The present invention relates to a speaker resonance apparatus, and more particularly, to a speaker resonance apparatus for securing a resonance space for improving acoustic performance of a speaker.

In recent years, due to the development of the electronic communication industry, such portable terminals as mobile communication terminals (cellular phones), electronic notebooks, personal digital assistants (PDAs), and the like have been enhanced with various multimedia functions in order to satisfy the needs of users. For example, a speaker unit capable of implementing melody of various chords is installed, and a color display device of several million pixels is implemented. In addition, a music listening function through an MP3 player other than a basic call function is implemented in a terminal, and a digital multimedida broadcast (DMB) function for receiving air waves as well as various game contents using the display device is provided.

At this time, the portable terminal is becoming smaller and lighter, and it is becoming more difficult to secure the internal space. In particular, a speaker unit that performs information transmission through sound to a user generally has an internal resonance space that has already been determined, and is composed of variable sound quality depending on sound control. However, the characteristics of the sound output from the speaker using the predetermined resonance space do not satisfy the user's satisfaction. For example, due to the thinning of the portable terminal, the sound output from the speaker using a small resonance space does not satisfy the bass characteristics required for music, movies, etc., which may cause user dissatisfaction.

An object of the present invention is to provide a speaker resonance apparatus that can improve the acoustic performance by expanding the speaker resonance space of the portable terminal.

Provided by the rotation to provide a speaker resonance device characterized in that the resonance space of the speaker unit is variable.

As a third aspect for solving the above problems, the present invention provides a portable terminal comprising a main body and a sub body sliding on the main body to open and close the portable terminal, wherein the sub body accommodates a speaker unit, and the speaker A main housing including an opening through which the sound generated by the unit is discharged, and a sub housing rotatably connected at an angle to one end of the main housing so as to resonate the sound generated by the speaker unit. Formed, the sub housing is rotated in the main housing as the sub body is opened and closed in the main body, thereby providing a portable terminal characterized in that the resonance space is variable.

By using the speaker resonance apparatus according to the present invention, the portable terminal can be made thin, but the speaker resonance space can be variably enlarged to improve the acoustic performance of the speaker.

Hereinafter, the operating principle of the present invention will be described in detail with reference to the accompanying drawings.

10 is a view showing a schematic structure and operation of another speaker resonance apparatus according to an embodiment of the present invention in a slide portable terminal.

Referring to FIG. 10, the slide portable terminal includes a main body 710 and a sub body 720 that slides in the main body 710 to open and close the portable terminal. In particular, as shown in the speaker resonance apparatus 700 according to an embodiment of the present invention, when the sub body 720 slides in the main body 720, the resonance space is automatically generated by the aforementioned elastic means. Is expanded.

The speaker resonator device 700 is included in the sub body 720 and may receive a pin at one end of the main enclosure case frame 730 (main housing) and the main enclosure case frame 730 that may accommodate a speaker unit (not shown). 250 is coupled to include a sub enclosure case frame 740 (sub housing) that can rotate at an angle with respect to the pin 250.
