In general, the present disclosure provides a system for music visualization, for example used for a loudspeaker system. The present disclosure further provides a loudspeaker system using the music visualization system. The loudspeaker system may include any small portable speaker, home speaker system, etc. The music visualization system may comprise a passive radiator, a plurality of optical lenses and a plurality of light sources. The passive radiator may be movable in a direction of excursion while a music is playing, for example moves up and down. The optical lenses may be operably attached to the passive radiator and may move together with the passive radiator. The light sources may be positioned with respect to the optical lenses so that the light emitted from the light sources can pass through the optical lenses and be projected on an environment surface to form at least one projected area.
By using the passive radiator in combination with the light sources to affect light passing through the lenses, the music visualization system may generate lighting effects to match the beat of a music. The passive radiator moves while music is being played, causing a change in the distance between the lens and the environment surface. The movement of the passive radiator causes light to be projected onto a different area of the environment surface, resulting in a change in the appearance of the light that perfectly matches the beat of the music. With the music visualization system and the loudspeaker system including the music visualization system in the present disclosure, the light being projected is directly linked to and controlled by physical movement of the passive radiator which eliminates any possibility for delay. In addition, the music visualization system in the present disclosure further provides a combination of physical movement of the passive radiator and another light controlling by a control unit, such as light controlling of color, brightness, flickering frequency etc., which additionally increases visualization effect and provides user with a better experience.
The system may further comprise a plurality of optical lenses 102. The optical lenses 102 may be operably attached to the passive radiator 101, and may move together with the passive radiator 101. In some embodiments, the optical lenses 102 may be distributed surrounding the passive radiator. According to implementation, the optical lenses 102 may be specially implemented with optical parameters to adapt the system and may receive lights and project lights. The optical lenses 102 with different parameters or different surface textures may be selected to generating different light patterns. For example, the light beam passing through the lenses may appears wider or narrower causing the project area of the light appears larger or small. For example, the project area of the light may appear different pattern due to the different surface textures of the lenses.
The system may further comprise light sources 103. The light sources 103 may be any light generator or component that can supplement lights. Each of the light sources 103 may be a light emitting diode (LED) light component or a LED array. The LED may be side-firing, up-firing, down-firing, or tilted at any angle. The light sources 103 may be disposed relative to the at least one optical lens so that the light emitted from the light sources can pass through the optical lenses 102. It is understood that
In some embodiments, the light sources 103 may be supported by a board 104, for example a printed circuit board. The light sources 103 may be electrically coupled to the printed circuit board 104. In some embodiments, the light sources 103 may be disposed on the printed circuit board 104 and electrically coupled to the circuit board 104. The circuit board 104 may be operably connected to the passive radiator 101. In some examples, the circuit board 104 is disposed on a surface of passive radiator 101. For example, the circuit board 104 and the passive radiator 101 are glued together with a specific adhesive to ensure that the circuit board 104 will not fall off the passive radiator 101 when the passive radiator vibrates at a high frequency. In some embodiments, the circuit board 104 may not be directly connected the passive radiator 101 and may be fixed in the inner of the loudspeaker box via connection mechanism assuming that the light emitted from the light sources 103 may be supplied to the optical lenses 102.
In some embodiments, the light sources 103 may move together with the passive radiator 101. For example, the light sources 103, the printed circuit board 104 and the optical lenses 102 may all move together with the passive radiator 101. In the illustrated configuration shown in
In some embodiments, the light sources 103 may not move together with the passive radiator 101. For example, the light sources 103 and the printed circuit board 104 are not in any direct or indirect connection with the passive radiator 101. The light sources 103 may be positioned in a relative location to the optical lenses. The positions of the light sources 103 may ensure that at least some of the light emitted from the light sources can pass through at least one optical lens and even in the situation that the optical lenses are moving up and down with the movement of the passive radiator 101. While the passive radiator 101 as well as the optical lenses 102 are moving together as the music is being played, at least some of the light emitted from the light sources 103 pass through the optical lenses 102 and then are projected on different areas on the environment surface 108 due to the change in the distance between the optical lenses 102 and the environment surface 108, resulting in a change in the appearance of the light effect that matches the beat of the beat of the music. For example, the change of projected areas may include a location, size change, etc.
In some embodiments, the system may further comprise a control unit 105 for controlling the light sources 103. For example, the control unit 105 may detect music signals. Along with the rhythm or beat of the music, the control unit 105 controls the light sources 103 to emit light with different color, brightness or flickering frequency, etc.
In some embodiments, the control unit 105 may be coupled to the light sources 103 by one or more connection cables 106. The cable is durable enough to work for the whole life cycle of a product, while not generating any vibration noise. In some embodiments, the control unit 105 may be electrically coupled to and control the light sources 103 via the printed circuit board 104. For example, the control unit 105 may be a processor soldered on the printed circuit board 104. The processor may be any technically feasible hardware unit configured to process data and execute software applications, including without limitation, a central processing unit (CPU), a microcontroller unit (MCU), an application specific integrated circuit (ASIC), a digital signal processor (DSP) chip and so forth.
