[0005]

[0001] The present disclosure relates to a tuner for tuning a guitar and a system including the tuner, and more particularly to a tuner provided to be powered from a preamp and a system.

Background Art

[0002] A tuner is an electronic device that provides information necessary for tuning based on the frequency of the sound actually produced by an instrument such as a guitar.

[0003] Conventionally, a tuner for tuning a guitar is generally temporarily fixed to the head of the guitar or attached to one side of the guitar body integrally with the guitar so that the display of the tuner is visible on the appearance of the guitar. In many cases, it is unnecessarily exposed in terms of appearance.

[0004] Furthermore, a conventional tuner is an independently operating electronic device, and generally requires a separate battery only for the tuner. There is a problem that replacement or management of the separate battery only for the tuner is inevitable.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present disclosure provides a tuner provided inside a guitar and powered from a preamp, so that a separate battery or a power supply system is not required.

[0006] The present disclosure provides a tuner provided inside a guitar, but formed so that the display is visible in the view of the player through the sound hole, and provides tuning information without impairing the appearance of the guitar.

[0007] This disclosure provides a tuner that is installed inside a guitar and is powered by a preamplifier, thus eliminating the need for a separate battery or power supply system.

[0008] This disclosure provides a system that is excellent in terms of power consumption while not compromising the appearance, by consisting of a single power supply system via a tuner, preamplifier, and battery unit located inside the guitar.

[0009] The purposes of this disclosure are not limited to those mentioned above, and other purposes and advantages of this disclosure not mentioned can be understood from the description below and will be further made clear from the embodiments of this disclosure. It will also be readily apparent that the purposes and advantages of this disclosure can be achieved by the means and combinations thereof expressed in the claims. [Means for solving the problem]

[0010] A tuning system according to one embodiment of the present disclosure includes a tuner provided inside the front panel of a guitar body to provide tuning information, and a preamplifier provided inside the front panel to amplify the sound generated by the guitar and transmit it to an external device. The tuner is connected to the preamplifier and power is supplied from the preamplifier.

[0011] The tuner may include a sensor for sensing vibrations of the front panel, and a display that identifies the sound frequency based on the sensed vibrations and provides tuning information.

[0012] In this case, the tuner is positioned below the soundhole formed in the front panel of the body, based on the guitar being held horizontally for the sake of playing, and a certain percentage or more of the tuner can be hidden so that it is not visible from the front of the guitar through the soundhole. The display can be oriented upwards so that it is visible to the performer when they are holding the guitar and looking downwards into the soundhole, based on the guitar being held horizontally for the sake of playing.

[0013] On the other hand, the preamplifier can also acquire a first audio signal by the piezoelectric effect of a piezoelectric element included in the pickup sensor when the saddle formed on the front of the guitar vibrates based on the sound generated by the guitar, acquire a second audio signal that matches the sound generated by the guitar via a microphone, and generate an amplified audio signal based on the first audio signal and the second audio signal.

[0014] In this case, the tuner may be equipped with a display that provides tuning information, the preamplifier transmits data for the frequency of sound vibrations sensed via the pickup sensor to the tuner, and the tuner may display the tuning information obtained based on the data via the display.

[0015] On the other hand, the tuner can be powered on or off by user operation of a button provided on the tuner, and while the tuner is powered on, it can send at least one control signal to the preamplifier to deactivate the amplification function of the preamplifier.

[0016] Furthermore, the tuner can also be configured to automatically shut off after a certain period of time has elapsed since it was powered on.

[0017] The preamplifier can be powered by a battery attached to the guitar or by at least one external device.

[0018] A tuning system according to one embodiment of the present disclosure comprises a tuner provided inside the front panel of a guitar body to provide tuning information, a preamplifier provided inside the front panel to amplify the sound generated by the guitar and transmit it to an external device, and a battery unit for supplying power to the preamplifier. The tuner is connected to the preamplifier and can be powered by the preamplifier.

