[0002] With the diversification of modern entertainment, karaoke has become an important leisure activity in people's daily lives. Karaoke devices, a popular home karaoke equipment in recent years, have gained widespread popularity due to their portability and ease of use. Traditional karaoke devices typically integrate a microphone and speaker, allowing users to synchronize with various playback devices via Bluetooth or wireless connection for impromptu singing.

[0003] However, existing karaoke devices have some limitations in design and use. First, the sound-generating unit (i.e., speaker) and microphone of most karaoke devices are fixed as a single unit, meaning that when the speaker malfunctions or the user wants to upgrade the sound quality, the entire device often needs to be replaced. Second, the fixed structural design restricts the user's freedom to combine the device's appearance and functional modules, reducing the product's flexibility and personalization.

[0004] Therefore, improvements are needed to the existing karaoke device to solve the problem of its non-removable sound source.

[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0043] This invention provides a replaceable sound-emitting karaoke device, suitable for applications where singing and playback are performed simultaneously. It effectively solves the problem that the sound-emitting body of existing karaoke devices cannot be disassembled.

[0044] See Figure 1 The replaceable sound source karaoke device provided in this embodiment includes a microphone 1, a replaceable sound source 2, and a pluggable ribbon cable.

[0045] The microphone 1 includes a handheld housing 101 and a pickup unit installed inside the handheld housing 101; the replaceable sound source 2 includes a speaker housing 201 that is rotatably snapped onto the bottom of the handheld housing 101 and a sound source installed inside the speaker housing 201; one end of the pluggable ribbon cable is plugged into the pickup unit and the other end is plugged into the sound source.

[0046] The replaceable sound generator karaoke device provided in this embodiment can be used normally by rotating the speaker housing 201 clockwise and attaching it to the bottom of the handheld housing 101 (the pickup unit collects the user's singing voice, and the sound generator plays the sound). When it is necessary to disassemble or replace the speaker 202, simply twist the speaker housing 201 in the opposite direction to remove the replaceable sound generator 2, and then unplug the connector cable to completely detach the replaceable sound generator 2 from the microphone 1.

[0047] Therefore, the replaceable sound-generating karaoke device provided by this utility model can effectively solve the problem that the sound-generating body of existing karaoke devices cannot be disassembled.

[0048] In this embodiment, see Figure 2 and Figure 3 The speaker housing 201 is provided with an upward-facing receiving groove 2011. The sound-generating unit includes a speaker 202 located in the receiving groove 2011 and a speaker cover plate 203 located above the speaker 202 and covering the opening of the receiving groove 2011.

[0049] Optionally, the bottom surface of the speaker housing 201 is provided with a plurality of sound outlet holes 2012. The speaker cover plate 203 covers the opening of the receiving groove 2011 to form a sealed chamber, thereby improving the sound quality of the speaker 202. By placing the sound outlet holes 2012 on the bottom surface of the speaker housing, the interference between the speaker 202 and the pickup can be minimized, thereby suppressing the occurrence of feedback.

[0050] Furthermore, the top surface of the horn cover plate 203 has an upwardly protruding C-shaped boss 2031, and the circumferential surface of the C-shaped boss 2031 is provided with a plurality of radially outwardly protruding limiting bosses 2032.

[0051] Accordingly, see Figure 4 The bottom of the handheld housing 101 is provided with an L-shaped stop 1011 corresponding to the position of each limiting boss 2032. The L-shaped stop 1011 forms a limiting groove 1012 for the limiting boss 2032 to enter and exit. A positioning block 2033 protrudes downward from the bottom surface of the limiting boss 2032, and a positioning slot 1013 is provided on the groove wall of the limiting groove 1012 corresponding to the position of the positioning block 2033.

[0052] When the replaceable sound source 2 is turned clockwise, the L-shaped stop 1011 enters the corresponding limiting groove 1012, and the positioning block 2033 fits into the positioning slot 1013, thus achieving relative positioning between the replaceable sound source 2 and the microphone 1. When it is necessary to disassemble the replaceable sound source 2, first apply a little force and turn the replaceable sound source 2 counterclockwise, so that the positioning block 2033 disengages from the positioning slot 1013. Then continue to turn the replaceable sound source 2 counterclockwise, so that the limiting boss 2032 disengages from the limiting groove 1012, and the replaceable sound source 2 can be removed.

[0053] In this embodiment, the sound-generating unit further includes a charging interface 204 installed on the top surface of the speaker cover 203; the charging interface 204 and the speaker 202 are both electrically connected to the pickup unit via plug-in cables.

[0054] Optionally, the speaker cover 203 is provided with a wire passage hole 2034, through which the plug-in cable electrically connecting the speaker 202 and the pickup unit passes. Further, the wire passage hole 2034 is provided with sealant for sealing the wire passage hole 2034.

[0055] This isolates the upper and lower spaces of the speaker cover 203, preventing feedback between the pickup unit and the sound-emitting unit due to poor sealing of the wire hole 2034.

[0056] In this embodiment, the pickup unit includes a microphone, a motherboard electrically connected to the microphone, and a lithium battery electrically connected to the motherboard. Specifically, the charging interface 204 and the speaker 202 are both electrically connected to the motherboard via pluggable ribbon cables.

[0057] The microphone 1 is relatively large. Placing the lithium battery in the microphone 1 location allows for the use of a larger lithium battery, thereby improving the product's battery life.

[0058] In summary, the replaceable sound-generating karaoke device provided in this embodiment has the following advantages:

[0059] ① Replaceability: This utility model, through the design of a rotatable snap-fit ​​speaker housing 201 and a pluggable ribbon cable, allows the sound generator to be easily disassembled and replaced, solving the problem of the non-removable sound generator of existing karaoke devices and improving the maintainability and service life of the product.

[0060] ② Suppressing feedback: By setting a sound hole 2012 on the bottom surface of the speaker housing 201, the interference between the speaker 202 and the pickup is reduced, effectively suppressing feedback and improving sound quality;

[0061] ③ Accurate positioning: The design of the C-shaped boss 2031 and the L-shaped stop 1011, as well as the cooperation of the positioning block 2033 and the positioning slot 1013, ensure the precise relative positioning between the sound-emitting body and the microphone 1, thus guaranteeing the stability and durability of the product.

[0062] ④ Good sealing performance: The wire hole 2034 and sealant design on the speaker cover plate 203 effectively isolate the upper and lower spaces, preventing the howling problem caused by poor sealing.

[0063] ⑤ Improve battery life: By placing the lithium battery at microphone 1, and utilizing the larger size of microphone 1, a larger lithium battery can be used, thereby improving the product's battery life.
