Description

Technical Field

[0001] This utility model relates to the field of handheld terminals, and more particularly to PDAs. Background Technology

[0002] In modern PDA devices, the audio module and optical scanning module serve as core functional units, jointly supporting the device's interaction and data acquisition capabilities. Specifically, the audio module provides operational feedback through speakers (such as a successful scan notification tone or an error alarm), thereby enhancing the real-time nature and convenience of user interaction. The optical scanning module, based on photoelectric sensing technology (such as laser scanning or image recognition), is used to capture and decode the optical information of target objects (such as barcodes and QR codes), enabling efficient data reading and transmission.

[0003] However, to achieve device miniaturization, existing technologies generally adopt a vertical stacking layout design, in which the audio module and optical scanning module are spatially stacked and integrated along the longitudinal axis of the device. While this configuration significantly improves the utilization of planar space and supports the high integration of functional units through precise structural optimization (such as modular packaging and compact circuit board design), it exposes inherent physical limitations in three-dimensional space: because vertical stacking requires reserving independent installation space for the audio module and scanning module (including acoustic cavity and optical component installation space), the device must be structurally thickened in the corresponding stacking area, which leads to a local increase in device thickness and reduces the overall thinness and lightness of the product.

An audio module is disposed within the mounting slot; and The scanning module is located in the second mounting position; When the audio module emits sound waves, the sound waves are transmitted in the mounting groove along the first direction, thereby entering the conduction reversal channel and being transmitted along the second direction, and then the sound waves are transmitted out through the sound outlet and the clearance hole.

[0023] Figure 1 and Figure 2 The diagram illustrates a PDA 10 in some embodiments of the game according to this utility model, which is capable of performing a scanning function. The PDA 10 includes a housing 1, a sound guide bracket 2, an audio module 3, and a scanning module 4. The sound guide bracket 2 is disposed within the housing 1, the audio module 3 is disposed on the sound guide bracket 2, and the scanning module 4 is located on the sound guide bracket 2.

[0024] It should be noted that the housing 1 serves to install and house the remaining components. The sound guide bracket 2 serves two purposes: guiding sound wave transmission and mounting the audio module 3. The audio module 3 is used to emit sound waves during operation. The scanning module 4 is used to perform the scanning function.

[0025] like Figures 1 to 8 As shown, the housing 1 has a clearance hole 11. The sound guide bracket 2 has a first mounting position 211 and a second mounting position 221. The first mounting position 211 has a mounting groove 2111 along the first direction D1. The groove wall of the mounting groove 2111 has a conduction reversing channel 2211 along the second direction D2. The inner wall of the conduction reversing channel 2211 has a sound outlet hole 2222. The sound outlet hole 2222 is aligned with the clearance hole 11. The first mounting position 211 and the second mounting position 221 are spaced apart or partially overlapped, and the first direction D1 and the second direction D2 intersect.

[0026] The audio module 3 is disposed in the mounting slot 2111. The scanning module 4 is located in the second mounting position 221. When the audio module 3 emits sound waves, the sound waves are transmitted in the mounting slot 2111 along the first direction D1, thereby the sound waves enter the conduction reversal channel and are transmitted along the second direction D2, and then the sound waves are transmitted out through the sound outlet 2222 and the clearance hole 11.

[0027] Understandably, the mounting slot 2111 is used to accommodate the audio module 3 and guide the sound waves to propagate in a straight line along the first direction D1, forming an initial sound wave channel. The conduction reversing channel 2211 is used to change the direction of sound wave propagation, redirecting the sound waves propagating along the first direction D1 to the second direction D2, thus realizing the reversing function of the sound wave path. The sound outlet 2222 is used to export the sound waves within the conduction reversing channel 2211 and align them with the clearance hole 11 to ensure smooth sound wave output. The clearance hole 11 is used to allow sound waves to travel from inside the housing 1 to the external environment, realizing the external release of sound.

[0028] It should be noted that the partial overlap between the first mounting position 211 and the second mounting position 221 includes at least the following implementation methods: First, the edge of the first mounting position 211 contacts the edge of the second mounting position 221; second, a portion of the first mounting position 211 overlaps with a portion of the second mounting position 221, wherein the first mounting position 211 does not completely encompass the second mounting position 221, and the second mounting position 221 does not completely encompass the first mounting position 211. Furthermore, the spacing between the first mounting position 211 and the second mounting position 221 refers to a gap between the edges of the first mounting position 211 and the edges of the second mounting position 221.

