Description

Speaker equipment and its electronic device

The present invention relates to a speaker device and an electronic device, and more particularly to a speaker device having an encoding function and an electronic device.

In general, many electronic components are mounted inside an electronic device, and some of the more sophisticated electronic components are secured in the electronic device, which is important to those skilled in the relevant art. More sophisticated electronic components, such as encoders, are sensors, software, or algorithms that convert information from a specific or encoded code to other specific codes. The purpose of the conversion may be due to standardization, speed, confidentiality, security. Or to compress the data. According to its scale method and signal output form, the encoder can be divided into incremental encoder and absolute encoder, and the incremental encoder can be used for volume control and function table selection.

For an encoder for volume control, the encoder is fixed to the circuit board of the electronic device, and the rotary volume knob is set to the encoder. However, since both the encoder and the board are manufactured with a certain tolerance range, this tolerance range easily causes an assembly problem between the rotary volume knob and the encoder, so that the rotary volume knob cannot be rotated relative to the encoder and loses its function. For example, encoders are usually soldered to a circuit board using Surface-mount technology (SMT). However, manufacturing tolerances may occur due to factors such as uneven thickness of the conductive paste or poor flatness of the surface of the board.

In view of the above problems, the present invention discloses a speaker device and an electronic device, which contribute to solving the assembly problem between the rotary volume knob and the encoder due to manufacturing tolerances.

The electronic device disclosed in the present invention comprises a casing, an electronic component, a rotating component and a positioning module. The casing includes a connected bottom plate and a side plate. The electronic component includes a fixed circuit board and an electronic component, and the circuit board is located in the casing and disposed on the bottom plate. The rotating member sequentially passes through the side plate and a positioning hole of the electronic component. The positioning module is disposed in the casing and fixed to the bottom plate, and the positioning module passes through the circuit board of the electronic component. The positioning module has a stop surface facing the bottom plate, and a part of the circuit board is between the stop surface and the bottom plate. The spacing between the stop surface and the bottom plate is greater than the thickness of the circuit board.

The electronic device further disclosed in the present invention comprises a casing, a circuit board and a positioning module. The circuit board is disposed in the casing. The positioning module is disposed in the casing and fixed to the casing, and the positioning module passes through the circuit board of the electronic component. The positioning module has a stop surface facing the casing, and a part of the circuit board is between the stop surface and the casing. The distance between the stop surface and the casing is greater than the thickness of the circuit board.

The speaker device disclosed in the present invention comprises the aforementioned electronic device.

Thereby, the circuit board is floatingly disposed in the casing. Before the rotating component and the electronic component are assembled, the circuit board can move relative to the positioning module and the casing between the stopping surface and the bottom plate of the casing. When the rotating member penetrates the positioning hole of the electronic component, the rotating member gives a force to the electronic component, and drives the circuit board to move up and down to align the axis of the rotating member with the center of the positioning hole. Thereby, when the circuit board or the electronic component has manufacturing tolerances, the position of the circuit board can be adjusted to maintain a good assembly between the rotating member and the electronic component.

The following examples are intended to describe the present invention in further detail, but are not intended to limit the scope of the invention.

Please refer to FIG. 1A to FIG. 1B at the same time. 1A is a perspective view of an electronic device according to a first embodiment of the present invention. FIG. 1B is a schematic cross-sectional view of the electronic device of FIG. 1A. In this embodiment, the electronic device 1 includes a casing 10, an electronic component 20, a positioning module 30, and a rotating member 40.

The casing 10 includes a bottom plate 110 and a side plate 120 connected thereto. The side plate 120 is located at one side of the bottom plate 110, and the side plate 120 has an opening 121. In the present embodiment, the normal direction N1 of the bottom plate 110 is substantially orthogonal to the normal direction N2 of the side plate 120.

The electronic component 20 is disposed in the casing 10 and includes a circuit board 210 and an electronic component 220. The electronic component 220 is fixed to the circuit board 210. For example, the electronic component 220 can have a plurality of pins that are inserted or soldered to the metal pads of the circuit board 210. Electronic component 220 is, for example but not limited to, an encoder. The circuit board 210 has a top surface 211 and a bottom surface 212 opposite to each other, and the bottom surface 212 faces the bottom plate 110 of the casing 10. Further, the electronic component 220 has a positioning hole 221.

The positioning module 30 is disposed in the casing 10 and fixed to the bottom plate 110 , and the positioning module 10 is disposed through the circuit board 210 . In detail, the positioning module 30 can include a positioning post 310 , a stop 320 , and a fastener 330 .