[0019] The battery unit may include a power supply unit consisting of a battery box in which at least one battery can be replaced, a preamplifier, and connection parts for connecting to the external device, respectively. The audio signal output via the preamplifier can be output to the external device via the connection parts. [Effects of the Invention]

[0020] The tuner and system described herein are installed on the inside of the front panel adjacent to the sound hole, thereby limiting the exposure of the tuner and preamplifier to the outside while still allowing the tuning information to be visible to the performer.

[0021] Furthermore, the tuner described in this disclosure is powered by the preamplifier and does not require a separate battery, thus having the advantage of unifying the power supply source for electronic devices attached to the guitar into a single source, making management convenient.

Mode for Carrying Out the Invention

[0023] Before providing a detailed description of this disclosure, we will first explain the method of describing this specification and the drawings.

[0024] First, the terms used in this specification and in the claims have been selected as general terms considering their function in the various embodiments of this disclosure. However, such terms may change depending on the intent of the articulators, legal or technical interpretations, and the emergence of new technologies. In addition, some terms have been arbitrarily selected by the applicant. Such terms may be interpreted as having the meaning defined herein, or, if there is no specific definition, may be interpreted based on the general content of this specification and common technical knowledge in the art.

[0025] Furthermore, the same reference numerals or symbols in each of the drawings attached to this specification indicate parts or components that perform substantially the same function. For the sake of explanation and understanding, the same reference numerals or symbols are used to describe different embodiments. That is, even if components with the same reference numeral are all illustrated in multiple drawings, the multiple drawings do not represent a single embodiment.

[0026] Furthermore, within this specification and the claims, terms including ordinal numbers, such as "first," "second," etc., may be used to distinguish between components. Such ordinal numbers are used to distinguish identical or similar components from one another, and the meaning of the terms should not be limited by such use of ordinal numbers. For example, components combined with such ordinal numbers should not be restricted in terms of their order of use or arrangement by the numbers. If necessary, each ordinal number may be used alternately with the others.

[0027] In this specification, singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as “includes” or “consist of” are intended to specify the presence of features, figures, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood not to preemptively exclude the presence or possibility of adding one or more other features, figures, steps, actions, components, parts, or combinations thereof.

[0028] In embodiments of this disclosure, terms such as “module,” “unit,” and “part” refer to components that perform at least one function or operation, and such components may be implemented in hardware or software, or in a combination of hardware and software. Furthermore, multiple “modules,” “units,” and “parts” may be integrated into at least one module or chip and implemented in at least one processor, unless each needs to be implemented in separate, specific hardware.

[0029] Furthermore, in embodiments of this disclosure, when a part is said to be connected to another part, this includes not only direct connection but also indirect connection through other media. Also, when a part includes a component, it does not exclude other components unless otherwise stated to the contrary, but rather means that it may include other components.

[0030] In the following, various embodiments of the present invention will be specifically described with reference to the attached drawings.

[0031] Figure 1 is a diagram illustrating the schematic structure of a guitar according to one embodiment of the present disclosure and the configuration of a system equipped with a tuner and preamplifier located inside the guitar.

[0032] As shown in Figure 1, a typical guitar is divided into a body, neck, and head. The guitar strings, starting from the body, pass through the saddle, through the neck, and connect to the head, and the sound resonates inside the body through the soundhole formed in the front panel of the body.

[0033] As shown in Figure 1, a tuner 100 and a preamplifier 200 may be provided inside the guitar body, respectively.

[0034] The tuner 100 is an electronic device that provides tuning information based on the frequency of sound vibrations produced by the guitar, and can be installed inside the front panel of the guitar body.

[0035] The Preamp 200 is an electronic device that amplifies the sound produced by the guitar and transmits it to external devices (e.g., amplifiers, speakers, headphones, headsets, etc.), and can be installed inside the front panel of the guitar body.

[0036] In this disclosure, the tuner 100 is connected to the preamplifier 200 and may be powered by the preamplifier 200, and therefore does not need to have its own battery. For example, even if the preamplifier 200 is not directly involved in tuning the guitar, it is connected to the tuner 100 and powered by the preamplifier 200, so the tuning system according to this disclosure can be defined as comprising both the tuner 100 and the preamplifier 200.

