Description

Technical Field

[0001] The present invention relates to a tuner for tuning a guitar and a system including a tuner, and more particularly to a tuner and system that obtains power from a preamplifier. Background Technology

[0002] A tuner is an electronic device in musical instruments such as guitars that provides the information needed for tuning based on the vibration frequency of the sound actually produced by the instrument.

[0003] In the existing technology, tuners used for tuning guitars are usually temporarily fixed to the headstock of the guitar, or integrally molded with the guitar and installed on one side of the guitar body, so that the tuner's display is exposed, which appears to be an unnecessary exposure.

[0004] At the same time, existing tuners, as stand-alone electronic devices, typically require a separate battery dedicated to the tuner, thus inevitably creating the problem of replacing or managing these dedicated batteries. Summary of the Invention

[0005] The problem the invention aims to solve

[0006] The present invention provides a tuner installed inside a guitar that receives power from a preamplifier, thus eliminating the need for a separate battery or power supply system.

[0007] The present invention provides a tuner that is installed inside a guitar, but whose display is visible to the player through the sound hole, thereby providing tuning information without damaging the guitar's appearance.

[0008] The present invention provides a tuner installed inside a guitar that receives power from a preamplifier, thus eliminating the need for a separate battery or power supply system.

[0009] This invention provides a system that saves power consumption without compromising the appearance by combining a tuner, preamplifier, and battery unit installed inside a guitar into a single power supply system.

[0010] The objectives of this invention are not limited to the foregoing description. Other objectives and advantages of this invention not mentioned can be understood from the following description, and will become clearer through embodiments of this invention. Furthermore, the objectives and advantages of this invention can be achieved through the methods and combinations thereof described in the claims.

[0011] Problem Solving Methods

[0012] A tuning system according to an embodiment of the present invention includes: a tuner mounted on the inside of the front panel of a guitar body and providing tuning information; and a preamplifier mounted on the inside of the front panel, amplifying the sound produced by the guitar and transmitting it to an external device. The tuner is connected to and receives power from the preamplifier.

[0013] The tuner includes: a sensor for detecting vibrations of the front panel; and a display for identifying the frequency of the sound based on the detected vibrations and providing tuning information.

[0014] At this time, the tuner, for ease of playing, is installed below the soundhole formed on the front panel of the guitar body, with the guitar held horizontally upright as a reference. A significant portion of the tuner is concealed on the front of the guitar, making it invisible through the soundhole. Furthermore, the display, for ease of playing, is oriented upwards with the guitar held horizontally upright as a reference, so that it can be displayed to the player when they are holding the guitar and looking down into the soundhole.

[0015] On the other hand, when the saddle formed on the front part vibrates based on the sound produced by the guitar, the preamplifier acquires a first audio signal based on the piezoelectric effect of the piezoelectric element included in the pickup sensor; acquires a second audio signal matching the sound produced by the guitar through a microphone; and generates an amplified audio signal based on the first and second audio signals.

[0016] In this case, the tuner includes a display that provides tuning information; the preamplifier transmits the vibration frequency data of the sound detected by the corresponding pickup sensor to the tuner; and the tuner displays the tuning information obtained based on the data through the display.

[0017] On the other hand, the tuner can switch its power on and off according to the user's operation of the buttons provided on the tuner; during the power-on period of the tuner, at least one control signal for disabling the amplification function of the preamplifier is transmitted to the preamplifier.

[0018] In addition, the tuner automatically shuts off its power after the tuner is powered on and a certain period of time has elapsed.

[0019] The preamplifier draws power from a battery attached to the guitar or at least one external device.

[0020] A tuning system according to an embodiment of the present invention includes: a tuner mounted on the inside of the front panel of a guitar body and providing tuning information; a preamplifier mounted on the inside of the front panel, amplifying the sound produced by the guitar and transmitting it to an external device; and a battery unit supplying power to the preamplifier. The tuner is connected to and receives power from the preamplifier.

[0021] The battery unit includes: a power supply unit comprising a battery compartment with at least one replaceable battery; and a connection unit connected to the preamplifier and the external device, respectively. Furthermore, the audio signal output from the preamplifier can be output to the external device via the connection unit.

