Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-10 A detachable portable audio transmitter 101 for use with a handle 100 includes a housing 102 housed in the battery compartment of a main device and an outer cover 105 covering the battery compartment of the main device, wherein the outer cover 105 is detachably fixed to the battery compartment of the main device.

[0036] The housing 102 is provided with a battery for powering the main device and a control module electrically connected to the battery. The control module is used to convert the target analog audio signal received by the signal plug 110 into a digital audio signal and can wirelessly transmit the digital audio signal.

[0037] The side of the housing 102 is provided with an electrode plate 108 that is electrically connected to the battery, and the electrode plate 108 is electrically connected to the power supply port in the battery compartment of the main device.

[0038] The control module is powered on and connected to a signal plug 110 extending from the housing 102 and the outer cover 105. The signal plug 110 is used to connect to the signal output port 111 on the main device.

[0039] like Figure 1 As shown, the detachable portable audio transmitter 101 of this utility model systematically solves the user experience problems caused by poor battery compatibility, bulky external devices and insufficient interface stability in the prior art through innovative structural design and functional integration.

[0040] Specifically, this utility model adopts an embedded modular design for the battery compartment, integrating the power supply and audio transmission functions into the original battery space of the handle 100, avoiding the drawbacks of traditional external transmitters that cause the grip area to protrude and affect the operating feel due to occupying the space on the back of the handle 100.

[0041] With a standardized battery compartment structure compatible with mainstream lithium battery specifications, the built-in intelligent control module can monitor battery voltage, current and temperature parameters in real time. Combined with an adaptive power management algorithm, it can dynamically adjust the output power, effectively preventing equipment damage caused by battery overload, aging or incompatibility. At the same time, it supports users to quickly replace standardized battery cells, completely solving the pain points of lithium battery aging that cannot be replaced and sudden reduction in battery life in existing technologies.

[0042] The control module and signal plug 110 are connected by a flexible cable and integrated into the battery compartment. The original space layout of the battery compartment is used to achieve functional superposition. This completely avoids the problem of space encroachment on the grip area caused by the protruding installation of traditional external transmitters. It keeps the back of the handle 100 flat, significantly improves operating comfort, and avoids the risk of deformation of the external transmitter interface caused by external impact of traditional rigid plugs.

[0043] In addition, the snap-fit ​​structure of the plug and the outer cover 105 can ensure consistent insertion depth. Combined with the self-adjusting contact mechanism of the elastic electrode 108 and the power supply port in the main device battery compartment, a stable signal path is established simultaneously when the signal plug 110 is inserted into the signal interface of the handle 100, achieving a double physical locking effect and reducing the probability of interface loosening compared to traditional external transmitters.

[0044] This utility model's detachable portable audio transmitter 101 features a split design that integrates the transmitter module into the battery compartment. While retaining the original power supply function of the handle 100, it utilizes the battery compartment space for modular installation, effectively avoiding the discomfort caused by an external transmitter occupying operating space. The direct contact structure between the electrode plate 108 and the power supply port, combined with the detachable outer cover, ensures power supply stability while enabling quick battery replacement. The signal plug 110, which penetrates the outer cover of the housing 102, is connected to the signal output port 111 on the main device via a wire connection, significantly reducing the risk of the external transmitter's power supply and audio interface becoming loose due to hand friction or device shaking, thereby ensuring the long-term stability of audio signal transmission.

[0045] In this embodiment of the present invention, the front side of the housing 102 is provided with a first receiving groove 112, and the outer cover 105 is provided with a through second receiving groove 113 that is aligned and cooperates with the first receiving groove 112. The first receiving groove 112 and the second receiving groove 113 cooperate to form a receiving chamber 114, and the signal plug 110 is housed in the receiving chamber 114.

[0046] like Figure 1 As shown, through the alignment and nesting design of the first accommodating slot 112 and the second accommodating slot 113, the housing 102 and the outer cover 105 are combined to form an accommodating chamber 114, and the signal plug 110 is built into the battery compartment space, realizing a highly integrated layout of the signal transmission components.

[0047] This structure utilizes a space reuse mechanism to store the signal plug 110 in the depth of the battery compartment without increasing the volume of the handle 100. This keeps the outer surface of the outer cover 105 flush with the housing 102 of the handle 100, completely eliminating the interference of the protruding structure of traditional external transmitters on the grip feel.

[0048] The circuitous routing design of the flexible cable at the base of the plug avoids poor contact caused by rigid collision between the signal plug 110 and the handle 100 interface.

[0049] In this embodiment of the present invention, the inner side of the outer cover 105 is provided with a first buckle assembly that engages with the upper end of the battery compartment of the main device and a second buckle assembly that engages with the lower end of the battery compartment of the main device.

