center of the pressing portion 2. Multiple first buttons 5 with different functions can be provided on the circuit board, so that different function buttons are triggered when the pressing portion 2 is pressed in different areas and directions. For example, a first button 5 is provided below the central area of ​​the pressing portion 2, and four first buttons 5 are evenly arranged around the first button 5, so that one pressing portion 2 corresponds to five first buttons 5. When pressed toward the center of the pressing portion 2, the first button 5 in the center is triggered. Pressing the pressing portion 2 at an angle in four different directions can trigger four first buttons 5 with different functions. Using one pressing portion 2 to correspond to multiple different first buttons 5 can reduce the number of pressing portions 2, increase the area of ​​the pressing portion 2, and make it easier to control. Furthermore, by controlling the direction of the pressing portion 2 to trigger different buttons, it is not necessary to identify the specific location of the pressing portion 2, which is beneficial for blind field operation. Preferably, the area where the pressing portion 2 is located occupies 10% to 100% of the pressing surface 16. The larger the proportion of the pressing portion 2 on the pressing surface 17, the easier it is to trigger the button. The width of an adult male's thumb is about 2 cm, the width of the index finger, middle finger, and ring finger is between 1.5 and 2 cm, and the width of the little finger is generally between 11.5 cm. Women's fingers are relatively slender. Generally, the width of a female index finger is about 2.5 mm narrower than that of a male index finger. If only the effects of osteoarthritis, thick joints, and finger force are considered, the width of each person's finger may vary by about 2 mm to 4 mm. The size of the walkie-talkie can be compressed to about 90 mm. Combined with the deformation of the finger when pressing, expanding the proportion of the pressing portion 2 on the pressing surface 17 to 10% can ensure the effective pressing area of ​​the button to ensure that the user can perform an effective pressing action.

[0080] In the first embodiment, the pressing portion 2 is connected to the fixing portion 14 via the connecting portion 6, and is configured to trigger the first button 5 when pressed by an external force. The connecting portion 6 is preferably made of a flexible material, including rubber or a polymer material such as polyethylene, polypropylene, or polyurethane. Flexible materials can deform without breaking, and thus adapt well to the upward and downward movement of the pressing portion 2. After the pressing portion 2 is pressed downward by an external force and triggers the first button 5, the pressing portion 2 is reset primarily by the resilience of the first button 5.

[0081] In a second embodiment, the pressing portion 2 is made of a flexible material to generate resistance when pressed by an external force and to generate a rebound force for resetting after triggering the first button 5. The pressing portion 2 is fixedly connected to the fixing portion 14, for example, by hot-melt connection or adhesive connection. The pressing portion 2 itself can provide a large rebound force after being pressed. Combined with the rebound force of the first button 5, the pressing portion 2 is reset faster, providing a better pressing feel and a rebound feel when the pressing portion 2 is reset. In this embodiment, the connection between the fixing portion 14 and the pressing portion 2 is recessed 7 in the direction of the first button 5, and the depth of the recess 7 corresponds to the thickness of the pressing portion 2. For example, if the thickness of the edge of the pressing portion 2 is 2 mm, the connection between the fixing portion 14 and the pressing portion 2 is recessed 2 mm in the direction of the first button 5, so that the surface of the fixing portion 14 and the surface of the pressing portion 2 are more smoothly connected, thereby enhancing the aesthetic appearance.

[0082] In the third embodiment, the housing 1 is further provided with a snap-fit ​​bracket 9, and the edge 8 of the pressing portion snaps onto the inner wall of the fixing portion 14. The pressing portion 2 is connected to the edge 8 of the pressing portion so as to be positioned in the direction of the key's rebound. In this embodiment, the edge 8 of the pressing portion is snapped onto the inner wall of the fixing portion 14 via the snap-fit ​​bracket 9, which prevents the pressing portion 2 from loosening and increases its firmness.

