[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0027] Referring to Figure 1 and Figure 2 The utility model discloses a loudspeaker equipment convenient for wiring, which comprises a shell 10, the shell 10 is equipped with mounting cavity and connecting surface 11, specifically, the mounting cavity is equipped with control board 20 and sound assembly, and the sound assembly is electrically connected with control board 20. In which, connecting surface 11 is equipped with a plurality of interfaces 22, and a plurality of interfaces 22 are electrically connected with control board 20.

[0028] On the basis of the structure, when the sound amplification device is used, the plug corresponding to the external device can be inserted into the corresponding interface 22 on the connecting surface 11, for example, the plug of the charging wire is inserted into the charging interface 114 to charge the device, the U disk storing the audio file is inserted into the USB interface 112, and the wired earphone plug is inserted into the earphone interface 113 to realize the audio output and input functions.

[0029] Then the audio content can be played through the sound assembly. Specifically, the audio signal is captured by the microphone 40 of the sound assembly, transmitted to the control panel 20 of the sound amplification device through the connected audio line, processed and amplified by the control panel 20, and then transmitted to the sound assembly. The loudspeaker of the sound assembly converts the electrical signal into a sound signal and propagates the amplified sound, thereby realizing the sound amplification effect of the audio and meeting the user's demand for sound amplification in different occasions.

[0030] Therefore, the input audio signal is amplified and processed by the control panel 20, and the amplified signal is converted into a larger volume of sound output by the sound assembly, so that the originally smaller sound can be clearly heard in a larger space range, realizing the sound amplification effect.

[0031] In addition, the utility model discloses a plurality of interfaces 22 are arranged on the connecting surface 11, and the user does not need complicated wiring or professional wiring knowledge, and only needs to select the corresponding interface 22 for connection according to the plug type. At the same time, the user can only carry out all wiring operations on the connecting surface 11, without frequently adjusting the position or angle of the sound amplifier, simplifying the wiring process. Especially when used in outdoor environment, it can improve the operation efficiency, help to quickly put into use in emergency situation, and reduce the occurrence of wrong port insertion.

[0032] It should be noted that the circuit board is provided with a plurality of function modules 21, which specifically include a charging management module in the prior art, an audio processing module for earphone access and a USB storage device processing module, etc. These function modules 21 communicate with external devices through the interface 22 to realize various function extensions and charging operations.

[0033] Further, referring to Figure 2 The shell 10 includes a face cover 13, a front shell 14 and a rear shell 15, wherein the two sides of the front shell 14 are respectively detachably connected with the face cover 13 and the rear shell 15. In addition, the mounting cavity includes a first mounting cavity and a second mounting cavity, specifically, the first mounting cavity is formed between the face cover 13 and the front shell 14, and the second mounting cavity is formed between the front shell 14 and the rear shell 15.

[0034] On the basis of the structure, when assembling the shell 10, the sound assembly, the control panel 20 and related lines and other components can be installed in the corresponding installation cavities first to ensure that the components are installed firmly and the lines are connected correctly. Then, the two sides of the front shell 14 are connected with the face cover 13 and the rear shell 15 respectively.

[0035] The connection mode of the front shell 14 with the face cover 13 and the rear shell 15 can be snap connection, that is, the two sides of the front shell 14 are pressed slightly to make the snap buckle correspond to the snap groove of the face cover 13 and the rear shell 15. Alternatively, the front shell 14 can be fixed by screws, that is, the screwdriver is used to tighten the screws to ensure that the connection is tight, so that the entire shell 10 forms a complete closed structure, protecting the internal electronic components and assemblies from physical damage from the outside, and also providing a stable environment for the internal circuit and sound propagation.

[0036] Further, the sound assembly includes a loudspeaker 30, and the loudspeaker 30 is arranged in the first installation cavity. In addition, the face cover 13 is provided with a sound guide surface 12, and a plurality of sound guide holes 121 are arranged on the sound guide surface 12 and extend through the first installation cavity. The loudspeaker 30 is arranged opposite to the sound guide surface 12, and the sound guide surface 12 is used to guide the sound waves of the loudspeaker 30 to be guided out.

[0037] On the basis of the structure, when assembling, the loudspeaker 30 is first stably installed in the first installation cavity, and it is ensured that the side of the loudspeaker 30 with the diaphragm faces the face cover 13. Then, the two sides of the front shell 14 are connected with the face cover 13 and the rear shell 15 respectively.

[0038] When the control panel 20 receives the audio signal, the control panel 20 processes the audio signal, and then transmits the processed audio signal to the loudspeaker 30 located in the first installation cavity. After the loudspeaker 30 receives the electrical signal, the diaphragm starts to vibrate to generate sound waves. Since the loudspeaker 30 is arranged opposite to the sound guide surface 12 on the face cover 13, the sound waves will propagate towards the sound guide surface 12, and then be guided out through the plurality of sound guide holes 121 on the sound guide surface 12.

