Description

A strike module and electron percussion instrument for electron percussion instrument

Technical Field

The present invention relates generally to the field of musical instruments. More particularly, the present invention relates to a striking module for an electronic percussion instrument and an electronic percussion instrument.

Background

Conventional electronic percussion instruments are struck by an external force to generate mechanical vibration in a striking area, and the mechanical vibration is transmitted to a sensing component (e.g., a sensor), thereby causing the sensing component to generate an electrical signal, which is finally processed by a control unit of the electronic percussion instrument to generate sound.

When playing an electronic percussion instrument, it is often necessary to perform hard tapping in order to enhance the playing effect and the hand feeling. For example, when playing an electronic percussion instrument such as a percussion piano, an electronic drum, an electronic gong, or the like, a hammer body is required to strike a striking area such as a key or a drumhead with force, and the striking area transmits the striking force generated by striking to the substrate of the sensing assembly and the sensing unit, respectively. In some scenarios, when the substrate and the sensing unit receive the knocking force, the sensing unit is easily detached from the substrate or damaged. For example, when the piezoelectric ceramic sheet is used as a sensing element, the brittle ceramic is easily detached and broken from the substrate after the substrate and the ceramic receive a striking force, thereby damaging the sensing element and an electronic percussion instrument using the sensing element.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

FIG. 1 is an exemplary block diagram illustrating a tapping module 100 according to an embodiment of the present invention. As shown in fig. 1, the tapping module 100 of the present invention may comprise a tapping area 101 for receiving a tapping action from the outside and a sensing component for generating a corresponding sensing signal in response to the tapping action. The specific form of the striking area 101 may take different forms depending on the electronic percussion instrument, for example, when the electronic percussion instrument is a musical instrument of the piano type, it may take the form of a key; and when the electronic percussion instrument is a drum-like instrument, it may take the form of a drumhead. The sensing arrangement can be flexibly arranged in different positions, for example in the upper, middle or lower part of the striking area 101, based on different requirements, for example different requirements for the striking sensitivity of the striking area 101.

In one embodiment, the sensing assembly may include a substrate 102 and a sensing unit 103. Wherein the substrate 102 may be arranged in correspondence with the tapping zone 101. The substrate 102 may be a conductive body or a circuit board, etc. based on different sensing components.

The sensing unit 103 may be disposed on the substrate 102 and configured to respond to an external tapping motion on the tapping area 101 and obtain a corresponding sensing signal according to a tapping force generated by the tapping motion. The sensing component can be one or more of a piezoelectric ceramic sensor, a vibration sensor, a pressure sensor and a micro-electromechanical system. Taking a piezo-ceramic sensor as an example, the sensing element 103 is made of ceramic, and the substrate 102 may be a ceramic adhesive for adhering the ceramic on the piezo-ceramic sensor. In a preferred embodiment, the ceramic may be a ceramic mixture.

In one embodiment, a glue 104 may be provided at the joint of the substrate 102 and the sensing unit 103 to bond the substrate 102 and the sensing unit 103. The jelly 104 may be disposed in various ways, for example, it may cover all of the sensing unit 103 (i.e. completely cover the surface and the side of the sensing unit 103 far from the substrate 102) and part of the substrate 102 as shown in fig. 1. The part of the substrate 102 refers to a part of an exposed surface of the substrate 102 on a side close to the sensing unit 103, where the exposed surface is a surface of the side not covered by the sensing unit 103. The jelly 104 covers the whole sensing unit 103, so that when the sensing unit 103 is subjected to a knocking force, the jelly 104 can well protect the sensing unit 103, and thus the sensing unit is prevented from being broken and falling off. In addition, the portion of the glue 104 covering the substrate 102 can make the substrate 102 and the sensing unit 103 be firmly bonded and can protect the substrate 102, and meanwhile, the cost of the knocking module 100 can be saved.

In addition, in order to save cost, the glue 104 may cover only a portion of the sensing unit 103 (i.e., a portion of the surface and a portion of the side surface of the sensing unit 103 away from the substrate 102). Alternatively or additionally, the glue 104 may cover the whole of the substrate 102 (i.e. completely cover the exposed surface of the substrate 102 on the side close to the sensing unit 103), so that the substrate 102 and the sensing unit 103 may be bonded more firmly and the substrate 102 may be better protected.

