Patent number: 7837335Abstract: A projector includes a lamp, a fan for dissipating heat generated by the lamp, a housing, a number of blades received in the housing, and a elongated-slider. The housing receives the lamp and the fan, and includes a top cover, a sidewall connected to the top cover, and a bottom cover connected to the sidewall. The top cover defines an through opening therein. The blades can be rotated in cooperation with the slide of the elongated-slider in the through opening. As described above, the projector can exhaust thermal formed by the lamp or electronic elements from the air outlet. At the same time, the flow direction of the air from the air outlet can be changed in cooperation with the slider. Therefore, when a user sits by the air outlet, the user can adjust the flow direction of the air from the air outlet at any time.Type: GrantFiled: March 10, 2008Date of Patent: November 23, 2010Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Wen-Fu Wen, Kai Huang

Publication number: 20090320533Abstract: An exemplary locking structure for a portable electronic device includes an engagement portion and a fastener. The engagement portion includes an upper plate and a lateral plate perpendicular to the upper plate. Two protrusions are fixed on a fringe of the upper plate and lateral plate. The lateral plate defines a through hole. The fastener includes a main body, a first holding sheet, two second holding sheets, and a third holding sheet. The main body abuts the lateral plate. The first and second holding sheets extend from the upper plate in a first direction and the second holding sheets are engaged with the protrusions. The third holding sheet extends from a bottom end of the main body and passes through the through hole so that a locking hole of the third holding sheet is exposed outside of the housing.Type: ApplicationFiled: December 10, 2008Publication date: December 31, 2009Applicants: PREMIER IMAGE TECHNOLOGY(CHINA) LTD., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: ZHUO-GUANG RUAN, WEN-FU WEN

Publication number: 20090096998Abstract: A projector equipped with an illuminated logo region includes a light source including a reflector defining an opening and a light-emitting portion contained by the reflector, a light-modulating device, a lens, a housing, and a logo region. The light-emitting portion emits light radially. Part of the light is emitted directly through the opening of the reflector and/or is reflected by the reflector through the opening to be received by the light-modulating device to be modulated to produce a projecting light before being received by the lens and then projected to form an image on a surface. Another part of the light is transmitted through the reflector to illuminate the logo region. The housing is configured for housing the light source, the light-modulating device, and the lens. The logo region is inlaid in a portion of the housing corresponding to the reflector, to be illuminated by the another part of light.Type: ApplicationFiled: April 21, 2008Publication date: April 16, 2009Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: WEN-FU WEN, KAI HUANG

Publication number: 20090065673Abstract: A speaker holder includes a base with a blocking portion, a restraining plate, and two flanges extending form a same side of the base. The restraining plate is separated from the blocking portion. The restraining plate has an inward restraining tab at an end of the restraining plate remote from the base. The blocking portion, the restraining plate, and the two flanges cooperatively form a receiving space for receiving and restraining the speaker on the base. The speaker can be directly inserted into the receiving space and more easily and firmly fixed therein utilizing the restraining tap of the restraining plate. Therefore, time spent to assemble the speaker is less than the conventional method.Type: ApplicationFiled: April 3, 2008Publication date: March 12, 2009Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: WEN-FU WEN