[0022] Invention Effects

[0023] According to the present invention, the tuner and system are mounted on the inside of the front panel near the sound hole, thereby limiting the exposure of the tuner and preamplifier to the outside while ensuring that the tuning information is visible to the performer.

[0024] Furthermore, the tuner according to the present invention obtains power from the preamplifier, eliminating the need for separate batteries or the like, thus unifying the power supply source of the electronic devices attached to the guitar into one, thereby facilitating management.

[0037] Before describing the invention in detail, the description method of this specification and the accompanying drawings will be introduced first.

[0038] First, the terminology used in this specification and claims is general terminology considering the functional choices in various embodiments of the invention. However, these terms may vary depending on the intent of those skilled in the art, legal or technical interpretations, and the emergence of new technologies. Furthermore, some terms are arbitrarily chosen by the applicant. These terms may be interpreted as defined in this specification, or, in the absence of specific term definitions, may be interpreted based on the overall content of this specification and common technical knowledge of those skilled in the art.

[0039] Furthermore, the same reference numerals and symbols used in the various figures of this specification denote parts or components that actually perform the same function. For ease of description and understanding, the same reference numerals or symbols are used in different embodiments. That is, even if components with the same reference numerals are shown in multiple figures, the multiple figures do not represent a single embodiment.

[0040] Furthermore, terms containing ordinal numbers, such as "first," "second," etc., may be used in this specification and claims to distinguish different components. These ordinal numbers are used to distinguish identical or similar components, and the meaning of the terms is not limited by the ordinal numbers used. As an example, the order of use or arrangement of components combined with these ordinal numbers is not limited by the numbers used. The ordinal numbers may also be used interchangeably as needed.

[0041] Where there is no obvious distinction in the context, the singular usage used in this specification includes the meaning of the plural. In this application, terms such as "comprising" or "possessing" indicate the presence of the features, numbers, steps, actions, structures, components, or combinations thereof described in the specification, rather than precluding the existence or additional possibility of one or more other features, numbers, steps, actions, structures, components, or combinations thereof.

[0042] In embodiments of the present invention, terms such as "module," "unit," and "part" refer to components that perform at least one function or action. These components can be implemented in hardware or software, or a combination of hardware and software. Furthermore, multiple "modules," "units," and "parts" can be integrated into at least one module or chip and implemented by at least one processor, unless each needs to be implemented as separate, specific hardware.

[0043] Furthermore, in embodiments of the present invention, when describing the connection between one part and another part, it includes not only direct connection but also indirect connection through other media. In the specification, when it is stated that a part "comprises" a component, unless otherwise stated, it does not exclude other components but may also include them.

[0044] Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] Figure 1 This is a schematic diagram of the general structure of a guitar according to an embodiment of the present invention, and a system including a tuner and a preamplifier installed inside the guitar.

[0046] See Figure 1 A typical guitar consists of a body, a neck, and a headstock. The strings starting from the body connect to the neck via the bridge and extend to the headstock. Sound enters the body through the soundhole formed on the front panel.

[0047] See Figure 1 The tuner 100 and the preamplifier 200 can be installed inside the guitar body.

[0048] Tuner 100 is an electronic device that provides tuning information based on the vibration frequency of the sound produced by the guitar, and can be installed on the inside of the front panel of the guitar body.

[0049] The preamplifier 200 is an electronic device that amplifies the sound produced by the guitar and transmits it to external devices (such as amplifiers, speakers, headphones, headsets, etc.), and can also be installed on the inside of the front panel of the guitar body.

[0050] In this invention, the tuner 100 is connected to the preamplifier 200 and receives power from the preamplifier 200, thus eliminating the need for a separate battery. Although the preamplifier 200 does not directly participate in tuning the guitar, since it is connected to and powers the tuner 100, the tuning system according to this invention can be defined as including the tuner 100 and the preamplifier 200.

[0051] The specific structure of the tuner 100 and the preamplifier 200 will be described in detail below with reference to the accompanying drawings.

[0052] Figure 2 This is a block diagram of the various structures of a tuner and a preamplifier according to various embodiments of the present invention.

[0053] See Figure 2 The tuner 100 may include at least one of a sensor 110, a display 120, a control unit 130, and a user input unit 140.

