Environmental sound is recorded using one or more microphones. A source of the recorded environmental sound is classified. The recorded environmental sound is weighted based on the classification of the source and the source media sound using a weighting mode to determine whether to mix the recorded environmental. The recorded environmental sound is mixed with source media sound to produce a mixed sound based on the determination. The mixed sound is played over one or more speakers.

A loudspeaker assembly for on-ear headphones, to be arranged on and/or over the ear, includes a housing in which a woofer is arranged and configured to emit low frequency sound waves along a low frequency sound beam axis toward the wearer's the ear. At least one tweeter is arranged in the housing and configured to emit high frequency sound waves along a high frequency sound beam axis toward the wearer's the ear. The at least one tweeter is a MEMS loudspeaker.

Embodiments are directed to a speaker system that contains an array of multiple dispersion drivers that creates an expansive acoustic pattern to playback multi-channel audio content through a standalone speaker. The speaker system comprises an interface receiving stereo audio; an upmixer generating surround sound formatted audio from the stereo audio including one or more height channels; a virtualizer/downmixer component coupled to the upmixer and generating speaker feeds for two or more loudspeaker output sections, configured to play back the stereo audio, wherein each output section is further configured to play its own dedicated stereo audio signals; and a set of drivers each coupled to a respective output section and configured to project sound in at least two different dispersion patterns.

The present disclosure discloses a loudspeaker and a method for improving directivity of a sound of a loudspeaker, a head-mounted device and a method for improving a sound effect of a head-mounted device. The loudspeaker comprises: a housing, a magnetic circuit unit that is provided within the housing and is for generating a magnetic force, a voice coil that vibrates by the magnetic force, and a vibrating diaphragm that in response to the vibration of the voice coil vibrates and generates a sound; wherein the loudspeaker further comprises a curved-surface extension structure; the curved-surface extension structure connects to the vibrating diaphragm, and radiating the sound generated by the vibrating diaphragm into a predetermined directivity range.

An apparatus and method of rendering audio. A binaural signal is split on an amplitude weighting basis into a front binaural signal and a rear binaural signal, based on perceived position information of the audio. In this manner, the front-back differentiation of the binaural signal is improved.

An electro-acoustic transducer includes: a housing; a fixed electrode; a diaphragm that oscillates in accordance with a potential difference between the diaphragm and the fixed electrode generated based on the electric signal, the diaphragm being provided to face the fixed electrode; and a support part that supports the partial region of the diaphragm toward the fixed electrode, the support part including a displacement part that is displaced in a direction in which the diaphragm is displaced in response to a change in pressure inside the housing, and a contacting part contacts the partial region of the diaphragm, wherein a distance between the diaphragm and the fixed electrode in the partial region is less than a distance between the diaphragm and the fixed electrode outside the partial region.

A user-programmable, head-supportable listening device with built-in WiFi media player is configured to provide user custom application programmability with higher fidelity sound provided by resident audio electronics and conduction speakers, in stereo and HD audio surround sound, the listening device having a user programmable electronics system assembly providing the ability to scan, detect, select and play audio and video from wired and wireless sources of audio and video signals, and from both residential media sources and online streaming music services, an audio media storage device to provide storage of user-selected media for accessing from the listening device or by an external wired and wireless device, which provides the user with control of speakers, wireless interfaces, automatic scanning capability and playing of audio-video media.

Disclosed are a button sound-emitting apparatus and an electronic device. The button sound-emitting apparatus comprises a cap part, a exciter, and an elastic component; said elastic component is arranged at an edge of the cap part; said exciter is provided in the middle of the cap part; the elastic component is connected to a housing of the electronic device; the exciter is suspended in the housing; the elastic component is configured for providing an elastic restoring force; the exciter is configured to be used for providing a driving force. The button sound-emitting apparatus is simple in structure and eliminates the need to arrange a front acoustic cavity and a sound outlet hole, and ensures good sound performance.

In device having at least one microphone and one or more speakers, environmental sound may be recorded using the microphone, classified and mixed with source media sound to produce a mixed sound depending on the classification. The mixed sound may then be played over the one or more speakers.

Systems and methods for generating a haptic output from an audio signal having a continuous stream of sampled digital audio data are provided. A haptic processing system receives the digital audio data, analyses the digital audio data for processing and extracts haptic signals for generating a haptic effect through an actuator. The method includes passing the digital audio signal on through dynamic processor(s), adjusting the dynamic range of the digital audio signal, extracting the signal envelope of the audio data, synthesising low-frequency signals from the extracted signal envelope, and enhancing the low-frequency content using a resonator. The haptic output is generated by mixing the digital audio signal with outputs from the different modules of the haptic processing system. An analytics module monitors, controls and adjusts the processing of the digital audio signal at the noise gate module, the compressor module and the envelope module to enhance the haptic output.