[0083] In the fourth embodiment, an inner bracket 12 and an elastic member 10 are further provided in the shell 1. The shell 1 is divided into a bottom shell 11 and a pressing shell 13. The pressing surface 16 is located on the pressing shell 13, and the wearing surface 17 is located on the bottom shell 11. The inner bracket 12 is located in the pressing shell 13, and the inner bracket 12 is connected to the bottom shell 11. An inner space for accommodating the elastic member 10 is provided between the inner bracket 12 and the inner side wall of the pressing shell 13. The elastic member 10 is preferably a spring or a shrapnel. The bottom shell 11 is movably connected to the pressing shell 13, and the movable direction is the triggering direction and the rebound direction of the first button 5. The inner bracket 12 is used to limit the range of movement of the bottom shell 11 and the pressing shell 13 in the triggering direction of the first button 5. The elastic member is used to generate a rebound force to reset the pressing shell 13 and the pressing part 2 after the first button 5 is triggered. The inner bracket 12 includes an overhead portion arranged in the rebound direction of the first button 5. A button hole is provided at the position of the overhead portion corresponding to the first button 5. The trigger head of the first button 5 passes through the button hole to trigger the first button 5 when the pressing portion 2 or the pressing shell 13 is pressed.

[0084] Preferably, the housing 1 further includes a side pressing surface 3 located between the pressing surface 16 and the wearing surface 17. The side pressing surface 3 is provided with a second button 15, which is electrically integrated on the circuit board and located on the side pressing surface 3. The housing 1 also includes a microphone and a speaker electrically connected to the circuit board, and both the microphone and the speaker are located on the side pressing surface 3.

[0085] The intercom of the present invention triggers the button through the pressing part 2 mounted on the button. The pressing part 2 occupies more than 10% of the front surface and can reach a maximum of 100%, so that the area of ​​the pressing part on the surface of the product is large enough to facilitate the user's blind field and single-handed operation of the intercom, thereby improving the user experience.

[0086] Example 2

[0087] This embodiment provides an intercom that is easy to trigger with a button, including a first button 5, a support portion 4 and a housing 1, and further including: a speaker 201 and a microphone 202;

[0088] Optionally, the speaker 201 may be a horn; the housing 1 has a thickness direction, a height direction, and a width direction that are orthogonal to each other, the thickness direction being defined as the direction toward or away from one side of the human body when worn; the height direction being defined as the direction extending from the head and feet of the human body; the thickness direction being perpendicular to the height direction and the width direction respectively;

[0089] Specifically, as shown in Figures 7 to 18, the thickness direction is the Z-axis direction shown in the coordinate axis of the figure, the height direction is the Y-axis direction shown in the coordinate axis, and the width direction is the X-axis direction shown in the coordinate axis;

[0090] As shown in FIG7 to FIG10, the housing 1 has a wearing surface 102 close to the human body along the thickness direction and a pressing surface 16 away from the human body along the thickness direction;

[0091] When worn, the vibration direction of the speaker 201 and the microphone 202 is between the height direction and the width direction, and is toward the head position of the human body.

[0092] The orientation of the speaker 201 helps reduce the scattering and attenuation of sound in the air, thereby improving the clarity and accuracy of the sound; and also helps reduce the interference of ambient noise on sound transmission.

[0093] The microphone 202 mainly receives sounds from the direction it faces rather than noise from the surrounding environment.

[0094] Furthermore, as shown in FIG9 and FIG12 , the housing 1 further includes a side pressing surface 3 connecting the wearing surface 102 and the pressing surface 16 ; a sound outlet 301 and a sound receiving hole 302 are provided on the side pressing surface 3 , wherein the sound outlet 301 is provided in the vibration direction of the speaker 201 , and the sound receiving hole 302 is provided in the vibration direction of the microphone 202 ;

[0095] In the wearing state, as shown in FIG15 and FIG16 , when viewed along the thickness direction, the angle between the extension direction of the sound outlet 301 of the speaker 201 and the height direction is between 0 degrees and 63.5 degrees;

[0096] As shown in FIG. 18 , when viewed along the width direction, the angle between the extension direction of the sound outlet 301 of the speaker 201 and the height direction is between 0 degrees and 80.5 degrees.

[0097] Within the above range, the propagation effect of the speaker 201 is relatively good, which helps to optimize the user experience and ensure that the sound is relatively clear and the sound quality is relatively good.