[0050] like Figure 2 As shown, this utility model embodiment systematically optimizes the mechanical coupling stability and maintenance convenience of the split transmitter and the battery compartment of the handle 100 by setting an upper and lower double buckle linkage locking structure on the inner side of the outer cover 105.

[0051] The first latching assembly provides continuous clamping force to the upper end of the battery compartment, ensuring that the upper end is locked without shaking; the second latching assembly forms a torque balance with the upper end latch at the lower end of the battery compartment, effectively suppressing the deformation of the outer cover 105 in the thumb pressing area when the handle 100 is held.

[0052] The asymmetric mechanical distribution design of the dual-buckle assembly can also counteract the lateral shear force generated by the high-frequency vibration of the handle 100. Combined with the silicone shock-absorbing layer set on the buckle contact surface, the impact energy absorption rate between the outer cover 105 and the battery compartment is improved. This maintains the tight fit of the split structure and avoids the problem of gap expansion caused by buckle wear after long-term use, significantly extending the service life of the device.

[0053] In this embodiment of the utility model, the first buckle assembly includes first buckle members 116 symmetrically fixed on the upper end of the outer cover 105, and the first buckle members 116 are vertically downwardly arranged on the upper end of the outer cover 105.

[0054] like Figure 2 As shown, this utility model embodiment constructs a high-precision guiding and balanced force mechanical locking system by symmetrically setting vertically downward first buckle members 116 on the upper end of the outer cover 105. The symmetrically distributed first buckle members 116 are arranged in a mirror image along the central axis of the upper end of the outer cover 105. The end of its vertically downward buckle arm is provided with a wedge-shaped guide head that matches the inverted trapezoidal slot pre-set at the upper end of the battery compartment. During installation, self-alignment calibration is achieved by sliding in synchronously on both sides, eliminating the assembly stress concentration caused by the unilateral buckle misalignment.

[0055] The symmetrical layout of the left and right latches ensures that the locking force is evenly distributed on both sides of the upper end of the battery compartment. Combined with the silicone damping layer on the inner side of the latch arm to absorb high-frequency vibration energy, this improves the lateral displacement suppression rate compared to the traditional single-sided latch solution. It effectively avoids latch fatigue fracture caused by uneven force, significantly improving the safety of maintenance operations and the durability of the equipment.

[0056] In this embodiment of the present invention, the second buckle assembly includes a plurality of second buckle members 117 fixed at equal intervals at the lower end of the outer cover 105, and the second buckle members 117 are vertically downward at the lower end of the outer cover 105.

[0057] like Figure 2 As shown, this utility model embodiment constructs a high-density distributed mechanical bearing system by fixing multiple vertically downward second fasteners 117 at equal intervals at the lower end of the outer cover 105. The multiple second fasteners 117 are arranged at equal intervals along the lower edge of the outer cover 105. Their vertically downward rigid tenons and the stepped slots corresponding to the lower end of the battery compartment form a multi-level interlocking structure. The synchronous elastic deformation unlocking is achieved by utilizing the characteristic of multiple fasteners being subjected to force at equal intervals, thus avoiding local fastener overload breakage.

[0058] In addition, the root of the second buckle 117 and the main body of the outer cover 105 are integrally formed with gradient reinforcing ribs, forming a stress diffusion zone at the buckle base. This concentrates the bending fatigue from repeated disassembly and reassembly in the preset elastic hinge area, which improves the cycle service life compared to the traditional direct-connection buckle. At the same time, the waterproof sealing strip added to the edge of the outer cover 105 expands under pressure when the buckle is locked, achieving dustproof and waterproof performance and comprehensively enhancing the environmental adaptability of the equipment.

[0059] In this embodiment of the utility model, the control module is provided with a power interface 118 extending out of the housing 102, and the outer cover 105 is provided with a power slot 119 that is plugged into and cooperates with the power interface 118.

[0060] like Figure 3 As shown, this utility model embodiment achieves modular reconfiguration of the power supply system and improved operational safety through the plug-in separation design of the power interface 118 of the control module and the power slot 119 of the outer cover 105. The power interface 118 adopts a vertical layout and extends from the side of the housing 102.

[0061] In this embodiment of the present invention, the front side of the housing 102 is provided with an outwardly protruding first protrusion 120, and a first receiving groove 112 is provided on the first protrusion 120. The first protrusion 120 is engaged in the second receiving groove 113.

[0062] like Figure 4 As shown, this utility model embodiment achieves structural reinforcement and spatial adaptation optimization of the signal plug 110 receiving chamber 114 through the nested snap-fit ​​design of the first protrusion 120 on the front of the housing 102 and the second receiving groove 113 of the outer cover 105. The first protrusion 120 extends with an outward protruding irregular geometric structure, and its outer contour forms an interference fit interface with the inner wall of the second receiving groove 113. During assembly, the guide slope of the side wall of the protrusion 120 and the chamfer of the groove edge of the outer cover 105 guide self-alignment to ensure that the housing 102 and the outer cover 105 form a zero-gap receiving chamber 114 after being combined.

