[0042] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0044] In some embodiments, such as Figures 1-3 As shown, this utility model proposes a wireless lavalier guide, including a wireless guide 10 and a clip 20 located on the outer side wall of the wireless guide 10; the outer side wall of the wireless guide 10 is provided with a connector 101 protruding outward, the top of the connector 101 is provided with a first protrusion 1011, and the outer surface of the first protrusion 1011 is covered with a first magnetic body 1012.

[0045] The clip 20 is provided with a matching first through hole 201 corresponding to the connector 101. The inner sidewall of the first through hole 201 extends inward in the circumferential direction to form an annular locking block 2011. The first protrusion 1011 extends into the first through hole 201 and forms a pin connection with the annular locking block 2011 through a clearance fit. That is, the first protrusion 1011 can rotate relative to the annular locking block 2011 around the axis of the connector 101.

[0046] The contact surface between the annular block 2011 and the first protrusion 1011 is covered with a second magnetic body 2012, and the polarity of the contact surface between the second magnetic body 2012 and the first magnetic body 1012 is opposite.

[0047] It is understood that the shapes of the connector 101 and the first protrusion 1011 proposed in this embodiment are preferably cylindrical, and the outer diameter of the first protrusion 1011 is smaller than the outer diameter of the connector 101; the annular locking block 2011 extends continuously along the circumferential direction of the inner sidewall of the first through hole 201 and protrudes radially inward to form an integral flange structure, and the annular locking block 2011 is horizontally arranged, and a limiting through hole is formed in the middle of the annular locking block 2011 to facilitate the insertion of the first protrusion 1011, so that a clearance fit is formed between the first protrusion 1011 and the limiting through hole.

[0048] Thus, when it is necessary to assemble the wireless guide device 10 and the clip 20 together, the connector 101 must first be inserted into the first through hole 201 of the clip 20, and then the first protrusion 1011 and the annular locking block 2011 are connected by a pin through a clearance fit, so that the clip 20 can rotate 360° relative to the wireless guide device 10. At the same time, the first magnetic body 1012 of the first protrusion 1011 can attract the second magnetic body 2012 of the annular locking block 2011, so as to prevent the clip 20 from falling off the wireless guide device 10.

[0049] Therefore, the first protrusion 1011 and the annular locking block 2011 of this utility model are connected by a pin through a gap fit, which ensures that the clip 20 rotates 360° relative to the wireless guide 10, thereby flexibly adjusting the rotation angle of the clip 20 relative to the wireless guide 10. When the clip 20 rotates to the ideal angle relative to the wireless guide 10, the first protrusion 1011 and the annular locking block 2011 are then magnetically locked by the first magnetic body 1012 and the second magnetic body 2012 that attract each other.

[0050] In some embodiments, such as Figure 1 As shown, this embodiment provides an assembly structure for the clip 20:

[0051] The clamp 20 includes a first clamping arm 202, a second clamping arm 203, and a torsion spring 204; wherein the first clamping arm 202 and the second clamping arm 203 are symmetrically connected by a pivot pin 205, and the pivot pin 205 passes through the middle of the first clamping arm 202 and the second clamping arm 203; the middle part of the torsion spring 204 is sleeved on the pivot pin 205, and the two ends of the torsion spring 204 respectively abut against the opposite side walls of the first clamping arm 202 and the second clamping arm 203.

[0052] The second clamping arm 203 has a first through hole 201 at its upper part, and the side wall of the second clamping arm 203 facing away from the first clamping arm 202 is in close contact with the corresponding outer side wall of the wireless guide device 10; the first clamping arm 202 has a second through hole 206 corresponding to the first through hole 201. The ends of the first and second clamping arms 202 and 203 with through holes are pressing ends, and the other ends away from the through holes are clamping ends. The pressing end of the first clamping arm 202 and the outer side wall facing away from the second clamping arm 203 have multiple first anti-slip protrusions to prevent the guide's fingers from slipping off the pressing end of the first clamping arm 202; the clamping ends of the first and second clamping arms 202 and the clamping surfaces opposite each other both have multiple second anti-slip protrusions to increase the friction of the clamping end of the clip 20 when clamping, ensuring that the clip 20 can be more stably clamped to the guide's collar.

[0053] When the presenter presses the pressing end of the first clamping arm 202, the first clamping arm 202 presses down on the second clamping arm 203 around the pivot pin 205, the torsion spring 204 undergoes elastic deformation, and the clamping ends of the first clamping arm 202 and the second clamping arm 203 open relative to each other, thus completing the opening of the clamp 20.

[0054] In some embodiments, such as Figure 2 As shown, the outer side wall of the connector 101 extends outward along its axial direction with at least one second protrusion 1013;

[0055] The inner sidewall of the first through hole 201 is provided with a plurality of first slots 2013 in the circumferential direction corresponding to the second protrusion 1013; any second protrusion 1013 can be matched and engaged with the first slot 2013.

