Abstract:
The present invention is a microphone that incorporates a system of removable covers that can change the acoustic characteristics of the microphone, provide enhanced environmental protection for the microphone, and add additional features through electronic sensors and other means. The invention consists of one or more microphone capsules mounted inside of an enclosure, which has a physical fastening system such as flanges, screw threads, or other means. This fastening system mates with a variety of microphone covers that can change the characteristics of the microphone. These covers may act as wind screens, acoustic baffles, phase cancellation guides, water and dust seals, impact bumpers, and may also add additional functionality through the incorporation of electronic sensors
Abstract:
A microphone head device includes a microphone head, a mount and a vibration-absorbing unit. The mount includes amount ring surrounding the microphone head, and a plurality of annularly spaced-apart support rods projecting axially from the mount ring. The vibration-absorbing unit includes a surrounding body sleeved fittingly on the microphone head and having one end inserted between the microphone head and the mount ring, and a plurality of annularly spaced-apart hollow posts connected to the surrounding body and sleeved respectively on the hollow posts.
Abstract:
The multi-layered maternity band is an apparel item that is adapted for use during maternity. The multi-layered maternity band is a band that is worn around the enlarged abdomen of pregnant women. The multi-layered maternity band is a textile formed from sound absorbing material that protects the infant from exposure to exterior sounds. The multi-layered maternity band is further fitted with speakers that allows for the further use of sound cancelling technology or the playing of music for the infant. The multi-layered maternity band comprises a band, a first hook and loop fastener, a second hook and loop fastener, a pocket, a first speaker, a second speaker, and a signal cable.
Abstract:
A system for a seat in a motor vehicle that has a cabin audio system and a bass loudspeaker that is able to generate sound in the cabin. The system includes a seat active suspension system with a vibration sensor coupled to the seat, and a controller that is responsive to the vibration sensor and that outputs control signals that are provided to an electromagnetic actuator that reduces seat vibrations. The active suspension system is arranged such that it can cause a change in the audio system.
Abstract:
A semiconductor device includes a microelectromechanical system (MEMS) die, an encapsulation material, a via element, a non-conductive lid, and a conductive layer. The encapsulation material laterally surrounds the MEMS die. The via element extends through the encapsulation material. The non-conductive lid is over the MEMS die and defines a cavity. The conductive layer is over the MEMS die and the encapsulation material and is electrically coupled to the via element.
Abstract:
A portable electronic device may have acoustic ports such as microphone and speaker ports. Acoustic devices such as microphones and speakers may be associated with the acoustic ports. An acoustic port may have an opening between an interior and exterior of the portable electronic device. The opening may be covered by a metal mesh. An acoustic fabric may be interposed between the metal mesh and the opening. The opening may be formed from a hole in a glass member having outer and inner chamfers. A microphone boot may be provided that forms front and rear radial seals with a housing of the device and a microphone unit respectively. The microphone boot may also form multiple face seals with the microphone unit. A speaker for the speaker port may be enclosed in a sealed speaker enclosure. The speaker enclosure may have a pressure-equalizing vent slit covered with an acoustic mesh.
Abstract:
A pair of in-ear headphones is disclosed that are operable to reproduce incoming audio signals. The in-ear headphones include a housing defining an internal chamber. A front portion of the housing defines a nozzle extending away from the housing. A driver is positioned in the internal chamber such that a sound reproduction portion of the driver is aligned with an internal audio channel running through the nozzle. A damper is positioned in an end of the nozzle having a damper aperture having a predetermined size. The nozzle extends from a base portion of the housing at a predetermined upward angle and a predetermined bend angle that provides improved audio frequency responses in desirable frequency ranges.
Abstract:
There are provided an acoustic generator capable of generating a high-quality sound having little distortion, and an acoustic generation device and an electronic apparatus using the same. An acoustic generator has a vibration body, a first exciter, a second exciter, a first damping material and a second damping material. The vibration body has two surfaces which are positioned with a gap therebetween in a first direction. The first exciter and the second exciter are disposed on the vibration body. The first damping material is disposed on the vibration body and has a first portion which overlaps the first exciter when viewed in the first direction. The second damping material is disposed on the vibration body and has a second portion which overlaps the second exciter when viewed in the first direction.
Abstract:
An earphone with stand-alone high-frequency driver includes a casing, a low-frequency driver, a high-frequency driver, and a protecting cover. The casing defines a sound-guiding passage and a separating wall. The separating wall is formed on a side surface of the sound-guiding passage and defines a sound port, which is in communication with the sound-guiding passage. The high-frequency driver is disposed next to the separating wall and defines a sound-outputting direction. The protecting cover is mated to the casing and covers the high-frequency driver. The sound waves generated by both low- and high-frequency drivers are delivered externally through the sound-guiding passage. The earphone allows structural modifications and assembling the high-frequency driver and the protecting cover after a half-finished product (casing and low-frequency driver) is obtained. Hence, no major modification of the manufacturing processes is necessary, thus shortening the manufacturing time, lowering the manufacturing costs, and avoiding delay in product delivery.
Abstract:
An electro-acoustic driver including an acoustic waveguide includes an enclosure, an acoustic transmission line formed within the enclosure, and a plurality of acoustic transducers contained within the enclosure and disposed along a length of the acoustic transmission line. Each acoustic transducer is configured to emit acoustic energy directly into the acoustic transmission line at two separated locations along the length of the acoustic transmission line.
