DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Embodiments of the present invention provides a portable speaker for a music player such as an iPod® player. The housing of the speaker is shaped and sized as a cup and can be placed inside a commonly seen cup holder, such as a cup holder in a car or other vehicles, a baby stroller, a foldable camping chair, etc. The speaker housing has a slot for receiving a music player, as well as electrical connectors for electrically connecting to the audio output of the music player. The sound producing devices are enclosed within the speaker housing and face upwards and/or downwards.
FIGS. 1a-1d are side, front, back and top views of a speaker 10 according to an embodiment of the present invention. The housing 11 of the speaker 10 has a cylindrical or slightly tapered cylindrical outer shape, with an outer diameter of approximately 2 to 3.5 inches and a height of at least 2 inches. In one particular embodiment, the housing 11 has an outer diameter of about 2.5 inches at the bottom and about 3 inches at the top, and a height of about 3 inches. The diameter of the housing 11 is selected such that the housing will fit inside a cup holder of commonly seen size without too much gap between the housing and the cup holder. Common cup holders have a diameter of approximately 2.5 to 3.5 inches. Of course, a speaker having the general shape as shown in FIGS. 1a-1d may have a larger or smaller diameter if it is designed to fit in a cup holder of a special size that is larger or smaller than commonly seen cup holders.
In a preferred embodiment, the housing 11 is made of a rigid material such as plastics. In another embodiment, the housing 11 may be made to have a layer of compressible materials such as foam or resilient materials such as spring plates on its outside, so that the housing can fit into cup holders of different sizes. In yet another embodiment, the housing may be made to have adjustable diameters.
In the particular embodiment shown in FIGS. 1a-1d, the housing 11 has a top portion 11a that has a larger diameter than the lower portion of the housing. When the housing 11 is inserted into a cup holder, the top portion 11a is above the rim of the cup holder. The shape of the top portion 11a is a design choice; alternatively, the top portion 11a may be omitted and the entire housing may have a substantially uniform diameter or a tapered shape.
A slot 12 is provided that extends from the top surface of the housing 11 into the interior of the housing for receiving a music player 20. The slot 12 may extend vertically down or may be slanted. The size and shape of the slot 12 may be designed to fit a music player of a particular size and shape, or designed to have a sufficiently large size to accommodate music players of commonly seen sizes and shapes. In one embodiment, the slot is approximately 2 to 3 (preferably 2.5) inches deep, 2.5 to 2.75 inches wide and 1⁄2 to 5⁄8 inches thick. The depth of the slot is not important, so long as the music player can securely sit inside the slot. The music player 20, which is not a part of the speaker 10, is inserted into the slot when the speaker is in use, and can be removed when the speaker is not in use.
FIG. 2 schematically illustrates the internal structures of the speaker 10. As shown in FIG. 2, one or more electrical connectors 13a, 13b are provided inside the slot 12 and/or on an outside surface (e.g. the top surface) of the housing 11. In one implementation, the speaker 10 is designed for use with a music player 20 that has a pin connector on its bottom with pre-defined mechanical and electrical specifications. A pin connector 13a having corresponding mechanical and electrical specifications is provided at the bottom of the slot 12 and can mate with the connector of the music player. The music player 20 is firmly inserted into the slot 12 so that the connectors of the music player and the speaker are electrically connected with each other. In another embodiment, a plug hole 13b is provided on the top surface of the housing 11 so that an adaptor cable (not shown) can be plugged into the plug hole to electrically connect the music player 20 with the speaker 10. The speaker 10 may have both connectors 13a and 13b or only one of them.
One or more sound producing devices 16 (sometimes also referred to as speakers), electrical circuitry 15, and batteries (optional, not shown) are housed within the housing 11. The circuitry 15, is electrically connected to the connectors 13a, 13b, receives output audio signals from the music player 20 and controls the sound producing devices. In a preferred embodiment, one sound producing device is located near the top surface of the housing 11 facing upwards. The top surface of the housing 11 is provided with a plurality of orifices 14 (see FIG. 1d), or is partially made of a mesh material, to facilitate the propagation of the sound. In one embodiment, a second sound producing device is provided near the bottom of the housing facing downwards, and the bottom surface of the housing 11 may also be provided with orifices (see FIG. 1e) or a mesh material.