[0056] It should be noted that the cross-section of the second protrusion 1013 is preferably trapezoidal or semi-circular, and the second protrusion 1013 proposed in this embodiment can undergo elastic deformation.

[0057] In this way, when the clip 20 rotates relative to the wireless guide 10, the second protrusion 1013 will disengage from the current first slot 2013. After the clip 20 rotates to the ideal angle relative to the wireless guide 10, the second protrusion 1013 will engage with the corresponding first slot 2013 again, further improving the stability between the connector 101 and the first through hole 201 and reducing the possibility that the clip 20 will rotate again due to external vibration after it has rotated to the ideal angle relative to the wireless guide 10.

[0058] In other embodiments, to further improve the stability between the connector 101 and the first through hole 201, such as... Figure 4 As shown, the outer sidewall of the connector 101 is provided with at least one second protrusion group at intervals along its axial direction, and each second protrusion group includes at least two second protrusions 1013 distributed circumferentially at intervals along the outer sidewall of the connector 101.

[0059] The inner sidewall of the first through hole 201 is provided with a plurality of first slots 2013 in the circumferential direction corresponding to the second protrusion 1013, and any second protrusion 1013 can be matched and engaged with the first slot 2013.

[0060] It should be noted that this embodiment uses the example of two second protrusion groups spaced apart along the axial direction on the outer side wall of the connector 101. Of course, the corresponding second protrusions 1013 between the two second protrusion groups are all on the same vertical line; and the second protrusions 1013 proposed in this embodiment can undergo elastic deformation.

[0061] In other embodiments, to further improve the stability between the connector 101 and the first through hole 201, such as... Figures 5-6As shown, the outer side wall of the connector 101 extends outward along its axial direction with at least one second protrusion 1013, and the outer side wall of the second protrusion 1013 is covered with a third magnetic body 1014.

[0062] The inner wall of the first through hole 201 is recessed inward along the circumference of the second protrusion 1013 to form an annular groove 2015; the inner wall of the annular groove 2015 is covered with a fourth magnetic body 2014.

[0063] The second protrusion 1013 can extend into the annular slot 2015 and form a sliding engagement, and the polarity of the contact surfaces of the third magnetic body 1014 and the fourth magnetic body 2014 are opposite.

[0064] It should be noted that the annular slot 2015 is a continuous closed annular structure, and the annular slot 2015 is set horizontally.

[0065] In this way, when the second protrusion 1013 extends into the first slot 2013 and forms a sliding engagement, the second protrusion 1013 can rotate and slide arbitrarily along the annular slot 2015. That is, when the clip 20 rotates relative to the wireless guide 10, the annular slot 2015 will also rotate relative to the second protrusion 1013 until the clip 20 rotates to the ideal angle relative to the wireless guide 10. At this time, the third magnetic body 1014 on the outer side wall of the second protrusion 1013 will attract each other with the fourth magnetic body 2014 on the inner side wall of the first slot 2013, thereby forming a magnetic fixation, further improving the stability between the connector 101 and the first through hole 201, thereby reducing the situation where the clip 20 rotates to the ideal angle relative to the wireless guide 10 and then rotates again due to external vibration.

[0066] Of course, when the outer wall of the second protrusion 1013 is covered with the third magnetic body 1014, the inner wall of the annular slot 2015 is covered with a magnetic material that can be attracted by a magnet (such as iron, aluminum nickel cobalt, nickel, etc.); or the inner wall of the annular slot 2015 is covered with the fourth magnetic body 2014, then the outer wall of the second protrusion 1013 is covered with a magnetic material that can be attracted by a magnet, which is not limited here.

[0067] In other embodiments, to further improve the smoothness of rotation between the connector 101 and the first through hole 201, such as... Figure 7 As shown, the outer side wall of the connector 101 is provided with a matching receiving groove 1015 corresponding to each of the second protrusions 1013, and at least one elastic body 1016 is provided between the bottom wall of the receiving groove 1015 and the corresponding second protrusion 1013.

[0068] It should be noted that the second protrusion 1013 in this embodiment can undergo elastic deformation.

[0069] Thus, when the clip 20 rotates relative to the wireless guide 10, the second protrusion 1013 will be subjected to a radial pulling force, causing the second protrusion 1013 to undergo radial compression deformation. At the same time, the second protrusion 1013 will move into the receiving groove 1015, thereby squeezing the elastic body 1016 and causing it to undergo elastic deformation, thereby disengaging from the mechanical lock of the current first slot 2013. Then, when the clip 20 rotates relative to the wireless guide 10 to the ideal angle, the guide releases the clip and removes the external force. At this time, the elastic body 1016 will push the second protrusion 1013 to rebound radially due to its own elastic deformation, embedding into the corresponding first slot 2013 and completing self-locking.

