[0039] The following description will refer to the accompanying drawings to more fully describe the present application. Shown in the drawings are exemplary embodiments of the present application. However, the present application can be implemented in many different forms and should not be interpreted as being limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided to make the present application thorough and complete, and to fully convey the scope of the present application to those skilled in the art. Like reference numerals indicate the same or similar components.

[0040] Reference Figures 1 to 4 , the present application proposes an electronic musical instrument 100, which comprises a main body 110, an induction module 120 and an audio device 130. The induction module 120 is arranged on the surface of the main body 110; the induction module 120 comprises a plurality of induction elements, and the plurality of induction elements are arranged in sequence along a first direction; there is a preset interval between adjacent induction elements; the induction elements are used to output an induction signal when a triggering object is sensed to be close. The audio device 130 is electrically connected with the plurality of induction elements respectively; the audio device 130 is used to output a first preset audio based on the received induction signal; the audio device 130 is also used to output the first preset audio corresponding to each induction signal in sequence based on the receiving sequence when a plurality of induction signals are received.

[0041] In this embodiment, the electronic musical instrument 100 can be a guitar, a violin, a bass, a piano, etc. Taking the electronic musical instrument 100 as a guitar as an example, the guitar includes a head, a neck and a panel. The induction module 120 can be arranged at the neck or the panel of the guitar, and the plurality of induction elements can be arranged in sequence along the width direction of the guitar according to the structure of a traditional guitar. In addition, the arrangement direction of the plurality of induction elements can also be inclined to the width direction according to the habit of playing the guitar. The first preset audio can include a plurality of single-string audios, such as E, B, G, D, A, etc., and can also include a plurality of chord audios. In this way, the user can output the audio of plucking the string by triggering the induction element. The preset interval between adjacent induction elements can be set according to actual application, so as to avoid the user from triggering the adjacent induction element when triggering a single induction element. Among them, the induction element can be arranged to output an induction signal when in contact with a triggering object (such as a human body or other materials that can be inducted), or arranged to output an induction signal when the triggering object is close to a preset range.

[0042] When using the electronic musical instrument 100, the user places a finger close to a certain induction element, triggers the induction element to output an induction signal, and the audio device 130 outputs the corresponding first preset audio according to the induction signal. For example, the user places a finger close to the first induction element, and the audio device 130 outputs the audio of high-pitched E. When the user sweeps the plurality of induction elements with a finger, the audio device 130 receives a plurality of induction signals in sequence and outputs the corresponding first preset audio in sequence. For example, the user sweeps three induction devices in a first direction in sequence, and the audio device 130 outputs the audios of high-pitched E, B and G in sequence, realizing the effect of sweeping the string.

[0043] The present application outputs corresponding induction signals through the plurality of induction elements when triggered by a triggering object, so that the audio device 130 outputs the corresponding first preset audio according to the induction signal. The first preset audio can be set as a single-string audio, a chord audio, etc. according to requirements. In this way, the effect of plucking and sweeping the string can be realized by replacing the string in the traditional stringed instrument, reducing the difficulty of using the electronic musical instrument 100 and facilitating the user to learn and play the instrument.

[0044] In an embodiment, the electronic musical instrument 100 comprises a first sensing element 121, a second sensing element 122, a third sensing element 123, a fourth sensing element 124, a fifth sensing element 125, and a sixth sensing element 126. The first sensing element 121, the second sensing element 122, the third sensing element 123, the fourth sensing element 124, the fifth sensing element 125, and the sixth sensing element 126 are arranged in the first direction in sequence, and the adjacent sensing elements have the preset interval. The first sensing element 121 is configured to output a first sensing signal when a triggering object is sensed to be close; the second sensing element 122 is configured to output a second sensing signal when a triggering object is sensed to be close; the third sensing element 123 is configured to output a third sensing signal when a triggering object is sensed to be close; the fourth sensing element 124 is configured to output a fourth sensing signal when a triggering object is sensed to be close; the fifth sensing element 125 is configured to output a fifth sensing signal when a triggering object is sensed to be close; and the sixth sensing element 126 is configured to output a sixth sensing signal when a triggering object is sensed to be close. The audio device 130 is configured to output a first audio when the first sensing signal is received, output a second audio when the second sensing signal is received, output a third audio when the third sensing signal is received, output a fourth audio when the fourth sensing signal is received, output a fifth audio when the fifth sensing signal is received, and output a sixth audio when the sixth sensing signal is received. The first audio, the second audio, the third audio, the fourth audio, the fifth audio, and the sixth audio are all first preset audios.