[0037] The specific configurations of the tuner 100 and preamplifier 200 will be explained in more detail below with reference to the diagrams.

[0038] Figure 2 is a block diagram illustrating the configurations of the tuner and preamplifier according to various embodiments of this disclosure.

[0039] As shown in Figure 2, the tuner 100 may include at least one of the following: a sensor 110, a display 120, a control unit 130, and a user input unit 140.

[0040] Sensor 110 is configured to detect the frequency of sound vibrations generated by the guitar. It can be implemented using, but is not limited to, a contact vibration sensor, displacement sensor, or acceleration sensor.

[0041] For example, the sensor 110 can identify the frequency of sound by being in close proximity to the front panel of the guitar body and sensing the vibration of the front panel. For instance, if the outer side of one surface of the tuner 100 is in contact with the inner side of the guitar's front panel, the sensor 110 can identify the frequency of the guitar's front panel by contacting the inner side of that surface of the tuner 100. Alternatively, the sensor 110 can be configured to directly contact the guitar's front panel. On the other hand, the sensor 110 can be wired and not included in the body of the tuner 100, and can be mounted outside the tuner 100, for example, attached to at least a portion of the guitar's front panel at a distance from the tuner 100.

[0042] In this case, only the vibrations of the front panel, which directly correspond to the sound of the guitar itself, are precisely measured, and noise such as ambient sounds is not reflected, which has the advantage of potentially guaranteeing tuning accuracy.

[0043] The display 120 is configured to identify the frequency of the sensed sound and provide tuning information, displaying the information visually. The tuning information may include information about the pitch of a sound that matches the sensed frequency, information about the difference between the sensed frequency and the pitch of at least one sound, and so on.

[0044] 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 can include various other conventionally known forms of displays. The display can be implemented as a touchscreen that can sense user touch operations, or as a flexible display that can be folded or bent.

[0045] The control unit 130 is configured to control the overall configuration of the tuner 100. The control unit 130 can be implemented by at least one control circuit or integrated circuit, or it can include at least one processor.

[0046] For example, if the sensor 110 is positioned close to the front panel of the guitar body to detect vibrations of the front panel, the control unit 130 can identify the frequency of the sound based on the frequency of the detected vibrations, generate tuning information, and control the display 120 to display the generated tuning information.

[0047] The user input unit 140 is configured to receive various commands or information from the user. The user input unit 140 can be implemented as at least one button, stick, touchpad, touchscreen, sensor, etc.

[0048] Specifically, the user input unit 140 may be equipped with at least one button for turning the tuner 100 on or off.

[0049] As shown in Figure 2, the preamplifier 200 may include at least one of the following: a microphone 210, a pickup sensor 220, an amplification control unit 230, a user input unit 240, and a display 250.

[0050] Microphone 210 is configured to receive the sound of a guitar and may include at least one circuit for converting the vibrations of sound waves into an electrical signal. Microphone 210 may be built into the body of the preamplifier 200, attached to the body of the preamplifier 200, but formed to protrude externally. Alternatively, microphone 210 may be formed separately from the body of the preamplifier 200, while being connected to the body of the preamplifier 200 by a wire to transmit the audio signal.

[0051] The pickup sensor 220 is a sensor for sensing the sound of a guitar, attached to the saddle or positioned close to the saddle (e.g., indirectly sensing vibrations by sandwiching at least one other plate). Specifically, the pickup sensor 220 may be equipped with a piezoelectric sensor or piezoelectric element, and vibrations of the saddle caused by vibrations of the guitar strings, etc., generate a piezoelectric effect within the pickup sensor 220, which in turn can generate an electrical signal converted from the sound of the guitar.

[0052] If the preamplifier 200 is installed close to the soundhole, the pickup sensor 220 is installed so as to be in contact with the saddle and separated from the main body of the preamplifier 200, so that the pickup sensor 220 and the preamplifier 200 can be connected by a wire. However, if the preamplifier 200 is installed close to the saddle, it is also possible that the pickup sensor 220 is included inside the main body of the preamplifier 200.

