Technical Field
[0001] This utility model relates to the field of electronic musical instrument technology, and in particular to a musical note combination sound generation device. Background Technology
[0002] Existing outdoor interactive music devices are mainly divided into two categories: The first category is the percussion-based type, where users directly strike a soundboard or button to instantly produce a single note. Although this type of device is simple to operate, it has significant drawbacks: users passively trigger fixed notes, cannot understand the principles of scale construction, and complex melodies require rapid and continuous striking, which is difficult for beginners to coordinate. The second category is the electronic sheet music type, where users are guided to play by displaying sheet music on a screen. Its disadvantage is that it requires reading the electronic sheet music and operating it simultaneously, which places a heavy cognitive load on children. Based on the above problems, this application develops a note combination sound-producing device suitable for children to play with and improving human-computer interaction. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a sound-generating device for combining musical notes.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a note combination sound-generating device, comprising a housing, wherein the housing is provided with a note switching mechanism, a control module, a sound-generating module, and a switch assembly, wherein the note switching mechanism, the sound-generating module, and the switch assembly are all electrically connected to the control module; the note switching mechanism includes multiple independently arranged scale switches, the operating part of each scale switch being fixedly exposed on the surface of the housing for preset scale parameters of each switch; the switch assembly includes a sliding handle and a trigger unit array, the surface of the housing is provided with a linear movable window for sliding the sliding handle, and the trigger unit array is composed of multiple trigger signal units arranged along the path of the movable window; each trigger signal unit is electrically connected to the control terminal of the scale switch, forming a one-to-one corresponding trigger path; when the sliding handle moves to the target trigger signal unit, the control module drives the sound-generating module to output the scale.
[0005] As a preferred embodiment of this utility model, the plurality of the musical scale switches are arranged linearly along a first direction, and the linear movable window extends along a second direction parallel to the first direction.
[0006] As a preferred technical solution of this utility model, the box body is provided with a guide structure, and the sliding handle forms a sliding fit with the box body through the guide structure; the guide structure is distributed with a plurality of positioning units at intervals along the sliding direction, and the position of each positioning unit corresponds one-to-one with the trigger signal unit; the sliding handle is provided with an elastic positioning component, and when the sliding handle moves to the target trigger signal unit, the elastic positioning component engages and is fixed with the corresponding positioning unit.
[0007] As a preferred technical solution of this utility model, the guide structure is configured as a slide rail, which is fixedly installed on the bottom wall of the box; the positioning unit is a plurality of positioning grooves provided on the upper surface of the slide rail, and each positioning groove is distributed at intervals along the length of the slide rail and corresponds to the position of each trigger signal unit.
[0008] As a preferred embodiment of this utility model, the elastic positioning component includes: a mounting hole located at the bottom of the sliding handle; a spring embedded in the mounting hole; and a steel ball fixedly connected to the lower end of the spring, with a partial protrusion from the lower port of the mounting hole. When the sliding handle moves to the trigger signal unit, the steel ball is engaged in the corresponding positioning groove under the pressure of the spring.
[0009] As a preferred embodiment of this utility model, the bottom of the sliding handle is provided with a U-shaped groove with its opening facing the slide rail; the inner walls on both sides of the U-shaped groove are provided with inward protrusions; the two side walls of the slide rail are provided with anti-derailment cavities along the length direction.
[0010] As a preferred embodiment of this utility model, the trigger signal unit is an infrared sensor head, and multiple infrared sensor heads are arranged at equal intervals along the length of the mounting frame; when the sliding handle moves to the target infrared sensor head, it blocks the light path and generates a trigger signal.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By presetting the scale parameters of each switch through the rotary scale switch, the switch components trigger each scale uniformly. Specifically, the precise locking of the displacement termination position is achieved through the mechanical coupling of the positioning groove of the slide rail and the elastic positioning component (steel ball + spring) of the sliding handle, providing good tactile feedback. When the sliding handle moves to the target trigger signal unit, the control module drives the sound module to output the scale.

Users only need to slide the sliding handle from the starting position to the ending position to play the preset score. In addition, users can also adjust the position of the sliding handle according to the actual situation so that the sound module outputs different scales to form different music, which increases the fun.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] like Figure 1-5 The illustrated musical note combination sound generation device includes a housing 1. The housing 1 contains a musical note switching mechanism 2, a control module, a sound generation module 3, and a switch assembly 4. The musical note switching mechanism 2, the sound generation module 3, and the switch assembly 4 are all electrically connected to the control module. The musical note switching mechanism 2 includes multiple independently configured scale switches 5. The operating part of each scale switch 5 is fixedly exposed on the surface of the housing 1 and used to preset the scale parameters of each switch. The switch assembly 4 includes a sliding handle 6 and a trigger unit array. The surface of the housing 1 has a linear movable window 7 for sliding the sliding handle 6. The trigger unit array consists of multiple trigger signal units 8 arranged along the path of the movable window. Each trigger signal unit 8 is electrically connected to the control terminal of the scale switch 5, forming a one-to-one corresponding trigger path. When the sliding handle 6 moves to the target trigger signal unit 8, the control module drives the sound generation module 3 to output the scale.
