[0044] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, this application embodiment provides a stringed instrument 1, including a body 109 and an electronic control system 100. The electronic control system 100 is connected to the body 109 and is used to acquire vibration signals of the stringed instrument 1 and convert the vibration signals into electrical signals.

[0046] like Figure 2 As shown, the electronic control system 100 includes a core processing module 10, a first circuit module 11, a second circuit module 12, a string instrument end input / output module 13, a user end input / output module 14, and a power supply module 15.

[0047] The core processing module 10 includes at least one first processor 101, which is used to support the operation of the operating system of the string instrument 1.

[0048] The first circuit module 11 includes at least one second processor 111, which is used to process audio data. The first circuit module 11 is electrically connected to the core processing module 10.

[0049] The second circuit module 12 includes at least a comparator 121 and a coprocessor 123.

[0050] The string instrument input / output module 13 is used to acquire the vibration of the string instrument 1 and generate audio data. The string instrument input / output module 13 is electrically connected to the core processing module 10 through a coprocessor 123. The coprocessor 123 receives the audio data acquired by the string instrument input / output module 13 and records the time during which the string instrument 1 is in a vibrating state. The time during which the string instrument is in a vibrating state can refer to the time during which the instrument body vibrates. The coprocessor 123 is further used to wake up the core processing module 10 or the first circuit module 11 when the string instrument 1 is in a standby state and the power supply to the second processor 111 is off.

[0051] Furthermore, the electronic control system 100 includes a parallel first circuit module 11 and a second circuit module 12. On one hand, an independent coprocessor 123 assists in recording the occurrence and duration of vibrations to record the usage time and patterns of the stringed instrument 1. On the other hand, the coprocessor 123 in the second circuit module 12 wakes up either the core processing module 10 or the first circuit module 11. By using a parallel circuit with low overall power consumption to wake up the core processing module 10 in standby mode, and thus wake up the electronic control system 100, the power consumption of the stringed instrument 1 in standby mode is reduced, extending the instrument's runtime.

[0052] The core processing module 10 can be used to run an operating system, which can be a common operating system, such as Android; the first processor 101 can be a central processing unit that supports the operating system.

[0053] In one embodiment, the first processor 101 may be a microcontroller or an ARM (Advanced RISC Machines) processor, an X86 (The X86 architecture) processor, a MIPS (Million Instructions Per Second) processor, a POWER processor, etc.

[0054] The first circuit module 11 also includes an operational amplifier circuit 112 and a codec 113. The string instrument end input / output module 13 is electrically connected to the core processing module 10 via the operational amplifier circuit 112, the codec 113, and the second processor 111.

[0055] In one embodiment, the second processor 111 may be a DSP (Digital Signal Processing) audio processor. The codec 113 may be a device or program capable of transforming a signal or a data stream, wherein the transformation includes both the operation of encoding or extracting the signal or data stream to obtain a coded stream, and the operation of recovering a form suitable for observation or operation from the coded stream for observation or processing.

[0056] The second circuit module 12 also includes an amplifier 122. The string instrument end input / output module 13 is electrically connected to the core processing module 10 via the amplifier 122, the comparator 121 and the coprocessor 123 in sequence.

[0057] In one embodiment, comparator 121 can compare two or more data items to determine whether they are equal, or to determine their magnitude relationship and order of arrangement; amplifier 122 can be a combination of electronic components or devices that can amplify the voltage or power of the input signal.

[0058] In one embodiment, the electronic control system 100 further includes a timing module 124 (RTC), which is electrically connected to the coprocessor 123 to assist the coprocessor 123 in performing continuous or intermittent time recording.

[0059] In one embodiment, the coprocessor 123 is used to transmit the time recorded by the timing module 124 to the first processor 101 after the string instrument 1 changes from a sleep state to a wake-up state, and the operating system records and provides feedback.

[0060] The stringed instrument 1 of this application has the ability to sense, awaken and record vibrations (including playing), and can realize the statistics of playing time.

[0061] In one embodiment, when the string instrument 1 is in deep sleep, the mobile control software (APP) corresponding to the string instrument 1 or the operation software on the string instrument 1 is not opened. At this time, time statistics can be performed by the coprocessor 123, and the statistics process does not require waking up the operating system.

[0062] In one embodiment, the mobile control software (APP) corresponding to the string instrument 1 is opened. At this time, the system of the string instrument 1 is allowed to be in a deep sleep state or not in a deep sleep state, and the coprocessor 123 can perform playing time statistics.

[0063] In one embodiment, the stringed instrument 1 is in a screen-off state, and the coprocessor 123 can perform playing time statistics.

[0064] In one embodiment, the string instrument 1 is playing accompaniment, the metronome is working, the recording unit is working, or it is in video playback mode. At this time, even if the string instrument 1 is not played, the coprocessor 123 can still perform time statistics.

[0065] In one embodiment, when the stringed instrument 1 is played intermittently, the coprocessor 123 can also perform playing time statistics.

[0066] In one embodiment, when the operating system (which may be an Android system) of the string instrument 1 is in an upgrade state, the coprocessor 123 can also perform playing time statistics.

[0067] In one embodiment, when the stringed instrument 1 is in the off state, the coprocessor 123 can also perform playing time statistics.

[0068] In one embodiment, the standby power consumption of comparator 121 is lower than that of the standby power consumption of the second processor 111.

[0069] Furthermore, a coprocessor 123 with lower power consumption and audio signal recognition capability (or vibration discrimination capability) is selected to replace the DSP audio processor as the working unit of the module that wakes up the core processing module 10, or the string instrument 1 can record the playing time without waking up the core processing module 10 (including the operating system), so as to improve the battery life and time recording function of the string instrument 1.

[0070] The string instrument input / output module 13 is electrically connected to the user input / output module 14 through the core processing module 10 and realizes electrical signal interaction.

[0071] In one embodiment, the string instrument input / output module 13 can be used to detect, collect, and transmit the vibrations of the string instrument 1; furthermore, the string instrument input / output module may include hardware units such as a microphone, a pickup bar, and an audio output port.

[0072] In one embodiment, the user-end input / output module 14 can be used to realize the interaction between the stringed instrument 1 and the user, allowing the user to issue commands to the electronic control system 100 through the user-end input / output module 14, and to receive feedback information from the electronic control system 100 through the user-end input / output module 14. The user-end input / output module 14 may include a touch display unit, a memory, a storage device, a wireless communication module, etc.; wherein, the memory can be the system's running memory, the storage device can be used for system and data storage, and the wireless connection module may include a WIFI module or a Bluetooth module. The WIFI module can be used to connect to a network or establish a network hotspot to communicate with other devices, and the Bluetooth module can be used to transmit audio information to other Bluetooth devices.

[0073] The power supply module 15 is electrically connected to the core processing module 10 to supply and store electrical energy to the electronic control system 100.

[0074] In this embodiment, as Figure 1 As shown, the string instrument 1 can be an instrument similar to a guitar (classical guitar, electric guitar, ukulele), etc. In other embodiments, the string instrument 1 can also be other stringed instruments with resonating cavities such as erhu, banhu, zhonghu, gaohu, pipa, guzheng, banqin, violin, viola, cello, etc.

[0075] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