[0053] The amplification control unit 230 is configured to amplify the guitar sound and generate an audio signal. The amplification control unit 230 may include at least one electrical circuit, integrated circuit, or processor for amplifying the audio signal.

[0054] Specifically, the amplification control unit 230 can acquire an amplified audio signal via at least one of the audio signals acquired via the microphone 210 and the frequencies sensed via the pickup sensor 220.

[0055] As shown in 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.

[0056] The Blend module 231 is configured to blend a first audio signal acquired via the pickup sensor 220 and a second audio signal acquired via the microphone 210. Specifically, the Blend module 231 can mix the first audio signal and the second audio signal to match a ratio set by user input and generate an amplified audio signal. In this case, the ratio can be set to 100% for only one of them. For example, if the first audio signal is set to 100%, amplification will proceed only with the first audio signal acquired via the pickup sensor 220.

[0057] For example, the Blend module 231 generates an amplified audio signal based on a first audio signal, but blending can be performed by changing the blending ratio of the second audio signal via user input.

[0058] The Clarity module 232 is configured for filtering audio signals. For example, the Clarity module 232 can perform filtering through various settings, such as emphasizing or weakening audio signals of specific frequencies / ranges based on user input.

[0059] The Phase module 233 is configured to change the phase of an audio signal. In this regard, when an audio signal amplified by the preamplifier 200 is output through at least one external device (e.g., a speaker) and input through the microphone 210 of the preamplifier 200, a phenomenon can occur where the phase of the guitar sound and the amplified sound overlap (e.g., feedback). The Phase module 233 can play a role in changing the phase of the audio signal to prevent such a phenomenon.

[0060] The user input unit 240 is configured to acquire various user commands related to the amplification of audio signals. The user input unit 240 can be implemented as at least one button, stick, touchpad, touchscreen, sensor, etc.

[0061] Specifically, the user input unit 240 can acquire user inputs for setting the blending ratio in relation to the functions of the Blend module 231 described above, user inputs for activating the functions of the Clarity module 232, user inputs for activating the functions of the Phase module 233, and user inputs for controlling the volume of the audio signal.

[0062] The display 250 is configured to visually provide various information related to the operation of the preamplifier 200. The display 250 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 include various other conventionally known forms of displays.

[0063] Specifically, the battery status of the preamplifier 200, or the battery status of the battery unit 300 that supplies power to the preamplifier 200, may be displayed via the display 250. The battery status may include the battery charge level, remaining time, etc. On the other hand, instead of the display 250, only a few light-emitting elements may be included as a means of indicating the remaining battery level.

[0064] In addition, the Display 250 can display information regarding the settings of various functions (Blend, Clarity, Phase) (e.g., Blend ratio, Volume), and whether or not the function can be activated.

[0065] Figure 3a is a diagram illustrating the appearance of a tuner according to one embodiment of the present disclosure and the tuning information displayed through the tuner.

[0066] As shown in Figure 3a, the tuner 100 may externally include a power ON / OFF button 140' and a display 120. When powered on, the display 120 may display information regarding the pitch of the sound represented by the guitar's sound. For this purpose, the vibration frequency of the front panel of the guitar's body may be sensed via the sensor 110 of the tuner 100.

[0067] As an example, referring to reference numeral 311 in Figure 3a, the tuner 100 displays the pitch (e.g., A) that is most similar to the currently detected frequency via the display 120. However, if the actual frequency is lower than the pitch, an arrow can be added to the left of the pitch (e.g., A), and the screen can be displayed in white. If the pitch and the actual frequency match exactly, the screen can be displayed in green. If the actual frequency is higher than the pitch, an arrow can be added to the right of the pitch (e.g., A), and the screen can be displayed in white.

[0068] In this way, tuning information is provided via the display 120, allowing the user (performer) to proceed with tuning.