The positioning post 310 is fixed to the bottom plate 110, and the positioning post 310 has an upper surface 311 and a fastening hole 312 located on the upper surface 311. The positioning post 310 protrudes from the bottom plate 110 to have a height H. The circuit board 210 is disposed on the bottom plate 110 of the casing 10, and the positioning post 310 is disposed through the circuit board 210. The height H of the positioning post 310 protruding from the bottom plate 110 is greater than the thickness T of the circuit board 210. In this embodiment, the positioning post 310 is integrally formed with the bottom plate 110 of the casing 10, but the invention is not limited thereto. In other embodiments, the positioning post 310 and the bottom plate 110 can be two separate components that are fixed.

The stopper 320 is disposed in the casing 10, and a portion of the circuit board 210 of the electronic component 20 is interposed between the bottom plate 110 of the casing 10 and the stopper 320. In detail, the stopper 320 may include a stop portion 321 and a limiting portion 322 connected thereto. The positioning module 30 has a stop surface 321a at the stop portion 321 , and the stop surface 321 a faces the bottom plate 110 . The circuit board 210 is interposed between the stop surface 321a and the bottom plate 110, and the top surface 211 of the circuit board 210 faces the stop portion 321 . The stopping portion 321 is disposed on the upper surface 311 of the positioning post 310 , and the limiting portion 322 extends from one side of the stopping portion 321 toward the bottom plate 110 of the casing 10 , and the limiting portion 322 is disposed on one side of the circuit board 210 . The stopper 320 in this embodiment includes the stopping portion 321 and the limiting portion 322, but the invention is not limited thereto. In other embodiments, the stop may not include a stop.

The fastener 330 is fixed to the casing 10 in a fastening direction A toward the circuit board 210, and the stopper 320 is fixed to the casing 10 via the fastener 330. In detail, the fastener 330 is, for example but not limited to, a screw, and includes a body 331 and a clamping portion 332. The interposition portion 332 is located around the body 331 and extends away from the body 331. The body 331 passes through the stopping portion 321 of the stopper 320 in the fastening direction A, and is fastened to the bottom plate 110 by the fastening hole 312 of the upper surface 311 of the positioning post 310, while the stopper 320 is fastened via the fastener 330. It is fixed to the bottom plate 110. Further, when the fastener 330 is locked to the fastening hole 312, the clamping portion 332 directly contacts the stopper portion 321 of the stopper 320, and the stopper portion 321 directly contacts the upper surface 311 of the positioning post 310, so that The clamping portion 332 and the positioning post 310 collectively sandwich the stopper portion 321 of the stopper 320. In the present embodiment, the stopper 320 and the fastener 330 are two independent components. This design helps to reduce the manufacturing cost, but the invention is not limited thereto. In other embodiments, the stop and the fastener can be integrally formed. For example, the interposed portion of the fastener may extend further away from the body to have a larger horizontal width, so that the interposed portion has a sufficient bottom area to serve as a stop surface.

Through the component arrangement described above, the circuit board 210 of the electronic component 20 can be moved relative to the casing 10 along the axial direction of the body 331 of the fastener 330. Thus, the circuit board 210 can be disposed on the stop surface 321a of the stopping portion 321 and the bottom plate 110. Adjust its position in the vertical direction. Detailed actions will be detailed later.

The rotating member 40 is, for example but not limited to, a volume adjusting knob, which sequentially passes through the opening 121 of the side plate 120 and the positioning hole 221 of the electronic component 220 from the outside of the casing 10. The rotating member 40 is rotatable relative to the electronic component 220 and the casing 10 with its own axis O1 as a center of rotation.

The technical means for solving the assembly problem of the rotary member 40 and the electronic component 220 by the electronic device 1 will be described below. Referring first to FIG. 1B, when the circuit board 210 and the electronic component 220 have no manufacturing tolerances, or the manufacturing tolerances are extremely small and negligible, the center of the positioning holes 221 is just aligned with the axis O1 of the rotating member 40. In this case, the rotary member 40 can smoothly and normally pass through the set hole 221, and the assembly of the rotary member 40 and the electronic component 220 is completed.

The following describes the case where the manufacturing tolerances of the circuit board 210 or the electronic component 220 are present. Please refer to FIG. 1C to FIG. 1D at the same time. 1C to FIG. 1D are schematic diagrams showing the operation of the rotary member of the electronic device of FIG. 1B.

As shown in FIG. 1C, the manufacturing tolerance of the electronic component 220 is illustrated as an example. Since the electronic component 220 has manufacturing tolerances, the center O2 of the positioning hole 221 and the axis O1 of the rotating member 40 have an offset S in the vertical direction. For existing manufacturing techniques, the offset S can be controlled to be within about 0.2 mm (millimeter, mm), and more often the offset S is about 0.1 mm.

