Description

A tuner and system installed inside the guitar and exposed only to the player

[0001] The present disclosure relates to a tuner and a system including a tuner for tuning a guitar, and more particularly, to a tuner and a system configured to receive power from a preamplifier.

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

[0003] In the past, tuners for tuning guitars were often unnecessarily exposed in terms of appearance, such as being temporarily fixed to the guitar head or being installed as an integral part of the guitar and attached to one side of the guitar body so that the tuner display was visible from the guitar's exterior.

[0004] In addition, conventional tuners are electronic devices that operate independently and generally require a separate battery just for the tuner, which presents the problem that replacement or maintenance of a separate battery just for the tuner is inevitable.

[0005] The present disclosure provides a tuner that is installed inside a guitar and receives power from a preamplifier, thereby eliminating the need for a separate battery or power supply system.

[0006] The present disclosure provides a tuner that provides tuning information without compromising the appearance of the guitar, such as being installed inside the guitar but having a display visible to the player through the sound hole.

[0007] The present disclosure provides a tuner that is installed inside a guitar and receives power from a preamplifier, thereby eliminating the need for a separate battery or power supply system.

[0008] The present disclosure provides a system that is superior in terms of power consumption without compromising the appearance by configuring a single power supply system through a tuner, preamplifier, and battery section installed inside the guitar.

[0009] The purposes of the present disclosure are not limited to those mentioned above, and other purposes and advantages of the present disclosure that are not mentioned can be understood through the following description and will be more clearly understood through the embodiments of the present disclosure. In addition, it will be readily apparent that the purposes and advantages of the present disclosure can be realized by the means and combinations thereof set forth in the claims.

[0010] A tuning system according to one embodiment of the present disclosure includes a tuner installed on the inside of a front panel of a guitar body and providing tuning information, and a preamplifier installed on the inside of the front panel and amplifying sound generated by the guitar and transmitting the amplified sound to an external device. The tuner is connected to the preamplifier and receives power from the preamplifier.

[0011] The above tuner may include a sensor for detecting vibration of the front panel, and a display for identifying a frequency of sound based on the detected vibration and providing tuning information.

[0012] At this time, the tuner is installed in a direction below the sound hole formed on the front plate of the body based on the horizontal posture of the guitar for the performance, and a certain percentage or more of the tuner can be installed so as to be hidden so as not to be visible through the sound hole from the front direction of the guitar. In addition, the display can face upward so as to be visible to the player holding the guitar when the player looks at the inside of the sound hole from above in a downward direction based on the horizontal posture of the guitar for the performance.

[0013] Meanwhile, the preamplifier may obtain a first audio signal according to the piezoelectric effect of a piezoelectric element included in a pickup sensor when a saddle formed on the front part vibrates based on a sound generated from the guitar, obtain a second audio signal matching the sound generated from the guitar through 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 include a display that provides tuning information, the preamplifier may transmit data on the frequency of sound detected through the pickup sensor to the tuner, and the tuner may display tuning information obtained based on the data through the display.

[0015] Meanwhile, the tuner can be turned on or off according to a user operation of a button provided on the tuner, and while the tuner is turned on, at least one control signal for deactivating an amplification function of the preamplifier can be transmitted to the preamplifier.

[0016] Additionally, the tuner may be automatically turned off after a certain period of time has passed since the tuner was turned on.

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

[0018] A tuning system according to one embodiment of the present disclosure includes a tuner installed on the inside of a front panel of a guitar body and providing tuning information, a preamplifier installed on the inside of the front panel and amplifying sound generated from the guitar and transmitting the sound to an external device, and a battery unit for supplying power to the preamplifier. The tuner is connected to the preamplifier and can receive power from the preamplifier.

[0019] The battery unit may include a power unit comprising a battery box in which at least one battery can be replaced, a connection unit for connecting to the preamplifier and the external device, respectively. In addition, an audio signal output through the preamplifier may be output to the external device through the connection unit.

[0020] The tuner and system according to the present disclosure have the effect of limiting the exposure of the tuner and preamplifier to the outside by being installed adjacent to the sound hole on the inside of the front panel, while still allowing tuning information to be visible to the performer.

