BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to the docking speaker with the wireless charger thereon, and particular to the docking speaker with the speaker system intermixing with the wireless charger without substantial vibration due to the sound generated by the speaker.
2. Description of Related Art
Both U.S. Pat. Nos. 9,184,619 and 9,343,837 disclose the docking speaker with the wireless charger thereon for not only playing the music but also charging the smart phone wirelessly at the same time. To enhance the sound quality, the woofer is used in the speaker system of the docking speaker, and the woofer may introduce the relatively significant vibration during playing the music. Anyhow, the wireless charging is very susceptible to vibration which can shift the phone's position relative to the center of the charging coil. Notably, the charging efficiency depends on the phone being centered on the charging coil. In addition, the high volume associated with vibration may also cause the phone to move causing potential rattling noise. Both the aforementioned two patents fail to pay attention to this potential defect because both of them have the pair of speakers mounted upon the same side of the case which inevitably results in the vibration and this drawback gets worse when the speaker gets the high volume.
It is desired to have the docking speaker with the wireless charger thereon without substantial vibration due to the speaker system.
SUMMARY OF THE INVENTION
A docking speaker includes a case enclosing a pair of push-push woofers located around two opposite lateral sides and outwardly facing away from each other, a wireless charging module located between the pair of push-push woofers in the transverse direction and forming an upward oblique seating face on which the smart phone is adapted to be positioned, and a full range speaker located between the pair of push-push woofers in the transverse direction and aligned below the wireless charging module in the vertical direction when viewed along the front-to-back direction. A first printed circuit board is located on a lower portion of the case and is connected with an external power wire. A second printed circuit board is located on an upper portion of the case in compliance with the oblique seating face and mechanically and electrically connected to the wireless charging module. A third printed circuit board is located on the upper portion of the case and in front of the second printed circuit board, and mechanically and electrically connected to the panel button and the microphone.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-12, a docking speaker 100 includes a hollow case or housing 10 having a tubular main body 12, a base 14 and a ceiling part 16. A pair of push-push woofers or speaker drivers 20 are located around two opposite lateral sides of the case 10, and aligned with and outwardly facing away from each other in the transverse direction. A wireless charging module 30 with a charging coil therein (not shown) is located between the pair of push-push woofers 20 in the transverse direction. A forwardly facing full range speaker or primary speaker driver 40 is located between the pair of push-push woofers 20 in the transverse direction, and not only aligned with and located below the wireless charging module 30 in the vertical direction perpendicular to the transverse direction when viewed along a front-to-back direction perpendicular to both the transverse direction and the vertical direction, but also aligned with and located in front of the wireless charging module 30 in the front-to-back direction when viewed in the vertical direction. A first/main printed circuit board 50 is positioned upon the base 14. A power wire 52 is connected to the first printed circuit board 50 and extends through the base 14 and toward the anterior. The speaker system including the pair of woofers 20 and the full range speaker 40, is controlled by the first printed circuit board 50. A second printed circuit board 60 and the wireless charging module 30 associated therewith, are positioned upon an underside of the ceiling part 16. A third printed circuit board 70 is also positioned on an underside of a panel region 160 of the ceiling part 16 and in front of the second printed circuit board 60 wherein the operation panel region 160 has two through vents 164 aligned with the microphones 74 on the third printed circuit board 70, and marked touching regions between the two vents 164 operated with conductivity switches by finger touch, and the third printed circuit board 70 has pads 72 corresponding to such touching switches. An interior cover 80 is assembled under the ceiling part 16 so as to cooperate with the ceiling part 16 to form therebetween a space in which both the second printed circuit board 60 and the wireless charging module 30 are enclosed. Understandably, both the second printed circuit board 60 and the third printed circuit board 70 are electrically connected to the first printed circuit board 50 via internal wires wherein an internal wire 90 is partially shown. Notably, the ceiling part 16 provides a charging area on the upward seating face 162 on which the cellular phone (not shown) is positioned for wireless charging.
The feature of the invention is to provide the push-push woofers 20 on opposite sides of the case 10 to eliminate the vibration due to the speaker system and the full range/primary speaker 40 and the charging area are located in a center region between the pair of push-push woofers 20 in a symmetrical manner. Accordingly, there is less or even no vibration due to the whole speaker system while playing the music, thus assuring the wireless charging efficiency. Understandably, in this embodiment there is only one wireless charging module between the pair of push-push woofers 20. Anyhow, additional wireless charging modules may be provided as long as the pair of push-push woofers are also symmetrically arranged with regard to such additional wireless charging modules.
