The present application relates to a sound production unit and a speaker. The sound production unit includes: a frame, where the frame has a receiving space; a magnetic path system, where the magnetic path system is arranged in the receiving space, and a magnetic gap is formed in the magnetic path system; a vibration system, where the vibration system includes a first diaphragm and a second, a first voice coil assembly inserted into the magnetic gap to drive the first diaphragm to vibrate to produce a sound, and a second voice coil assembly inserted into the magnetic gap to drive the second diaphragm to vibrate to produce a sound; and an end cover. Vibrations of the sound production unit or the speaker and the like can be counteracted; cophase stacking can also be performed on sound waves; and the acoustics effect of the speaker is enhanced.

Various embodiments of the present invention relate to a microphone, an electronic apparatus including the microphone and a method for controlling the microphone, the electronic apparatus comprising: a substrate comprising a first hole and a second hole into which an audio signal is input; a case that has a resonance space formed thereinside as a first side thereof is opened, a second side thereof is closed, and the first side is coupled with the substrate; a first audio generation unit that converts an audio signal input through a first hole of the substrate into an electrical signal, and comprises a first plate and a first membrane spaced apart from each other; a second audio generation unit that converts an audio signal input through a second hole of the substrate into an electrical signal, and comprises a second plate and a second membrane spaced apart from each other; a sound insulation wall that is disposed between the first audio generation unit and the second audio generation unit, and separates spaces of the first audio generation unit and the second audio generation unit as a first side thereof is coupled with the case and the second side thereof is coupled with the substrate; a microphone that is electrically connected to the first audio generation unit and the second audio generation unit, and comprises a signal processing unit for removing a noise signal exceeding a threshold value by analyzing the audio signals transmitted through the first audio generation unit and the second audio generation unit; and a processor that is electrically coupled with the microphone, wherein the sensitivity of the first audio generation unit is configured to be lower than the sensitivity of the second audio generation unit, so that the microphone can correctly receive the user's audio command by removing noise greater than or equal to a predetermined level. Various embodiments other than the various embodiments disclosed in the present invention are possible.

An assembly may include a speaker supportable for movement relative to a reference external to the speaker and a speaker housing supporting speaker components operable to produce an audio output. A sensor is operable to sense a direction of movement of the speaker during movement of the speaker relative to the reference. Control components are operable to control the speaker components based on the direction of movement of the speaker relative to the reference. When the speaker is sensed to be moving in a first direction relative to the reference, an operational characteristic of the speaker components is controlled to increase or advance during movement in the first direction. When the speaker is sensed to be moving in a second direction relative to the reference different from the first direction, the operational characteristic of the speaker components is controlled to decrease or retreat during movement in the second direction.

Provided is a multifunctional image-shooting and sound-receiving device, including a controller, a built-in microphone, a switching unit, an adjustment unit, a drive unit, a sensor and a motor. The built-in microphone is connected to the controller and receives at least one microphone sound signal. The switching unit is connected to and transmits a switching signal to the controller. The adjustment unit is connected to and transmits an adjustment signal to the controller. The drive unit is connected to and receives a drive control signal from the controller. The sensor is connected to and receives a sensing control signal from the controller, and transmits sensing information thereto. The motor is connected to and receives a driving signal from the drive unit, and integrated with a lens. The controller switches the multifunctional image-shooting and sound-receiving device to one of a first mode and a second mode according to the switching signal.

A headset having game, chat and microphone audio signals is provided with a programmable signal processor for individually modifying the audio signals and a memory configured to store a plurality of user-selectable signal-processing parameter settings that determine the manner in which the audio signals will be altered by the signal processor.