[0098] Furthermore, as shown in FIG9 to FIG12 , the speaker 201 and the microphone 202 are arranged on the same side;

[0099] On the one hand, it can solve the problem of echo and howling caused by sound propagating in the air when the speaker 201 and the microphone 202 are close to each other but located on different sides of the pressing surface 3; arranging the speaker 201 and the microphone 202 on the same side can reduce echo and howling, providing clearer voice transmission;

[0100] On the other hand, the speaker 201 and the microphone 202 are arranged on the same side, which is convenient for the user to operate and control: when wearing it, the user can more naturally face the speaker 201 and the microphone 202 towards themselves, which is convenient to use without excessive posture adjustment, thereby improving the user experience;

[0101] On the other hand, arranging the loudspeaker 201 and the microphone 202 on the same side can also help optimize the spatial layout and design of the intercom, making the intercom thinner and more portable.

[0102] Furthermore, as shown in FIG9 , a lanyard hole 51 for connecting a lanyard is provided on one side of the housing 1 where the speaker 201 and the microphone 202 are provided, so that the intercom can be hung and worn.

[0103] Furthermore, as shown in FIG13 and FIG14 , a back clip 61 is further provided on the housing 1, and a magnetic attraction module is further provided on the wearing surface 102 along the thickness direction;

[0104] The magnetic module includes a magnetic block (not shown in the figure) provided on the housing 1 and a magnetic seat 71 used in conjunction with the magnetic block.

[0105] Through the cooperation of the magnetic block and the magnetic seat 71, the clothes can be clamped and are easy to wear;

[0106] The back clip 61 and the magnetic module are used to realize different wearing methods.

[0107] Specifically, the wearing effects are shown in Figures 15 to 18. The diverse wearing methods are more convenient to operate and carry, allowing users to choose the most suitable method according to specific scenarios and needs, meeting users' diverse usage needs.

[0108] Furthermore, the sound outlet 301 of the speaker 201 and the sound receiving hole 302 of the microphone 202 are oriented in different directions, and the propagation path of the sound of the speaker 201 is different from the propagation path of the sound of the microphone 202;

[0109] The sound outlet 301 is a sound emitting hole, that is, the sound propagation path of the speaker 201 and the sound receiving path of the microphone 202 are different, and there is no intersection or the intersection is very limited, thereby reducing the interference between them;

[0110] The microphone 202 and the speaker 201 are oriented in different directions, which can effectively avoid the occurrence of echo and improve the clarity of the sound;

[0111] On the other hand, such a design ensures that the sound propagation path of the speaker 201 does not pass directly through the microphone 202, thereby reducing the interference of non-direct sound waves on the microphone 202 and improving the directional performance of the microphone 202; this can enable the microphone 202 to receive sounds in a specific direction more concentratedly, thereby improving the quality and clarity of the voice signal.

[0112] In summary, the different orientations of the intercom microphone 202 and the speaker 201 can reduce echoes, improve the directivity and clarity of sound, and reduce noise and environmental interference. These factors work together to improve the sound quality of the intercom and optimize the user experience.

[0113] Furthermore, a cavity 41 is provided on the housing 1 , and the speaker 201 and the microphone 202 are provided in different cavities 41 ;

[0114] This design actually separates the positions of the speaker 201 and the microphone 202, which is also commonly referred to as acoustic isolation or acoustic separation.

[0115] The cavity 41 protects the speaker 201 and the microphone 202 from the external environment, isolating most of the external noise. The sound is received through the sound receiving hole 302 and released through the sound outlet 301, thereby enhancing the directionality of the sound reception and release.

[0116] Specifically, inside the intercom, when the distance between the speaker 201 and the microphone 202 is too close, the sound may produce an echo and affect the sound reception effect of the microphone 202. At the same time, the sound output by the speaker 201 may also directly enter the microphone 202, causing noise or interference; by separating the positions of the speaker 201 and the microphone 202, the possibility of echo and interference can be effectively reduced, thereby improving the clarity and purity of the sound effect.

[0117] In addition, when the speaker 201 and the microphone 202 are too close to each other, the surrounding environmental noise will be amplified and diffused, affecting the quality of the sound effect.