In one embodiment, the speaker housing 11 has a battery compartment, so that the speaker can be used without being connected to an external power source. In another embodiment, the speaker 10 has a power cord or can receive a power cord from an external power source, such a 12V source of a vehicle.
As smart tablet devices such as tablet computer, e-reader, etc. become more widely used, there is a need for convenient holders designed to hold such devices in various situations. These smart tablet devices tend to be larger than pure music players such as iPodTM or devices such as smart phones. Second through fourth embodiments of the present invention provide smart tablet device holders that are integrated with, or cooperate with, two cup-shaped speakers, and that can be used with baby strollers, in particular, parent trays of baby strollers. A parent tray is a tray located just below the push handle of a stroller, in front of the person pushing the stroller. Some parent trays of conventional strollers are provided with two cup holders side by side for the convenience of the parent. A smart tablet device holder incorporating two cup-shaped speakers can be used by inserting the two speakers into the two cup holders of the parent tray. While the parent tray of a stroller is used as an example here, the smart device holder may also be used with the child tray of the stroller or other types of trays that have two cup holders side by side.
FIG. 3 illustrates an exemplary smart tablet device holder integrating two cup-shaped speakers according to the second embodiment of the present invention. As shown in FIG. 3, the smart tablet device holder 110 includes two cup-shaped speakers 30A and 30B, and a bridge member 40 located between the two speakers 30A and 30B. The bridge member 40 is mechanically connected to and supported by the two speakers 30A and 30B, and may be formed integrally with the two speakers. For example, the top portions 31A and 31B of the speakers 30A, 30B and a part of the bridge 40 may be formed of one piece of material such as plastic. The two speakers 30A, 30B have cup-shaped housings 32A, 32B extending below the bridge member 40. In use, the housing 32A, 32B of the speakers are inserted into the two cup holders of the parent tray of the stroller, while the bridge piece 40 is disposed above the tray surface between the two speakers. The bridge member 40 has structures designed to hold a smart tablet device, as will be described in more detail later.
Each of the speakers 30A, 30B has a structure generally similar to the cup-shaped speaker 10 of the first embodiment shown in FIGS. 1a-2, except for the following differences. First, the slot 12 of speaker 10 is not necessary for the speakers 30A and 30B, because the music player (the smart tablet device) can be held by the bridge member 40. Of course, the slot 12 can still be provided to make the holder 110 more versatile. Second, the electrical connector 13a or 13b shown in FIG. 2 may now be located on the bridge member 40, such as the electrical connector 41 shown in FIG. 3. The electrical connector 41 can also be located on the top portion 31A 93 31B of the cup-shaped speaker. One such electrical connector is coupled to the electrical circuitry of both speakers 30A and 30B.
The structure of speakers 30A, 30B is otherwise similar to that of the speaker 10, including the two sound producing devices facing upwards and downwards, the orifices on the top and bottom cover of the speakers (the orifices 33A, 33B on the top surface are shown in FIG. 3), the exterior shape and size of the housing, etc.
The bridge member 40 may have various shapes; any suitable shape may be used, so long as it can stably hold a smart tablet device. In the example shown in FIG. 3, the bridge member 40 includes a flat bottom piece 42 connecting the two speakers 30A, 30B, and a top piece 43 pivotally joined to the bottom piece 42 by a hinge (not shown), so that the top piece can rotate (as indicated by the arrow C) between an open position (shown in FIG. 3) where the top piece is substantially vertical and a closed position (not shown) where the top piece is substantially horizontal and rests over the bottom piece. The rotation axis of the top piece 43 in this example is in a transverse direction, i.e. parallel to a line extending between the centers of the two speakers 30A, 30B. When the top piece 43 is open, it forms a back of the holder and the smart tablet device can be disposed upright, resting on the bottom piece 42 and against the top piece (back) 43. A ridge 44 or a groove may be provided on the top surface of the bottom piece 42 extending in the transverse direction, so that the bottom edge of the smart tablet device can rest against the ridge or sit in the groove, preventing the tablet device from sliding. Optionally, retaining devices such as clamp(s), hook(s), strap(s), elastic band(s), etc. are provided on the back 43 to securely retain the smart tablet device to the holder. The smart tablet device can be electrically connected to the internal circuitry of the speakers 30A, 30B via the electrical connector 41. When not in use, the top portion 43 may be rotated to its closed position.