Since there is an offset S between the positioning hole 221 and the rotating member 40, when the rotating member 40 passes through the positioning hole 221 of the electronic component 220, the rotating member 40 pushes against the sidewall of the electronic component 220 or the positioning hole 221. Inner wall. At this time, the interference of the rotating member 40 with the electronic component 220 gives the electronic component 220 an upward force. As shown in FIG. 1D, the upward force causes the circuit board 210 to move upward in the axial direction of the body 331 of the fastener 330, thereby aligning the axis O1 of the rotating member 40 with the center O2 of the positioning hole 221. Thereby, it is helpful to eliminate the offset S, and the rotating member 40 can smoothly and normally pass through the set hole 221, and the assembly of the rotating member 40 and the electronic component 220 is completed.

In the present embodiment, the stop 320 helps to limit the range of movement of the circuit board 210. In detail, when the circuit board 210 moves upward, the stopper portion 321 can prevent the circuit board 210 from excessively moving, so that the range of movement of the circuit board 210 in the vertical direction is limited between the stopper portion 321 and the bottom plate 110 of the casing 10. . In addition, since the circuit board 210 is not fixed to the casing 10, the circuit board 210 is still moved in the horizontal direction relative to the bottom plate 110, and the limiting portion 322 of the stopper 320 helps the circuit board 210 to be horizontal. The moving range is limited between the limiting portion 322 and the side plate 120 of the casing 10.

As shown in FIG. 1C and FIG. 1D, in the present embodiment, the spacing D between the stop surface 321a of the positioning module 30 and the bottom plate 110 is subtracted from the thickness of the circuit board 210 according to manufacturing tolerances that may occur in the prior art manufacturing technology. The value of T (DT) may be greater than or equal to 0.40 mm (mm) to help maintain the position of the circuit board 210 while providing the mobility of the circuit board 210. If the value of the pitch D minus the thickness T is less than 0.40 mm, the range of motion of the board 210 may be too small to compensate for manufacturing tolerances. Preferably, the average value of the manufacturing tolerance is considered, and the value of the pitch D minus the thickness T may be 0.20 mm or less.

The component configuration of another electronic device will be described below. Please refer to FIG. 2A and 2B. 2A-2B are schematic diagrams showing the operation of a rotary member of an electronic device according to a second embodiment of the present invention. Since the second embodiment is similar to the first embodiment, the following description will be made only on the difference. In this embodiment, the electronic device 1 further includes a conductive foam 50.

The conductive foam 50 is disposed between the bottom plate 110 of the casing 10 and the circuit board 210 of the electronic component 20. In the present embodiment, the conductive foam 50 is attached to the bottom surface 212 of the circuit board 210. In addition to helping to reduce electromagnetic interference, conductive foam 50 also helps to adjust the position of circuit board 210 in the vertical direction. In detail, the thickness of the conductive foam 50 can be appropriately designed such that the conductive foam 50 slightly lifts the circuit board 210 from the bottom plate 110 of the casing 10. Thereby, before assembling the electronic component 220 and the rotating component 40, the top surface 211 of the circuit board 210 and the stop surface 321a of the stopper 320 and the bottom surface 212 and the bottom plate 110 have a spacing d at the same time. When the center O2 of the positioning hole 221 of the electronic component 220 and the axis O1 of the rotating member 40 have an offset amount S in the vertical direction, the center O2 of the positioning hole 221 is higher or lower than the axis of the rotating member 40. O1, the circuit board 210 can move up or down in the axial direction of the body 331 of the fastener 330, and the axis O1 of the rotating member 40 is aligned with the center O2 of the positioning hole 221. In the present embodiment, the pitch d may be 0.20 mm, preferably 0.10 mm.

The electronic device of the above embodiment can be applied to a speaker device. Please refer to FIG. 3, which is a perspective view of a speaker apparatus according to a third embodiment of the present invention. In the present embodiment, the speaker device 2 may include the electronic device 1, an operation panel 3, and a speaker 4 of any of the foregoing embodiments. The speaker 4 is for example but not limited to a horn. The rotating member 40 of the electronic device 1 is an adjustment volume knob that is exposed.

In summary, in the speaker device and the electronic device disclosed in the present invention, the positioning module different from the prior art is to fix the circuit board to the casing, and the positioning module of the present invention is fixed to the casing, and the positioning module is fixed. The spacing between the stop faces of the set and the base plate is greater than the thickness of the circuit board. Thereby, the circuit board is floatingly disposed in the casing. Before the rotating component and the electronic component are assembled, the circuit board can move relative to the positioning module and the casing between the stopping surface and the bottom plate of the casing. When the rotating member penetrates the positioning hole of the electronic component, the rotating member gives a force to the electronic component, and drives the circuit board to move up and down to align the axis of the rotating member with the center of the positioning hole. Thereby, when the circuit board or the electronic component has manufacturing tolerances, the position of the circuit board can be adjusted to maintain a good assembly between the rotating member and the electronic component.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. It is within the scope of the invention to be modified and modified without departing from the spirit and scope of the invention.