[0029] It should also be noted that by setting the longitudinal offset of the sound guide bracket 2 and the sound wave transmission path (installation slot 2111 and transmission reversal channel 2211), this utility model can effectively avoid the installation space conflict caused by the longitudinal stacking of the audio module 3 and the scanning module 4 while ensuring the smooth transmission of sound waves, thereby avoiding excessive local thickness of the product and significantly improving the overall thinness of the PDA10.

[0030] Furthermore, the longitudinal direction referred to in this invention refers to the thickness direction of the product. Therefore, the longitudinal misalignment can reduce the increased thickness of the product required at that location to accommodate component installation space.

[0031] like Figure 8 As shown, in some embodiments of PDA10, the first direction D1 intersects the second direction D2 at a right angle.

[0032] Understandably, D1 is perpendicular to D2, which can force the sound wave to turn 90° within the conduction reversal channel 2211, achieving efficient transmission of the longitudinal sound wave to the horizontal direction through the shortest path and avoiding sound wave scattering loss.

[0033] It should be noted that by using the physical constraint of right-angle turning, the audio module 3 and the scanning module 4 can be vertically staggered to optimize the sound wave path with minimal space cost. This greatly reduces the thickness redundancy caused by module stacking, improves the thinness of the PDA10, and ensures the efficiency of sound wave transmission.

[0034] like Figures 1 to 8 As shown, in some embodiments of PDA10, a panel 12 is provided on the housing 1, and a clearance hole 11 is located on the panel 12; The sound guide bracket 2 includes a mounting part 21 and a reversing part 22. The reversing part 22 is connected to the mounting part 21. Both the mounting part 21 and the reversing part 22 are connected to the panel 12. The first mounting position 211 is located on the mounting part 21, and the groove of the mounting slot 2111 is exposed on the surface of the mounting part 21 away from the panel 12. The second mounting position 221 is located on the reversing part 22, and the conduction reversing channel 2211 is located inside the reversing part 22. The scanning module 4 is located on the surface of the reversing part 22 away from the panel 12.

[0035] Understandably, panel 12 can provide a mounting reference surface for sound guide bracket 2 on the one hand, and can also enable unobstructed release of sound waves from the inside to the outside through clearance hole 11 on the other hand.

[0036] The exposed slot of the mounting section 21 allows the audio module 3 to be quickly positioned and installed by following the slot outline, ensuring that sound waves can be transmitted into the mounting slot 2111, reducing interference from the transmission medium, and ensuring that the sound waves are transmitted along the first direction D1. The conduction reversing channel 2211 is located on the physical structure of the reversing section 22, and can effectively isolate external noise interference, maintaining the purity of the reversing sound waves.

[0037] Independent mounting surface of scanning module 4: An independent bearing area is formed by using the surface of the commutator 22 that is far away from the panel 12 to avoid physical interference with the sound wave transmission path of audio module 3.

[0038] like Figures 3 to 8 As shown, in some embodiments of PDA10, the commutation unit 22 has a recessed groove 222 on the surface facing the panel 12, the sound outlet 2222 is located at the bottom of the recessed groove 222, and the conduction commutation channel 2211 is connected to the recessed groove 222 through the sound outlet 2222.

[0039] Understandably, the recess 222 can be used to install components, such as parts that prevent contaminants from entering the conduction reversing channel 2211. The sound outlet 2222 is located at the bottom of the recess 222, ensuring that sound waves are vertically introduced into the recess 222 from the conduction reversing channel 2211, achieving directional convergence of sound waves, and further guiding the converged sound waves to the recess outlet for discharge.

[0040] like Figures 1 to 8 As shown, in some embodiments of PDA10, PDA1010 also includes a protective member 5. The protective member 5 has several through holes 511. The protective member 5 is disposed in the relief groove 222. The protective member 5 blocks the relief hole 11. Each through hole 511 is exposed in the relief hole 11, and each through hole 511 is connected to the sound outlet hole 2222. The through hole 511 is used to receive the sound waves transmitted from the sound outlet 2222 and further guide the sound waves through the panel 12.

[0041] Understandably, the protective component 5 serves to physically isolate external dust and liquid from entering the clearance hole 11, while maintaining sound wave penetration through the through hole 511 to ensure that sound waves can be transmitted to the outside. The through hole 511 can guide the sound waves that converge in the clearance groove 222 in segments, reduce sound pressure loss, and ensure that sound waves penetrate the panel 12 evenly.

