Description

Technical Field

[0001] This utility model relates to the field of tuning equipment technology, specifically to an intelligent tuner with dual microphones controlled by a touch-controlled miniLED screen. Background Technology

[0002] In the field of string instrument calibration, existing tuners mostly use a single buzzer vibration pickup or microphone pickup, which cannot automatically switch and adapt to the environment. They also rely on fixed clips, making it difficult to complete instrument calibration after removing the clips, thus limiting their use cases. In addition, traditional tuners lack touch functionality for power on / off selection, resulting in insufficient ease of operation. Furthermore, the display uses a black and white LCD screen without color display and has a poor viewing angle, affecting the user's ability to read information such as pitch and tone. This makes it difficult to meet users' needs for intelligent, convenient, and visual tuners.

[0003] As string instrument enthusiasts increase their demands for tuner performance, the market urgently needs a tuner that can adapt to different environments, operate more intelligently, and display more clearly. However, existing technologies have not solved the problems of automatic environment adaptation for dual pickups and calibration without clips, nor have they made breakthroughs in structural designs such as touch control and color display, thus failing to provide users with a better tuning experience. Therefore, providing a new type of tuner with functions such as touch control, dual pickup adaptation, and color digital display is of high practical value. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-6This utility model provides a technical solution: a touch-controlled miniLED screen dual-pickup intelligent tuner, including a housing 100, inside which a circuit board 110 is placed. The surface of the circuit board 110 is provided with a miniLED lamp array 111 of various colors for digital display. The bottom of the circuit board 110 integrates a vibrating buzzer 112 and a microphone 113 for sound pickup. The top of the circuit board 110 is provided with an upper housing 120, and the bottom of the upper housing 120 is fixedly connected with multiple shielding pillars 121. The middle of the shielding pillars 121 has an opening that connects to the miniLED screen. The LED lamp bead array 111 has light guide holes 122 corresponding to the lamp beads. Multiple studs 123 are fixedly connected to the bottom edge of the upper housing 120. The bottom of the outer housing 100 is provided with a bottom housing 130. Multiple screw holes 131 are opened on the edge of the bottom housing 130. The screw holes 131 are fixedly connected to the studs 123 by screws, so that the bottom housing 130 can be clamped and fixed with the upper housing 120, the outer housing 100 and the circuit board 110. The top of the circuit board 110 is also provided with a panel 140 fixedly connected to the top of the outer housing 100. The surface of the panel 140 is equipped with touch buttons 141 with multiple control functions.

[0023] Specifically, when a user needs to calibrate a stringed instrument such as a guitar, the sound waves or vibrations generated by the player plucking the strings are simultaneously captured by the vibrating buzzer 112 and the microphone 113 at the bottom of the circuit board 110. The dual pickup structure works together to transmit the signal to the processing unit. The user selects the function through the touch button 141 on the surface of the panel 140. After the operation signal is transmitted, the processing unit controls the miniLED light bead array 111 to display the corresponding string name and pitch. Different colored LED beads can intuitively reflect the pitch status. The shield post 121 of the upper housing 120 accurately guides the light from the miniLED light beads through the light guide hole 122 to avoid interference and ensure clear display. The bottom housing 130 is fixed to the upper housing 120 through the screw hole 131 and the stud 123 of the upper housing 120, firmly clamping the circuit board 110 inside the outer housing 100, ensuring that each component works stably in the vibrating environment of the instrument and achieving accurate tuning.

[0024] In this embodiment: a pickup hole 150 is provided on the side of the outer shell 100, and the outer shell 100 is made of metal.

[0025] Specifically, when a user uses the tuner in a noisy environment, the pickup hole 150 on the side of the housing 100 can enhance the microphone 113's ability to capture external sound waves. The metal housing 100 not only provides solid protection for the internal components and reduces the impact of external collisions on the circuit board 110, but also reduces the interference of external electromagnetic interference on the pickup signal. When the performer holds the tuner close to the instrument, the metal housing can quickly transmit the instrument's vibration to the vibrating buzzer 112. Combined with the sound signal transmitted through the pickup hole 150, the dual pickup system can still accurately obtain pitch information in complex environments, improving tuning stability.

[0026] In this embodiment, a charging opening 132 is provided at the bottom of the bottom shell 130, and the charging opening 132 is positioned opposite to the charging base 114 integrated at the bottom of the circuit board 110.

[0027] Specifically, when the tuner's battery is low, the user can connect the charging cable to the charging socket 114 at the bottom of the circuit board 110 through the charging opening 132 at the bottom of the bottom shell 130 to obtain power.

[0028] In this embodiment: the surface of the circuit board 110 is also integrated with an MCU microcontroller 115 and a power management chip 116. The touch button 141 is electrically connected to the MCU microcontroller 115. The power management chip 116 is electrically connected to the battery 170 inside the housing 100. The power management chip 116 is also typically connected to the MCU microcontroller 115. The MCU microcontroller 115 is electrically connected to the miniLED lamp array 111, the vibration buzzer 112, and the microphone 113.

[0029] Specifically, during performance, the touch button 141 on the user control panel 140 transmits signals to the MCU microcontroller 115 on the circuit board 110. The MCU microcontroller 115 coordinates the operation of various components according to instructions. Among them, it drives the miniLED lamp array 111 to display corresponding information, switches the pickup mode of the vibration buzzer 112 and the microphone 113, and the power management chip 116 is responsible for managing the power of the battery 170 inside the casing 100. While ensuring stable power supply to various components, it feeds back the power information to the MCU microcontroller 115. When the power is too low, it prompts the user to charge through the miniLED lamps, realizing intelligent power management and function control.

[0030] In this embodiment: a clamping mechanism 200 is sleeved on the outside of the outer shell 100. The clamping mechanism 200 includes a base 210 sleeved on the outside of the outer shell 100. A protrusion 220 is fixedly connected to the bottom of the base 210. A hinge 240 is rotatably connected to the protrusion 220 through a damping pin 230. A clip 250 is connected to the hinge 240 through a rotating shaft.

[0031] Specifically, when a user needs to fix the tuner to an instrument such as a guitar, the clip 250 is first used to fix the tuner to the instrument. The base 210 is used to securely hold the outer shell 100 to prevent the tuner from slipping. The protruding seat 220 and the hinge seat 240 are connected by a damping pin 230, allowing the user to rotate and adjust the angle of the tuner for easy observation of the miniLED display content.

[0032] If handheld use is required, loosen the clip 250, and the hinge 240 can rotate around the damping pin 230 to retract and remove the tuner without affecting handheld operation. This allows the tuner to be used both fixed on the instrument and handheld, adapting to different performance scenarios and improving the flexibility of use.

[0033] The contents not described in detail in this description are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
