The present invention relates to stands for mobile electronic device, and more particularly to stands with passive acoustic enhancement for an audio signal produced by the mobile electronic device.
Many mobile electronic devices, such as cellular telephones, include one or more internal speakers to allow a user of the device to listen to an audio playback on the device. The internal speakers have a limited audio output capacity.
Accordingly, means have been developed to amplify or enhance the audio output of the mobile electronic device. Typically, these will be active acoustic enhancement systems, incorporating an electronic amplifier circuit and a speaker. These active systems may also include equalizers, and the like, to enhance the audio system played on the speaker. The mobile electronic device is connected to these systems via a dock having an electronic connection between the mobile electronic device and the electronic amplifier circuit. These systems may include an internal battery source for power, or may include a power adapter for connection to an electrical power source, such as a wall outlet or a vehicle electrical system.
Other systems employ a passive acoustic enhancement incorporated in the stand that include various wave guide chambers to reflect the sound wave output of the internal speakers to develop a more robust audio signal from the output of the speakers. The wave guide chambers can be convoluted structures, which can increase the costs of manufacture for even a simple stand.
While many of these devices provide suitable listening to the audio output of the mobile electronic device, they do not support the device at an angle suitable for viewing a display of the portable electronic device.
As can be seen, there is a need for an improved stand for a mobile electronic device that provides a simplified construction for passive enhancement of the audio output of the mobile electronic device.
In one aspect of the present invention, a stand for a mobile electronic device is disclosed. The stand includes a front support surface and a rear support surface oriented in an inverted V shape with the respective surfaces angled at an inclined plane and joined along a common edge along an apex of the inverted V shape. The front support surface dimensioned to support a back surface of the mobile electronic device. An acoustic enhancement panel is joined along a side edge of the front support surface. The acoustic enhancement panel is angled forwardly of the front support surface and oriented to reflect an audio signal emitted by a speaker of the mobile electronic device forwardly of the stand.
In some embodiments, a front ledge extends along a lower end of the front support surface. A lip may protrude upwardly from the front ledge. A rear ledge may also extend along a lower end of the rear support surface. A lip may protrude uupwardly from the rear ledge.
In some embodiments, the front support surface and the rear support surface are movably joined along the apex. The angle of the front support surface and the rear support surface is adjustable between 5 degrees and 95 degrees.
In some embodiments, the acoustic enhancement panel is adjustably joined along the side edge of the front support surface. The acoustic enhancement panel may be adjustable between 5 degrees and 95 degrees.
In some embodiments, a charging aperture disposed through the acoustic enhancement panel, the charging aperture dimensioned to receive a charging connector of an electrical charging device. A battery pack may be carried on the rear support surface. A solar cell may be integrated with the battery pack to charge the battery pack. A charging cable may extend from the battery pack and through the charging aperture. The mobile electronic device may be carried on the front support surface. The charging cable is then connected to a charging port of the mobile electronic device.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention.
Broadly, embodiments of the present invention provides a stand for a mobile electronic device, such as a cell phone. The stand supports the mobile electronic device at an incline viewing angle so that a user may view a display of the mobile electronic device. The stand may also provide passive enhancement for audio signal produced by the mobile electronic device. The stand may also include a holder for a battery recharging system for the mobile electronic device. The battery recharging system may include a solar charging cell. The battery recharging system may also include a battery pack. The solar charging cell may include an integrated battery pack.
As seen in reference to the drawings of
The front stand support surface 12c and the rear stand support surface 12d are formed in an inverted V shape orientation with the respective surfaces angled at an inclined plane and joined at an apex along a common edge between the two support surfaces 12a, 12b. The inclined plane is angled at an angle to allow the user to view a display screen of the mobile electronic device 11a. A hinge or moveable connection along the apex may be provided to allow the inclined angle to be adjustable from 5° to 95°.
A passive acoustic enhancement panel 12e is disposed along a side edge at an end of the stand 10. The passive acoustic enhancement panel 12e is angled forwardly of the front support surface 12a. The passive acoustic enhancement panel 12e is oriented to reflect an audio signal 14 emitted from the mobile electronic device 11a forwardly of the stand 10, where the enhance acoustic signals may be heard by the user. The passive acoustic enhancement panel 12e is formed as substantially flat plate. The passive acoustic enhancement panel 12e has a depth of at least a thickness of the mobile electronic device 11a. The passive acoustic enhancement panel 12e may have a width at least as wide as an external speaker of the mobile electronic device 11a. More preferably, the passive acoustic enhancement panel 12e is at least that of the mobile electronic device 10.
In some embodiments, the passive acoustic enhancement panel 12e may also have a charging aperture 11c defined through a face of the panel 12e. The aperture is dimensioned to receive a charging connector a charging cord 11b. The charging cord 11b has a length to extend between a charging port connector of the mobile electronic device 11a, carried on the front support surface 12a of the stand 10 and a battery recharge device 11d carried on the rear support surface 12b of the stand 10.
The passive acoustic enhancement panel 12e can be adjustably attached to the front support surface 12, such as by using a hinge, an axis, a joint, a pin, or a ball and socket, to allow the passive acoustic enhancement panel 12e to be adjusted from 5° to 95° for acoustic adjustments and be able to hear the sound echo in a full range of sound.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
This application claims the benefit of priority of U.S. provisional application No. 62/922,763 filed Aug. 27, 2019, the contents of which are herein incorporated by reference.
