The present disclosure generally relates to speakers, and more particularly, to outdoor loudspeakers.
Loudspeakers are used in audio systems for the reproduction of sound. In some applications, the speakers may be used outdoors. As the loudspeakers are used outdoors, elements can be a problem. Moisture, e.g., rain, can ruin a loudspeaker. In some cases, direct sunlight, e.g., in the southwest United States, can ruin some components in a loudspeaker.
In at least one embodiment, a loudspeaker is weather resistant and includes environmental lighting.
An outdoor loudspeaker system can include a plurality of outdoor loudspeakers with at least some of the loudspeakers including a lamp and at least one audio driver. A lighting controller is in communication with a lamp or multiple lamps and may output lighting signals to the lamps in the plurality of outdoor loudspeakers. An audio controller is in communication with the audio driver(s) and can output audio signals to the audio drivers of the plurality of outdoor loudspeakers. In an example, a lighting conduit houses lighting wiring from the lighting controller to the plurality of outdoor loudspeakers. In an example, an audio conduit houses audio wiring from the audio controller to the plurality of outdoor loudspeakers, the audio conduit being separate from the lighting conduit.
In an example embodiment, the outdoor loudspeaker of the plurality of outdoor loudspeakers includes a base to contact ground, a top on the base and a cap on the top, and wherein the lamp is mounted beneath the cap and outside the top.

In an example, embodiment, the lamp includes circuitry to receive signals to control at least one of or both the quantity of light and the color of light emitted therefrom.
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
A cap 103 is fixed to the top portion 102 remote from the base 101. The cap 103 can be a dome with a rounded top and a dimension, e.g., a diameter, greater than a dimension of the top portion 102 and greater than a dimension of the base 101. The cap 103 can be positioned on the top of the top portion 102. The cap 103 can be dimensioned and shaped to shield, at least partially, the top 102 and base 101 from the environment, e.g., rain and sun. The cap 103 can have a dome shape with a continuous body. The cap 103 includes a brim 104 that extends outwardly past the walls of the top 102. A raceway can be positioned in the brim whereat a lamp can be fixed. The raceway is positioned outside the top 102. The raceway can extend around the entirety of the brim. In an example, embodiment the raceway extends about halfway around the brim. The raceway may extend only around the front of the outdoor loudspeaker and the sides, i.e., the rear of the loudspeaker does not have a raceway or a lamp. The raceway can act as a light guide to transmit light throughout the brim and outwardly from the raceway.
The lamp 110 is positioned in the cap brim so that light is emitted into the surrounding environment outside the outer walls of the top 102. The lamp 110 may include at least one or a plurality of light sources. The light sources may be covered by a lens that diffuses the light and protects the light source from the environmental elements. In an example, the light source includes a plurality of solid state light sources, e.g., light emitting diodes (LEDs). The plurality of solid state light sources is positioned in the brim 104 with the emitting side thereof outside the top portion 102. In an example, the light sources are equally spaced around the brim 104. The cap 103 directs the light from the lamp or the light source downwardly and outwardly. The cap 103, in some embodiments, blocks the light from being emitted upwardly or directly laterally from the cap. In an example, the light sources are positioned to be aligned with the speakers 107-109. In an example, there are at least four light sources, six light sources, at least ten light sources, at least twelve light sources or more. The light sources can be spread spectrum, e.g., white, light sources. In an example, the light sources are color light sources. The color of the light sources can be controlled by circuitry within the loudspeaker 100. That is, the light sources emit a narrower band light wavelengths to tune emission to a specific color. In an example, the change in the color of the lights can be controlled by the frequencies in the music being played by the speaker assembly 105. The light may additionally be controlled to change color of flashing patterns based on preloaded lighting instructions or circuitry. In an example, the lamp 110 is separate from the audio, e.g., the wiring, circuitry and speakers. Thus, the lamp 110 is controlled by different circuitry than the audio. The power supply to the lamp is transmitted on a different circuit than the audio signal circuitry.
The lamp 110 may be part of a series of lamps that are connected to lighting circuitry to power the lamps. The lighting circuitry can power the lamps and provide an on/off signal. The lighting circuitry is separate from the audio circuitry. The lighting circuitry can provide a constant power signal, e.g., a DC voltage. The power signal can be 3 volts, 5 volts, or 12 volts.
In an example, additional lighting devices may be positioned on the top 102. Such additional lighting devices can be below the speaker assembly 105 or on the back of the top 102. The additional lighting may extend around the speakers 107-109. The additional lighting can be controlled by the lighting circuitry, separate from the audio circuitry.