[0021] By rotating the scale switch 5 to preset the scale parameters of each switch, the switch assembly 4 triggers each scale uniformly. Specifically, the positioning groove 12 of the slide rail 11 and the elastic positioning assembly 10 (steel ball 15 + spring 14) of the sliding handle 6 achieve precise locking of the displacement termination position, providing good tactile feedback. When the sliding handle 6 moves to the target trigger signal unit 8, the control module drives the sound module 3 to output the scale. Through the two-stage operation of "tuning first, then sliding," the playing difficulty is reduced. Users only need to slide the sliding handle 6 from the starting position to the ending position to play the preset score. In addition, users can also adjust the position of the sliding handle 6 according to the actual situation, so that the sound module 3 outputs different scales to form different songs, increasing the fun. The core improvement of this application does not involve innovation in circuit control logic or hardware itself. The functions of basic signal acquisition and processing, start-stop and speed adjustment of drive elements, and sequential action of actuators are within the conventional design capabilities of those skilled in the art or the application scope of existing mature technologies. Therefore, those skilled in the art, based on the technical solutions disclosed in this application and combined with their knowledge of conventional circuit design, can implement the required control functions without creative effort.
[0022] This application preferably uses a rotary adjustment method for pitch. The scale switch 5 is a commercially available rotary gear switch, such as a rotary encoder. The note switch, control module (using a circuit board), sound module 3, and switch assembly 4 are all commercially available. This application does not involve improvements to the control circuit. How the circuit board switches notes is not the focus of this application. The main purpose of this application is to implement a two-stage operation of "tuning first and then sliding". According to the score, any combination of notes can be preset in advance (notes include seven pitches: do, re, mi, fa, sol, la, si. In this embodiment, the scale switch 5 is provided with seven groups).
[0023] like Figure 1 , 2 As shown, multiple tone switches 5 are arranged linearly along the first direction, and linear movable windows 7 extend along the second direction parallel to the first direction. The layout is reasonable and facilitates the arrangement of electronic components and circuits.
[0024] The box 1 is provided with a guide structure, and the sliding handle 6 forms a sliding engagement with the box 1 through the guide structure; the guide structure is distributed with a number of positioning units 9 at intervals along the sliding direction, and the position of each positioning unit 9 corresponds to the trigger signal unit 8; the sliding handle 6 is provided with an elastic positioning component 10, and when the sliding handle 6 moves to the target trigger signal unit 8, the elastic positioning component 10 is engaged and fixed with the corresponding positioning unit 9.
[0025] The trigger signal unit 8 is an infrared sensor head, and multiple infrared sensors are arranged at equal intervals along the length of the mounting frame 19. When the sliding handle 6 moves to the target infrared sensor head, it blocks the light path and generates a trigger signal. In this embodiment, the sliding handle 6 itself blocks the light path or additional light-shielding components (baffles, blocks, blocking plates, etc.) are provided. The trigger signal unit 8 is an infrared sensor head, and when the sliding handle 6 moves to the target infrared sensor head, it blocks the light path and generates a trigger signal, which is received by the control module and controls the sound-emitting module 3 to emit the corresponding note sound. Alternatively, multiple position sensors are arranged at intervals along the length of the mounting frame 19, and the position sensors are connected to the circuit of the corresponding pitch switch 5. When the sliding switch moves and touches the corresponding position sensor, the corresponding note will be triggered, and the sound-emitting module 3 will emit a sound. The above electronic component connections and control circuits are all existing technologies. This application does not involve improvements in circuit control, so they are not specifically described.
[0026] The guide structure is configured as a slide rail 11, which is fixedly installed on the bottom wall of the box 1; the positioning unit 9 consists of several positioning slots 12 on the upper surface of the slide rail 11 (the number of positioning slots 12 corresponds to the number of trigger signal units 8, or can exceed the number of trigger signal units 8, and can be adjusted adaptively, with the extra positioning slots 12). Each positioning slot 12 is distributed at intervals along the length of the slide rail 11 and corresponds to the position of each trigger signal unit 8.
[0027] The elastic positioning component 10 includes: a mounting hole 13 located at the bottom of the sliding handle 6; a spring 14 embedded in the mounting hole 13; and a steel ball 15 fixedly connected to the lower end of the spring 14 and partially protruding from the lower port of the mounting hole 13. When the sliding handle 6 moves to the trigger signal unit 8, the steel ball 15 is engaged in the corresponding positioning groove 12 under the pressure of the spring 14. In this embodiment, the sliding handle 6 includes a slider 20 that cooperates with the slide rail 11.
[0028] The bottom of the sliding handle 6 is provided with a U-shaped groove 16, the opening of which faces the slide rail 11; the inner walls on both sides of the U-shaped groove 16 are provided with inward protrusions 17; the two side walls of the slide rail 11 are provided with anti-derailment cavities 18 along the length direction.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