[0045] In the embodiment, the six sensing elements can realize the same plucking and chord effect as the six strings in the traditional guitar. For example, the first to sixth sensing elements 126 can be set as high E, B, G, D, A, and low E respectively. The user triggers the six sensing elements respectively to make the audio device 130 output the corresponding single-string audio. When the user performs the sweep and triggers the first to sixth sensing elements 126 in sequence, the audio device 130 outputs the audio of high E, B, G, D, A, and low E in sequence, thereby realizing the sweep audio effect. The user can also perform the sweep and trigger the first to third sensing elements 123 in sequence to make the audio device 130 output the audio of high E, B, and G in sequence, thereby realizing the sweep audio effect. In this way, the plucking and sweep effects of the traditional guitar can be realized, and the pitch problem caused by the structural deformation of the strings and the panel is solved.

[0046] Further, the first to sixth sensing elements 126 can also be set as high notes E, B, G, D, A and low notes E in different musical scales to meet the needs of various playing modes. For example, the electronic musical instrument 100 can include a mode adjustment button, and by triggering the mode adjustment button, the single-string audio corresponding to the first to sixth sensing elements 126 can be set to different musical scales.

[0047] In addition, the number of sensing elements can also be set to different numbers according to actual application, which is not limited herein. For example, when the electronic musical instrument 100 is used as a violin, the number of sensing elements can be set to four.

[0048] In an embodiment, the sensing element includes a capacitive sensor. When a human hand approaches the capacitive sensor, the electric field distribution of the capacitive sensor will change, resulting in a change in the capacitance on the capacitive sensor. The audio device 130 can determine the position of the triggered capacitive sensor by detecting the capacitance change, and then output the corresponding first preset audio. The capacitive sensor can be arranged close to the shell 170 of the electronic musical instrument 100, or arranged on the surface of the shell 170 of the electronic musical instrument 100.

[0049] Reference Figure 5 In an embodiment, the sensing module 120 further includes a signal processing circuit 127. The signal processing circuit 127 includes a plurality of input terminals and a plurality of output terminals; the plurality of input terminals of the signal processing circuit 127 are electrically connected one by one with the plurality of sensing elements, and the plurality of output terminals of the signal processing circuit 127 are respectively electrically connected with the audio device 130. The signal processing circuit 127 is used to detect the sensing signals output by each of the sensing elements, and output corresponding voltage signals based on the sensing signals. The audio device 130 outputs the first preset audio based on the received voltage signals; the audio device 130 is also used to sequentially output the first preset audio corresponding to each of the voltage signals based on the receiving order when receiving a plurality of voltage signals.

[0050] In this embodiment, the signal processing circuit 127 can detect the sensing signals output by the plurality of sensing elements and output corresponding voltage signals. For example, when a human hand approaches the first sensing element 121, the capacitance of the capacitive sensor in the first sensing element 121 changes. The signal processing circuit 127 can detect the capacitance change and output a voltage signal through the first output terminal, so that the audio device 130 outputs the first preset audio according to the voltage signal.

[0051] In an embodiment, the signal processing circuit 127 can include a touch chip. The touch chip can detect the change in capacitance on the sensing element and convert the change in capacitance into a corresponding electrical signal output to the audio device. The touch chip can be implemented by AI03C chip, SSP8011AM chip, PT8042S8 chip, AI32C chip, XW12A chip, XW02C chip, PT8032-S08 chip, etc. In addition, the touch chip can also be implemented by other chips with touch sensing function, which is not limited herein.

[0052] With reference to Figure 1 and Figure 6 In an embodiment, the sensing module 120 further includes a plurality of indicator lights 140, the number of the indicator lights 140 being consistent with the number of the sensing elements. The plurality of indicator lights 140 are electrically connected one by one with a plurality of output terminals of the signal processing circuit 127; and the voltage signal is further used to control the indicator lights 140 to light up.