[0069] On the other hand, Figure 3b is a diagram showing the external appearance of a preamplifier according to one embodiment of the present disclosure.

[0070] As shown in 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 activating / 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.

[0071] The preamplifier 200 can be powered by a battery attached to the guitar or by at least one external device. For example, the display 250, attached to the guitar and wired to the preamplifier 200, can display information related to the charge level of the powering battery. Specifically, the display 250 can output light (e.g., an LED) to indicate that the battery charge level is below a certain value. Alternatively, the display 250 can display numerical information about the battery charge level as a percentage. In this case, the battery supplies power to the preamplifier 200, and the preamplifier 200 supplies power to the tuner 100.

[0072] Figure 4a is a diagram illustrating the arrangement and connection relationship of a tuner and a preamplifier, respectively, installed inside a guitar according to one embodiment of the present disclosure. Figure 4a shows the shape of the inner surface of the front panel, which is located inside the body, viewed from the rear towards the front.

[0073] As shown in Figure 4a, the tuner 100 and preamplifier 200 can be mounted on the inside of the front panel of the body so as to match the shape of the soundhole. As a result, when viewing the soundhole from the front of the guitar, the tuner 100 and preamplifier 200 can each be hidden to a certain extent or more.

[0074] As shown in Figure 4a, the preamplifier 200 is wired to the tuner 100 via cable 401 and can supply power to the tuner 100.

[0075] Furthermore, the preamplifier 200 is connected to the pickup sensor 220 via cable 406, allowing it to acquire the audio signal generated through the saddle.

[0076] On the other hand, the preamplifier 200 can also transmit data on the frequency of the sound sensed via the pickup sensor 220 to the tuner 100 via cable 401. In this case, the tuner 100 can display tuning information obtained based on the data (frequency) received from the preamplifier 200 via the display 120. In this case, the tuner 100 can provide tuning information based on the sensing results of the preamplifier 200 even if it does not have or does not use a sensor 110 for sensing the frequency of the sound itself.

[0077] In this regard, in one embodiment, the tuner 100 can periodically deactivate the sensor 110 based on the result of comparing a first frequency sensed via the sensor 110 with a second frequency sensed via the pickup sensor 220 of the preamplifier 200.

[0078] Specifically, while the guitar sound is being detected, the tuner 100 can compare a first frequency detected via the sensor 110 with a second frequency detected via the pickup sensor 220 for a first period of time. During this first period, the tuner 100 can provide tuning information based on the first frequency detected via the sensor 110.

[0079] If the comparison results all match during the first time period, the tuner 100 can deactivate the sensor 110 for the subsequent second time period. In this case, during the second time period, the tuner 100 can provide tuning information by a second frequency sensed via the pickup sensor 220 of the preamplifier 200.

[0080] Then, after the second time period has elapsed, the tuner 100 can again compare the first frequency sensed via the sensor 110 with the second frequency sensed via the pickup sensor 220 during the first time period. Similarly, if all comparison results match, the sensor 110 is deactivated for another second time period, and tuning information may be provided by the second frequency sensed via the pickup sensor 220.

[0081] In this way, accuracy can be ensured by periodically checking whether the frequencies sensed by sensor 110 and pickup sensor 220 match, and if it is confirmed that the frequencies match, not both sensor 110 and pickup sensor 220 are activated, but only the pickup sensor 220 is activated to provide tuning information, so that the same effect in tuning can be provided while reducing power consumption. In particular, in the embodiment of this disclosure in which power is supplied to the tuner 100 from the preamplifier 200, it can be understood that the amount of power used jointly is reduced.

[0082] Furthermore, as a means to ensure a greater reduction in electricity consumption, the first time period described above may be relatively shorter than the second time period.

[0083] On the other hand, if the comparison results described above do not match for at least part of the first time period, the tuner 100 can maintain the activated state of the sensor 110. In this case, even during the second time period following the first time period, the tuner 100 can still provide tuning information using the first frequency sensed via the sensor 110. The tuner 100 can also output warning information via the display 120 indicating that the first frequency sensed via the sensor 110 and the second frequency sensed via the pickup sensor 220 do not match. In this case, the screen may, but is not limited to, be displayed in red. As a result, the user will be able to recognize and take action regarding a problem with at least one frequency sensing function of the tuner 100 and the preamplifier 200.

