Patent number: 10194235Abstract: This invention discloses a kind of speaker structure with a loading hole. A characteristic is that it includes an active cavity that has a cone hole and a loading hole; a loudspeaker is sealed and secured on the said cone hole; the said active cavity is connected to the outside air through the said loading hole; the cone of the said loudspeaker has one side which is connected to the free space; another characteristic of this invention is that it includes a driven cavity that is connected to the said active cavity through the said loading hole; the cross-sectional area of the said loading hole is smaller than the cross-sectional area of the air passage on its either side; further, it is not larger than ? the effective area of all the vibration units in the said active cavity; also, the volume of the said active cavity does not exceed half the total volume of the said active cavity and driven cavity. The loading hole constitutes a loading component which improves the transient response of the speaker body.Type: GrantFiled: June 19, 2013Date of Patent: January 29, 2019Assignee: TGI TECHNOLOGY PTE LTDInventor: Shihuang Li

Publication number: 20180359547Abstract: The present invention discloses a speaker enclosure, in particularly a blown molded hollow pressure vessel. The present invention discloses a speaker enclosure, which is formed at once and sealed better. The thickness of the enclosure can be very thin and hence reduce the weight of the speaker. The present invention discloses a speaker enclosure, which can use many of the existing products to replace the traditional speaker enclosure. The present invention discloses a speaker enclosure, which its audible unit directly connects to the blow opening tightly. The present invention discloses a speaker enclosure, which its audible unit is provided with a seal. When the audible unit and speaker enclosure are assembled, the seal and enclosure opening thereby are completely tight assembled together.Type: ApplicationFiled: November 15, 2016Publication date: December 13, 2018Inventor: Shihuang LI

Patent number: 10070216Abstract: This invention provides a kind of acoustic structure that uses passive diaphragm unit, it includes speaker unit, passive diaphragm unit, radiant tube; said passive diaphragm unit is located at the back of the cone of said speaker unit; the speaker unit has radiant tube on the sides; the said radiant tube end which is exposed in the air is located at the periphery of the cone of said speaker unit. It has the same orientation as the speaker unit; the said passive diaphragm unit vibrates when it is driven by the said speaker unit, the sound waves produced by the vibration of the said passive diaphragm unit are emitted by the radiant tube and radiant opening, and share the similar vocal point of the said speaker unit. With this, the sound effect of the full range sound is almost identical to the sound point sources, it also reduces the phase difference between the sound effects produced by the cone of speaker unit and the passive diaphragm unit, further enhanced the sound positioning feature.Type: GrantFiled: January 28, 2014Date of Patent: September 4, 2018Assignee: TGI TECHNOLOGY PRIVATE LIMITEDInventor: Shihuang Li
