Fig. 1 is a schematic block diagram illustrating an electronic apparatus 100 for processing a performance signal according to an embodiment of the present invention.

As shown in fig. 1, electronic device 100 may include at least one input interface, at least one output interface, and a processor 103. The number of the input interfaces and the output interfaces may be set according to the applicability requirement of the electronic device 100, for example, for an electronic device 100 with a low applicability requirement, it may include only 1 input interface and 1 output interface, and for an electronic device 100 with a high applicability requirement, it may include, for example, 2, 3, or 4 input interfaces, and correspondingly include 2, 3, or 4 output interfaces. For simplicity of description, fig. 1 only exemplarily shows a case including 2 input interfaces (the first input interface 101 and the second input interface 102 shown in the drawing) and 2 output interfaces (the first output interface 104 and the second output interface 105 shown in the drawing).

Based on different application scenarios, for example, different interfaces of connected external devices, the input interface may include a wired transmission interface and/or a wireless transmission interface, and the output interface may also include a wired transmission interface and/or a wireless transmission interface, respectively. The wired transmission Interface may include one or more of a USB ("Universal Serial Bus") Interface, a PCI ("Peripheral Component Interconnect" standard), a PCIE ("Peripheral Component Interconnect express" standard), a LAN ("local area network") Interface, a URAT ("Universal Asynchronous Receiver/Transmitter") Interface, a MIDI ("music Instrument Digital Interface"), a Serial Interface, a parallel Interface, a magnetic-type Interface, a wire bayonet, and a male-female plug, and the Wireless transmission Interface may include one or more of a WIFI ("Wireless Fidelity") Interface, a Bluetooth Interface, and an infrared Interface.

In one embodiment, first input interface 101 and second input interface 102 in fig. 1 may be a serial input interface and a MIDI input interface, respectively, to receive a serial input signal and a MIDI input signal. Accordingly, the first output interface 104 and the second output interface 105 may be a serial output interface and a MIDI output interface, respectively, so as to output a serial output signal and a MIDI output signal.

In another embodiment, the first input interface 101 and the second input interface 102 can also be a PCIE input interface and a Bluetooth input interface, respectively, so as to receive a PCIE input signal and a Bluetooth input signal. Accordingly, the first output interface 104 and the second output interface 105 may be a PCIE output interface and a Bluetooth output interface, respectively, so as to output a PCIE output signal and a Bluetooth output signal.

In one embodiment, the at least one input interface may be configured to connect with an external device separate from the electronic device 100 to receive at least one type of performance signal from the external device. With the electronic apparatus 100 shown in fig. 1, it is possible to receive two types of performance signals through two input interfaces.

The type of the performance signal may be specifically set as needed, and may include one or more of a piano-type performance signal, a drum-type performance signal, a gong-type performance signal, a hi-hat-type performance signal, and a stringed instrument performance signal, for example. The musical instrument playing signals can include playing signals of xylophones, tremolo or marimbas, the drum playing signals can include playing signals of drum sets, tambourines or bass drums, and the gong playing signals can include playing signals of gongs and the like. In addition, the cymbal-like performance signals may include those of a dot-cymbal or a hanging cymbal or the like, and the stringed instrument performance signals may include those of a violin, viola, cello or the like.

The at least one output interface (e.g., the first output interface 104 and the second output interface 105 in fig. 1) may be used to output signals to the outside of the electronic device 100. Based on this, the processor 103 can be electrically connected to the input interface and the output interface, respectively, and is configured to receive the performance signal from the input interface, perform corresponding processing based on the performance signal to obtain an output signal, and finally output the output signal to the outside of the electronic device 100 via the output interface. The processor 103 may be selected from various types of processing devices, and may include one or more of a MCU, a DSP, and a CPU, for example.

Taking the input performance signals as the performance signals of a tremolo and a violin as an example, the processor 103 may process the performance signals of a tremolo and a violin, respectively, so that output signals associated with the tremolo and the violin may be obtained. Therefore, the electronic device 100 of the present embodiment can receive various types of playing signals and obtain corresponding output signals according to the playing signals, so that the applicability is greatly improved compared with the existing electronic device, and thus various playing requirements of users can be met.

For performing a performance via the electronic device, in the embodiment shown in fig. 2, the electronic device 200 may further include a storage module 106, and the storage module 106 may be configured to store at least one sound source data associated with at least one type of performance signal. The sound source data may include data related to timbre and/or sound effect corresponding to at least one type of performance signal, and the electronic device 200 may make corresponding calls according to the performance signal, so that the musical instrument may output a corresponding music signal through the electronic device, and further present a corresponding performance effect.

