A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Protected microphone systems may include one or more dampeners, one or more cavities, or a combination thereof to minimize the vibration sensitivity of a microphone of the protected microphone systems. The dampeners, when present, may be constructed of a foam material or a thin metal material.

There is provided a speaker device 1 having a speaker unit 10 and an enclosure 30 in which a plurality of rod-shaped bodies 31 is integrally bonded to each other and which is arranged in a space behind the speaker unit 10. Thus, a sound wave output from the speaker unit 10 to the rear side thereof can be more effectively damped.

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.

A wearable speaker system includes a bellows tube that holds a weight inside, and a speaker unit where a space inside the speaker unit and a space inside the bellows tube communicate with each other. The bellows tube is accommodated in the enclosure, and both end portions of the bellows tube are fixed to the enclosure.

An earphone with a first acoustic cavity, an electro-acoustic transducer configured to deliver acoustic energy into the first acoustic cavity, and a port that acoustically couples the first acoustic cavity to a different volume, wherein the port comprises a series of through-holes that are open to the first acoustic cavity and the different volume.

A symmetric dual suspension speaker structure is herein disclosed, comprising a basin frame, a U-shaped iron, a magnet permeability ferrite ring, a corrugated rim, a diaphragm, a sound coil, a damper clamped between the magnet permeability ferrite ring and the U-shaped iron, as well as a magnet, wherein the peripheral edge around the upper surface of the diaphragm can be stretched in the vertical direction to form a barrel component, and the corrugated rim is used to bond and fix the top end of the barrel component while the damper is used to bond and fix the bottom end of the barrel component, such that the sound coil can bring the barrel component of the diaphragm to vertically vibrate thus improving the instability existing in the bonding of the conventional diaphragm and the coil framework.

A cable assembly for electronic devices such as cellular telephones and music devices is disclosed. The cable assembly can comprise either one or two earpieces, each of which is configured to be received into the concha of a user's ear. The earpiece(s) can be configured so as to be held in place by at least one anatomical structure of the concha. A speaker can be in acoustic communication with each earpiece. A cable can be configured to communicate a signal representative of sound from the electronic device to each earpiece. A microphone can be permanently attached or removably attachable to the cable to facilitate use with a cellular telephone. The cable assembly can facilitate hands free operation of a cellular telephone and can facilitate listening to a music device. Other implementations and related methods are also disclosed.
