Abstract: A speaker device is provided. The speaker device includes a frame, a vibration unit and a magnetic circuit unit. The vibration unit and the magnetic circuit unit are fixed to the frame. The magnetic circuit unit is configured to drive the vibration unit to vibrate to produce sound. The magnetic circuit unit includes a yoke. The yoke and the frame are spaced to form a leakage port. The vibration unit includes a diaphragm, a voice coil, and an elastic support assembly. The auxiliary diaphragm has one end fixed to the frame and the other end connected to the voice coil. The auxiliary diaphragm is provided with multiple vents spaced and penetrating the auxiliary diaphragm. The present disclosure can increase the circulation of gases above and below the auxiliary diaphragm, so that a side leakage effect of the speaker device is improved, thereby improving acoustic performance of the speaker device.

Abstract: An electronic device includes an accommodation and a receiver. The accommodating piece defines a first cavity and a second cavity communicated with the first cavity. A first sounding hole and a second sounding hole communicated with outside are respectively defined on two opposite walls of the first cavity. The receiver is installed in the first cavity. The receiver includes a first diaphragm and a second diaphragm disposed opposite to first diaphragm. The first diaphragm faces the first sounding hole. The second diaphragm faces the second sounding hole. The first diaphragm vibrates to generate a first sound signal, the second diaphragm vibrates to generate a second sound signal, and a phase of the first sound signal is opposite to a phase of the second sound signal. Parts of sound signals generating sound leakage are compensated and counteracted through an algorithm, and a user has a good private call experience.

Abstract: A speaker device is provided. The speaker device includes a frame, and a vibration unit, a magnetic circuit unit, and air-permeable isolation member. The magnetic circuit unit includes a yoke fixed to the frame. The yoke and the frame are spaced to form a leakage port to enable leaking from a side surface of the speaker device. The sound-producing inner cavity communicates with the leakage port. The air-permeable isolation member completely covers the leakage port. The leakage port communicates with the outside through the leakage hole. Compared with the related art, the speaker device of the present disclosure has a yoke leakage structure, which can realize self-sealing and is conducive to assembling.

Abstract: A JAK inhibitor may be used in preparation of a medicament. The medicament may be used for preventing and/or treating a disease or condition associated with an antitumor agent in a subject. A pharmaceutical composition may include the JAK inhibitor as may a kit. The JAK inhibitor may include a compound of formula (I) or a pharmaceutically acceptable salt thereof: Q, X, Y, and Z being independently N or C, and R1, R2 and R3 being independently a 5-6-membered aromatic ring, 5-6-membered heteroaromatic ring, 5-6-membered cycloalkyl, 5-6-membered heterocycloalkyl, amino, or amido, the aromatic ring, heteroaromatic ring, cycloalkyl, and/or heterocycloalkyl being optionally substituted by a substituent.

Abstract: The present invention provides a speaker box including a housing with a sound hole and a speaker therein. The speaker includes a frame, a vibration system, a magnetic circuit system, and a covering shell. The vibration system includes a diaphragm dividing a receiving room of the housing into a front cavity communicating with the sound hole and a rear cavity, a voice coil assembly. The magnetic circuit system includes a yoke. The covering shell divides the rear cavity into a first rear cavity inside the speaker and a second rear cavity outside the speaker. The covering shell includes a bottom wall and a side wall. A recessing portion formed on the side wall, and the recessing portion communicates the first rear cavity with the second rear cavity.
