Abstract: An open-ear earphone includes a housing, a chamber is provided inside the housing, a speaker is provided inside the chamber and divides the chamber into a front chamber and a rear chamber. The housing is provided with a first sound hole and a second sound hole. The front chamber is communicated to the outside through the first sound hole, and the rear chamber is communicated to the outside through the second sound hole. The rear chamber includes a first volume down chamber and a second volume down chamber communicated to the first volume down chamber, and the first volume down chamber is located between the speaker and the second volume down chamber. The sound wave in backward motion generated by the speaker is transmitted to the outside from the second sound hole after being reduced by the first volume down chamber and the second volume down chamber.

Abstract: An open-ear Bluetooth® earphone includes an earphone body and a support frame. The support frame is configured to be plugged into a cavum concha of a wearer. The earphone body is provided with an audio source, and the support frame is installed on the earphone body and corresponds to the audio source. When in use, the support frame is configured to be firmly plugged into the cavum concha of the wearer to allow the earphone body to be worn on the ear of the wearer. The audio source corresponds to the ear canal of the wearer through the support frame, so that the sound emitted from the audio source is transmitted into the ear canal through the support frame. The audio source is directly opposite of the ear canal through the support frame to shorten the distance between the audio source and the ear canal.

Abstract: This invention provides a floating platform with canted columns, and a new method of mooring line makeup and installation method that can be used for the canted columns. In one embodiment, the platform includes 3 columns having upper ends projecting above water surface. The columns are canted or inclined inward from the corner of hull toward the top of column. The 3 columns converge at the top of column such that each column will lean against the other 2 columns. Each column connects to the other 2 columns. Horizontally disposed pontoons interconnect adjacent columns at the lower ends. The columns and pontoons form a closed structure hull to support a foundation structure directly above the top of column.

Abstract: We have invented a floating platform with 3 canted columns, a new type of fairlead, and a new method of mooring line makeup and installation method, that can be used for canted columns. The platform includes 3 columns having upper ends projecting above water surface. The columns are canted or inclined inward from the corner of hull toward the central vertical axis. The 3 columns converge at the top of column such that each column will lean against the other 2 columns. Each column has two connection points to the other 2 columns. Horizontally disposed pontoons interconnect adjacent columns at the lower ends. The columns and pontoons form a closed structure hull to support a foundation structure directly above the top of column.

Abstract: An acoustic system includes a receiver (or microphone), a tube, or a moisture resistant screen. The receiver is capable of outputting an audio signal, while the microphone receives an audio signal. The tube is in connection with the receiver (or microphone) and the audio signal travels along a length of the tube. The moisture resistant screen is fitted at an end of the tube. The moisture resistant screen prevents moisture from passing along the tube toward the receiver, and causes an amount of damping to the audio signal. The moisture resistant screen is configured to have a submersion rating greater than or equal to 7 IP.
