Patent Description:
With a great variety of portable electronic devices such as smart phones popularized, various modules that perform particular functions are being provided in the electronic devices. For example, the electronic device may include at least one speaker module for outputting sounds. The speaker module may convert an electrical signal generated at the electronic device into an audible sound signal through the vibration of a diaphragm and output the sound signal.

<CIT> relates to a micro speaker in which air adsorbent prevents a phenomenon in which a sound pressure is reduced by blocking a ventilation hole.

<CIT> relates to an apparatus comprising an agglomeration of adsorbing members, each of the adsorbing members comprising a porous outer layer configured to enclose an amount of adsorbent material, the agglomeration being configured such that every cross-section through the agglomeration comprises at least one gap between adjacent adsorbing members.

<CIT> relates to an audio speaker having an adsorptive insert in a speaker back volume. An adsorptive insert has a rigid open-pore body formed by bonded adsorptive particles. The rigid open-pore body includes interconnected macropores that transport air from the speaker back volume to adsorptive micropores in the bonded adsorptive particles during sound generation.

<CIT> relates to an apparatus including: a loudspeaker configured to convert an electrical input signal into an acoustic output signal; and carbon nanohorn material wherein the carbon nanohorn material is positioned so as to be exposed to the acoustic output signal.

<CIT> relates to a process comprising: placing a raw powder of a porous sound-absorbing material into a heating furnace to perform calcination, and introducing a processing gas during the calcination, wherein the calcination temperature is <NUM>° C. to <NUM>° C. , and the calcination time is <NUM> to <NUM>.

<CIT> relates to a sounding device. The sound production device comprises a sound production body, the sound production body comprises a vibrating diaphragm, the vibrating diaphragm is provided with a front surface and a back surface, and the vibrating diaphragm is configured to be capable of vibrating to produce sound and transmitting the sound out of the sound production body from one side of the front surface of the vibrating diaphragm; And the sound absorption particles are arranged in the sound production body and/or between the sound production body and an external part, and the sound absorption particles are communicated with the back surface of the vibrating diaphragm.

<CIT> relates to a loudspeaker having a framework with a plurality of openings therein, fitted with an elastic body of a bitumen-containing urethane foam over the rear side of the framework to absorb the acoustic energy transmitted rearwardly from the speaker.

As the thickness of the electronic device becomes thinner, the speaker module as well needs to be thinner. When the speaker module becomes thin, a vibration space of the diaphragm may be narrowed. In addition, when the vibration space of the diaphragm is narrowed, the diaphragm may be limited in vibration due to the resistance of ambient air existing in the speaker module. This may cause the sound reproduction efficiency to be lowered. For example, when the vibration of the diaphragm is limited, the sound output through the speaker module may be reduced or the sound quality may be degraded.

The above-mentioned drawbacks are solved with a speaker module according to claim <NUM>. Optional features of the module are defined in the dependent claims.

Embodiments of the disclosure provide a speaker module including an air adsorption member that facilitates compression and relaxation of air and thereby minimizes and/or reduces air resistance to a diaphragm without limiting the vibration of the diaphragm. In addition, embodiments of the disclosure provide an electronic device including the speaker module.

According to various example embodiments of the disclosure, a speaker module includes: a yoke defining one surface of the speaker module; a magnet attached to the yoke through a first surface of the magnet; a plate attached to a second surface of the magnet; a frame providing a lateral surface of the speaker module and combined with the yoke at a first end of the frame; a voice coil disposed to be spaced apart from the magnet; and a diaphragm combined with the voice coil at an inner surface of the diaphragm. In the speaker module, at least one of the yoke, the magnet, the plate, and
the frame include at least a portion of an air adsorption member comprising an air adsorption material configured to adsorb air in the speaker module based on the diaphragm vibrating.

According to various example embodiments of the disclosure, an electronic device may include: a housing providing at least a part of a lateral surface of the electronic device; and a speaker module including a speaker accommodated in the housing.

According to various example embodiments of the disclosure, at least some other components of the speaker module, not only the frame, may be formed of or combined with the air adsorption member, and therefore it is possible to minimize and/or reduce air resistance to the diaphragm and thereby output an optimum sound.

In addition, minimizing and/or reducing air resistance to the diaphragm of the speaker module may secure a reliable amplitude of the diaphragm and thereby improve a sound quality of a low frequency band.