[0021] In addition, the tuner according to the present disclosure receives power from a preamplifier, so there is no need for a separate battery, etc., and thus the power supply source of electronic devices attached to the guitar is unified, so there is an advantage in that management is convenient.

Furthermore, unless specifically stated otherwise, the statement that a part includes a certain component does not exclude other components, but rather implies that other components may be included.

[0041] Hereinafter, various embodiments of the present invention will be described in detail using the attached drawings.

[0042] FIG. 1 is a drawing for explaining the schematic structure of a guitar according to one embodiment of the present disclosure and the configuration of a system including a tuner and a preamplifier installed inside the guitar.

[0043] Referring to Figure 1, a typical guitar is divided into a body, neck, and headstock. The guitar strings originate from the body, pass through the saddle, the neck, and the headstock, and sound resonates into the body through a sound hole formed in the front of the body.

[0044] Referring to Fig. 1, a tuner (100) and a preamplifier (200) can be installed inside the body of each guitar.

[0045] A tuner (100) is an electronic device that provides tuning information based on the frequency of sound generated from a guitar, and can be installed on the inside of the front panel of the guitar body.

[0046] A preamplifier (200) is an electronic device that amplifies the sound generated from a guitar and transmits it to an external device (e.g., an amplifier, a speaker, headphones, a headset, etc.), and can also be installed on the inside of the front panel of the guitar body.

[0047] In the present disclosure, the tuner (100) may be connected to a preamplifier (200) and may receive power from the preamplifier (200), and may not have its own battery. Although the preamplifier (200) is not directly involved in tuning the guitar, in that it is connected to the tuner (100) and supplies power to the tuner (100), the tuning system according to the present disclosure may be defined as including both the tuner (100) and the preamplifier (200).

[0048] The specific configuration of the tuner (100) and preamplifier (200) is described in more detail through the drawings below.

[0049] FIG. 2 is a block diagram illustrating the configuration of each of a tuner and a preamplifier according to various embodiments of the present disclosure.

[0050] Referring to FIG. 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).

[0051] The sensor (110) is configured to detect the frequency of sound generated from the guitar. It may be implemented using a contact-type vibration sensor, a displacement sensor, an acceleration sensor, etc., but is not limited thereto.

[0052] For example, the sensor (110) can identify the frequency of the sound by detecting the vibration of the front plate by coming into proximity with the front plate of the guitar body. For example, when the outer side of one side of the tuner (100) is in contact with the inner side of the front plate of the guitar, the sensor (110) can identify the frequency of the front plate of the guitar by making contact with the inner side of the corresponding side of the tuner (100). Alternatively, the sensor (110) may be formed to directly contact the front plate of the guitar. Meanwhile, the sensor (110) may not be included in the main body of the tuner (100) but may be installed on the outside of the tuner (100) by being connected by a wire, and for example, may be attached to at least a portion of the front plate of the guitar while being spaced apart from the tuner (100).

[0053] In this case, only the vibration of the front panel corresponding to the sound of the guitar itself is precisely measured, and noise such as ambient sounds is not reflected, so there is an advantage in that the accuracy of tuning can be guaranteed.

[0054] The display (120) is configured to visually display information by identifying the frequency of the detected sound and providing tuning information. The tuning information may include information about a pitch matching the detected frequency, information about a difference between the detected frequency and at least one pitch, etc.

[0055] The display (120) may be implemented as a liquid crystal display (LCD), a plasma display panel (PDP), an organic light emitting diode (OLED), a transparent OLED (TOLED), a micro LED, etc., but is not limited thereto and may include various other types of displays known in the art. The display may be implemented as a touch screen capable of detecting a user's touch operation, and may also be implemented as a flexible display capable of being folded or bent.

[0056] The control unit (130) is a configuration for controlling the components constituting the tuner (100) as a whole. The control unit (130) may be implemented as at least one control circuit or integrated circuit, or may include at least one processor.

[0057] For example, if the sensor (110) is implemented to detect vibration of the front panel by being close to the front panel of the guitar body, the control unit (130) can identify the frequency of the sound according to the frequency of the detected vibration, generate tuning information, and control the display (120) to display the generated tuning information.

[0058] The user input unit (140) is configured to receive various commands or information from the user. The user input unit may be implemented with at least one button, stick, touch pad, touch screen, sensor, etc.