[0084] On the other hand, as shown in Figure 4a, the tuner 100 and preamplifier 200 can each have one curved surface to fit the circular frame of the soundhole, but when the guitar is viewed from the front, the degree to which the tuner 100 and preamplifier 200 are exposed through the soundhole can be limited.

[0085] In this regard, Figure 4b is a diagram illustrating the shape of a tuner and preamplifier that are formed to fit the shape of a soundhole and are partially exposed according to one embodiment of the present disclosure.

[0086] As shown in Figure 4b, the tuner 100 and the preamplifier 200 each have one exposed surface that is curved, which not only makes them aesthetically pleasing with the soundhole, but also significantly limits the degree to which they are exposed when viewing the guitar from the front.

[0087] Figure 5a shows the shape of a preamplifier installed inside a guitar according to one embodiment of the present disclosure, viewed from below the front through the soundhole.

[0088] As shown in Figure 5a, for the purpose of playing, the preamplifier 200 can be positioned above the soundhole formed in the front panel of the body, based on the guitar being held horizontally. Here, a certain proportion of the preamplifier 200 is hidden so that it is not visible from the front of the guitar through the soundhole, but when viewed from below the front as in Figure 5a, various buttons (e.g., 241, 242, 243, 244, etc.) may be exposed.

[0089] Figure 5b is a diagram illustrating the shape of a tuner provided inside a guitar according to one embodiment of the present disclosure, as viewed from above the front through the soundhole.

[0090] As shown in Figure 5b, based on the guitar being positioned horizontally for performance purposes, the tuner 100 can be positioned below the soundhole formed in the front panel of the body. Here, a certain percentage or more of the tuner 100 is hidden so that it is not visible from the front of the guitar through the soundhole, but when viewed from above the front as in Figure 5b, the display 120 and buttons 140' may be exposed.

[0091] In other words, based on the position where the guitar is held horizontally for the sake of performance, when the performer holding the guitar looks downwards from above into the soundhole (on the front panel), the display 120 of the tuner 100 and other components can be oriented upwards so that they are visible to the performer.

[0092] On the other hand, in one embodiment, the tuner 100 can be powered on or off by user operation of a button 140' provided on the tuner 100. While the tuner 100 is powered on, the tuner 100 can transmit at least one control signal to the preamplifier 200 to deactivate the amplification function of the preamplifier 200. At this time, the control signal may be transmitted via the cable 401 described above, or it may be transmitted via other cables or wireless communication.

[0093] In this way, by deactivating the preamplifier 200 while the tuner 100 is operating, it is possible to prevent situations in which sound amplification and output occur during the tuning process.

[0094] In one embodiment, the tuner 100 can also be designed to automatically shut off after a certain period of time has elapsed since the tuner 100 was powered on. Specifically, the control unit 130 can automatically shut off the power if no vibration or frequency is detected via the sensor 110 for a certain period of time (e.g., 7 minutes).

[0095] Furthermore, in one embodiment, if the tuner 100 is powered on and the preamplifier 200 is deactivated, and the power to the tuner 100 is turned off due to user operation on button 140' or the passage of a certain period of time, the tuner 100 can send at least one control signal to the preamplifier 200 to reactivate the amplification function of the preamplifier 200 just before the power is turned off.

[0096] On the other hand, a system according to one embodiment of the present disclosure may further include a battery unit 300 in addition to the tuner 100 and preamplifier 200.

[0097] In this regard, Figure 6 is a diagram illustrating the schematic structure of a guitar according to one embodiment of the present disclosure and the configuration of a system comprising a tuner, preamplifier, and battery unit provided inside the guitar.

[0098] As shown in Figure 6, a tuner 100, a preamplifier 200, and a battery unit 300 may be provided inside the guitar body.