The speaker assembly 105 may include at least one driver, which converts electrical signals into audio signals broadcast from a driver of a speaker assembly 105 to be transmitted through the air. In an example, the speaker assembly 105 includes a first audio driver 107, a second audio driver 108 and a third audio driver 109. At least one of these drivers 107-109 has a different frequency response than at least one of the other drivers. The drivers 107-109 are for outdoor use with some weather resistance. In an example, the drivers 107, 109 are for low and mid-range frequencies of the audio signal. The driver 108 is for high range frequencies of the audio signal. The speaker assembly 105 includes circuitry to receive an input signal appropriately forward a frequency of the input signal to the appropriate driver 107, 108, or 109. The circuitry may also power the driver.
Optionally, the speaker assembly 105 can be covered with a grill, semi-rigid cover or other ornamental structure attached to the top 102. Such a covering may physically protect the speaker assembly 105.
In an example, the audio signal to the speaker 100 is provided by a different circuit than the signal powering and controlling the lamps 110. The supplies of the audio signal may be in a separate conduit from the wiring of the lighting system.
A first wire 208 is connected to the speaker 107A. A second wire 209 is connected to the lamps 110A. The first wire 208 is separate from the second wire 209. A sound controller is connected to the first wire 208. A lighting controller is connected to the second wire 209. The first wire 208, where it extends outside the outdoor speaker 100A, may be housed in a first conduit underground to connect the outdoor speaker 100A to an audio circuitry. The second wire 209, where it extends outside the outdoor speaker 100A, may be housed in a second conduit underground to connect the outdoor speaker 100A to lighting circuitry. The outdoor speaker 100A may include a spike 801 to secure the outdoor speaker 100A in the ground 114. The spike 801 extends from the bottom of the top housing 102A downwardly to reach further into the ground.
The cap 303 prevents rain and other moisture from entering the hollow sound pipe 302, while allowing sound to exit the above ground end of the sound pipe 302 distal to the chamber 301. The bottom of the cap 303 adjacent the sound pipe 302 and inwardly of outer raceway. The lighting device 310, e.g., a lamp, is fixed in the cap 303, e.g., in a raceway, which can be arcuate or circular around the periphery cap 303 radially outwardly sound pipe. In an example, the lighting device 310 is positioned at the periphery of the cap 303. The lighting device 310 may include the features of the lighting devices described herein.
The lighting controller 540 may send power and control signals, e.g., over wires or wirelessly, to the outdoor loudspeakers to control the lamps and the light emitted from the lamps. The lamps include circuitry to receive the control signals and use the control signals to control the light emitted from the lamps. The lighting controller 540 can send a color control signal to select or change the color of the light emitted from the lamps. The lighting controller 540 can send brightness control signal to select the quantity of light, e.g., change the emitted lumens, or dim the light from the lamps.
The outdoor lighting system may include the lighting controller 540 and the lamps 110, 110A, 310 at the outdoor speakers. The controller 540 may automatically sense, convey, control and recording data relevant to the operation of the lighting system and each of the lamps controlled. At each of plural light locations in the network of lamps, there is a controller circuit that receives electric power input and control signals. The lighting system's power lines form portions of a bi-directional data link via which data is transmitted from each controller circuit to the lighting controller.
The loudspeakers may be mounted in an exterior wall, mounted to an exterior structure, such as a deck, a walkway, a pier, a dock, a fixed in the ground, or other outdoor structures. In at least one embodiment, the loudspeaker is a woofer, or subwoofer. The term woofer may mean either a subwoofer or a traditional woofer. Subwoofers and traditional woofers operate in a low frequency range, e.g., the bass range. In general, the bass range is a low frequency range, which may be around 20 Hertz (Hz) to 400 Hz. In the bass range, subwoofers generally emit sound between 20 Hz and 200 Hz, and traditional woofers generally emit sound between 40 Hz and 400 Hz. As used herein, the woofer could be a subwoofer or a traditional woofer.
The above described embodiments of the loudspeakers have a generally round shape where the lights are located, in will be understood that other shapes are within the scope of the present invention. The light supporting structures may have a polygon shape, a partly polygon shape, ovoid, or partly ovoid shape.
Many of the above described embodiments show a loudspeaker that is mounted in the ground. Other mounts may be within the scope of the present invention. In an example, the loudspeaker may include a mount that allows the speaker to hang, e.g., like a pendant, from a support, which may be mounted to a building, on the ground, on a deck, on a dock or the like.
An outdoor loudspeaker may include audio circuitry and lighting circuitry, which may be connected to separate signal sources. The lighting circuitry may produce light from a light signal source. The audio circuitry may produce audio from an audio signal source. The lighting circuitry and the audio circuitry may be in a housing that protects both from the outside environment, e.g., sun, rain, moisture, mechanical contact.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
This application claims the benefit of U.S. provisional application Ser. No. 62/326,107 filed Apr. 22, 2016, the disclosure of which is hereby incorporated in its entirety by reference herein.