[0059] Specifically, the user input unit (140) may include at least one button for turning the tuner (100) on or off.

[0060] Referring to FIG. 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).

[0061] The microphone (210) is configured to receive the sound of a guitar and may include at least one circuit for converting the vibration of sound waves into an electrical signal. The microphone (210) may be built into the main body of the preamplifier (200), or may be attached to the main body of the preamplifier (200) but formed to protrude externally. Alternatively, the microphone (210) may be formed separately and spaced apart from the main body of the preamplifier (200) while being connected to the main body of the preamplifier (200) via a wire to transmit an audio signal.

[0062] The pickup sensor (220) is a sensor that is attached to the saddle or installed close to the saddle (e.g., indirectly senses vibrations with at least one other plate therebetween) to detect the sound of the guitar. Specifically, the pickup sensor (220) may include a piezoelectric sensor or a piezoelectric element, and the vibration of the saddle caused by the vibration of the strings of the guitar generates a piezoelectric effect within the pickup sensor (220), and as a result, an electrical signal in which the sound of the guitar is converted may be generated.

[0063] When the preamplifier (200) is installed close to the sound hole, the pickup sensor (220) is installed so as to be in contact with the saddles and is spaced apart 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, when the preamplifier (200) is installed close to the saddles, the pickup sensor (220) may be included within the main body of the preamplifier (200).

[0064] The amplification control unit (230) is configured to amplify the sound of a guitar to generate an audio signal. The amplification control unit (230) may include at least one electric circuit, integrated circuit, or processor for amplifying the audio signal.

[0065] Specifically, the amplification control unit (230) can obtain an amplified audio signal through at least one of an audio signal obtained through a microphone (210) and a frequency detected through a pickup sensor (220).

[0066] Referring to Fig. 2, the amplification control unit (230) can control the Blend module (231), Clarity module (232), Phase module (233), etc. These modules correspond to modules of functional units composed of software and / or hardware.

[0067] The Blend module (231) is configured to perform blending on a first audio signal acquired through a pickup sensor (220) and a second audio signal acquired through a microphone (210). Specifically, the Blend module (231) can generate an amplified audio signal by mixing the first audio signal and the second audio signal according to a ratio set according to a user input. At this time, the ratio may be set to 100% for only one side, and for example, when the first audio signal is set to 100%, amplification is performed only on the first audio signal acquired through the pickup sensor (220).

[0068] For example, the Blend module (231) can perform blending by generating an amplified audio signal based on a first audio signal and changing the blending ratio of a second audio signal according to user input.

[0069] The Clarity module (232) is a configuration for filtering audio signals. For example, the Clarity module (232) can perform filtering according to various settings, such as emphasizing or weakening audio signals of a specific frequency / range, according to user input.

[0070] The phase module (233) is a configuration for changing the phase of an audio signal. In this regard, when an audio signal amplified by a preamplifier (200) is output through at least one external device (e.g., a speaker) and input through a microphone (210) of the preamplifier (200), a phenomenon in which the phases of the guitar sound and the amplified sound overlap (e.g., howling) may occur. The phase module (233) may play a role in changing the phase of an audio signal to prevent this phenomenon.

[0071] The user input unit (240) is configured to obtain various user commands related to the amplification of audio signals. The user input unit may be implemented with at least one button, stick, touch pad, touch screen, sensor, etc.

[0072] Specifically, the user input unit (240) can obtain user input for setting the blending ratio in relation to the function of the Blend module (231) described above, user input for activating the function of the Clarity module (232), user input for activating the function of the Phase module (233), user input for controlling the volume of an audio signal, etc.

[0073] The display (250) is configured to visually provide various information related to the operation of the preamplifier (200). The display (250) may be implemented as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), an OLED (Organic Light Emitting Diodes), a TOLED (Transparent OLED), a Micro LED, etc., but is not limited thereto and may include various types of displays known in the art.

[0074] Specifically, the battery status of the preamplifier (200) or the battery status of the battery unit supplying power to the preamplifier (200) may be displayed through the display (250). The battery status may include the battery's charge level, remaining time, etc. Meanwhile, as a means for indicating the remaining battery capacity, it is also possible to include only a small number of light-emitting elements instead of the display (250).

