[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0062] like Figures 1 to 7 As shown, an easy-to-assemble speaker box includes a housing and a speaker assembly 20, a main control circuit board 30, and a microphone 42 assembly 40 installed in the housing;

[0063] The housing includes an upper shell 101 and a lower shell 102 , which are assembled to form a receiving cavity. The speaker assembly 20 , the main control circuit board 30 and the microphone 42 assembly 40 are all installed in the receiving cavity.

[0064] In this embodiment, the upper housing 101 includes an insulating housing 11, a touch key panel 12, an annular light guide plate 13 and a sound-transmitting cover plate 14;

[0065] The insulating shell 11 is connected to the lower shell 102. The insulating shell 11 has an inner cavity 111 with an opening at the lower end. A plurality of semi-transparent touch button silk-screen areas 112 are provided on the insulating shell 11. In this embodiment, there are five semi-transparent touch button silk-screen areas 112 and they are evenly arranged along the circumference.

[0066] The upper end surface of the insulating housing 11 is recessed downwardly to form a first groove 113 for mounting the annular light guide plate 13. The inner bottom wall of the first groove 113 is downwardly formed with a through hole 114 and a plurality of backlight holes 115 surrounding the first groove 113 along its circumference. The backlight holes 115 extend from the inner bottom wall of the first groove 113 to the inner cavity 111.

[0067] The annular light guide plate 13 includes an annular base portion 131 and an annular side plate portion 132 integrally extending upward from the outer periphery of the annular base portion 131. The annular light guide plate 13 is installed in the first groove 113. The annular base portion 131 is connected to the inner bottom wall of the first groove 113 and covers all the backlight holes 115. The annular side plate portion 132 is connected to the inner side wall of the first groove 113.

[0068] A second groove for accommodating the sound-transmitting cover plate 14 is formed between the upper end surface of the annular base plate portion 131 and the inner side surface of the annular side plate portion 132. The sound-transmitting cover plate 14 is installed in the second groove, and the outer periphery of the sound-transmitting cover plate 14 is connected to the annular side plate portion 132. The annular side plate portion 132 is sandwiched between the sound-transmitting cover plate 14 and the insulating housing 11.

[0069] The touch key panel 12 is provided with a touch chip 121, a plurality of touch sensing electrodes 122, a plurality of first indicator lights 123 and a plurality of second indicator lights 124;

[0070] All touch sensing electrodes 122 are respectively connected to the touch chip 121. The touch chip 121, the first indicator light 123, and the second indicator light 124 are all electrically connected to the main control circuit board 30. The touch sensing electrodes 122 are configured with a first indicator light 123. The number of the touch sensing electrodes 122 is the same as the number of the semi-transparent touch key silk-screen areas 112. The touch sensing electrodes 122 are laminated to the inner top wall of the inner cavity 111 corresponding to the semi-transparent touch key silk-screen area 112 via an annular conductive foam 125. The light emitted by the first indicator light 123 passes through the inner cavity of the annular conductive foam 125 toward the corresponding semi-transparent touch key silk-screen area 112 to illuminate the semi-transparent touch key silk-screen area 112.

[0071] The number of the second indicator lights 124 is consistent with the number of the backlight holes 115. Each second indicator light 124 extends into the corresponding backlight hole 115 and the touch key panel 12 covers the lower end opening of the backlight hole 115. The light emitted by each second indicator light 124 passes through the backlight hole 115 into the annular light guide plate 13 and is output from the top of the annular side plate 132.

[0072] Through the setting of the annular light guide plate 13, the light of the second indicator light 124 is transmitted only through the upper end surface of the annular side plate 132 of the annular light guide plate 13 in the backlight hole 115, which plays the role of an aperture prompt and at the same time reduces the brightness of the transmitted light source, making the light softer and more evenly distributed, avoiding the light being too glare and affecting the user.

[0073] A positioning block 116 is formed on the inner bottom wall of the lower housing 102 , and a positioning protrusion 117 is protruded from the upper end surface of the positioning block 116 .

[0074] The main control circuit board 30 is installed below the speaker assembly 20 , and the main control circuit board 30 is electrically connected to the speaker assembly 20 and the microphone 42 assembly 40 .

[0075] The microphone 42 assembly 40 includes an FPC board 41 and a plurality of microphones 42 spaced apart on the FPC board 41 and electrically connected to the FPC board 41. A plurality of embedding slots 118 for embedding corresponding microphones 42 are formed on the inner sidewall of the lower housing 102, with each microphone 42 embedded in a corresponding embedding slot 118. In this embodiment, two FPC boards 41 are provided. Preferably, the two FPC boards 41 are rotationally symmetrical. Four microphones 42 are spaced apart on the FPC board 41, each microphone 42 being electrically connected to the FPC board 41. Preferably, the microphones 42 are digital microphones. A total of eight microphones 42 are arranged on the two FPC boards 41 at evenly spaced intervals. This allows for more accurate and more efficient determination of the sound source and reduces distortion in voice localization.

[0076] The main control circuit board 30 has a first conductive portion for electrical connection thereto. In this embodiment, the first conductive portion includes an insulating seat 31 disposed on the lower end surface of the main control circuit board 30 and six conductive pins 32 disposed on the insulating seat 31. The six conductive pins 32 are electrically connected to the main control circuit board 30.

[0077] The FPC board 41 includes a circular side panel 411 and an extension 412 that extends horizontally and is bent inward from the lower end of one end of the circular side panel 411. The extension 412 is provided with a positioning hole 413. The extension 412 is connected to the positioning block 116, and the positioning protrusion 117 is installed in the positioning hole 413 and extends out of the extension 412.

[0078] The FPC board 41 has a second conductive portion for electrical connection thereto, the second conductive portion being disposed on the extension portion 412. When the first conductive portion and the second conductive portion are electrically connected, the main control circuit board 30 is electrically connected to the FPC board 41 so that the main control circuit board 30 is electrically connected to the microphones 42.

[0079] The second conductive portion includes six conductive contacts 414, preferably circular contacts 414. The six conductive contacts 414 are electrically connected to the FPC board 41 so that the six conductive contacts 414 are electrically connected to corresponding microphones 42. Each conductive pin 32 is electrically connected to a corresponding conductive contact 414 after abutting against it.

[0080] The key points of the design of this utility model are: it mainly installs the main control circuit board below the speaker assembly, and embeds the microphone assembly in the lower shell to make it modular with the lower shell, which is convenient to assemble and greatly improves the assembly efficiency of the speaker;

[0081] Secondly, by separating the light of the first indicator light and the second indicator light, the light of the first indicator light can only be guided out through the light guide plate, making the light soft and uniform, thereby improving the comfort of use.

[0082] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
