Problems solved by technology

However, these disclosed mechanisms rely on complex hydraulic or pneumatic systems with integrated check valves, air bladders, on / off valves, etc.
These mechanisms are therefore quite expensive and complicated to manufacture, resulting in high cost
Additionally, these mechanisms are difficult for the user to operate due to the user's need to manipulate small parts

Embodiment Construction

[0031] Figure 1-4 Four different views of a first embodiment of a sound emitting device according to the invention are shown. The first embodiment 1 is used as a wireless headset for a mobile phone. The headset 1 comprises a housing 2 , 3 consisting of an outer half 2 and an inner half 3 . The inner half 3 of the housing comprises an earpiece portion 4 which fits inside the user's ear canal (not shown). The earplug part 4 is covered by an expandable element 5 which in this particular example is a hollow sleeve made of elastic material such as rubber. When fluid is pumped into the hollow sleeve 5, the sleeve expands. When the earplug is placed in the user's ear canal and the hollow sleeve is expanded, the material of the hollow sleeve is pressed against the inner surface of the user's ear canal. In this way, the earplug is held securely in the user's ear. In turn, the expandable element adapts itself to the current user's ear canal. When the user wants to remove the head...

Abstract

A sound emitting device (1;20;40) of the kind which is arrangeable at the ear of a user and which comprises an earpiece portion (4;23;42) which fits inside the ear canal of the user. The earpiece portion comprises an expandable portion (5;24;43) which upon expanding expands against the inside surface of the ear canal of the user. The sound emitting device further comprises a compressible element (7;25;45) which is filled with a fluid and which is connected to said expandable portion whereby fluid is transferred to said expandable portion causing it to expand upon compression of said compressible element. The sound emitting device further comprises a compression mechanism (6;26,27;46,49,50) for compressing the compressible element and which is adjustable by the user to adjust the amount which the compressible element is compressed. In this way, a simple and robust device is provided which is easy for the user to adjust. It is also easy to manufacture.

Description

technical field [0001] The invention relates to a sound-generating device that can be arranged on the user's ear. The sound generating device includes an earplug portion adapted to be placed within an ear canal of a user, the earplug portion including an expandable portion that expands against an inner surface of the user's ear canal when inflated. This holds the device securely in the user's ear and increases the volume reaching the user's eardrum. The sound generating device also includes a compressible element filled with fluid and connected to the expandable portion. When the compressible portion is compressed, fluid is transferred from the compressible element to the expandable portion causing the expandable portion to expand. [0002] Related Technical Notes [0003] Sound generating devices of the type mentioned above have been disclosed in the patent literature, but are not readily available on the market. This type of equipment can be used for many different purpo...