[0070] In some embodiments, to further ensure that the clip 20 does not detach from the wireless guide 10, such as Figure 2 As shown, the top end of the connector 101 is recessed inward to form a threaded hole 1017, and the threaded hole 1017 is fitted with a fastener 102.

[0071] The fastener 102 can pass through the first through hole 201 and be threaded to the threaded hole 1017, and the outer diameter of the head of the fastener 102 is larger than the inner diameter of the annular block 2011.

[0072] It should be noted that the fastener 102 proposed in this embodiment is preferably a screw, which can be threaded to the threaded hole 1017 by passing a screwdriver through the second through hole 206. The head of the fastener 102 clamps the annular block 2011 in conjunction with the threaded hole 1017.

[0073] It is understood that the wireless lavalier guide proposed in this utility model includes the WiFi unit, Bluetooth unit, battery management unit, etc. that should be present in existing guides.

[0074] In some embodiments, such as Figure 1 and Figure 8 As shown, a first protective sleeve 103 containing a microphone assembly 104 is provided on one side of the top of the wireless tour guide 10, and a plurality of sound pickup holes 1031 are provided on the outer side wall of the first protective sleeve 103; a second protective sleeve 105 containing an antenna assembly 106 is provided on the other side of the top of the wireless tour guide 10.

[0075] The wireless guide device 10 is equipped with a main control unit 107 and a translation component 108. The main control unit 107 is electrically connected to the microphone component 104, the antenna component 106 and the translation component 108 respectively.

[0076] It is understood that the main control unit 107 proposed in this embodiment includes, but is not limited to, a main control chip, an analog-to-digital conversion circuit, a modulation chip, and an RF amplifier chip. The first protective cover 103 is used to protect the microphone assembly 104 from damage, and the pickup hole 1031 facilitates the microphone assembly 104 to collect the speaker's voice signal; the second protective cover 105 is used to protect the antenna assembly 106 from damage.

[0077] In this embodiment, the microphone component 104 is used to collect the speaker's voice signal and outputs an analog audio signal to the translation component 108 through a built-in pre-amplification circuit. The translation component 108 then receives the analog audio signal and preprocesses it using a noise reduction algorithm. It then calls a pre-trained speech recognition model (supporting multiple languages ​​such as Chinese, English, Japanese, French, and Korean) within the translation component 108 to convert the speech into text. The translation component 108 then generates target language text based on neural machine translation (NMT) and synthesizes target language speech. Finally, the analog speech signal containing the synthesized target language speech is processed... The analog-to-digital converter circuit in the main control unit 107 converts the signal into a digital signal and outputs it to the modulation chip (QPSK / 16-QAM programmable digital modulator) in the main control unit 107. The modulation chip then maps the digital signal into a radio frequency carrier (2.405-2.480GHz) and outputs the modulated signal. The radio frequency amplifier chip in the main control unit 107 amplifies the modulated signal to a set power and then outputs the radio frequency signal to the antenna assembly 106. The antenna assembly 106 converts the radio frequency signal into electromagnetic wave radiation and outputs it to the receiver (preferably a Bluetooth device worn on the listener's ear).

[0078] In some embodiments, such as Figure 1 As shown, the top of the wireless explanation device 10 is provided with a microphone interface 109, which is electrically connected to the main control unit 107. The microphone interface 109 is used to connect an external microphone device.

[0079] In noisy environments (such as exhibitions and construction sites), external microphone devices can capture the speaker's voice in a specific direction, suppress environmental noise interference, and significantly improve the quality of voice acquisition and environmental adaptability.

[0080] Among them, such as Figure 10 As shown, the outer wall of the wireless tour guide 10 is also provided with a charging port 110, which is electrically connected to the rechargeable battery 111 inside the wireless tour guide 10, and the rechargeable battery 111 is electrically connected to the main control unit 107.

[0081] Among them, such as Figure 9As shown, the wireless guide device 10 has an operation panel 112 on its outer side wall facing away from the clip 20. The operation panel 112 has a display screen 113 and a button assembly 114. The display screen 113 and the button assembly 114 are electrically connected to the main control unit 107.

[0082] The presenter can start and stop the wireless tour guide 10 via the button component 114, and can also select the target language for translation via the button component 114 and display the target language on the display screen 113.

[0083] In other embodiments, such as Figure 1 As shown, the wireless tour guide 10 includes a first housing 115 and a second housing 116 that fit together; wherein, the outer side wall of the first housing 115 facing away from the second housing 116 is provided with an operation panel 112, and the outer side wall of the second housing 116 facing away from the first housing 115 is provided with a connector 101 protruding outward.