[0075] In addition, information on the setting values ​​(e.g. Blend ratio, Volume) of various functions (Blend, Clarity, Phase), whether the function is activated, etc. may be displayed through the display (250).

[0076] FIG. 3A is a drawing for explaining the appearance of a tuner and tuning information displayed through the tuner according to one embodiment of the present disclosure.

[0077] Referring to FIG. 3a, the tuner (100) may externally include a button (140') for turning the power ON / OFF and a display (120). When the power is on, the display (120) may display information about the pitch of the guitar's sound according to its frequency. For this purpose, the vibration frequency of the front panel of the guitar's body may be detected through a sensor (110) of the tuner (100).

[0078] For example, referring to the drawing symbol 310 of FIG. 3A, the tuner (100) may display a pitch (e.g., A) most similar to the currently detected frequency through the display (120), and if the actual frequency is lower than the pitch, an arrow may be additionally displayed to the left of the pitch (e.g., A) while displaying the screen in white, and if the pitch and the actual frequency exactly match, the screen may be displayed in green, and if the actual frequency is higher than the pitch, an arrow may be additionally displayed to the right of the pitch (e.g., A) while displaying the screen in white.

[0079] By providing tuning information through the display (120) in this way, the user (performer) can proceed with tuning.

[0080] Meanwhile, FIG. 3b is a drawing showing the appearance of a preamplifier according to an embodiment of the present disclosure.

[0081] Referring to FIG. 3b, the preamplifier (200) may include a microphone (210) on the outside, a rotary switch (241) for setting a blend ratio, a button (242) for activating / deactivating a clarity function, a button (243) for activating / deactivating a phase change function, a rotary switch (244) for setting a volume, and may also include a display (250) for displaying information related to battery charging.

[0082] The preamplifier (200) can be powered by a battery attached to the guitar or at least one external device. For example, a display (250) can be attached to the guitar and connected to the preamplifier (200) by a wire to display information related to the charge of the battery that supplies power. As a specific example, the display (250) can output light (e.g., LED) to indicate that the charge level of the battery is below a certain level. Alternatively, the display (250) can display numerical information about the charge level of the battery as a percentage. In this case, the battery supplies power to the preamplifier (200), and the preamplifier (200) supplies power to the tuner (100).

[0083] FIG. 4a is a drawing for explaining the arrangement and connection relationship of each tuner and preamplifier installed inside a guitar according to one embodiment of the present disclosure. FIG. 4a illustrates the inner side of the front panel corresponding to the inside of the body, viewed from the rear toward the front.

[0084] Referring to Fig. 4a, the tuner (100) and the preamplifier (200) may each be installed on the inside of the front panel of the body to match the shape of the sound hole. As a result, when looking at the sound hole from the front of the guitar, the tuner (100) and the preamplifier (200) may each be hidden by a certain percentage or more.

[0085] Referring to FIG. 4a, the preamplifier (200) can be wired to the tuner (100) via a cable (401) to supply power to the tuner (100).

[0086] Additionally, the preamplifier (200) can be connected to a pickup sensor (220) via a cable (406) to obtain an audio signal generated through the birds.

[0087] Meanwhile, the preamplifier (200) may transmit data on the frequency of sound detected by the pickup sensor to the tuner (100) via the cable (401). In this case, the tuner (100) may display tuning information obtained based on the data (frequency) received from the preamplifier (200) via the display (120). At this time, the tuner (100) may provide tuning information based on the sensing result of the preamplifier (200) without having or using a sensor (110) for detecting the frequency of sound on its own.

[0088] In relation to this, as an example, the tuner (100) may periodically deactivate the sensor (110) based on the comparison result between the first frequency detected through the sensor (110) and the second frequency detected through the pickup sensor (220) of the preamplifier (200).

[0089] Specifically, while the sound of the guitar is being detected, the tuner (100) can compare a first frequency detected through the sensor (110) and a second frequency detected through the pickup sensor (220) for a first period of time. During the first period of time, the tuner (100) can provide tuning information based on the first frequency detected through the sensor (110).

[0090] Here, if the comparison results are all consistent 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 based on the second frequency detected through the pickup sensor (220) of the preamplifier (200).

