Description

Technical Field

[0001] This utility model belongs to the field of karaoke equipment, and in particular relates to a karaoke remote control without button sounds. Background Technology

[0002] When using a karaoke remote or traditional microphone for karaoke, the buttons on these devices are typically mechanical. Because mechanical buttons produce a clicking sound when pressed and have a stiff feel, these sounds are easily picked up by the sound capture unit and amplified through the TV speakers, degrading the user experience. Furthermore, mechanical buttons are prone to wear and tear and damage, affecting the device's lifespan. Additionally, traditional mechanical buttons suffer from inconsistent tactile feedback and difficulties in structural assembly design.

[0003] In addition, due to the product characteristics of karaoke remote controls, there are interactive operations such as adjusting volume, switching tracks, and adjusting accompaniment when singing karaoke, so the demand for not having button sounds is very strong; and the remote control's buttons are used frequently, so the lifespan of the buttons is also very important.

[0004] Of course, in existing technologies, mechanical buttons can be replaced with silicone buttons. However, silicone buttons can only reduce, not completely eliminate, the key noise. Furthermore, due to the inherent characteristics of silicone buttons, they are easily damaged during microphone assembly and disassembly. Once damaged, they can only be replaced on the PCBA, impacting production efficiency and increasing costs. Another approach is to use plastic buttons with a lower tactile feel and cover the top with a silicone sleeve for cushioning and noise reduction. However, noise still exists, the key noise cannot be eliminated, and the increased assembly steps further increase costs. Modifications to the microphone pickup module, such as adding sound-absorbing cotton, can prevent the sound acquisition unit from picking up the key noise, thus achieving the effect of eliminating it. However, these methods are not effective at eliminating key noise and increase material and assembly costs within the existing microphone design. Utility Model Content

[0005] The technical objective of this invention is to provide a karaoke remote control without button sounds, thereby solving the problem that button noise is picked up by the microphone unit and amplified in the external speaker, thus optimizing the product experience.

[0006] To solve the above problems, the technical solution of this utility model is as follows:

[0007] A keyless karaoke remote control, comprising:

[0008] The housing has a pressure-sensitive area, which is divided into several pressing units.

[0009] The PCB motherboard is housed within the casing.

[0010] The pressing unit is a housing pressing button, which is arranged sequentially on the housing, and the button area is mechanically connected to the pressure sensor.

[0011] At least two pressure sensors are provided, with their two ends connected to the pressure-sensitive area of ​​the housing and the PCB motherboard, respectively, and electrically connected to the PCB motherboard.

[0012] Press the pressure-sensitive area of ​​the outer shell. The process remains silent during the pressing. The pressure-sensitive area of ​​the outer shell deforms when pressed, and the pressure sensor generates a corresponding pressure signal in sync with the downward pressure. The PCB motherboard is used to process the pressure signal to generate corresponding control commands.

[0013] More preferably, a support pad is also provided, which is disposed between the pressure sensor and the pressure-sensitive area of ​​the housing, for fixing and supporting the pressure-sensitive area of ​​the housing when pressed.

[0014] The pressure sensor includes a sensor support and a sensing unit.

[0015] The sensing unit is mounted on the PCB motherboard and is electrically connected to the PCB motherboard.

[0016] One end of the sensor support is connected to the sensing unit, and the other end of the sensor support is fixed with a support pad.

[0017] The PCB motherboard contains a control unit that is connected to a pressure sensor to collect pressure signals. The pressure signals include press position information. Based on the press position information, the position of the pressed button on the outer shell is determined, which is then converted into a corresponding control signal and output to control external devices to perform corresponding operations.

[0018] The pressure-sensitive area on the outer shell replaces the traditional mechanical buttons.

[0019] Specifically, the button unit includes power on / off buttons, volume control buttons, directional control buttons, track skipping button, pause button, and mute button.