[0054] Sensor 110 is configured to detect the vibration frequency of the sound produced by the guitar. This can be achieved through contact vibration sensors, displacement sensors, acceleration sensors, etc., but is not limited to these.

[0055] As an example, sensor 110 can detect vibrations near the front panel of the guitar body, thereby identifying the vibration frequency of the sound. For instance, when the outer side of one side of tuner 100 contacts the inner side of the guitar's front panel, sensor 110 identifies the vibration frequency of the guitar's front panel by contacting the inner side of that side of tuner 100. Alternatively, sensor 110 may be formed directly to contact the guitar's front panel. On the other hand, sensor 110 may not be included in the body of tuner 100, but may be installed on the outside of tuner 100 via a wired connection, for example, it may be spaced apart from tuner 100 and attached to at least a portion of the guitar's front panel.

[0056] In this case, only the vibration of the front panel corresponding to the guitar's own sound can be accurately measured, without being affected by surrounding noise, thus ensuring the accuracy of tuning.

[0057] The display 120 is configured to identify the frequency of the detected sound and provide tuning information, displaying the information in a visual form. The tuning information may include pitch information matching the detected frequency, information on the difference between the detected frequency and at least one pitch, etc.

[0058] The display 120 can be implemented using LCD (Liquid Crystal Display), PDP (Plasma Display Panel), OLED (Organic Light Emitting Diodes), TOLED (Transparent OLED), Micro LED, etc., but is not limited to these, and may also include various other known displays. The display can be implemented as a touch screen capable of detecting user touch operations, or as a flexible display that can be folded or bent.

[0059] The control unit 130 is configured to control the overall setup of the tuner 100. The control unit 130 may be implemented by at least one control circuit or integrated circuit, or may include at least one processor.

[0060] As an example, when sensor 110 detects the vibration of the guitar's front panel near the guitar body, control unit 130 can identify the frequency of the sound based on the detected vibration frequency, generate tuning information, and control display 120 to display the generated tuning information.

[0061] The user input unit 140 is configured to receive various commands or information input by the user. The user input unit can be implemented through at least one button, joystick, touchpad, touch screen, sensor, etc.

[0062] Specifically, the user input section 140 may include at least one button for switching the power supply of the tuner 100 on or off.

[0063] See Figure 2 The preamplifier 200 may include at least one of a microphone 210, a pickup sensor 220, an amplification control unit 230, a user input unit 240, and a display 250.

[0064] The microphone 210 is configured to receive the sound of a guitar and may include at least one circuit that converts the vibrations of sound waves into electrical signals. The microphone 210 may also be built into the body of the preamplifier 200, or it may be formed to be attached to the body of the preamplifier 200 but protrude outwards. Alternatively, the microphone 210 may be formed separately from the body of the preamplifier 200, while being wired to the body of the preamplifier 200 to transmit audio signals.

[0065] The pickup sensor 220 is a sensor attached to or mounted near the saddle (e.g., indirectly detecting vibrations via at least one other board) to detect other sounds. Specifically, the pickup sensor 220 may include a piezoelectric sensor or piezoelectric element, in which the vibration of the guitar strings causes the vibration of the saddle to produce a piezoelectric effect within the pickup sensor 220, thereby generating an electrical signal converted from the sound of the guitar.

[0066] When the preamplifier 200 is installed near the soundhole, the pickup sensor 220 is installed in contact with the bridge but separated from the main body of the preamplifier 200, so the pickup sensor 220 and the preamplifier 200 can be connected by a wire. However, when the preamplifier 200 is installed near the bridge, the pickup sensor 220 can also be included within the main body of the preamplifier 200.

[0067] The amplification control unit 230 is configured to generate an audio signal for amplifying the sound of the guitar. The amplification control unit 230 may include at least one circuit, integrated circuit, or processor for amplifying the audio signal.

[0068] Specifically, the amplification control unit 230 can obtain an amplified audio signal using at least one of the audio signal acquired by the microphone 210 and the frequency detected by the pickup sensor 220.

[0069] See Figure 2 The amplification control unit 230 can control the Blend module 231, Clarity module 232, Phase module 233, etc. These modules are functional units composed of software and / or hardware.