[0091] Then, when the second time period elapses, the tuner (100) can again compare the first frequency detected through the sensor (110) during the first time period with the second frequency detected through the pickup sensor (220). Similarly, if the comparison results are all the same, the sensor (110) can be deactivated again for the second time period, and tuning information can be provided based on the second frequency detected through the pickup sensor (220).

[0092] In this way, accuracy can be ensured by periodically checking whether the frequencies detected by the sensor (110) and the pickup sensor (220) match, and when the frequencies are confirmed to match, tuning information is provided by activating only the pickup sensor (220) rather than activating both the sensor (110) and the pickup sensor (220), so that the same effect in tuning can be provided while reducing power consumption. In particular, in the embodiment of the present disclosure where the tuner (100) receives power from the preamplifier (200), it can be understood that the amount of power used jointly is reduced.

[0093] Additionally, as a means to secure a greater reduction in power consumption, the first time period described above may be relatively shorter than the second time period.

[0094] Meanwhile, if the above-described comparison results do not match for at least a portion of the first time period, the tuner (100) may maintain the sensor (110) in an activated state. In this case, even during a second time period after the first time period, the tuner (100) may still provide tuning information according to the first frequency detected through the sensor (110). In addition, the tuner (100) may output warning information through the display (120) notifying that the first frequency detected through the sensor (110) and the second frequency detected through the pickup sensor (220) do not match. In this case, the screen may be displayed in red, but is not limited thereto. As a result, the user may recognize that there is a problem with the frequency sensing function of at least one of the tuner (100) and the preamplifier (200) and take action.

[0095] Meanwhile, referring to FIG. 4a, the tuner (100) and the preamplifier (200) may each have one side formed as a curved surface to match the circular border of the sound hole, so that the degree of exposure of the tuner (100) and the preamplifier (200) through the sound hole when the guitar is viewed from the front may be limited.

[0096] In relation to this, FIG. 4b is a drawing for explaining the appearance of a tuner and a preamplifier formed to fit the shape of a sound hole and partially exposed according to one embodiment of the present disclosure.

[0097] Referring to Fig. 4b, the tuner (100) and the preamplifier (200) are each formed with a curved surface on one exposed surface, so that they not only blend well with the sound hole in terms of design, but also the degree of exposure can be significantly limited when looking at the guitar from the front.

[0098] FIG. 5a is a drawing showing a view of a preamplifier installed inside a guitar as viewed from below the front through a sound hole according to one embodiment of the present disclosure.

[0099] Referring to Fig. 5a, the preamplifier (200) may be installed above the sound hole formed on the front panel of the body, based on the horizontal posture of the guitar for the performance. Here, a certain percentage or more of the preamplifier (200) is installed so as to be hidden so as not to be visible through the sound hole from the front of the guitar, but when viewed from below the front as in Fig. 5a, various buttons (e.g., 241, 242, 243, 244, etc.) may be exposed.

[0100] FIG. 5b is a drawing for explaining a view of a tuner installed inside a guitar as viewed from above the front through a sound hole according to one embodiment of the present disclosure.

[0101] Referring to Fig. 5b, the tuner (100) may be installed below the sound hole formed on the front panel of the body, based on the horizontally standing posture of the guitar for the purpose of playing. Here, a certain percentage or more of the tuner (100) is installed so as to be hidden from view through the sound hole from the front of the guitar, but when viewed from above the front as in Fig. 5b, the display (120) and buttons (140') may be exposed.

[0102] That is, when the player holding the guitar looks down from above at the inside of the sound hole (on the front panel) based on the horizontal posture of the guitar for the performance, the display (120) of the tuner (100) can be formed to face upward so that it is visible to the player.

[0103] Meanwhile, as an example, the tuner (100) can be powered on or off according to a user operation of a button (140') provided on the tuner (100). In addition, 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 through the cable (401) described above, or may be transmitted through another cable or wireless communication.

[0104] In this way, by deactivating the preamplifier (200) during the operation of the tuner (100), a situation in which sound amplification and output occur during the tuning process can be prevented.

[0105] Additionally, as an example, the tuner (100) may be designed to automatically turn off after a certain period of time has elapsed since the tuner (100) was turned on. Specifically, the control unit (130) may automatically turn off the power if no vibration or frequency is detected by the sensor (110) for a certain period of time (e.g., 7 minutes).
