Title: Double 360° sounding resonant portable audio device
Inventor: MEI QINGKAI
IPC: H04R1/40
Filed: 2012-07-27
Abstract: Disclosed is a double 360° sounding resonant portable audio device. The resonant portable audio device comprises a housing, and a resonant sound generator and a printed circuit board (PCB) disposed in the housing. The improvement lies in that, a sound cavity is formed in the housing, and at least three speakers which are electrically connected to the PCB circuit board are disposed in the sound cavity. The beneficial effects of the present invention are, conventional speakers are integrated in the existing resonant audio device, and a plurality of speakers is disposed in the cavity of the resonant audio device; the combination of the plurality of speakers generates a multi-directional sound effect, which is different from the directional sound effect of a single speaker. The resonant audio device combined with the plurality of speakers can achieve a double 360° sounding effect generated by the resonant 360° sounding and traditional speaker combination 360° sounding, thereby improving the sound experience of the resonant audio device greatly.

Abstract: An air stop valve of an airtight body (1), comprising: a first outer membrane (2a) and a second outer membrane (2b) that are stacked together, a first air stop valve arranged between the first outer membrane (2a) and the second outer membrane (2b). An air inlet passage (2d) of the air stop valve is arranged at an air column end and is heat sealed. Another heat-resistant material (1c') is coated between a first inner membrane (1a) and the second outer membrane (2a) of the air stop valve. The first inner membrane (1a) and the first outer membrane (2a) are heat sealed without being attached to each other to form another air inlet passage (2d'). The first inner membrane (1a) is provided on the surface thereof at a predetermined position with a plurality of linear geometrically patterned valve pieces (1a'). This allows the air inlet passage (2d) and the other air inlet passage (2d') to form a bend in an air passage. As such, when the internal pressure of a gas that enters an air column (11) is sufficiently strong, the bent air passage can then be tightly affixed together, thereby sealing the air column (11), thus preventing the gas sealed in the air column from back flowing through the original air passage, and achieving the optimal long-term airtight effect.

Abstract: La présente invention se rapporte à un procédé et à un système adaptés pour protéger un service en rapport avec une liaison composite, ladite liaison composite comprenant deux liaisons membres, ou plus. Le système selon l'invention comprend des nœuds de chaque liaison membre. Lesdits nœuds sont configurés de façon : à détecter l'état de liaison de la liaison membre ; et à transmettre un message de notification à un module de commande de la liaison composite quand il est détecté que le service de la liaison membre est congestionné ou que sa bande passante se modifie.