[0118] In summary, in a walkie-talkie, locating the speaker 201 and the microphone 202 in different cavities 41 is an important design factor for optimizing the sound effect, which can improve the clarity and purity of the sound effect.

[0119] Furthermore, as shown in FIG8 , the cavity 41 in which the speaker 201 is provided has a size that gradually decreases from the inside to the outside along the sound propagation direction;

[0120] The cavity 41 in which the microphone 202 is disposed decreases in size from the outside to the inside along the sound propagation direction.

[0121] This design in which the size of the cavity 41 of the speaker 201 and the microphone 202 gradually decreases along the sound propagation direction is called an acoustic waveguide.

[0122] The design of gradually reducing the size of the cavity 41 of the speaker 201 and the microphone 202 along the sound propagation direction is consistent with the distance of the acoustic waveguide, which can enhance the diffusion and directivity of the sound waves, improve the focus and directionality of the sound, and optimize the sound experience of the user.

[0123] The gradually shrinking cavity 41 also reduces sound scattering. Scattering refers to the phenomenon where sound waves are reflected and diffused when they encounter obstacles or boundaries. By gradually shrinking cavity 41, the collision of sound waves with the boundaries of cavity 41 is reduced, thereby reducing sound diffusion and reflection, allowing sound to be transmitted more accurately to the target area.

[0124] During sound propagation, the energy of sound usually decays as the distance increases; the gradually shrinking cavity 41 design can control the degree of sound attenuation, so that the sound maintains higher energy and sound quality during the propagation process.

[0125] In general, gradually reducing the size of the speaker 201 and microphone 202 cavity 41 along the sound propagation direction can provide better sound focus, directionality, and accuracy. This design is commonly used in applications such as audio systems and speaker and microphone 202 arrays to improve sound propagation.

[0126] Furthermore, the number of the sound holes 301 includes one or more, and the sound holes 301 are staggered in an upper and lower arrangement;

[0127] The staggered arrangement of sound holes 301 can reduce audio issues caused by resonance or distortion. Sound waves may interfere with or reflect from other components during propagation, and the staggered arrangement of sound holes 301 can reduce this problem, thereby improving audio quality and clarity.

[0128] The embodiments of the present invention have at least the following beneficial effects:

[0129] The embodiment of the present invention provides a walkie-talkie that is easy to trigger with a button. In addition to having the function of being easy to trigger with a button, the setting position and orientation angle of the speaker 201 are optimized, which helps to improve the communication sound quality; the sound outlet holes 301 are distributed in the vibration direction of the speaker 201, and the sound receiving holes 302 are distributed in the vibration direction of the microphone 202, which further enhances the directionality of sound propagation and optimizes the position distribution relationship of the sound outlet holes 301. There is a difference in the orientation of the sound outlet holes 301 and the sound receiving holes 302. The speaker 201 and the microphone 202 are arranged in different cavities 41 on the same side. The size of the cavity 41 with the speaker 201 gradually decreases along the sound propagation direction; the size of the cavity 41 with the microphone 202 gradually increases along the sound propagation direction; under the joint action of the above designs, the clarity and purity of the sound effect are improved; a lanyard hole 51, a back clip 61, and a magnetic suction module are provided; a variety of wearing methods are provided, which is more convenient to operate and carry.

[0130] The rest of the contents that are the same as those in the first embodiment are not repeated here.

[0131] Example 3

[0132] This embodiment provides a walkie-talkie that is easy to trigger with a button. The design of the sound cavity makes the volume output by the walkie-talkie higher and louder. The structure of the walkie-talkie is shown in Figures 19-22 of the specification. The specific scheme is as follows:

[0133] A walkie-talkie that is easy to trigger by pressing a button includes a flat shell 1 and a circuit board 52 and a speaker 201 arranged in the shell 1. The shell 1 includes a wearing surface 17 for being worn on the human body, a pressing surface 16 opposite to the wearing surface 17, and a side pressing surface 3 connecting the wearing surface 17 and the pressing surface 16.

