Embodiment Construction

[0041] figure 1A mobile phone 1 is shown as an example of a mobile device. The mobile phone 1 may comprise a microphone, a wireless transmitter-receiver unit, an amplifier, and a central processing unit connected to the wireless transmitter-receiver unit and to the amplifier.

[0042] Mobile device 1 included in figure 2 Speaker 21 shown in . The amplifier of the mobile phone 1 can be connected to the speaker 21 .

[0043] The loudspeaker 21 includes at least one dynamic driver 22 . Dynamic drives themselves are known to the skilled person. A dynamic driver typically includes a magnetic circuit system, a diaphragm movably mounted relative to the magnetic circuit system, and a voice coil attached to the diaphragm. The magnetic circuit system includes a magnet, and the voice coil is operatively coupled to the magnet. If an electrical signal, eg generated by an amplifier, is applied to the voice coil, the diaphragm moves in response to the electrical signal.

Abstract

A loudspeaker comprises an enclosure, at least one dynamic driver mounted in the enclosure, and at least one porous monolithic block. The at least one porous monolithic block comprises a plurality ofpores and is mounted within the enclosure.

Description

technical field [0001] The present invention relates to loudspeakers and methods of making loudspeakers. The present invention also relates to a mobile device, such as a mobile phone, comprising a loudspeaker. Background technique [0002] European Patent No. 2424270 B1 discloses a loudspeaker comprising a housing and a dynamic driver mounted in the housing. The shell is filled with zeolite material. Filling the outer shell with zeolite material results in a significant substantial increase in the volume defined by the outer shell, ie in increasing the effective volume of the outer shell. The zeolite material includes particles having an average particle size ranging from 0.2 mm to 0.9 mm and having a plurality of zeolite particles adhered together by a binder. The zeolite particles contain micropores and have a mass ratio of silica to aluminum of at least 200. SUMMARY OF THE INVENTION [0003] It is an object of the present invention to provide a loudspeaker comprisin...
