Abstract:
An apparatus for comprehensive perception of sound, preferably a cushion, where vibration and sound is produced with a mechanical device wrapped inside a padding (100). The device radiates sound by generating mechanical vibration directly to the padding that can be felt and listened on the outer surface of the padding. The device radiates airborne sound through the padding. In order to avoid acoustical and mechanical resonances, the padding comprises an acoustically denser and lossy layer (110) and a layer (120) that is acoustically less dense and porous. The device comprises at least one board (300), and the vibration of the boards is generated using at least one vibrating mechanical actuator (400).
Abstract:
A personal voice-transmitted device includes at least one voice box and at least one voice-transmitted tube. The voice box has a speaker arranged therein, and is divided to a first space and a second space by the speaker. The voice-transmitted tube connects to one side of the voice box and extends outwardly and has an outlet. The device can generate and retain a low-pitched tone by resonance of the first space, and the low-pitched tone can be transmitted to the outside by the voice-transmitted tube to form an excellent low-pitched tone. The drawbacks of the prior art such as poor tone because of using an earphone, a shutting stress and an uncomfortable feeling because of inserting an earphone, an unsafe feeling because of hanging an earphone and a sanitation problem because of contacting an earphone can be improved. The device can be used with no restriction on occasions and time.
Abstract:
A headphone assembly is provided that includes two earpieces coupled by a flexible connecting wire. Each earpiece includes a single large button disposed on a distal side of the earpiece, thereby enabling a wearer to operate the system, even without direct access thereto.
Abstract:
Methods and products for activating a backpack audio-visual system are generally described. In an example, a module in the backpack may detect a presence of a device in a first compartment that may be defined by a first set of walls. In response to the detection, the module may determine a status of a first speaker and a second speaker. The first and second speakers may be inside of a second compartment and a third compartment, respectively. The second and third compartments may be defined by a second and a third set of walls, respectively. Based on the presence of the device in the first compartment and the status of the first and second speakers, the module may establish a wireless communication link between the device and the first and second speakers. The backpack audio-visual system may be activated in response to the establishment of the wireless communication link.
Abstract:
The present invention relates to a microphone comprising a transducer (20) for transforming acoustic or vibratory oscillations into an electrical signal; a preamplifier (24) for amplifying the electrical signal, and a controllable switch (25) arranged electrically between the transducer (20) and the preamplifier (24), the switch (25) being able to be controlled by a drive signal, the preamplifier (24) comprising an input terminal (60) connected directly to a terminal (56) of the transducer (20), the microphone being able to transmit the amplified electrical signal to a transmission and feed device (13). Furthermore, the present invention relates to a mask comprising such a microphone.
Abstract:
Disclosed is an acoustic speaker (1) including a plurality of loudspeakers (10), a flexible element (2) for supporting the loudspeakers, and a flexible sheath (5) for external coating of the loudspeakers and the flexible supporting element.
Abstract:
A portable, flexible cover connected between a source of signals such as an MP3 player and headphones, the flexible cover comprising a substantially flat and flexible surface encapsulating a conductor yet substantially resting on a surface or on the body of a wearer and have a design to mask the conductor and minimize tangling thereof.
Abstract:
An apparatus, comprising a heat-retaining shell defining a receptacle and an opening in communication with the receptacle, the heat-retaining shell forming a receiving portion configured to receive at least a portion of the ear of the user; a speaker disposed within the receptacle of the shell; and a first electrical wire disposed in the receptacle of the shell, the first electrical wire having a first end electrically coupled to the speaker and a second end including a connector, the connector being disposed proximate the opening of the shell and configured to be electrically coupled to a second electrical wire disposed outside of a housing of the device associated with sound generation.