[0134] Preferably, the side pressing surface 3 is provided with a sound hole 301, and the speaker 201 is located on the circuit board 52 and emits sound toward the sound hole 301. Since the intercom is usually worn on the chest, arm, or helmet, the sound emitted by the sound hole 301 located on the side pressing surface 3 can be better heard by the user in these wearing methods, thereby improving the user experience. In other embodiments, the sound hole 301 is located on the pressing surface 16, in which case the intercom is best worn on the shoulder.

[0135] Exemplarily, the overall shape of the housing 1 is flat. This flat shape contributes to the stability of the housing 1 and prevents the walkie-talkie from rolling when worn via the lanyard. In a first embodiment, as shown in Figures 19 and 20, the housing 1 is shaped like a pancake, and the side pressing surface 3 is a curved surface with a certain curvature, which makes the overall appearance of the walkie-talkie rounded and improves the grip. In a second embodiment, as shown in Figures 21 and 22, the housing 1 is shaped like a square box. In other embodiments, the shape of the housing 1 can also be a hexagonal box or an octagonal box. Preferably, the distance from the wearing surface 17 to the pressing surface 16 is greater than 6 mm and less than 35 mm. Because the housing 1 contains components such as the circuit board 52 and the battery 11a, and to maintain a certain structural strength, the distance from the wearing surface 17 to the pressing surface 16 is greater than 6 mm. A distance of less than 35 mm from the wearing surface 17 to the pressing surface 16 facilitates wearing and holding the walkie-talkie and makes it easier to fit in a pocket. Specifically, the distance between the wearing surface 17 and the pressing surface 16 is the thickness of the flat housing 1. When the housing 1 is at its thinnest, while ensuring structural strength, the thickness of the wearing surface 17 and the pressing surface 16 are 0.6 mm. Furthermore, to reduce the thickness of the housing 1, the battery 11a is a low-thick battery 11a, and the circuit board 52 within the housing 1 can be placed side by side with the battery 11a.

[0136] Specifically, as shown in FIG19 , the internal space of the housing 1 directly above the circuit board 52 is a first space 9a close to the pressing surface 16, and directly below the circuit board 52 is a second space 10a close to the wearing surface 17. A rear sound cavity 12a located at the rear of the speaker 201 for enhancing the sound effect of the speaker 201 is provided in the first space 9a and / or the second space 10a. The volume of the rear sound cavity 12a is greater than 0.5cc and less than 8cc. "cc" is the abbreviation of "cubic centimeter" and can also be expressed as "cm 3The volume of the rear acoustic cavity 12a can be adjusted between 0.5cc and 8cc according to different needs. Since the first space 9a and the second space 10a are affected by the size of the housing 1 and electronic devices and circuits are installed therein, the rear acoustic cavity 12a located in the first space 9a and the second space 10a is limited to less than 8cc. Secondly, when the volume of the rear acoustic cavity is larger than 8cc, its volume change will have a relatively small impact on the low-frequency performance. When the volume of the rear acoustic cavity 12a is less than 0.5cc, low-frequency signals have difficulty passing through the rear acoustic cavity 12a, resulting in poor bass effect and low volume output by the intercom.

[0137] Furthermore, the rear sound cavity 12a is preferably a sealed cavity, which can effectively isolate interference from external sounds and noise, providing more accurate and clear sound effects. In other embodiments, the rear sound cavity 12a is an unsealed cavity. Unsealed cavities can increase the extension and depth of low-frequency response, but are also susceptible to external noise and interference.

[0138] Preferably, the speaker 201 is located at an edge of the circuit board 52 and is perpendicular to the circuit board 52. The first space 9a and the second space 10a are located at the rear of the speaker 201. The rear sound cavity 12a is provided in both the first space 9a and the second space 10a. In other embodiments, for example, the sound outlet 301 is located in the pressing surface 16. In this case, the speaker 201 is located in the first space 9a, and the rear of the speaker 201 is located in the first space 9a. Therefore, the rear sound cavity 12a is provided only in the first space 9a.

