Description

Technical Field

[0001] This utility model relates to the field of explanation device technology, specifically to an explanation device that facilitates switching of working modes. Background Technology

[0002] Traditional audio guide devices typically use a top-mounted multi-button layout to control functions such as mode switching, requiring users to rely on visual positioning to accurately identify and press the corresponding buttons. However, this operating method has the following drawbacks in practical applications: In mobile scenarios (such as museum tours or industrial inspections), users need to divert their attention to view the buttons, which can easily lead to accidental mode switching due to accidental touches, affecting the user experience. In addition, special user groups (such as visually impaired individuals or those in low-light environments) may find it difficult to distinguish the buttons arranged in different positions by touch, resulting in a high operational threshold. Utility Model Content

[0003] The purpose of this invention is to propose a guide device that facilitates switching of working modes, aiming to solve the technical problems of existing guide devices that use a multi-button layout on the top, require visual interaction when operating the buttons, and have difficulties in blind operation and are prone to accidental touches.

[0004] To achieve the above objectives, this utility model proposes a guide device that facilitates switching of working modes, including a housing with a sliding groove.

[0005] A control circuit board is disposed inside the housing. The control circuit board is equipped with a DIP switch, which has a continuous radio mode and an off mode.

[0006] A microphone is disposed on the housing and is electrically connected to the control circuit board;

[0007] A sliding key assembly is movably disposed within the slide groove, and an actuating element for toggling the DIP switch is connected to the sliding key assembly, such that:

[0008] When the sliding key assembly moves to the first position of the slide groove, the toggle member moves to move the DIP switch to the continuous radio mode, and the pickup member is in the off state;

[0009] When the sliding key assembly moves to the second position of the slide groove, the toggle member moves to move the DIP switch to the off position, and the pickup member is in a continuous pickup state.

[0010] Preferably, the sliding key assembly includes a sliding button, a first assembly, and a second assembly. The sliding button is movably disposed within the slide groove and is located outside the first assembly. The first assembly is detachably disposed outside the second assembly, and the toggle member is provided on the inner side of the second assembly.

[0011] The outer sides of both ends of the first assembly abut against the inner wall of the housing. A limiting groove is provided inside the housing. The first assembly and the second assembly are movably disposed in the limiting groove. The limiting groove has a first notch. The first notch is positioned directly opposite the DIP switch, so that when the toggle member moves along the first notch, it extends to the outside of the first notch, thereby toggling the DIP switch.

[0012] Preferably, the inner side of the first assembly is provided with a hollow first mounting post, and the outer side of the second assembly is provided with a hollow second mounting post. The second mounting post is inserted into the first mounting post to form an installation space, and an elastic member is provided in the installation space.

[0013] The DIP switch has a push-button radio mode, and the control circuit board also has a button. A second notch is provided on the limiting groove, directly opposite the button. A through hole is provided on the second assembly, and an extension member is provided on the inner side of the first assembly. The extension member is inserted into the through hole, such that:

[0014] When the sliding key assembly moves to the third position of the slide groove, the toggle member moves to move the DIP switch to the key radio position. When the sliding key is pressed by external force, the elastic member is in a compressed state, the first assembly moves inward, the extension member extends out of the through hole and squeezes the button at the second notch, and the pickup member is in the pickup enabled state.

[0015] When the sliding button is not pressed, the elastic element is in an extended state, the first assembly moves outward, the extension element no longer presses the button, and the pickup element is in a pickup off state.

[0016] Preferably, the first assembly has two first mounting posts spaced apart, and the second assembly has two second mounting posts spaced apart. Each second mounting post is inserted into a corresponding first mounting post to form a corresponding mounting space, and each mounting space is provided with the elastic element.

[0017] Preferably, the outer wall of the sliding button is provided with multiple protrusions.

[0018] Preferably, the housing is provided with a first identifier, a second identifier, and a third identifier, wherein the first identifier corresponds one-to-one with the continuous radio mode, the second identifier corresponds one-to-one with the off mode, and the third identifier corresponds one-to-one with the button radio mode.

