Description

Technical Field

[0001] The present invention belongs to the technical field of sound pickup buttons, and particularly relates to a sound pickup button structure and an electronic product. Background Art

[0002] The sound pickup is widely used in various intercom products and voice control products. The microphone is an important part of the sound pickup. After the microphone collects the sound signal, it is filtered and amplified through the circuit board on the sound pickup, and the sound pickup transmits the processed sound signal to the main circuit board of the product.

[0003] In the prior art, products with buttons and voice control functions integrate the sound pickup on the function buttons. For example, intelligent switches, voice control keyboards, voice control remote controls, intelligent home panels, etc. When designing the sound pickup for these products, the microphone or the microphone circuit board is generally connected to the main circuit board through a group of relatively long wires or flexible cables. In this way, when producing and assembling the product, a relatively long length of wire needs to be reserved to facilitate the operation and assembly. However, since the wire material is usually a soft material and is not controllable, it is very difficult to install the wire to the designed predetermined position, and problems such as wire pressing and shell separation often occur, resulting in reinstallation and low production efficiency; moreover, if the wire is located at the screw hole position, the wire will be broken by the screw, resulting in the failure of the sound pickup and an increase in the defective rate of the product.

[0004] Therefore, in view of the above technical problems, the present invention provides a sound pickup button structure in which the microphone circuit board is connected to the main circuit board through spring pins, canceling the wire connection, so as to solve one or more of the above problems. Summary of the Invention

[0005] In view of the above problems existing in the prior art, the present invention provides a sound pickup button structure, including:

[0006] A top cover member, on which a button body and a support body are installed. Inside the top cover member, a microphone slot is provided, outside the microphone slot, a mounting seat is provided, and the top cover member is provided with a microphone hole communicating with the microphone slot;

The front side of the microphone board integrates the microphone device, the microphone device is received in the microphone slot, and conductive contacts are provided on the back side of the microphone board. The key board integrates a switch button and spring pins, and the key board is fixedly installed on the bracket body. The bracket body is fixedly connected to the top cover member, and the spring pins abut against the conductive contacts on the microphone board and press the microphone board, thereby realizing the conduction between the microphone board and the key board. The two circuit boards of the sound pickup key structure are directly connected through the spring pins and the conductive contacts, canceling the conventional structure of wire connection, and there are no problems of wire pressing and shell separation, nor the problem of the wire being broken by a screw, solving the problems of wire pressing or wire breakage in the conventional technology, and improving the production efficiency and product yield of the product.

[0011] Optionally, the mounting seat is provided with a first positioning post, and the microphone board is provided with a first positioning hole. The microphone board is inserted into the first positioning post through the first positioning hole for positioning and installation.

The button board 3 is fixedly installed on the bracket body 4 by screws, and the bracket body 4 is fixedly connected to the top cover member 1 by screws. The spring pins 12 abut against the conductive contacts 10 on the microphone board 2 and press the microphone board 2 tightly, so as to realize the conduction between the microphone board 2 and the button board 3. The two circuit boards of the sound pickup button structure in this embodiment are directly connected through the spring pins 12 and the conductive contacts 10, canceling the conventional structure of wire connection, and there are no problems of wire pressing and shell separation, nor the problem of the wire being broken by a screw, solving the problems of wire pressing or wire breakage in the conventional technology, and improving the production efficiency and product yield of the product.

[0052] Further, in some embodiments, the spring pins 12 can also be provided on the microphone board 2, and the conductive contacts 10 are provided on the button board 3. In some embodiments, the spring pins 12 can be replaced by conventional pins, and the conventional pins are equivalent to conductive plugs, and the corresponding conductive contacts 10 are replaced by conductive sockets or conductive receptacles.