[0070] The blend module 231 is configured to mix a first audio signal acquired by the pickup sensor 220 and a second audio signal acquired by the microphone 210. Specifically, the blend module 231 can mix the first and second audio signals according to a ratio set by the user input to generate an amplified audio signal. In this case, the ratio can be set to 100% for only one of them; for example, when the first audio signal is set to 100%, only the first audio signal acquired by the pickup sensor 220 is amplified.

[0071] As an example, the Blend module 231 generates an audio signal amplified based on the first audio signal, and changes the mixing ratio of the second audio signal according to user input to achieve mixing.

[0072] Clarity module 232 is configured for filtering audio signals. For example, Clarity module 232 can emphasize or weaken audio signals of specific frequencies / ranges based on user input, and filtering functions can be implemented through various settings.

[0073] Phase module 233 is configured to change the phase of the audio signal. Relatedly, the audio signal amplified by preamplifier 200 is output through at least one external device (e.g., a speaker) and input through the microphone 210 of preamplifier 200, which can cause a phenomenon where the phase of the guitar sound overlaps with the amplified sound (e.g., howling). Phase module 233 can prevent this phenomenon from occurring by changing the phase of the audio signal.

[0074] The user input unit 240 is configured to acquire various user commands related to the amplification of audio signals. The user input unit can be implemented via at least one button, joystick, touchpad, touch screen, sensor, etc.

[0075] Specifically, the user input unit 240 can acquire user input that sets the blending ratio related to the function of the Blend module 231, user input that activates the function of the Clarity module 232, user input that activates the function of the Phase module 233, and user input that controls the volume of the audio signal, etc.

[0076] Display 250 is configured to visually provide various information related to the operation of preamplifier 200. Display 250 may be implemented using LCD (Liquid Crystal Display), PDP (Plasma Display Panel), OLED (Organic Light Emitting Diodes), TOLED (Transparent OLED), Micro LED, etc., but is not limited to these, and may also include various other known displays.

[0077] Specifically, the display 250 can display the battery status of the preamplifier 200, or the battery status of the battery unit that supplies power to the preamplifier 200. The battery status may include the battery charge level, remaining time, etc. On the other hand, as a means of indicating the remaining battery level, it may also include only a few light-emitting elements and not the display 250.

[0078] In addition, the display 250 can show the settings of various functions (Blend, Clari ty, Phase) (e.g., Blend ratio, Volume), whether the function is activated or not, and other information.

[0079] Figure 3a This refers to a tuner according to an embodiment of the present invention, and the tuning information displayed by the tuner.

[0080] See Figure 3aThe tuner 100 may include a power switch button 140' and a display 120. When the power is on, the display 120 can show pitch information corresponding to the frequency of the guitar sound. For this purpose, the vibration frequency of the front panel of the guitar body can be detected by the sensor 110 of the tuner 100.

[0081] As an example, see Figure 3a According to reference numeral 310, the tuner 100 can display on the display 120 the pitch (e.g., A) closest to the currently detected frequency. If the actual frequency is lower than the pitch, an arrow is added to the left of the pitch (e.g., A) and the screen is displayed in white. If the pitch is exactly the same as the actual frequency, the screen is displayed in green. If the actual frequency is higher than the pitch, an arrow is added to the right of the pitch (e.g., A) and the screen is displayed in white.

[0082] Tuning information is provided via display 120, allowing the user (performer) to tune the instrument.

[0083] on the other hand, Figure 3b This is a schematic diagram of the appearance of a preamplifier according to an embodiment of the present invention.

[0084] See Figure 3b The preamplifier 200 may include a microphone 210, a rotary switch 241 for setting the blend ratio, a button 242 for activating / deactivating the Clarity function, a button 243 for enabling / deactivating the Phase change function, a rotary switch 244 for setting the volume, etc., and may also include a display 250 for displaying information related to battery charging.

[0085] The preamplifier 200 can obtain power from a battery attached to the guitar or at least one external device. For example, the display 250 can display information related to the charging of a battery attached to the guitar and connected to the preamplifier 200 via a wired connection to supply power. Specifically, the display 250 can output light (e.g., an LED) indicating that the battery level is below a certain value. Alternatively, the display 250 can display the battery level as a percentage. In this case, the battery supplies power to the preamplifier 200, which in turn supplies power to the tuner 100.