[0019] Preferably, the groove is formed on any side of the housing.

[0020] Preferably, the bottom of the limiting groove is further provided with several reinforcing ribs.

[0021] Preferably, the outer wall of the housing is further provided with a hook for fixing the audio guide.

[0022] Preferably, the sound pickup element is a microphone.

[0023] This utility model discloses a narrator with easily switchable working modes, which has the following beneficial effects: By controlling the sliding key component, users can freely switch between the following three modes: Mode 1—Sound pickup enabled / disabled state: The sliding key is at the top position within the slide groove; a light press activates sound pickup, and releasing it stops it; Mode 2—Continuous sound pickup state: The sliding key slides to the bottom of the slide groove, allowing continuous sound pickup without pressing, suitable for free narration scenarios; Mode 3—Off state: The sliding key slides to the middle of the slide groove, entering the off state. Through the above structural integration, multi-mode control is achieved through the simple structure of the sliding key component, improving operational convenience and reliability. The number of conventional buttons and electronic components is reduced, thereby reducing size and power consumption, meeting the portability requirements of handheld devices. Simultaneously, the mechanical positioning structure of the sliding key component avoids accidental operation, is user-friendly for blind operation, and has intuitive operating logic, reducing the user's learning cost.

[0037] like Figures 1 to 7 As shown, a guide device that facilitates switching of working modes includes a housing 1, which has a groove 11.

[0038] A control circuit board 2 is disposed inside the housing 1. The control circuit board 2 is provided with a DIP switch 21, which has a continuous radio position 211 and an off position 212.

[0039] A microphone 3 is disposed on the housing 1 and is electrically connected to the control circuit board 2;

[0040] The sliding key assembly 4 is movably disposed within the slide groove 11, and an actuating element 41 for toggling the DIP switch 21 is connected to the sliding key assembly 4, such that:

[0041] When the sliding key assembly 4 moves to the first position of the slide groove 11, the toggle member 41 moves to move the DIP switch 21 to the continuous radio mode 211, and the pickup member 3 is in the off state.

[0042] When the sliding key assembly 4 moves to the second position of the slide groove 11, the toggle member 41 moves to move the DIP switch 21 to the off position 212, and the pickup member 3 is in a continuous pickup state.

[0043] The audio guide in this solution is a handheld audio guide product, which is mainly suitable for mobile audio guide platforms such as classrooms and museum tours.

[0044] Specifically, the guide includes a housing 1 with an internal accommodating space. A groove 11 on the housing 1 restricts the movement of the sliding key assembly 4. Inside the housing 1 is a control circuit board 2, electrically connected to the microphone 3 to control different operating modes. The control circuit board 2 has a DIP switch 21 with continuous reception mode 211 and off mode 212. The toggle member 41 of the sliding key assembly 4 cooperates with the DIP switch 21. When the sliding key assembly 4 moves to the first or second position, the DIP switch 21 is activated by the toggle member 41, thus switching between different operating modes. Through this structural integration, multi-mode control is achieved with the simple structure of the sliding key assembly 4, improving ease of operation and reliability. The number of conventional buttons and electronic components is reduced, thus reducing size and power consumption, meeting the portability requirements of handheld devices. Simultaneously, the mechanical positioning structure of the sliding key assembly 4 avoids accidental operation, improving reliability, making it user-friendly for blind operation, and providing intuitive operating logic, reducing the user's learning cost.

[0045] Furthermore, the sliding key assembly 4 includes a sliding button 42, a first assembly 43, and a second assembly 44. The sliding button 42 is movably disposed in the slide groove 11 and is located outside the first assembly 43. The first assembly 43 is detachably disposed outside the second assembly 44, and the toggle member 41 is provided on the inner side of the second assembly 44.

[0046] The outer sides of both ends of the first assembly 43 abut against the inner wall of the housing 1. A limiting groove 12 is provided inside the housing 1. The first assembly 43 and the second assembly 44 are movably disposed in the limiting groove 12. The limiting groove 12 has a first notch 121. The first notch 121 is positioned directly opposite the DIP switch 21, so that when the toggle member 41 moves along the first notch 121, it extends to the outside of the first notch 121, thereby toggling the DIP switch 21.