In one implementation scenario, the storage module 106 may include an IC sound source memory, and the IC sound source memory may store waveform data of a plurality of sound source data included in at least one type of sound source data. When sound source data is stored in the same number of wavelengths, since the wavelength of bass is longer, the data of sound source data corresponding to a lower note number is longer than the data of sound source data corresponding to a higher note number, and therefore the storage space occupied by the data of sound source data in the IC sound source memory is larger.

Based on this, the processor 103 can also be electrically connected to the storage module 106 and used for searching the storage module 106 based on the performance signal to obtain the sound source data corresponding to the performance signal, so that the playing instrument can be conveniently played for performing the corresponding performance.

In order to perform operations such as configuration and/or control of the electronic device so as to meet the corresponding requirements of the user, in the embodiment shown in fig. 3, the electronic device 300 may further include an operation panel 107 and a display module 108. Among them, the operation panel 107 may be electrically connected with the processor 103 and used to input an operation signal to the processor 103 so that the processor 103 outputs a corresponding display signal according to the operation signal. Wherein the operation signals comprise at least configuration and/or control signals of the electronic device 300.

In one implementation, the operation panel 107 may include various keys, such as a switch key for different performance modes and/or a volume key, so that a switch signal and/or a volume adjustment signal for different performance modes may be input to the processor 103. Specifically, when a corresponding type of performance signal is input to the processor 103, the electronic device 300 can be set to a corresponding performance mode by switching the keys so that the processor 103 processes the type of performance signal. The volume key may be configured to control the magnitude of a sound signal emitted by a sound emitting module (described in detail later) to which the electronic device 300 is connected, so as to control the volume of a performance. The operation panel 107 may be connected to the processor 103 by wire or wirelessly, depending on the application scenario.

The display module 108 may be electrically connected to the processor 103 and configured to obtain the display signal from the processor 103 and perform corresponding display according to the display signal. In one implementation scenario, the display module 108 may be configured to display a performance status or a current performance mode, etc. of a currently playing musical instrument, and may include a display device such as a display screen. In order to simplify the structure of the electronic device, the operation panel 107 and the display module 108 may be integrated into a touch display screen.

Fig. 4 is a schematic block diagram showing a musical instrument 400 according to an embodiment of the present invention.

As shown in fig. 4, the musical instrument 400 may include the aforementioned electronic device 401 and at least one performance signal input module, wherein the at least one performance signal input module may be used to transmit at least one type of performance signal to the electronic device 401. The number of performance signal input modules may be specifically set according to the applicability of the musical instrument 400, for example, for a musical instrument 400 with a low applicability requirement, it may include one performance signal input module, and for a musical instrument 400 with a high applicability requirement, it may include, for example, two, three or four performance signal input modules.

For simplicity of description, a musical instrument including two performance signal input modules (the first and second performance signal input modules 402 and 403 shown in the drawing), two input interfaces (the first and second input interfaces 4011 and 4012 shown in the drawing), and two output interfaces (the first and second output interfaces 4014 and 4015 shown in the drawing) is shown in fig. 4 by way of example only. The types of these elements, the connection relationships, and the like may be referred to the description of the foregoing embodiments, and will not be described in detail herein.

As can be seen from fig. 4, the first performance signal input module 402 may be connected to the first input interface 4011 to input one type of performance signals to the processor 4013, and the second performance signal input module 403 may be connected to the second input interface 4012 so that another type of performance signals can be input to the processor 4013. The performance signals input by the first and second performance signal input modules 402 and 403 may be a performance signal of marimba and a performance signal of drum kit, respectively, so that the performance instrument 400 may output an output signal related to marimba and an output signal related to drum kit. In addition, the performance signals input by the first and second performance signal input modules 402 and 403 may also be the performance signals of a tremolo and a gong, respectively, so that the performance instrument 400 can output the output signals related to the tremolo and the output signals related to the gong.

Therefore, the playing musical instrument 400 of the scheme can receive various playing signals and obtain corresponding output signals according to the playing signals, so that the applicability can be greatly improved compared with the existing playing musical instrument, and various playing requirements of users can be further met.