[0086] Figure 4a This is a schematic diagram showing the arrangement and connection relationship of a tuner and a preamplifier installed inside a guitar according to an embodiment of the present invention. Figure 4a This is a view of the inner side of the front panel corresponding to the inside of the instrument body, viewed from the rear to the front.

[0087] See Figure 4aThe tuner 100 and preamplifier 200 can be mounted on the inside of the front panel of the guitar body, depending on the shape of the soundhole. Therefore, when the soundhole is viewed from the front of the guitar, the tuner 100 and preamplifier 200 can each be partially or completely obscured.

[0088] See Figure 4a The preamplifier 200 is wired to the tuner 100 via cable 401, thereby supplying power to the tuner 100.

[0089] In addition, the preamplifier 200 is connected to the pickup sensor 220 via cable 406, thereby acquiring the audio signal generated by the bridge.

[0090] On the other hand, the preamplifier 200 can transmit the frequency data of the sound detected by the pickup sensor to the tuner 100 via cable 401. In this case, the tuner 100 can display the tuning information obtained based on the data (frequency) received from the preamplifier 200 via display 120. At this time, the tuner 100 does not need to be equipped with or use the sensor 110 for detecting sound frequencies itself, and can provide tuning information based on the detection results of the preamplifier 200.

[0091] In this regard, as an embodiment, the tuner 100 may periodically deactivate the sensor 110 based on a comparison between a first frequency detected by the sensor 110 and a second frequency detected by the pickup sensor 220 of the preamplifier 200.

[0092] Specifically, during the detection of a guitar sound, tuner 100 can compare a first frequency detected by sensor 110 with a second frequency detected by pickup sensor 220 within a first time period. Within the first time period, tuner 100 can provide tuning information based on the first frequency detected by sensor 110.

[0093] If all comparison results are consistent within the first time period, the tuner 100 can deactivate the sensor 110 in the subsequent second time period. In this case, during the second time period, the tuner 100 can provide tuning information based on the second frequency detected by the pickup sensor 220 of the preamplifier 200.

[0094] Furthermore, after the second time period, the tuner 100 can again compare the first frequency detected by the sensor 110 with the second frequency detected by the pickup sensor 220 within the first time period. Similarly, if the comparison results are all consistent, the sensor 110 is deactivated again within the second time period, and tuning information is provided based on the second frequency detected by the pickup sensor 220.

[0095] Accuracy can be ensured by periodically checking whether the frequencies detected by sensor 110 and pickup sensor 220 are consistent. When the frequencies are determined to be consistent, sensor 110 and pickup sensor 220 are not activated simultaneously; instead, only pickup sensor 220 is activated to provide tuning information, thereby achieving the same tuning effect while reducing power consumption. In particular, in embodiments of the invention where the tuner 100 receives power from preamplifier 200, this can be understood as a reduction in the amount of power consumed jointly.

[0096] In addition, to further reduce power consumption, the first time can be relatively shorter than the second time.

[0097] On the other hand, if the comparison result shows a discrepancy at least for a portion of the first time period, the tuner 100 can keep the sensor 110 active. In this case, the tuner 100 can still provide tuning information based on the first frequency detected by the sensor 110 during a second time period following the first time period. Furthermore, the tuner 100 can also output a warning message on the display 120, indicating a discrepancy between the first frequency detected by the sensor 110 and the second frequency detected by the pickup sensor 220. In this case, the screen may be displayed in red, but is not limited to this. Therefore, the user can detect a problem with the frequency detection function of at least one of the tuner 100 and the preamplifier 200 and take appropriate measures.

[0098] On the other hand, see Figure 4a One side of the tuner 100 and the preamplifier 200 can be formed as a curved surface to adapt to the circular edge of the sound hole, thus limiting the exposure of the tuner 100 and the preamplifier 200 through the sound hole when the guitar is viewed from the front.

[0099] In this regard, Figure 4b This is a schematic diagram of the shape of a tuner and a preamplifier that are formed to match the shape of the sound hole and are partially exposed according to an embodiment of the present invention.