[0047] like Figures 4 to 7 As shown, the sliding key assembly 4 mainly consists of a sliding button 42, a first assembly 43, and a second assembly 44. The sliding button 42 and the first assembly 43 can be integrally formed or directly fixed. Usually, the length of the first assembly 43 is greater than the length of the slide groove 11 to prevent the first assembly 43 from coming out of the limiting groove 12. The length of the limiting groove 12 is greater than the length of the first assembly 43 to facilitate the movement of the first assembly 43 within the limiting groove 12. The first assembly 43 and the second assembly 44 are usually detachable to facilitate the installation of the elastic element 45. The bottom end of the first assembly 43 and the bottom end of the second assembly 44 are basically flush. The top end of the first assembly 43 extends a longer distance than the top end of the second assembly 44. The toggle element 41 is usually integrally formed in the lower part of the inner side of the second assembly 44 to facilitate movement at the first notch 121 to toggle the DIP switch 21.

[0048] Furthermore, the inner side of the first assembly 43 is provided with a hollow first mounting post 431, and the outer side of the second assembly 44 is provided with a hollow second mounting post 441. The second mounting post 441 is inserted into the first mounting post 431 to form an installation space, and an elastic member 45 is provided in the installation space.

[0049] The DIP switch 21 has a key-operated radio mode 213. The control circuit board 2 also has a button 22. A second notch 122 is provided on the limiting groove 12, directly opposite the button 22. A through hole 442 is provided on the second assembly 44. An extension member 432 is provided on the inner side of the first assembly 43, and the extension member 432 is inserted into the through hole 442, such that:

[0050] When the sliding key assembly 4 moves to the third position of the slide groove 11, the toggle member 41 moves to move the DIP switch 21 to the key radio position 213. When the sliding key 42 is pressed by external force, the elastic member 45-spring is in a compressed state, the first assembly 43 moves inward, the extension member 432 extends out of the through hole 442 and presses the button 22 at the second notch 122, and the pickup member 3 is in the pickup enabled state.

[0051] When the sliding button 42 is not pressed, the elastic element 45-spring is in the extended state, the first assembly 43 moves outward, the extension element 432 no longer presses the button 22, and the pickup element 3 is in the pickup off state.

[0052] In this embodiment, the DIP switch 21 also has a button-activated microphone position 213, in which the sliding button 42 needs to be pressed to activate microphone pickup. Specifically, when the sliding button assembly 4 moves to the third position, the DIP switch 21 is switched to the button-activated microphone position 213. At this time, the extension member 432 of the first assembly 43 is exactly at the second notch 122 of the limiting groove 12. Pressing the sliding button 42 will cause the extension member 432 to touch the button 22, thereby putting the microphone 3 into the microphone-activated state, i.e., the button-activated speaking state (the elastic member 45 is in the compressed state). Conversely, when there is no manual operation and the external force disappears, the elastic member 45 will automatically extend, causing the sliding button 42 to pop outward. The extension member 432 will no longer compress the button 22, and the microphone 3 will switch to the microphone-off state. At the same time, the extended elastic member 45 can also increase the feedback feel when the sliding button 42 is pressed again.

[0053] In summary, the presenter can freely switch between the following three modes by controlling a single structure—the sliding button component 4. This increases the user's ease of use in actual use. Mode 1—Pickup On / Pickup Off: The sliding button 42 is at the top position within the slide groove 11. Press the sliding button 42 to activate pickup and release it to stop (similar to the PTT function of a walkie-talkie). Mode 2—Continuous Pickup: The sliding button 42 is slid to the bottom of the slide groove 11, allowing continuous pickup without pressing, suitable for free-flowing presentations. Mode 3—Off: The sliding button 42 is slid to the middle of the slide groove 11, entering the off state.