In an alternative implementation, the top piece 43 is fixedly joined to the bottom piece 42 and not rotatable. The top piece is substantially vertical, forming a back of the holder. In other words, the bridge member 43 has an L-shaped cross-section.
FIGS. 4a-4c schematically illustrates another example of a smart tablet device holder according to the third embodiment. This holder 120 includes two cup-shaped speakers 50A, 50B similar to the speakers 30A, 30B, and a bridge member 60 connecting the two speakers. The bridge member 60 is preferably formed integrally with the two cup-shaped speakers 50A, 50B. The bridge member 60 has an elongated shape extending between the two speakers, as shown in FIGS. 4a and 4b (front elevation view and top view, respectively), and a U-shaped cross-section as shown in FIG. 4c. The U-shaped cross-section forms an elongated pocket in which the smart tablet device (shown in dashed lines in FIG. 4c) can be held. Retaining devices such as clamp(s), hook(s), strap(s), elastic band(s), etc. may be optionally provided on the bridge member 60 to secure the smart tablet device to the holder.
An electrical connector (not shown) is provided on the bridge member 60 and/or one or both of the cup-shaped speakers 50A, 50B, and is electrically connected to the electrical circuitry of the speakers 50A, 50B.
In an alternative implementation, the back panel of the bridge member 60 is made higher, forming an asymmetrical pocket, as shown in the cross-sectional view FIG. 4d. Such a pocket can hold the smart tablet device more securely.
FIG. 5 illustrates another smart tablet device holder system using two cup-shaped speakers 10A, 10B and a bridge member 70 according to a fourth embodiment of the present invention. Each of the two cup-shaped speakers 10A, 10B may be identical to the sub-shaped speaker 10 of the first embodiment (see FIGS. 1a-2). The bridge member 70 is a separate piece, i.e., not integrated with the speakers 10A, 10B. The bridge member 70 has an elongated shape with two round openings 71A, 71B which have locations and sizes that match the locations and sizes of the cup holders 210A, 210B of the tray 210 (which is not a part of the smart tablet device holder system). This structure allows the bridge member 70 to cooperate with the two cup-shaped speakers. In use, the bridge member 70 is placed over the tray 200 so that the openings 71A, 71B are aligned with the cup holders 210A, 210B of the tray 200. The two cup-shaped speakers 10A, 10B are then placed through the openings 71A, 71B into the cup holders 210A, 210B to hold the bridge member 70 in place. Preferably, as shown in FIG. 5 as well as FIGS. 1a-1c, each speaker 10A, 10B has a top portion (11a in FIG. 1a-1c) that extends outwardly beyond the diameter of the housing (11 in FIGS. 1a-1c) of the speakers, so that when the speakers 10A and 10B are placed firmly in the cup holders, the bridge member 70 is sandwiched between the top rim of the cup holders 71A, 71B and the top portion of the speakers 10A, 10B.
The bridge member 70 has a holding structure located in the back (behind the two openings 71A, 71B), which is formed of two substantially vertical panels 72 and 73, disposed at a distance from each other, forming a pocket having U-shaped cross-section for holding the smart tablet device 300. The smart tablet device 300 (which is not a part of the holder system) may rest in a substantially vertical position inside the U-shaped pocket. Preferably, the bridge member 70 is formed of one piece of plastic material.
As stated earlier, bridge member of the smart tablet device holder may have any suitable shape; while two specific examples are given in FIG. 3, FIGS. 4a-4c and FIG. 5, other designs can be used and the invention is not limited to these examples.
It will be apparent to those skilled in the art that various modification and variations can be made in the speaker with music player adapter of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
