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> discloses a loudspeaker system. <CIT> discloses a micro-speaker having an air adsorbent. <CIT> discloses a sound absorption material and loudspeaker box. <CIT> discloses an audio speaker having a rigid adsorptive insert.

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 the electronic device, sounds having opposite phases may be produced in a first direction (e.g., a rear surface) and a second direction (e.g., a front surface) of the diaphragm. Therefore, in order to prevent and/or reduce destructive interference due to the opposite phases of the first and second directions, the electronic device may be designed to separate a first space formed in the first direction and a second space formed in the second direction with respect to the diaphragm.

The diaphragm of the speaker module equipped in the electronic device may be limited in vibration due to the resistance of ambient air, so that the sound reproduction efficiency may 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.

Embodiments of the disclosure provide an electronic device including an air adsorption member disposed in a certain space (e.g., a rear space) of a housing in which a speaker module is mounted. The air adsorption member facilitates compression and relaxation of air, thereby minimizing and/or reducing air resistance to a diaphragm disposed above the speaker module without limiting the vibration of the diaphragm. In addition, this may secure a reliable amplitude of the diaphragm and thereby improve a sound quality of a low frequency band.

According to various example embodiments of the disclosure, an electronic device is included according to Claim <NUM>.

Also disclosed is an electronic device which includes: a diaphragm; a speaker module comprising at least one speaker configured to output a sound through a vibration of the diaphragm; a housing accommodating the diaphragm and the speaker module therein, the housing including a first housing disposed at an upper position of the electronic device and a second housing disposed at a lower position of the electronic device, the housing including a first space provided in a first direction from the speaker module, and a second space provided in a second direction opposite the first direction; and an air adsorption member comprising an air adsorption material disposed in at least a part of the first and/or the second housing or disposed between the first and the second housing, and configured to adsorb air in the first space and/or the second space.

Embodiments of the disclosure may provide an electronic device including an air adsorption member disposed in a certain space (e.g., a rear space) of a housing in which a speaker module is mounted. The air adsorption member facilitates compression and relaxation of air, thereby minimizing and/or reducing air resistance to a diaphragm disposed above the speaker module without limiting the vibration of the diaphragm. In addition, this may secure a reliable amplitude of the diaphragm and thereby improve a sound quality of a low frequency band.
