A case (1) for speakers comprising a hollow body (2), at least one hole (3, 4) communicating with the cavity (5) in the body (2) and defining a seat for at least one respective speaker is described. The case is characterized in that the body is a marble monolith.
摘要:
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).
摘要:
When an amplitude of vibration of a first diaphragm of a first speaker unit vibrated by applying a first and a correction AC signals having a frequency in a first frequency band to the first speaker unit is equalized to that of a second diaphragm of a second speaker unit vibrated by applying a second AC signal being the same as the first AC signal to the second speaker unit being the same as the first speaker unit attached to a closed type cabinet having the same internal volume as a speaker cabinet, a sound pressure reproduced by the first diaphragm is equal to or lower than that reproduced by the second diaphragm when a third AC signal having a frequency of a minimum resonance frequency or higher of the closed type cabinet determined by the internal volume thereof and the caliber of the second speaker unit is applied to the second speaker unit.

This disclosure relates to a system and method for producing a personalized earphone unit forming a comfort fit with ears of a user. The system comprises a mobile application installed in an electronic communication device and/or a website accessible by any networkable device for capturing images and video of the ears of the user. The images and video may be examined automatically using the mobile application and/or the website, and the video and/or images are uploaded to a server. The server stores and processes the images and video and sends them to a three dimensional printer unit for generating the personalized earphone unit. Audio electronic components are added to the personalized earphone unit for creating a functional and custom fit personalized earphone unit for an individual user that fit well into the ears. The system allows sharing and marketing of a plurality of designs and products of the earphone unit.

Provided are a sound amplification box and a sound amplification device. The sound amplification box includes a body including a predetermined resonance space therein and having a surface contacting an electronic device, a resonance hole formed in at least one surface of the body, and a vibration transmission part in a predetermined region of the surface contacting the electronic device.
摘要:
The invention relates to a loudspeaker unit comprising a loudspeaker housing and a first and a second loudspeaker, wherein the two loudspeakers are both placed in a flat front wall of the loudspeaker housing, the rear side of the first loudspeaker adjoins a first space in the loudspeaker box and the rear side of the second loudspeaker adjoins a second space in the loudspeaker box, and the first and the second space in the loudspeaker box are separated by a wedge-shaped body, the base of which is connected to a wall placed opposite the front wall and the intersection between the sloping surfaces of which is located in the vicinity of the front wall, wherein the wedge has a length in the direction transversely of the plane of the front wall that is at least twice the distance between the sloping surfaces at the position of the base of the wedge-shaped body.
摘要:
A shower and speaker assembly. The assembly may include a shower device including a device housing defining an inlet communicating with an inlet chamber, an outlet and a waterway communicating between the inlet chamber and the outlet, the device housing further defining a receptacle having a closed end and an open end, the inlet chamber being behind the closed end, the waterway extending along the receptacle from the closed end toward the open end; and a speaker supportable in the receptacle. The outlet may define an outlet plane, and the speaker may include a speaker housing providing a speaker outlet, the speaker outlet being one of aligned with and positioned forwardly of the outlet plane when the speaker is supported in the receptacle. The assembly may further include a magnetic connecting structure operable to releasably connect the speaker and the shower device.