[0054] Furthermore, the first assembly 43 is provided with two first mounting posts 431 spaced apart, and the second assembly 44 is provided with two second mounting posts 441 spaced apart. Each second mounting post 441 is inserted into the corresponding first mounting post 431 to form the corresponding mounting space. Each mounting space is provided with the elastic member 45.

[0055] In this embodiment, two sets of elastic elements 45 (springs) are used to push out the sliding button 42, resulting in a greater rebound force. When the external force disappears, the sound pickup is returned to the off state. Conversely, a greater external force is required to compress the two sets of elastic elements 45 (springs) to enable sound pickup, which is more accurate and avoids automatically enabling sound pickup when the sliding button 42 is accidentally touched.

[0056] Of course, in other embodiments, only one set of elastic elements 45 and a corresponding set of first mounting posts 431 and second mounting posts 441 may be provided.

[0057] Furthermore, the outer wall of the sliding button 42 is provided with a plurality of protrusions 421. Since the sliding button 42 requires the user to apply a certain force to move it along the slide groove 11 during operation, in order to increase the friction between the user's finger and the sliding button 42, this embodiment provides a plurality of arrayed protrusions 421 on the outer wall of the sliding button 42. On the one hand, it is easier for the user to find the sliding button 42 when operating blindly, and on the other hand, it also reduces the slippage between the finger and the sliding button 42.

[0058] Furthermore, the housing 1 is provided with a first identifier 13, a second identifier 14 and a third identifier 15. The first identifier 13 corresponds one-to-one with the continuous radio mode 211, the second identifier 14 corresponds one-to-one with the off mode 212, and the third identifier 15 corresponds one-to-one with the button radio mode 213.

[0059] The DIP switch 21 is designed with a continuous radio mode 211, an off mode 212, and a button radio mode 213, each corresponding to a different working mode. The housing 1 is provided with a first identifier 13, a second identifier 14, and a third identifier 15 that precisely correspond to the above three modes. Dual positioning is achieved through operation feedback and visual prompts, making it easier for users to judge the current working mode.

[0060] In actual installation, the first indicator 13, the second indicator 14, and the third indicator 15 can also be combined with indicator lights. When a certain position is reached, the indicator light at the corresponding indicator will light up. For example, when the DIP switch 21 is in the continuous radio position 211, the indicator light at the first indicator 13 will light up.

[0061] Furthermore, the slide groove 11 is formed on either side of the housing 1. In this embodiment, the slide groove 11 is located on the upper left or right side of the housing 1, so that the operator's thumb can easily operate the sliding button 42 when holding the audio guide, which is convenient for the user. At this time, the DIP switch 21 and the button 22 are also located on the side of the control circuit board 2 near the slide groove 11.

[0062] Of course, in other embodiments, the slide groove 11 can also be formed on the upper or lower surface of the housing 1, and the corresponding positions of the sliding key assembly 4, the DIP switch 21 and the button 22 can also be adjusted.

[0063] Furthermore, the bottom of the limiting groove 12 is provided with several reinforcing ribs 123. Since the area inside the shell 1 where the limiting groove 12 is provided is a cavity structure, in order to increase the strength of the shell 1, multiple parallel and spaced reinforcing ribs 123 are provided.

[0064] Furthermore, the outer wall of the housing 1 is also provided with a hook 16 for fixing the audio guide. In this embodiment, the hook 16 is usually elongated, so that there is a hook space between the hook 16 and the housing 1, and the thickness of the hook space gradually decreases from top to bottom, which makes it easy to hang the audio guide on other external items (such as clothing), freeing up the hands and making it easy to carry the audio guide.

[0065] Furthermore, the sound pickup element 3 is a microphone. Using a microphone as the sound pickup element 3 offers high sensitivity and wide frequency response, enabling precise capture of environmental sound details and effective separation of target signals. Simultaneously, the microphone in this solution is compact and consumes little power, facilitating integration into the audio guide. In actual installation, the microphone is typically positioned at the upper left or upper right corner of the housing 1 for sound pickup, while an antenna / signal receiver electrically connected to the control circuit board 2 is located at the other corner of the housing 1.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