[0053] Further, a first positioning post 13 is provided on the mounting base 7, and a first positioning hole 14 is provided on the microphone head board 2. The microphone head board 2 is positioned and installed by inserting the first positioning hole 14 into the first positioning post 13. Specifically, in this embodiment, in order to facilitate the positioning and installation of the microphone head board 2, two first positioning posts 13 symmetrical to the microphone head slot 6 are provided on the mounting base 7. The first positioning posts 13 are integrally formed with the top cover member 1. Two first positioning holes 14 symmetrical to the microphone head 9 are provided on the microphone head board 2. When installing the microphone head board 2, the microphone head 9 is placed into the microphone head slot 6, and the first positioning posts 13 are inserted into the first positioning holes 14 for positioning and installation, so that the spring pins 12 can accurately contact the conductive contacts 10. It should be noted that in some embodiments, in order to facilitate the positioning and installation of the microphone head board 2, an installation slot (not shown) having the same shape as the microphone head board 2 may also be provided at the upper part of the microphone head slot 6. The installation slot and the microphone head slot 6 form a stepped slot, and the microphone head board 2 is directly installed into the installation slot for positioning and installation. Particularly, when installing the microphone head board 2, if necessary, the microphone head board 2 may be first fixed to the mounting base 7 by sol bonding.

[0054] Further, a foolproof post 15 is provided on one side of the mounting base 7. The positioning end of the microphone head board 2 abuts against the foolproof post 15, and the foolproof post 15 determines the assembly direction of the microphone head board 2. Herein, the end of the microphone head board 2 abutting against the foolproof post 15 is the positioning end, and the other end is the free end. Specifically, in this embodiment, a foolproof post 15 is provided on one side of the mounting base 7. The foolproof post 15 protrudes in the shape of a rectangular column, and the foolproof post 15 is also integrally formed with the top cover member 1. The distance between the abutting surface of the foolproof post 15 and the first positioning post 13 on the same side thereof is equal to the distance between the end face of the positioning end of the microphone head board 2 and the first positioning hole 14 on the same side thereof, and is less than the distance between the end face of the free end of the microphone head board 2 and the first positioning hole 14 on the same side thereof. With such a design, the microphone head board 2 can be installed only when the positioning end side is installed on the side of the foolproof post 15, achieving the function of foolproof installation by determining the direction of the microphone head board 2. The directionally installed microphone head board 2 is particularly important when there are polarity requirements, avoiding the situation of reverse connection of positive and negative poles and damaging the circuit of the entire product. In some embodiments, the microphone head board 2 may also be provided with an indicating portion 16, such as a forward arrow. When installing the microphone head board 2, it is required that the arrow direction must be forward or backward with respect to the foolproof post 15 to avoid reverse polarity connection of the microphone head board 2.

The expansion slots 17 communicate with the microphone slot 6 and are used to accommodate and glue the microphone board 2. The microphone device 9 is also equipped with a silica gel sleeve 18. The silica gel sleeve 18 is sleeved on the microphone device 9, and the glue is used to bond the silica gel sleeve 18. Specifically, in this embodiment, since the microphone board 2 is not fixed when installed on the mounting seat 7, two expansion slots 17 are symmetrically arranged on both sides of the microphone slot 6 to glue and bond the microphone board 2. The microphone slot 6 is a rectangular open slot, which is also integrally formed with the top cover part 1. The microphone slot 6 can be symmetrically arranged or circumferentially arranged. After the microphone board 2 is installed on the mounting seat 7, glue is poured into the expansion slots 17. After the glue solidifies, the microphone board 2 can be firmly bonded to the top cover part 1, achieving the purpose of firmly installing the microphone board 2 on the mounting seat 7. During actual glue filling, the glue is poured from one side of the expansion slot 17, extends through the back of the microphone board 2, and reaches the other side of the expansion slot 17, so that the microphone board 2 is bonded more firmly and reliably. In order to prevent the microphone device 9 from being overly covered by glue or even having the microphone hole 8 blocked, affecting the sound pickup effect, before the glue bonding of the microphone board 2, a silica gel sleeve 18 is configured to be sleeved on the microphone device 9, so that the glue only bonds the silica gel sleeve 18. The silica gel sleeve 18 isolates the glue and keeps the microphone hole 8 unobstructed. The silica gel sleeve 18 acts as a protective cover. The silica gel sleeve 18 is formed with an opening corresponding to the front of the microphone device 9, and the opening is directly opposite to the microphone hole 8, so that the sound signal can be transmitted from the microphone hole 8 to the microphone device 9, ensuring the normal operation of the microphone device 9.