[0063] The first protrusion 120 adopts a gradient stiffness design. The thickened area at the root is integrally formed with the main body of the shell 102 to improve the bending strength. The thin-walled area at the front end is embedded with elastic buffer material, which absorbs assembly stress through compression deformation during snapping and avoids cracking of plastic parts caused by rigid collision.

[0064] Through the highly customized design of the first protrusion 120, a layered spatial layout is formed within the limited depth of the battery compartment, so that the signal plug 110 cable can be stored along the first accommodating groove 112 preset on the first protrusion 120.

[0065] In this embodiment of the utility model, the upper end of the outer cover 105 is provided with a snap-fit ​​groove 121 for snapping the outer cover 105.

[0066] like Figure 6 As shown, this utility model embodiment achieves ergonomic optimization and mechanical reliability improvement in the disassembly operation of the outer cover 105 by setting a dedicated latching groove 121 on the upper end of the outer cover 105. The latching groove 121 adopts a concave arc contour design, and its depth matches the curvature of the adult thumb pad. The axis of the latching groove 121 is precisely aligned with the unlocking direction of the first latching component.

[0067] In this embodiment of the utility model, a first mounting groove 122 is provided on the housing 102, and a second mounting groove 123 is provided on the outer cover 105 that passes through and is aligned with the switch mounting groove. A switch 124 that is electrically connected to the control module is fixed in the first mounting groove 122.

[0068] like Figure 1 As shown, this utility model embodiment achieves high-precision positioning and comprehensive improvement of operational reliability of switch 124 through the double-groove alignment and installation structure of housing 102 and outer cover 105. The first mounting groove 122 adopts a stepped recessed groove design, with a metal reinforcing skeleton pre-embedded at the bottom and integrally injection molded with the internal structure of housing 102, ensuring improved deformation resistance of the mounting base of switch 124.

[0069] The second mounting groove 123 forms a through guide channel at the corresponding position of the outer cover 105. The inner wall of the second mounting groove 123 is provided with a chamfered guide surface and a sealing flange at the edge of the first mounting groove 122 to form a labyrinth waterproof structure. After the switch button passes through the second mounting groove 123, it achieves dustproof and waterproof by compression through the silicone sealing ring between the flange and the chamfered surface.

[0070] The switch 124 is electrically connected to the control module, and the trigger rod of the switch button extends to the surface of the outer cover 105.

[0071] In this embodiment of the utility model, the outer cover 105 is bent into an L-shaped structure 125;

[0072] like Figure 5 As shown, this utility model embodiment achieves optimized spatial layout and enhanced mechanical performance by bending the outer cover 105 into an L-shaped structure 125. The upper horizontal section of the L-shaped bending structure is closely fitted with the opening plane of the battery compartment, and the distributed snap-fit ​​assembly on its inner side forms a multi-directional locking with the shell 102.

[0073] Meanwhile, the L-shaped corner adopts a gradient arc transition design, and its radius of curvature matches the physiological curve of the palm and the tiger's mouth, eliminating the uncomfortable feeling of traditional right-angled edges when holding it.

[0074] In addition, the lever fulcrum effect formed by the L-shaped structure 125 when disassembling the outer cover 105 allows the user to overcome the locking force of the buckle by applying only a small force at the end of the vertical section. This improves the disassembly efficiency compared to traditional flat cover plates. Furthermore, the elastic recovery characteristics of the L-shaped structure 125 during disassembly can automatically correct the deformation of the cover, ensuring the accuracy of repeated assembly and significantly extending the service life of the equipment.

[0075] In one embodiment, the main body of the housing 102 and the outer cover 105 is made of lightweight material (such as ABS plastic or aluminum alloy), and the shape is designed to fit closely to the battery compartment of the XBOX controller 100, so that the operation comfort of the controller 100 will not be affected after installation.

[0076] In one embodiment, the housing is provided with a sliding cover storage mechanism that can accommodate a 3.5mm audio adapter.

[0077] In one embodiment, the control module has a built-in high-performance Bluetooth audio chip (supporting Bluetooth 5.4) to enable wireless transmission of audio signals. When using 2.4G mode, the latency is less than 30ms, making it compatible with wireless headphones currently on the market.

[0078] In one embodiment, the battery device includes a built-in rechargeable lithium battery (capacity 2000-3000mAh) that supports up to 30 hours of continuous use.

[0079] In one embodiment, the power interface 118 includes a TYPE-C interface, which enables fast charging and supports simultaneous charging and use.

[0080] In one embodiment, the outer cover 105 is equipped with LED indicator lights to display power status and connection status.

[0081] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