[0053] In the embodiment, the indicator light 140 can be implemented by an LED light. The plurality of indicator lights 140 can be arranged corresponding to the positions of the plurality of sensing elements. In this way, when the user triggers the sensing element, the audio device 130 outputs the corresponding first preset audio, and the LED light in the area lights up to provide the user with a trigger feedback.

[0054] In an embodiment, the sensing module 120 further includes a circuit board 128. The plurality of sensing elements, the indicator light 140, and the signal processing circuit 127 are all arranged on the circuit board 128.

[0055] In an embodiment, the electronic musical instrument 100 further includes a first trigger assembly 150. The first trigger assembly 150 is used to output a first trigger signal when triggered. The audio device 130 is used to output a corresponding second preset audio based on the received first trigger signal and the sensing signal.

[0056] In the embodiment, the first trigger assembly 150 can be arranged as a pressure sensing trigger, a touch trigger, etc. The user can adjust the scale of the first preset audio by operating the first trigger assembly 150, so that the audio device 130 outputs the second preset audio. In this way, the user can realize single-string audio and sweep-string audio under different scales through the first trigger assembly 150 and the sensing module 120, which enriches the playing mode of the electronic musical instrument 100.

[0057] In an embodiment, the first trigger assembly 150 comprises a plurality of first trigger modules 151; the plurality of first trigger modules 151 are arranged on the surface of the main body 110; each of the first trigger modules 151 is configured to output a corresponding first trigger signal when triggered. The audio device 130 is configured to output a corresponding second preset audio based on the received first trigger signal and the sensing signal.

[0058] In the embodiment, the number of the first trigger modules 151 can be set according to actual needs. For example, when the electronic musical instrument 100 is a guitar, the number of the first trigger modules 151 can be set to seven. The seven first trigger modules 151 can be arranged in the neck area to conform to the usage habit of the guitar. The seven first trigger modules 151 can be set to C scale, D scale, E scale, F scale, G scale, A scale and B scale respectively. In this way, the user can make the audio device 130 output single-string audio and sweep-string audio of different scales by triggering the corresponding first trigger module 151 and the sensing element.

[0059] Reference Figure 7 In an embodiment, the audio device 130 comprises a controller 131 and a loudspeaker 132. The controller 131 is configured to control the loudspeaker 132 to output a first preset audio based on the received sensing signal.

[0060] In the embodiment, the controller 131 can output a corresponding first preset audio signal according to the received sensing signal to control the loudspeaker 132 to output the first preset audio. The user can set the first preset audio output by the audio device 130 when each sensing element is triggered. The controller 131 can be implemented by using a chip with control function such as a microprocessor or a single-chip microcomputer. It can be understood that the controller 131 can output a corresponding first preset audio based on the received sensing signal by using existing software program, which does not belong to the improvement of the method.

[0061] In an embodiment, the electronic musical instrument 100 further comprises a second trigger assembly 160 arranged on the surface of the main body 110. The second trigger assembly 160 is configured to output a corresponding second trigger signal when triggered. The audio device 130 is configured to output a corresponding third preset audio based on the first trigger signal and the second trigger signal.

[0062] In the embodiment, when the first trigger assembly 150 and the second trigger assembly 160 are triggered simultaneously, the third preset audio can be set to a chord audio. In this way, the user can make the audio device 130 output the preset chord audio by operating the first trigger assembly 150 and the second trigger assembly 160, so that the performance of the electronic musical instrument 100 is simpler, which is convenient for beginners to learn and enriches the performance mode.

[0063] In one embodiment, the second triggering component 160 comprises a plurality of second triggering modules. When different second triggering modules and different first triggering modules 151 are triggered at the same time, the preset chord audio output is different, so as to further enrich the playing mode.

[0064] In the foregoing, the specific embodiments of the present application are described with reference to the accompanying drawings. However, it should be understood by those skilled in the art that various changes and replacements can be made to the specific embodiments of the present application without departing from the spirit and scope of the present application.