[0100] See Figure 4b The exposed surfaces of the tuner 100 and the preamplifier 200 are each formed as curved surfaces, which not only harmonizes with the design of the soundhole, but also significantly limits their exposure when the guitar is viewed from the front.

[0101] Figure 5a This is a schematic diagram showing the shape of a preamplifier installed inside a guitar according to an embodiment of the present invention, as viewed from below the front through the sound hole.

[0102] See Figure 5aFor ease of playing, with the guitar held horizontally upright, the preamplifier 200 can be mounted above the soundhole formed on the front panel of the guitar body. Here, a significant portion of the preamplifier 200 is concealed, making it invisible from the front of the guitar through the soundhole. Figure 5a As shown, when viewed from the front bottom, various buttons (e.g., 241, 242, 243, 244, etc.) are visible.

[0103] Figure 5b This is a schematic diagram showing the shape of a tuner installed inside a guitar according to an embodiment of the present invention, as viewed from above through the sound hole.

[0104] See Figure 5b For ease of playing, with the guitar held horizontally upright as a reference, the tuner 100 can be installed below the soundhole formed on the front panel of the guitar body. Here, the tuner 100 is partially concealed, so it is not visible from the front of the guitar through the soundhole, but... Figure 5b As shown, when viewed from the front and above, the display 120 and buttons 140' are visible.

[0105] That is, the display 120 of the tuner 100 is set facing upwards so that, for ease of playing, based on the guitar being held horizontally upright, the inside of the sound hole can be observed from above when the player holding the guitar looks down.

[0106] Furthermore, as one embodiment, the tuner 100 can switch its power on and off based on the user's operation of the button 140' provided on the tuner 100. Additionally, during the power-on period of the tuner 100, the tuner 100 can send at least one control signal to the preamplifier 200 to deactivate the preamplifier 200's amplification function. At this time, the control signal can be transmitted via the cable 401, or via other cables or wireless communication.

[0107] Therefore, the preamplifier 200 is deactivated during the operation of the tuner 100, thereby preventing the amplification and output of sound during the tuning process.

[0108] Furthermore, as an embodiment, the tuner 100 can be designed to automatically turn off the power after the tuner 100 is powered on and a certain period of time has elapsed. Specifically, if the control unit 130 does not detect vibration and frequency through the sensor 110 within a certain period of time (e.g., 7 minutes), it can automatically turn off the power.

[0109] Furthermore, as an example, when the power supply of the tuner 100 is turned on and the preamplifier 200 is in a deactivated state, if the power supply of the tuner 100 is turned off due to the user operating the button 140' or after a certain period of time, the tuner 100 may send at least one control signal to the preamplifier 200 before the power supply is turned off to reactivate the amplification function of the preamplifier 200.

[0110] On the other hand, in addition to the tuner 100 and the preamplifier 200, the system according to an embodiment of the present invention may also include a battery unit 300.

[0111] In this regard, Figure 6 This is a schematic diagram of the general structure of a guitar according to an embodiment of the present invention, and a system including a tuner, a preamplifier, and a battery unit installed inside the guitar.

[0112] See Figure 6 The tuner 100, preamplifier 200, and battery unit 300 can be installed inside the guitar body.

[0113] The battery unit 300 is configured to supply power to the preamplifier 200. The battery incorporated in the battery unit 300 can be a replaceable battery or a rechargeable battery. In the rechargeable case, when the battery is connected to the battery unit 300, at least one terminal of the battery unit 300 is wired to an external charging device for charging; or when the battery is disconnected from the battery unit 300, it can be charged on an external charging device.

[0114] The battery unit 300 may also include at least one connection means (e.g., connection terminal, cable, etc.) for transmitting the amplified audio signal from the preamplifier 200 to an external device.

[0115] The preamplifier 200 not only amplifies the sound of the guitar using the power supplied by the battery section 300, but can also transmit some of the power to the tuner 100.

[0116] That is, in this invention, the battery unit 300 supplies power to the preamplifier 200, and the preamplifier 200 can supply power to the tuner 100. In this case, the tuner 100 does not need to have its own battery.
