Embodiment Construction

[0018] As single portable loudspeaker systems become increasingly compact, creating a sufficiently large acoustic volume within the system and providing sufficient surface area on the system housing in which the passive radiator and radiating surface of the electro-acoustic driver are located, and thereby achieve High quality audio output becomes a significant challenge. Removable components such as the internal battery module occupy the acoustic volume and compete for surface area of ​​the portable speaker system. The high pressure within the acoustic volume also requires a robust and resilient seal between the driver and / or passive radiator and the housing of the system. The examples described in this article address the above challenges.

[0019] refer to figure 1 , the portable speaker 100 includes a housing 105, and a first grill 110a along the front surface. In some examples, the housing is made of extruded aluminum and the grille 110a is made of steel. A series of b...

Abstract

A portable loudspeaker comprising a first electro-acoustic driver which, in operation, generates sound waves; a housing having a first side to which the driver is secured, and a second side opposite the first side; a first passive radiator, affixed to a first side of the housing, and a second passive radiator secured to a second side of the housing; and a single battery module removably affixed to the housing substantially located between the first and second In the area between the two passive radiators, the battery provides power to the driver, and the sound waves from the driver can acoustically excite the first and second passive radiators.

Description

technical field [0001] The present disclosure relates to audio devices, and more particularly to portable speakers. Background technique [0002] US Patent No. 8,098,867 to Hampton et al. discloses an external sound chamber (220) for attachment to a mobile device (200). The external sound chamber (220) optimizes the audio performance of the mobile device (200), thereby reducing the need for signal equalization and / or hardware for amplifying the sound signal. The mobile device (200) includes a speaker (205) and a first sound chamber (207) acoustically coupled to the speaker (205). The outer sound chamber (220) includes at least a second sound chamber (222) which penetrates the first sound chamber (207) thereby adding volume to the first sound chamber (207). The combined greater volume reduces the damping of the speaker (205) caused by the pressure within the first sound chamber (207). The result is that the frequency response of the loudspeaker (205) is improved by being c...