[0039] The sound guide holes 121 play a role in guiding sound waves, so that the sound waves can be more concentrated and orderly propagated outward. In addition, the sound guide holes 121 can prevent foreign matters in the outside from directly contacting the internal sound assembly such as the loudspeaker 30 to a certain extent. Dust, small particles and other impurities are difficult to enter the inside of the device through the sound guide holes 121, because the sound guide holes 121 are relatively small and have a certain depth, which plays a barrier role.

[0040] In addition, the connecting surface 11 is also provided with adjustment buttons, which are in contact with corresponding contacts on the circuit board through conductive rubber or metal springs, so as to realize the conduction of the circuit. The user can adjust the volume and tone through the adjustment buttons. The adjustment of the volume directly affects the vibration amplitude of the diaphragm of the loudspeaker 30, thereby changing the loudness of the sound emitted from the sound guide hole 121. The buttons are provided with indicator lights to indicate the on-off state of the button function.

[0041] Further, the sound assembly includes a microphone 40, and the microphone 40 is arranged in the second mounting cavity. The top wall and the side wall of the rear shell 15 are connected by an inclined surface, and the sound guide hole 115 is arranged on the inclined surface, and the microphone 40 is arranged opposite to the sound guide hole 115.

[0042] On the basis of the structure, during assembly, the microphone 40 can be fixedly installed in the second mounting cavity and arranged opposite to the sound guide hole 115 on the rear shell 15. When shouting, the user can speak towards the sound guide hole 115, and since the microphone 40 is arranged opposite to the sound guide hole 115, the incoming sound can be directly captured by the microphone 40.

[0043] It should be noted that the top wall and the side wall of the rear shell 15 are connected by an inclined surface, and the sound guide hole 115 is arranged on the inclined surface, which makes it easier and more direct for the user to shout into the sound guide hole 115 without having to deliberately adjust the position of the head or the mouth.

[0044] The sound collecting part (such as a microphone diaphragm) of the microphone 40 generates a corresponding electrical signal according to the vibration of the sound, thereby realizing the conversion of sound to electrical signal. The electrical signal collected by the microphone 40 is transmitted to the control board 20, and the control board 20 processes the electrical signal. The processed electrical signal is transmitted to the sound output assembly such as the loudspeaker 30, and the loudspeaker 30 converts the electrical signal into a sound signal for playing, thereby realizing the effect of amplifying the sound collected by the microphone 40 and allowing the surrounding listeners to clearly hear the content of the speech.

[0045] Therefore, the microphone 40 is arranged in the second mounting cavity and opposite to the sound guide hole 115, which can accurately collect the sound transmitted through the sound guide hole 115, ensuring the accuracy and effectiveness of sound collection. It should be noted that when the user speaks towards the sound guide hole 115 on the rear shell 15, the amplified sound is guided out by the face cover 13. That is, when the user shouts, the sound amplification device is directed forward, which can make the sound more concentratedly propagate forward, effectively expand the propagation range and coverage area of the sound, and keep the sound clear at a long distance, ensuring that the shouting information can be clearly received in a large space or noisy environment.

[0046] In addition, the connector of the wired microphone 40 can be inserted into the corresponding interface 22, and the sound signal collected by the wired microphone 40 can be transmitted to the control panel 20 through the line.

[0047] Further, the control panel 20 is arranged in the second installation cavity, and the connecting surface 11 is formed on one side of the rear shell 15. The control panel 20 is connected with the loudspeaker 30 and / or the microphone 40 through the wire.

[0048] The relative position between the connecting surface 11 and the control panel 20 is compact, and the control panel 20 and the interface 22 on the connecting surface 11 can be connected with each other conveniently. It should be noted that the connecting surface 11 can also be arranged on the bottom or the top of the shell 10.

[0049] Therefore, the loudspeaker 30 is arranged in the first installation cavity, and the control panel 20 is arranged in the second installation cavity, so that the loudspeaker 30 and the control panel 20 and other components are isolated, the influence of the electromagnetic interference generated by the electronic components during the operation on the sound signal can be reduced, and the noise and the noise in the audio output are reduced.

[0052] On the basis of the structure, the shell 10 is further provided with the power indication device, which can be an indicator light or a digital display. When the sound amplification equipment is turned on, the control panel 20 will first detect the power state of the battery 50. The battery 50 is connected with the control panel 20 through the internal circuit, and the power management module on the control panel 20 can obtain the voltage and other information of the battery 50, so as to determine whether the power of the battery 50 is sufficient, and the residual power state can be displayed in real time through the power indication device.

[0053] It should be noted that the battery 50 is a lithium battery 50 in the prior art, and the scale is that the rated voltage is 7.4V, the rated capacity is greater than or equal to 2000mAh, the rated energy is greater than or equal to 14Wh, and the charging time is less than or equal to 3 hours, so that the long-time continuous use is ensured.

[0054] In addition, the warning light 60 can effectively remind the surrounding personnel through the flashing visual signal of the high-brightness red and blue LED light, and the flashing mode can be adjusted cyclically.

[0055] Further, the shell 10 is provided with a holding portion 16. Specifically, the holding portion 16 includes recessed areas 161 provided on both sides of the shell 10 and a protruding area 162 provided at the front end of the shell 10.