In one embodiment, the performance signal input module may include a plurality of performance elements and a plurality of sensing elements (not shown in the drawings). The playing elements may include keys, strings, or drumheads, etc. depending on the performance, and the number of the playing elements and the sensing elements may be specifically set as desired. For example, when performing a piano-like performance, the musical instrument may include 20 keys and 20 sensing elements; when performing a drum-like performance, the musical instrument may include 2 drumheads and 2 sensing elements, etc.

Each of the plurality of performance elements may be adapted to accept performance motions from the outside. For example, when the playing element is a key, it may be used to receive a tap or a depressing action from the outside; when the playing element is a string, it can be used for receiving the poking action from the outside; and when the playing element is a drumhead, it may be used to receive a striking motion from the outside.

Each of the plurality of sensing elements may be disposed above, below or within a corresponding performance element and is adapted to sense an external performance action on one or more performance elements to generate a performance signal. The sensing elements may include transducers, mems units, sensors, etc., depending on the application. Wherein the transducer can convert the mechanical energy generated by the playing motion into electric energy to obtain a playing signal corresponding to the playing. In addition, the transducer may be selected from one or both of a vibration sensor and a piezoceramic sensor.

The mems unit may respond to the performance motion and generate a corresponding physical response signal, and convert the physical response signal into a performance signal corresponding to the performance. Additionally, the mems unit may be selected from one or more of a mems vibration sensor, a mems gyroscope, a mems acceleration sensor, and a mems pressure sensor.

The sensor can sense the changed capacitance value generated by the trigger area (including the capacitance circuit) corresponding to the sensor based on the triggering action of the performance and convert the capacitance value into a corresponding performance signal. In addition, the sensor may include a Circuit composed of an ASIC ("Application Specific Integrated Circuit") chip or a PSoC ("Programmable System on chip"). It will be appreciated that the capacitance output by the capacitive circuit in the trigger zone can be sensed and detected by a combination of hardware and software.

It is to be understood that the above listed types of sensing elements are merely exemplary and not restrictive, and those skilled in the art may select other types of sensing elements as needed to suit the requirements of different application scenarios.

In order to present the performance effect, in the embodiment shown in fig. 5, the musical instrument 500 may further include a sound generation module 404, and the sound generation module 404 may be configured to output a music signal corresponding to sound source data, where the sound source data may correspond to the performance signal. Specifically, the sound source data may include data relating to timbre and/or sound effect corresponding to at least one type of performance signal as described in the foregoing embodiments. Based on this, when the playing signal is the playing signal of marimba, the sounding module 404 may output a piano tone signal of marimba; when the performance signal is a performance signal of a drum kit, the sound generation module 404 may output a drum sound signal of the drum kit; when the performance signal is a violin performance signal, the sounding module 404 may output a violin tone signal.

In one implementation scenario, the sound generation module 404 may include a speaker of a power amplifier to amplify and play the music signal in the form of sound. The power amplifier may consist of three parts: the power amplifier comprises a preamplifier circuit, a drive amplifier circuit and a final-stage power amplifier circuit. The preamplifier circuit can be configured for impedance matching, which has the advantages of high input impedance and low output impedance, and thus can receive and transmit the current signal of the audio source data with the least data loss. The driving amplifying circuit can be configured to further amplify the current signal sent by the pre-amplifying circuit into a signal with medium power so as to drive the final power amplifying circuit to work normally. The final power amplifying circuit plays a key role in the power amplifier, and the technical index of the final power amplifying circuit determines the technical index of the whole power amplifier. In particular, it may be configured to amplify the current signal sent by the driving amplifying circuit into a high-power signal so as to drive the speaker to play the sound.

In one embodiment, the speaker may include a magnet, a frame, a centering disk, a cone diaphragm, and the like. Alternatively, the speaker may further include the power amplifier described above. A loudspeaker, commonly known as a "horn", is a transducer device that converts an electrical signal into an acoustic signal. Specifically, the audio power signal causes the cone or diaphragm of the speaker to vibrate and resonate (resonate) with the surrounding air to generate sound through electromagnetic, piezoelectric, or electrostatic effects. Alternatively, the speaker may be an external component that is connected to the processor via a wired connection (e.g., USB connection) or a wireless connection (e.g., bluetooth connection).

Based on this, the processor 4013 can also be electrically connected to the sound generation module 404 and configured to control the sound generation module 404 to output a music signal corresponding to the sound source data. Specifically, the processor 4013 may call the sound source data from the storage module to which the processor 4013 is connected in the manner described in the foregoing embodiment, so as to control the sound generation module 404 to output a music signal corresponding to the sound source data.
