Embodiment 1
[0047] like figure 1 and Figure 4 As shown, this voice announcement box control key A is installed on the rear cover 1, the rear cover 1 is a housing structure with an accommodating chamber, and there are several avoidance holes 13 on the rear cover 1 for the control of the voice announcement box control key A. The button 3 is installed to avoid, that is, the control button 3 will pass through the avoidance hole 13 to form a state of being exposed on the rear surface of the back cover 1 to facilitate the user's manipulation and pressing.
[0048] Specifically, as Figure 5-Figure 6 As shown, the control key base 2 in this embodiment includes a central control key installation cylinder 20, a side control key installation cylinder 21, a connecting elastic arm 22 and a limiting protrusion 23, which are made of elastic plastic material or silica gel and are integrally formed by injection molding.
[0049] The connecting elastic arm 22 has a certain elastic force, so as to play ...
Embodiment 2
[0065] like Figure 1-Figure 6 As shown, the present embodiment provides a voice announcement box including a rear cover 1 and a front cover 5 that opens and closes the rear cover 1, a panel 8 is installed on the front cover 5, and the voice announcement box also includes a built-in rear cover 1 and a front cover 5. The cover 5 forms the control circuit 4 in the inner chamber, and the control circuit 4 is connected with a speaker.
[0066] The rear cover 1 is provided with grid holes 14 corresponding to the speakers, so as to facilitate the external transmission of sound.
[0067] The control circuit 4 is connected to the battery 7 in the inner chamber, and the battery 7 is a rechargeable battery or dry battery. Of course, the control circuit 4 can also be connected to a power cord with a plug, and the plug is electrically connected to the external mains.
[0068] Specifically, as Figure 7 As shown, the control circuit 4 of this embodiment includes a main control unit circu...

Abstract
The invention relates to a voice broadcast box, a control key and an assembling method. The defects of unreasonable design and the like in the prior art are overcome. The voice broadcast box control key comprises a control key seat, a plurality of control keys are mounted on the control key seat, and the control key seat comprises a central control key mounting cylinder; at least one side control key mounting cylinder is arranged; each side control key mounting cylinder is connected with the central control key mounting cylinder through two symmetrically distributed connecting elastic arms; the limiting protruding part is arranged on the side face, close to the center control key installation cylinder, of the connecting elastic arm, and a gap is reserved between the limiting protruding part and the outer wall of the center control key installation cylinder. The central control key mounting cylinder, the connecting elastic arm and the side control key mounting cylinder are arranged in the positioning cylinder of the rear cover, and the connecting elastic arm is propped against the inner wall of the positioning cylinder. The control key seat has the advantages that the mode that the corresponding connecting elastic arms abut against the inner wall of the positioning cylinder is utilized, rapid installation of the control key seat can be achieved, and the installation stability is ensured.
Description
technical field [0001] The invention belongs to the technical field of voice reminders, and in particular relates to a voice broadcast box, a control key and an assembly method. Background technique [0002] During mobile payment, the payment information can be prompted by voice by designing a voice broadcast box. [0003] Existing voice broadcast boxes are generally provided with control buttons, and the purpose of the buttons is mainly to control the volume, switch the machine on and off, and replay the last transaction information. [0004] The existing key base opposite to the key is a single independent structure, and each key base needs to be installed separately during installation, which is inefficient. SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to address the above problems, and to provide a voice broadcast box, a control key and an assembling method that can solve the above technical problems. [0006] To achieve the above object,...