The glue 104 in this embodiment may be one or more of liquid glue, double-sided glue, and sponge glue. Specifically, it may be one or more of 703, 704, 705, 706, 3188, 3M, etc. glue.

It can be understood that the glue 104 can bond the substrate 102 and the sensing unit 103 together, so that the substrate 102 and the sensing unit 103 can resonate (i.e. the vibration frequency and direction are the same) after the sensing assembly is subjected to a knocking force, and thus the substrate 102 and the sensing unit 103 can have the same deformation amount. Therefore, the sensing unit 103 is not easily detached from or damaged by the substrate 102, and the sensing assembly can be protected. Still taking the piezoelectric ceramic sensor as an example, since the glue 104 bonds the substrate 102 and the ceramic to form a resonant body, the ceramic is not easily detached or broken from the substrate 102 when the piezoelectric ceramic sensor is subjected to multiple knocking forces, thereby effectively protecting the piezoelectric ceramic sensor.

The above describes the case where the glue 104 is disposed at the joint of the substrate 102 and the sensing unit 103 of the sensing assembly to realize the resonance between the substrate 102 and the sensing unit 103. It will be appreciated that in order to achieve resonance of the two, a gel may also be provided between the substrate and the striking zone to bond the substrate and the striking zone. A schematic view of a tapping module 200 with a glue arranged between the substrate and the tapping zone 101 is shown in fig. 2.

As can be seen in fig. 2, the jelly 204 may cover only a portion of the substrate 202 (i.e., only a portion of the surface of the substrate 202 near the tapping region 201). This kind of setting mode can its base plate 202 have more vibration space when the response subassembly receives the vibration to can make the response subassembly obtain more accurate sensing signal, and then make electronic percussion instrument can obtain accurate performance signal according to this accurate sensing signal, carry out and can guarantee to play the effect.

The jelly 204 in this embodiment may also be one or more of the liquid glue, the double-sided tape, and the sponge glue. Specifically, it may be one or more of 703, 704, 705, 706, 3188, 3M, and the like.

It can be understood that the glue 204 in the present embodiment can adhere the substrate 202 and the tapping region 201 together, so that the tapping module 200 can generate resonance (i.e. the vibration frequency and direction are the same) after being subjected to the tapping force, in the substrate 202 and the tapping region 201. The resonance can prevent the sensing unit 203 from falling off or being damaged from the substrate 202, thereby protecting the sensing element. For example, in the case of a piezoelectric ceramic sensor, the solution can prevent the ceramic from falling off or chipping from the substrate, thereby effectively protecting the piezoelectric ceramic sensor.

The situation where the gel is provided at different positions of the tapping module to achieve resonance has been described above in connection with several embodiments. It is understood that in order to achieve better resonance, glue may also be provided between the substrate 302 and the sensing element 303 of the sensing assembly and between the substrate 302 and the strike zone 301, as shown in fig. 3. Wherein reference numeral 300 is a knocking module.

The manner of disposing the glue 304 at the joint of the substrate 302 and the sensing unit 303 of the sensing assembly may be the same as or similar to that of the foregoing embodiment (e.g., the embodiment shown in fig. 1). For example, the glue 304 shown in fig. 3 may cover all of the sensing element 303 and part of the substrate 302, and the glue 404 in fig. 4 may cover all of the sensing element 403 and the substrate 402.

Similarly, the manner of disposing the jelly 305 between the substrate 302 and the tap zone 301, etc. may also be the same as or similar to the previous embodiment (such as the embodiment shown in fig. 2). For example, gel 305 in fig. 3 may cover a portion of substrate 302 and gel 405 in fig. 4 may cover a portion of substrate 402. In fig. 4, reference numeral 400 is a tapping module, and reference numeral 401 is a tapping area.

According to the foregoing description of the embodiments, in this embodiment, since the glue is disposed at the joint of the substrate 302 and the sensing unit 303 of the sensing assembly and between the substrate 302 and the striking area 301, the substrate 302, the sensing unit 303, and the striking area 301 may be bonded together to form a resonant body. The resonance body can generate resonance (that is, the vibration frequency and the direction are the same) after being subjected to a knocking force, so that the sensing unit 303 is more difficult to fall off or damage from the substrate 302, and the sensing assembly can be better protected.

