Description

Technical Field

[0001] This utility model relates to the field of electric piano technology, and in particular to a single-cavity structure for an electric piano. Background Technology

[0002] Currently, most digital pianos use a dual-speaker structure, which is installed on the same bottom surface of the middle plate. When the piano is working, the dual-speaker structure uses a mixed sound production method, which produces noise and a muddy tone. The dual-speaker structure also has a certain delay. In order to solve the above technical problems, a new sound cavity structure needs to be designed. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a unique sound chamber structure for an electric piano, which has the characteristics of effectively increasing volume, improving sound quality, and making the sound of the electric piano more mellow and pleasant.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a single-cavity structure for an electric piano is provided, including a top cover, an upper baffle, and three corners. The upper baffle is installed below the rear part of the lower end face of the top cover. Several three corners are installed between the upper baffle and the top cover. A gap is left between the top cover and the upper baffle. Semi-open cavities are installed at both ends of the lower end face of the top cover. An opening is provided at the rear end of the semi-open cavities. The opening of the semi-open cavities abuts against the upper baffle. A speaker is installed inside the semi-open cavities.

[0005] In this technical solution, a top cover and an upper baffle are used as the mounting base for a semi-open sound cavity. Three corners are provided to facilitate the installation of the top cover and upper baffle. Gaps are provided to facilitate sound transmission. The two semi-open sound cavities allow two independent sound cavities to be formed at the lower end of the top cover.

[0006] The speaker emits electronic sounds that form sound waves that enter the two cavities. These sound waves travel through the air inside the cavities, creating resonance. The walls of the semi-open sound cavities block the propagation path of the sound waves. When the sound waves hit the walls inside the cavities, some of them pass through the walls into the air, while others bounce back into the air inside the cavities, creating an echo that makes the sound of the electric piano richer and more melodious.

[0007] This technical solution creates two independent sound cavities. When the speaker emits sound, the sound waves circulate within the cavity without interfering with each other. The sound cavities are installed at the front of the top cover, resulting in frontal sound output, making the sound more direct and eliminating delay.

[0008] As a supplement to this technical solution, a sound-permeable cloth is pasted in the gap to prevent dust from entering.

[0009] As a supplement to this technical solution, adhesive clothing is bonded between the top cover, the upper baffle and the semi-open sound cavity.

[0010] As a supplement to this technical solution, the three-sided corner includes an inclined bracket and a support bracket. The inclined bracket is provided with support brackets extending to both sides at both ends. The support brackets and the lower end face of the top cover or the front end face of the upper baffle form a close fit.

[0011] As a supplement to this technical solution, the upper outer side of the semi-open acoustic cavity is provided with several docking ears, which are connected to the top cover by screws.

[0012] This technical solution installs the speaker inside a cavity. When the speaker emits sound waves, the cavity resonates, effectively increasing the volume and improving the sound quality. The sound waves also create an echo, making the sound of the electric piano richer and more pleasing. It provides some low-frequency enhancement, avoiding delay or resonance distortion. The sound outlet design releases standing wave energy within the enclosure, reducing resonance interference in the mid-to-high frequency range and resulting in a purer tone. It is easy to adjust and install, has wide applicability, and is suitable for various music genres (vocals, jazz, chamber music, etc.).

[0013] Beneficial effects: This utility model relates to a single-cavity structure for an electric piano. It uses a top cover and an upper baffle as the mounting base for a semi-open cavity. It also uses three corners to facilitate the installation of the top cover and upper baffle. It uses gaps to facilitate sound transmission. Furthermore, the two semi-open cavities form two independent cavities at the lower end of the top cover. This effectively increases the volume and improves the sound quality, making the sound of the electric piano more mellow and pleasant. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] The embodiments of this utility model relate to a single-cavity structure for an electric piano, such as... Figure 1 As shown in Figure 3, the device includes a top cover 1, an upper baffle 2, and three-sided corner brackets 3. The upper baffle 2 is installed below the rear part of the lower end face of the top cover 1. Several three-sided corner brackets 3 are installed between the upper baffle 2 and the top cover 1. A gap 6 is left between the top cover 1 and the upper baffle 2. Semi-open acoustic chambers 4 are installed at both ends of the lower end face of the top cover 1. An opening is provided at the rear end of the semi-open acoustic chamber 4. The opening of the semi-open acoustic chamber 4 abuts against the upper baffle 2. A speaker 5 is installed inside the semi-open acoustic chamber 4.

[0020] In this technical solution, a top cover 1 and an upper baffle 2 are set as the mounting base for a semi-open sound cavity 4. At the same time, a three-sided corner 3 is set to facilitate the installation of the top cover 1 and the upper baffle 2. A gap 6 is set to facilitate sound transmission. Meanwhile, the two semi-open sound cavities 4 make the lower end of the top cover 1 form two independent sound cavities.

[0021] The speaker emits electronic sounds that form sound waves that enter the two cavities. These sound waves travel through the air inside the cavities, creating resonance. The walls of the semi-open sound cavity 4 block the propagation path of the sound waves. When the sound waves hit the walls inside the cavity, some of them pass through the cavity walls into the air, while others are reflected back into the air inside the cavity, causing the sound waves to revolve within the cavity and create an echo. This makes the sound produced by the electric piano richer and more melodious.

[0022] This technical solution creates two independent sound cavities. When the speaker emits sound, the sound waves circulate within the cavity without interfering with each other. The sound cavities are installed at the front of the top cover, resulting in frontal sound output, making the sound more direct and eliminating delay.

[0023] As a supplement to this technical solution, sound-permeable cloth is pasted at the gap 6 to prevent dust from entering.

[0024] As a supplement to this technical solution, adhesive clothing is bonded between the top cover 1, the upper baffle 2 and the semi-open sound cavity 4.

[0025] As a supplement to this technical solution, the three-sided corner 3 includes an inclined support 7 and a bracket 8. The inclined support 7 is provided with brackets 8 extending to both sides at both ends. The brackets 8 and the lower end face of the top cover 1 or the front end face of the upper baffle 2 form a close fit.

[0026] As a supplement to this technical solution, the upper outer side of the semi-open acoustic cavity 4 is provided with several docking ears, which are connected to the top cover 1 by screws.

[0027] Example

[0028] Two independent semi-open sound chambers 4 and a speaker 5 are provided, and self-adhesive clothing is pasted on the contact surfaces of the semi-open sound chambers 4 with the upper baffle 2 and the top cover 1. The upper baffle 2 and the top cover 1 are assembled with three corner brackets 3 according to process requirements.

[0029] There is an 8mm gap 6 between the top cover 1 and the upper baffle 2. This gap 6 is the sound outlet. A sound-permeable cloth is pasted at the gap 6 to prevent dust from entering the cavity.

[0030] Two independent sound cavities are formed. When the speaker 5 emits sound, the sound waves circulate within the cavity without interfering with each other. The sound cavities are installed at the front of the top cover 1, making the sound more direct and without delay.

[0031] When playing the electric piano, the on / off switch is turned on to form an electrical pulse. When the key is pressed, the pulse generates a waveform of a certain frequency, which is sent to the speaker 5 through the frequency crossover.
