Technical Field

[0001] This utility model relates to the field of projection lamp technology, and in particular to a piano-type projection speaker. Background Technology

[0002] Previously, ambient projection lights were typically used in theaters, studios, bars, and nightclubs—scenes requiring stage entertainment effects. However, with the growing demand for home entertainment and creating specific projection atmospheres, portable, compact, low-power, and multifunctional ambient projection lights are increasingly finding their way into people's homes. These ambient projection lights offer a variety of effects, from starry skies to flowing water, from warm and sweet to cheerful and joyful, enriching people's lives.

[0003] However, existing projectors are limited to a single projection function, with fixed and unchanging projection effects. They also lack audio functionality and other entertainment or interactive elements, making them inflexible and unable to meet consumers' higher demands.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 A piano-type projection speaker includes a main body 1, on which a piano module 2, a speaker 3 and a projection module 4 are mounted;

[0032] The main body 1 is equipped with a main control board 5, and the main control board 5 is equipped with a wireless connection module. The piano module 2, speaker 3 and projection module 4 are all electrically connected to the main control board 5.

[0033] The projection module 4 includes a light source 41 and an inner corrugated plate 42 disposed inside the main body 1, and an outer corrugated plate 43 disposed on the surface of the main body 1. The light from the light source 41 can pass through the inner corrugated plate 42 and the outer corrugated plate 43.

[0034] Specifically, the main body 1 is equipped with a piano module 2, which consists of a key matrix composed of white and black keys. When the piano module 2 is in use, pressing the key matrix generates an electrical signal, which is transmitted to the main control board 5. After receiving the electrical signal, the main control board 5 controls the speaker 3 to emit the corresponding note sound. When the piano module 2 is not in use, it can be connected to the wireless connection module (such as Bluetooth connection) set on the main control board 5 through an external electronic device (such as a mobile phone), thereby enabling the speaker 3 to play different music. At the same time, when using the piano module 2 or playing music through the wireless connection, the light source 41 can be turned on, so that the light from the light source 41 shines through the inner corrugated plate 42 and the outer corrugated plate 43, and the texture of the inner corrugated plate 42 and the outer corrugated plate 43 is used to project a water ripple light effect.

[0035] In summary, the technical solution of this utility model, through the setting of piano module 2 and wireless connection module, allows users to actively participate in playing the piano, or to play personalized music through the speaker via wireless connection module, thereby improving interactivity with users. The switchable mode improves flexibility. Furthermore, while playing the piano or playing music, the inner corrugated plate 42 and outer corrugated plate 43 in projection module 4 project water ripple light effects, providing the ability to create scene atmosphere, making it suitable for various scenarios such as leisure, parties, and sleep, and meeting the needs of consumers.

[0036] Please see Figure 1 Based on the above embodiments, it is further proposed that the main body 1 is in the shape of a piano; the setting of the piano shape makes the present invention fit the setting of the piano module 2, thereby improving the overall aesthetics and rationality.

[0037] Please see Figure 2-3 Based on the above embodiments, it is further proposed that the main body 1 is provided with a receiving groove 11, the outer corrugated plate 43 is rotatably disposed on the groove opening of the receiving groove 11, and the inner corrugated plate 42 and the light source 41 are both disposed inside the receiving groove 11.

[0038] A rotary drive source 6 is also installed in the receiving groove 11, and the output shaft of the rotary drive source 6 is connected to the outer corrugated plate 43.

[0039] Specifically, by starting the rotary drive source 6, the output shaft drives the groove of the outer corrugated plate 43 receiving groove 11 to rotate, so that the water ripples projected by the light source are constantly changing, so as to project dynamic ripple light effects, increase the variability of light and shadow, and further enhance the presentation effect.

[0040] Furthermore, by designing the outer corrugated plate 43 in the shape of a record, the record-shaped outer corrugated plate 43 rotates when the speaker 3 plays music, which can create the effect of a record player playing music.

[0041] The rotary drive source 6 is preferably an electric motor, and the light source 41 is preferably an LED lamp bead.

[0042] For preferred options, please refer to [link / reference]. Figure 3-4 On one side of the main control board 5, there are control switches a51 and b52 that are visible through the surface of the main body 1. Control switch a51 is used to control the start and stop of the rotary drive source 6 and the LED beads, while control switch b52 is used to control the connection between the piano module 2, the wireless connection module and the speaker 3. Specifically, the main control board 5 integrates an audio switching circuit, whose input terminals are connected to the piano module 2 and the wireless connection module respectively, and whose output terminal is connected to and drives the speaker 3. The circuit's on / off mode is controlled by control switch b52. In the first mode, the piano module 2 and the speaker 3 are connected. When the piano key matrix is ​​played, the speaker 3 can emit the corresponding sound. In the second mode, the wireless connection module is connected to the speaker 3. When the piano key matrix is ​​played, the speaker 3 does not emit the corresponding sound. However, the speaker 3 can be controlled to play different music by connecting the wireless connection module through an external electronic device.

[0044] The outer corrugated plate 43 is located at the lower end of the piano cover 12.

[0045] Specifically, when in use, lift the piano lid 12 and rotate the support plate 13 so that its bottom is pressed against the protruding edge of the main body 1, thereby forming a triangular support, allowing the piano lid 12 to be opened and fixed. When light passes through the outer corrugated plate 43, it will project the water ripples onto the piano lid 12, forming a visual water ripple effect, avoiding the situation where the space is large and the light is too diffuse, resulting in an unclear light and shadow effect.

[0046] Please see Figure 3 Based on the above embodiments, it is further proposed that a water ripple sticker 44 is also provided at the axis of the outer corrugated plate 43. The outer corrugated plate 43 is fixed to the output shaft of the rotary drive source 6 by setting bolts at the axis. The connecting bolts are covered by attaching the water ripple sticker 44 to the surface of the outer corrugated plate 43, thereby maintaining the aesthetics of the outer corrugated plate 43.

[0047] Please see Figure 2Based on the above embodiments, it is further proposed that the speaker 3 is disposed inside the main body 1, and the lower end of the main body 1 is provided with a sound hole 14 corresponding to the speaker 3; when used, the sound emitted by the speaker 3 is propagated outward.

[0048] Please see Figure 2-3 Based on the above embodiments, it is further proposed that a power supply 7 is provided in the main body 1, which is electrically connected to the main control board 5, and the power supply 7 provides power to each component.

[0049] Please see Figure 3 Based on the above embodiments, it is further proposed that the main control board 5 is also provided with a charging interface 53 that protrudes from the surface of the main body 1.