Alternatively or additionally, the sensing assembly may further comprise a signal line connected thereto for outputting a sensing signal generated by the sensing assembly. The two signal lines may be respectively connected to the substrate (when the substrate is a conductive body) and the sensing unit, so that the electrical signals on the substrate and the sensing unit can be output to obtain the sensing signal. The signal line may be made of various materials, such as copper wire.

Fig. 5 is a diagram showing an exemplary configuration of an electronic percussion instrument 500 according to an embodiment of the present invention.

As shown in fig. 5, the present invention discloses an electronic percussion instrument 500, and the electronic percussion instrument 500 may include the above-mentioned tapping module. The number of the knocking modules can be set according to needs, and can be 1, 2 or 3, for example. For simplicity of description, fig. 5 is only exemplary of a case including 1 tapping module shown in fig. 3.

As can be seen from fig. 5, the electronic percussion instrument 500 may further include a body 506, and the percussion module may be supported by a support 507 and mounted on the body 506, so that the sensing component in the percussion module is located between the percussion area 501 in the percussion module and the body 506. Specifically, the supporting body 507 may connect the striking zone 501 and the body 506 of the striking module, respectively. In this embodiment, the bottom of the striking module, such as the sensing unit 503 shown in fig. 5, having the gel 504 thereon, is spaced from the body 506 (i.e., there is a gap between the gel 504 and the body 506), thereby facilitating the sensing assembly to generate a sensing signal after receiving a striking force.

The support body 507 may comprise a plurality, for example 2, 3 or 4 support members. The plurality of supporting pieces can be symmetrically arranged by taking the center line of the knocking module (for example, the center line of the knocking area 501) as a symmetric center, so that the knocking module can be stably supported. In addition, a plurality of support pieces can also be evenly arranged at the bottom of the knocking area 501, and the knocking module can be stably supported by the arrangement mode.

To achieve a secure connection of the supports 507, the body 506 and the striking zone 501, each support may be fixedly connected to the body 506 and the striking zone 501, respectively. Specifically, one engaging lug may be provided at each of both ends of each support member, which is riveted or screwed or welded to the body 506 and the striking area 501, respectively, by rivets or screws. In addition to the fixed connection, the supporting member can be detachably connected, for example, clamped, to the body 506 and the striking area 501, so that the striking module can be conveniently detached from the body 506. Alternatively or additionally, the lower end and the upper end of the support member may be inserted into the hole reserved in the body 506 and the striking area 501, respectively, so as to realize the insertion connection of the three.

Further, the supporting body 507 may also include only 1 supporting member, and the supporting member may be exemplified by a ring structure. Based on the stable characteristic of loop configuration itself, can only arrange one this annular support piece in knocking the module below to can simplify support piece's arrangement under the condition of carrying out stable support to the module of knocking. It will be appreciated that the ring support may also be fixedly or removably connected to the body 506 and the striking zone 501 in the manner described above and will not be described in detail herein.

With reference to the foregoing description of the tapping module, those skilled in the art can understand that since the bonding portion between the substrate 502 and the sensing unit 503 and the bonding portion between the substrate 502 and the tapping region 501 of the sensing assembly in this embodiment are provided with a jelly (reference numeral 505 is the jelly disposed between the substrate 502 and the tapping region 501), the substrate 502, the sensing unit 503 and the tapping region 501 can be bonded together to form a resonator. The resonance body can generate resonance after being subjected to knocking force, so that the sensing unit is not easy to fall off or damage the substrate, and the sensing assembly can be better protected.

Fig. 6 is a block diagram showing the composition of an electronic percussion instrument 600 according to an embodiment of the present invention.

As can be seen from fig. 6, the electronic percussion instrument 600 may further include a control unit 602, an output unit 603, and a storage unit 604. The control unit 602 may be configured to receive and process a sensing signal from the sensing component of the tapping module 601; the output unit 603 may be configured to output a sound signal corresponding to the sensing signal according to the processing of the sensing signal by the control unit 602.