[0042] Thus, through the content of this embodiment, while achieving efficient sound wave extraction, the physical isolation design of the protective component 5 significantly improves the environmental adaptability and durability of the PDA10.

[0043] like Figure 6 and Figure 7As shown, in some embodiments of PDA10, each through hole 511 is spaced apart along the length extension direction of the protective member 5.

[0044] Understandably, the spacing of each through-hole 511 can disperse the sound wave output pressure, prevent sound waves from superimposing and interfering within the clearance hole 11, and maintain sound clarity. In this way, by dispersing and exporting sound waves through multiple channels, the sound field distribution is optimized, audio distortion is eliminated, and the user's listening experience is improved.

[0045] As shown in the figure As shown, in some embodiments of PDA10, the protective component 5 includes a fixing plate 51 and an annular flange 52. The annular flange 52 is disposed on the fixing plate 51, and each through hole 511 is located inside the annular flange 52. The fixing plate 51 is connected to the panel 12, and the fixing plate 51 is provided with a relief groove 222. The outer periphery of the annular flange 52 abuts against the wall of the relief hole 11.

[0046] Understandably, the fixing plate 51 provides a mounting base for the protective component 5 and the panel 12, ensuring structural stability. The fixing plate 51 and the panel 12 can be connected by adhesive bonding. The annular flange 52 forms a sealing structure by correspondingly engaging its outer periphery with the wall of the clearance hole 11, blocking the penetration of contaminants. The through hole 511 is located within the annular flange 52, using the space enclosed by the flange to constrain the sound wave diffusion path and enhance the directional penetration capability of the sound waves.

[0047] It should be noted that the sealing and holding design of the annular flange 52 achieves triple protection (dustproof, waterproof, and shockproof) in a minimal space, while maintaining the efficiency of sound wave guidance.

[0048] like Figures 3 to 8 As shown, in some embodiments of PDA10, the audio module 3 includes a speaker, which is disposed in the slot of the mounting groove 2111 and faces the bottom of the mounting groove 2111.

[0049] Understandably, the speaker is oriented towards the bottom of the mounting groove 2111 so that the direction of sound wave emission is completely coincident with the extension direction of the mounting groove 2111 (first direction D1), maximizing the use of the groove wall to guide the sound wave transmission, ensuring that the sound wave can fully enter the conduction reversal channel 2211 on the groove wall of the mounting groove 2111, and avoiding sound wave loss.

[0050] like Figure 6 As shown, in some embodiments of PDA10, the width W2 of the conduction reversing channel 2211 is smaller than the groove width W1 of the mounting groove 2111.

[0051] Understandably, since W2 is less than W1, the sound waves are concentrated after entering the conduction reversing channel 2211, which to a certain extent compresses the sound waves, enhances the energy density of the sound waves entering the conduction reversing channel 2211, and ensures the loudness stability of the sound waves when they are output through the avoidance hole 11.

[0052] like Figure 3 , Figure 5 and Figure 8 As shown, in some embodiments of PDA10, the scanning module 4 includes a fixed housing 41, a mounting base 42 and at least one scanning head 43. The fixed housing 41 is disposed inside the housing 1 and abuts against the second mounting position 221. The mounting base 42 is disposed inside the fixed housing 41, and each scanning head 43 is disposed on the mounting base 42.

[0053] Understandably, the fixing housing 41 abuts against the second mounting position 221, allowing for longitudinal misalignment between the fixing housing 41 and the audio module 3. The mounting base 42 is used to mount the scanning head 43. The scanning head 43 is used for scanning and recognition.

[0054] It should be noted that the scanning head 43 can be configured as one or more. Multiple scanning heads 43 can be configured to include various scanning heads with different scanning functions or scanning targets in the prior art.

[0055] The following are the beneficial effects of implementing this utility model: This utility model relates to a PDA in which the first and second mounting positions of the sound guide bracket are longitudinally staggered with intervals or partial overlap, allowing the audio module and the scanning module to be longitudinally staggered, avoiding the need for their respective mounting spaces to be located in the same longitudinal direction. During operation, sound waves are transmitted along a first direction within the mounting groove, and further redirected to a second direction (such as the horizontal direction) through a conduction reversal channel on the groove wall, thus ensuring smooth sound wave transmission even with the longitudinal staggered arrangement.

[0056] Thus, this invention solves the problem of localized thickening of the product caused by the vertical stacking of the audio module and the scanning module in the prior art, while ensuring the smooth transmission of sound waves, thereby improving the thinness and lightness of the product.

Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the modules in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.