[0139] Furthermore, an inner bracket 62 and an antenna 13a are provided in the housing 1. The antenna 13a is used to receive and transmit radio signals. The antenna 13a is electrically connected to the circuit board 52. The inner bracket 62 is used to set up the antenna 13a in the first space 9a. The components, circuits, etc. on the circuit board 52 may block or interfere with the wireless signal. For example, if the layout distance between the high-frequency circuit and the antenna is too close, it may cause mutual interference. In addition, the signal lines on the circuit board 52 may generate crosstalk, causing problems such as mutual interference and cross-coupling of signals. Therefore, setting up the antenna 13a on the circuit board 52 can improve the communication range and communication quality of the walkie-talkie.

[0140] Preferably, the inner bracket 62 connects the edge of the circuit board 52 and the inner wall of the housing 1, which can improve the sealing of the intercom. The speaker 201 is located within the inner bracket 62. A front sound cavity 14a is formed between the front of the speaker 201 and the inner bracket 62. When the speaker 201 pushes air forward, the air in the front cavity rebounds, forming a resonance effect, which increases the sound pressure of the sound wave, reduces high-frequency noise, and outputs the sound to a greater distance.

[0141] Furthermore, a battery 11a for power supply is provided in the shell 1, and the battery 11a is located in the second space 10a. The shape of the battery 11a is preferably flat, and is stacked up and down with the circuit board 52 to reduce the thickness of the walkie-talkie. A microphone 202 is also provided in the shell 1, and a sound receiving cavity 18a is formed between the inner bracket 62 and the inner wall of the shell 1. The microphone 202 is located in the sound receiving cavity 18a, and a sound receiving hole 302 is provided in the shell 1 corresponding to the sound receiving cavity 18a. Walkie-talkies are often used outdoors or in windy environments, and wind noise can cause great interference to voice communications. The sound receiving cavity 18a can play a certain windproof effect. When strong wind enters the sound receiving hole 302 and the sound receiving cavity 18a at an angle, the sound receiving cavity 18a can attenuate the flow rate and pressure of the airflow, reduce the impact of wind noise on the microphone 202, and improve the clarity of voice communication.

[0142] Preferably, the sound receiving hole 302 is located on the side pressing surface 3. Similar to the sound outlet hole 301, the sound receiving hole 302 located on the side pressing surface 3 can better collect the sound of the user speaking, so that the user's sound waves are directly facing the sound receiving hole 302. In other embodiments, the sound receiving hole 302 is located on the pressing surface 16. In this case, it is suitable for wearing the walkie-talkie close to the throat, so that when the user lowers his head, he is facing the sound receiving hole 302. Preferably, the housing 1 is also provided with a first button 5 and a second button 15 electrically connected to the circuit board 52, with the first button 5 facing the pressing surface 16 and the second button 15 facing the side pressing surface 3.

[0143] Furthermore, the sound outlet 301 and the sound receiving hole 302 are oriented in different directions, and the sound propagation path of the speaker 201 is different from the sound receiving path of the microphone 202. Preferably, when worn, the sound receiving hole 302 faces the human mouth, and the sound outlet 301 faces the human ear. In a first embodiment, the shape of the housing 1 is similar to a pancake, and the sound outlet 301 and the sound receiving hole 302 are located on the arc-shaped side pressing surface 4. In a second embodiment, the shape of the housing 1 is similar to a square box, and the side pressing surface 3 is a plurality of side planes. Preferably, the sound outlet 301 and the sound receiving hole 302 are located in the same side plane.

[0144] Exemplarily, a depressible pressing portion 2 is provided on the pressing surface 16 to trigger the first button 5 when pressed by an external force. In a first embodiment, as shown in FIG5 , the depressible pressing portion covers the entire pressing surface 16 , facilitating control of the first button 5. In a second embodiment, as shown in FIG22 , a depressible pressing portion 2 is provided on a portion of the pressing surface 16 .

[0145] Beneficial Effects: The present invention provides a walkie-talkie that is easy to trigger with a key. In addition to the key-activated function, a rear sound cavity 12a is provided in the first space 9a and / or the second space 10a within the housing 1, making the sound clearer, more natural, and more balanced, and increasing the amplitude and intensity of the sound, resulting in a higher volume and louder sound output by the walkie-talkie. Furthermore, the volume of the rear sound cavity is greater than 0.5cc and less than 8cc, which can enhance low-frequency sound waves, making low-frequency sounds more mellow and improving the user experience.