As can be seen from the foregoing description of the embodiments, the striking area of the striking module 601 may be a key when the electronic percussion instrument 600 is a piano type instrument, and may be a drumhead when the electronic percussion instrument 600 is a drum type instrument. Taking a musical instrument as an example, the storage unit 604 may be configured to store sound source data associated with keys of the musical instrument. In some application scenarios, the sound source data may comprise data relating to the timbre and/or sound effect of at least one musical organ, for example. According to aspects of the present invention, the at least one organ may include, but is not limited to, one or more of a xylophone, a tremolo and a marimba. Further, the electronic musical instrument of the present invention can exhibit the same performance effect as that of the existing plural percussion instruments according to the difference of the sound source data.

In one embodiment, the storage unit 604 of the present invention may comprise, for example, an IC audio source memory and a data memory. Wherein the IC tone source memory arrangement may be configured to store tone source data associated with an electronic percussion instrument such as a key or drum, including but not limited to data relating to the timbre and/or sound effect of one or more of a xylophone, a tremolo, a marimbap, an electronic drum, a gong, or the like.

In one embodiment, the data storage may be configured to store programs and data related to controlling the operation of the electronic percussion instrument-related modules and units, and may also store other music data related to performance. The data memory may be connected to the control unit 602 via a bus, which may comprise a plurality of sets of memory cells, each of which may be connected to the control unit 602 via a bus.

In one embodiment, the control unit 602 of the present invention may be implemented, for example, using a digital signal processor ("DSP"). The DSP is a microprocessor suitable for performing digital signal processing operations, and is mainly applied to rapidly implement various digital signal processing algorithms in real time. For the present invention, the DSP is used as a control unit, and the audio signal can be processed rapidly in real time. Specifically, firstly, the DSP receives a digital electric signal which is output from the induction component and is subjected to A/D conversion and filtering; secondly, the DSP acquires sound source data associated with the digital electric signal from an IC sound source memory according to the digital electric signal; finally, the DSP sends the sound source data to the output unit so as to output the organ sound signal corresponding to the sound source data.

In one embodiment, the output unit 603 may be configured to output a sound signal corresponding to the sound source data. In one application scenario, the output unit 603 may be a speaker including a power amplifier, so that the sound signal is amplified and played back in the form of sound. In particular, 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 may be configured for impedance matching, which has the advantage of high input impedance and low output impedance, and thus may receive and transmit the current signal of the audio source data with as little data loss as possible. 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 amplifier circuit plays a key role in the power amplifier, the technical index of the final power amplifier circuit determines the technical index of the whole power amplifier, and the final power amplifier circuit can be configured to amplify the current signal sent by the driving amplifier circuit into a high-power signal so as to drive the loudspeaker to play sound.

In one embodiment, the speaker may include a magnet, a frame, a centering pad, a cone, a 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 disposed outside the electronic percussion instrument of the present invention, which may be wirelessly connected with the electronic percussion instrument of the present invention by a wireless communication technique such as bluetooth.

In one embodiment, the electronic percussion instrument 600 of the present invention may further include a control panel (not shown in the figure), which may be connected to the control unit 602 through a line location interface and may be configured to perform function setting on the electronic percussion instrument 600. In one embodiment, the control panel may include, for example, a display screen, a switch button and a volume button of different types of electronic percussion instruments, and other functional modules. The display screen may be configured to display a performance state of the current electronic percussion instrument. The switching keys of different types of electronic percussion instruments can be used for selecting the playing modes of different types of electronic percussion instruments such as xylophone, marimba, tremolo, electronic drum, gong and the like. The volume button may be coupled to a power amplifier, which may be configured to control the size of the music signal.

In one embodiment, the electronic percussion instrument 600 of the present invention may further include a power module (not shown), which may be implemented in various ways to supply power to the electronic percussion instrument 600. For example, but not limited to, the electronic percussion instrument 600 of the present invention may be powered by external mains and a transformer unit disposed inside the power module. The electronic percussion instrument 600 may also be powered by providing a power adapter. In addition, the electronic percussion instrument 600 may be powered by a dry battery by providing a battery box on the body of the electronic percussion instrument 600.
