摘要:
A system and method for providing and/or controlling air flow to an air sensor. As a non-limiting example, an air sensor system may include mechanical and/or electromechanical features (e.g., MEMS features) to control air flow to an air sensor. Various aspects of the disclosure may, for example, be implemented in a personal electronic device.

An electro-acoustic transducer is provided that comprises a diaphragm and a magnet assembly comprising a magnet and a back plate. The back plate comprises at least one first vent. The diaphragm generates sound during a movement of the diaphragm relative to the back plate. The transducer further comprises a printed circuit board comprising at least one second vent and a cavity between the printed circuit board and the back plate that separates the at least one first vent from the at least one second vent.

An electronic system and an electronic device thereof are provided. The electronic device includes a first housing, a speaker module, a second housing, and a bearing. The first housing has a first hole. The speaker module is disposed in the first housing, and a sound generated by the speaker module is transmitted out of the electronic device through the first hole. The second housing has a bearing surface facing to the first housing. The bearing is disposed between the first housing and the second housing. The second housing and the first housing move relative to each other by using the bearing, so the first housing covers or exposes a portion of the bearing surface.
摘要:
A computer system having a loudspeaker mounted on a main logic board by a hermetic seal, is disclosed. More particularly, embodiments of the computer system include an acoustic cavity defined between the loudspeaker, the main logic board, and the hermetic seal. Embodiments of the computer system may include a compressible seal separated from the hermetic seal by the loudspeaker and/or the main logic board. The compressible seal may define an acoustic channel and the loudspeaker may emit sound in a high frequency range through the acoustic channel toward a system exit. Other embodiments are also described and claimed.
摘要:
An electronic device whose enclosure or housing panel is used as part of an acoustic system is described. The panel is divided into several sub-panels. For each sub-panel, the device includes one or more actuators attached to vibrate the sub-panel. The actuator and its attached sub-panel convert an audio signal to acoustic output. Each actuator and sub-panel combination may receive a separate audio signal. The device includes a digital signal processor for controlling each of the sub-panel driving audio signals. The device may further include one or more backing frames that are attached to the panel to provide boundary conditions to the sub-panels. The boundary conditions define a resonance frequency for each sub-panel.
摘要:
A signal processing system for controlling a lower frequency acoustic range of an acoustic output of a loudspeaker system. The system includes an input to receive at least a first channel audio signal, corresponding to the acoustic output of at least one loudspeaker with at least one electro-acoustic transducer with a vibratile diaphragm. The signal processing system includes at least one transpositional gain controller processor for transposition of at least a portion of the amplitude of at least one band of frequencies in a lower frequency audio signal range of the audio signal, to an increased gain in at least one transpositional target frequency in the lower frequency audio signal range. The transpositional gain controller processor includes at least one of at least one, static or dynamic, transpositional gain controller. The system may include at least one additional signal processor, supporting preservation of a perceived fidelity of the acoustic output.
摘要:
A loudspeaker audio accessory provides and non-cable interface to a portable radio. The accessory can operate in conjunction with the radio or as a standalone device. An accessory loudspeaker is contained within the accessory housing, the accessory loudspeaker being positioned at a tilted angle within the housing to direct audio upwards towards audio porting located on a top surface of the accessory housing. The accessory provides a plurality of operational modes, the first mode of operation being a stand-alone mode generating an emergency alert audio tone via the loudspeaker in response to a switch being enabled; and the second mode of operation provides boosted audio via the accessory loudspeaker when the accessory is coupled to a radio. The accessory can also operate in conjunction with the radio via a short range link to selectively emergency signals and boosted audio.
摘要:
An audio device incorporates a plurality of acoustic drivers and employs them to form either a first acoustic interference array generating destructive interference in a first direction from the plurality of acoustic drivers or a second acoustic interference array generating destructive interference in a second direction from the plurality of acoustic drivers in response to the orientation of the casing of the audio device relative to the direction of the force of gravity.
摘要:
A loudspeaker device (200) is presented which includes a zeolite material (100) comprising zeolite particles (102) having a silicon to aluminum mass ratio of at least 200. For an increased pore fraction of pores with a diameter in a range between 0.7 micrometer and 30 micrometer shows an increased shift of the resonance frequency down to lower frequencies has been observed.
