摘要： An MEMS microphone includes a substrate including a back volume provided inside the substrate and an opening provided at an upper surface of the substrate to communicate the back volume; a sensing device provided at an inner side wall of the back volume; a first cantilever provided inside the back volume and including end portions coupling with the sensing device; a first membrane provided at the opening; a second membrane provided inside the back volume; and second cantilevers, each of which includes a first end mechanically supporting the first cantilever, and a second end connected to the second membrane. By suspending the first cantilever on the second cantilevers, the end portions of the first cantilever always couple with a preset position of the sensing device. Thus, the DC offset of the displacement of the membrane can be prevented.

摘要： A speaker and a method of producing a speaker, the speaker including: an enclosure; at least one transducer mounted in the enclosure; and at least one passive radiator mounted in the enclosure, including a suspension and a center panel encircled by and adhered to the suspension, wherein the at least one transducer is combined with the at least one passive radiator, and functions as at least a part of the center panel. According to the speaker of the present disclosure, by fully or partly replacing the center panel of the at least one passive radiator by one or more transducer(s), both the internal space and the cost of the speaker are saved without sacrificing the sound quality.

摘要： A plurality of acoustically-driven mechanically-coupled tuned-closed-column-resonator-tuned-Helmholtz-resonator-piezo-poly-passive-radiator-electromagnetic-induction-circuit vibrational and acoustic piezoelectric resonator systems constitute an acoustic energy harvesting device that mechanically amplifies induced sound pressure levels via standing wave resonance such that the anti-node/s of the natural resonant frequency/ies in the tuned-closed-column-resonator/s occur/s in the plane/s consistent with the coupling port/s of the attached tuned-Helmholtz resonator/s and subsystems, acoustically driving the tuned-Helmholtz resonator/s of physical parameters such that standing wave resonance occurs within the tuned-Helmholtz resonators one wall of which comprises a sympathetically oscillating poled-piezo-polymer-surround-mounted-non-poled-piezo-polymer tympanic membrane the face/s of which is/are mounted with thin film ferromagnetic solenoids that derive electric fields from the oscillating poled-piezo-polymer surround to self-induce magnetic fields oscillating through stationary inductor coil/s housed in the throat connecting the tuned-Helmholtz resonator-piezo-poly-passive-radiator-electromagnetic-induction-circuit to the subsequent mechanically-coupled tuned-closed-column-resonator-tuned-Helmholtz-resonator-piezo-poly-passive-radiator-electromagnetic-induction-circuit and mechanically-coupled tuned-closed-column piezo-ceramic-resonator/s and tuned-piezo-ceramic-Helmholtz-resonator/s and subsystems generates electricity, magnetic fields, and is self-sustaining.

摘要： A multifunctional sound device includes a housing, a sound unit, and a motor assembly. The sound unit includes a frame, a vibration system, and a magnetic circuit system. The motor assembly includes a vibration unit and elastic components. The vibration unit includes driving coils and a mass block. The driving coils are fixed to the mass block and located in a magnetic field range of the magnetic circuit system. The mass block is made of conductive materials. The driving coils interact with the magnetic circuit system to enable the vibration unit to vibrate in a reciprocating mode after the driving coils are energized. Compared with related art, the multifunctional sound device is small in overall thickness and size, large in electromagnetic damping of a magnetic circuit, easy to assemble, and excellent in acoustic performance.

摘要： A speaker box includes a housing; a speaker unit accommodated in the housing, the speaker unit including a diaphragm for vibration and sound producing; a front sound cavity formed cooperatively by the diaphragm and the housing; a sound guiding channel communicating the front sound cavity with external environment; a front cavity formed by the front sound cavity and the sound guiding channel; a through hole penetrating the housing and disposed at a position on the housing corresponding to the front cavity; and an elastic cover plate arranged on a side of the housing far from the speaker unit and covering the through hole for absorbing vibration energy at a specific frequency. A Young's modulus or strength of the elastic cover plate is smaller than that of the housing.

摘要： The present disclosure generally provides an apparatus and method of forming a liquid impermeable sealed audio speaker that can be easily manufactured and provides a high quality audio output. In an effort to overcome the shortcomings of conventional sealed speaker designs that typically utilize complicated and expensive means of shielding their electronic components from liquids and other sources of contamination, one or more of the embodiments of the disclosure provided herein include a sealed enclosure that has at least one liquid impermeable region that prevents or substantially inhibits the movement of a liquid from the exterior region into the internal region. In general, the liquid impermeable regions, or hereafter simply “liquid permeable regions,” are configured to prevent the ingress of liquids or other contaminants, while allowing the production of a desired sound quality.

摘要： An earphone includes a housing having a sound-emitting hole, a speaker mounted in the housing, and a passive radiator mounted in between the sound hole and the speaker driver and including a vibrating diaphragm main body and a weight embedded in the vibrating diaphragm main body or bonded to the top or bottom surface of the vibrating diaphragm main body. The mounting arrangement of the passive radiator optimizes the sound performance of the earphone. The weight of the passive radiator is firmly connected with the vibrating diaphragm main body so that severe vibration of the vibrating diaphragm main body does not cause disconnection of the weight.

摘要： An improved electrically conductive membrane pump/transducer. The electrically conductive pump/transducer includes an array of electrically conductive membrane pumps that combine to move a larger membrane (such as a membrane of PDMS).
