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: An acquisition method and system for clinical experimental data, an electronic device, and a storage medium are provided, which relate to the field of data processing technologies, the method includes: extracting first clinical experimental data from a target information system based on a preset clinical experimental data extraction model; acquiring and labeling speech input data and manual input data of a target user to obtain second clinical experiment data; recognizing to —be-extracted clinical experimental data based on a preset character recognition model to obtain third clinical experimental data; organizing and arranging the three clinical experimental data in chronological order and weight to generate ultimate clinical experimental data.

Abstract: A press fitting includes a pipe connector, a nipple, a check ring, a sealing ring, a pressure sleeve. The pressure sleeve is locked within the check ring, which has an inlet groove, a positioning annular groove connected with the inlet groove, and the positioning annular groove has larger internal diameter than that of the inlet groove. The pressure sleeve has an extension section on its end, and the dimension of the external diameter of the larger-diameter end of the extension section is between the dimension of the internal diameter of the inlet groove of the check ring and that of the internal diameter of the positioning annular groove of the check ring. The press fitting involves good coaxiality between the pressure sleeve and the check ring, good fixity of the pressure sleeve, and can be operated easily and utilized widely in industrial applications.

Abstract: The present utility model discloses a press fitting, comprising a pipe connector, a nipple, a check ring, a sealing ring, a pressure sleeve, etc. Said check ring is sleeved into the end groove at the end section of said nipple of said pipe connector. Said sealing ring is fit to the sealing groove of said nipple. The pressure sleeve is locked within said check ring, which has an inlet groove, a positioning annular groove connected with said inlet groove, and said positioning annular groove has larger internal diameter than that of said inlet groove. Said pressure sleeve has an extension section on its end, and the dimension of the external diameter of the larger-diameter end of said extension section is between the dimension of the internal diameter of said inlet groove (124) of said check ring (12) and that of the internal diameter of said positioning annular groove (123) of said check ring (12).