[0020] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:

[0021] This invention replaces traditional mechanical buttons with a pressure sensor and a pressure-sensitive area on the outer shell of a karaoke remote control. In terms of structural design, only a bracket is needed to press the pressure-sensitive area of ​​the outer shell onto the pressure sensor. The pressure sensor generates a pressure signal when pressed, and the collected pressure signal is converted into a corresponding control signal, which is then output to control external devices to perform corresponding operations. This solution is similar in effect to a touchscreen, but at a lower cost, fundamentally eliminating the button sounds during karaoke and improving the user experience. Attached Figure Description

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0029] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a karaoke remote control with no physical buttons according to this utility model. The advantages and features of this utility model will become clearer from the following description and claims.

[0030] Example

[0031] See Figure 1 and Figure 2This embodiment provides a karaoke remote control without physical buttons. Externally, the main body is a shell, i.e., the outer casing of the remote control. A pressure-sensitive area is provided on the control surface of the shell. This area is divided into several pressing units, the size, number, and position of which depend on the required button size, number, and layout of the remote control. The pressure-sensitive area is mechanically connected to a pressure sensor. Specifically, the touch unit is a shell pressing button 5, which is arranged within the pressure-sensitive area. It is worth noting that the shell pressing buttons 5 in this embodiment are not traditional buttons, but rather are individual buttons sprayed onto the pressure-sensitive area. Their actual button function relies on the pressure sensor.

[0032] See Figure 2 In this embodiment, from bottom to top, the components are a sensing unit 2, a sensor support 3, a support pad 4, and a housing press button 5. The sensing unit 2 is mounted on the PCB motherboard 1, and at least two sensing units 2 are provided and electrically connected to relevant circuits arranged on the PCB motherboard 1. One end of the sensor support 3 is connected to the corresponding sensing unit 2, and the other end of the sensor support 3 is fixed with the support pad 4. A housing pressure-sensitive area with the housing press button 5 is fixed above the support pad 4. The support pad 4 is used to fix and support the housing pressure-sensitive area, while adjusting the overall height of the button to ensure it can be pressed normally. Therefore, this embodiment detects the pressure change when the housing pressure-sensitive area is pressed to identify the housing press button 5 in a pressed state and generates a corresponding pressure signal to trigger the button to activate, serving as a source of control signals.

[0033] Therefore, in this embodiment, replacing the mechanical button with a pressure sensor and the outer casing pressing button 5 does not significantly change the hardware design. Furthermore, due to the inherent characteristics of the pressure sensor, it does not produce the rebound sound of a dome-type button, and no additional structural design is required; only the thickness of the support pad 4 needs to be adjusted according to the specific support column dimensions.

[0034] See Figure 1 Preferably, a control unit is arranged on the PCB motherboard 1. The control unit is connected to the pressure sensor signal. By collecting the pressure signal from the pressure sensor, the control unit can determine which button has been pressed, generate a corresponding control signal, and output the obtained control signal to control external devices (such as a television) to perform corresponding operations. Specifically, the button unit can be divided into power on / off buttons, volume adjustment buttons, directional control buttons, track skip buttons, pause buttons, and mute buttons according to their functions. After the main control unit recognizes the corresponding button after it is pressed, it converts it into corresponding power on / off signals, volume adjustment signals, directional control signals, track skip signals, pause signals, and mute signals.

[0035] Therefore, in actual use, when the user presses the outer casing press button 5, the support pad 4 and the sensor pillar 3 are subjected to a downward pressure and move downward. The sensing unit 2, squeezed by the sensor pillar 3, generates a corresponding pressure signal. This pressure signal contains the position information of the outer casing press button 5 under the corresponding pressed state (the coordinates of the pressed part are calculated by the sensing unit 2). Different position information corresponds to different button signals. After receiving the pressure signal, the control unit processes and analyzes it to determine which outer casing press button 5 is pressed. Based on this, it generates a corresponding control signal to control the external device to perform the corresponding operation.

[0036] Ideally, 3D Touch could also be incorporated into the button controls of the remote control to enrich the button interaction design and enhance the user experience. Specifically, users could perform basic functions by tapping, or by pressing hard or holding down, combined with relevant feedback mechanisms (vibration, alert sounds, etc.) to enrich the interaction of the karaoke remote control.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
