Abstract

The utility model discloses sound box expansion structure of a movable electronic device. The sound box expansion structure comprises a body and a sound module, wherein a chamber is concavely formed towards the inside of the surface of the body; and the sound module is correspondingly inserted into the chamber of the body and optionally moves towards the inside and outside of a shell along the chamber. In this way, the sound module serves as a space for resonant repeating noise and is further optionally moved out of the body, so that the sound repeating space can be further expanded to the chamber of the body. The aim of increasing the internal sound repeating space of the sound box is fulfilled so as to improve the volume and tone quality of the electronic device.

To achieve the above object, the present invention provides an audio amplifier extension structure for a mobile electronic device, comprising:

a main body, which is a housing of a mobile electronic device and has a chamber recessed inward on a side surface; and a sound source correspondingly disposed in the chamber of the body, and the sound source can selectively move along the chamber toward the inside and outside of the housing, the sound source further comprising a housing and a sound source unit; wherein the shell frame is externally matched and penetrates through the accommodating chamber, and a sound box space is arranged in the shell frame; wherein the sound source unit is correspondingly arranged at the front end of the shell frame.

Wherein, the inner ring wall surface of the containing chamber is provided with a first thread; and the outer ring wall surface of the shell frame is provided with a second thread corresponding to the first thread, and the shell frame is screwed in the containing chamber.

Wherein, the wall surface of the chamber of the body can also be provided with at least one guide groove, and the outer ring wall surface of the shell frame can be provided with at least one sliding rib corresponding to the guide groove.

Wherein, the section of the chamber is annular.

The mobile electronic device is a mobile phone.

Wherein, the sound source unit is a loudspeaker.

Adopt the utility model discloses a portable electronic device's audio amplifier expands structural design, its sound source ware except that original audio amplifier space can regard as the space that the sound produced sympathetic response and convolute, the user more can be when needing bigger volume or promotion tone quality, selectively with the sound source ware from pulling out on the body or screw out, to further let the space that can supply the sound to convolute expand the appearance room to the body from the audio amplifier space, see through this mode and reach the purpose that increases the inside reverberation space of audio amplifier, and then can improve this electronic device's audio amplifier volume and tone quality.

Detailed Description

In order to understand the creation features, contents and advantages of the present invention and the efficacy achieved thereby, the present invention will be described in detail with reference to the drawings and the expression of the embodiments, wherein the drawings are used only for illustration and the auxiliary specification, not necessarily for the actual proportion and the precise configuration of the present invention, and therefore, the scope of the present invention in actual implementation should not be read and limited with reference to the proportion and the configuration relationship of the drawings attached.

Referring to fig. 1 and 2, the present invention is a sound box expansion structure of a mobile electronic device, which comprises a main body 10 and a sound source 20 in a preferred embodiment.

The main body 10 is a housing of a mobile electronic device (e.g., a mobile phone), and a chamber 11 with an annular cross section is recessed from one side surface of the main body, and a first thread 111 may be disposed on an inner wall surface of the chamber 11.

Referring to fig. 3 and 4, the sound source 20 is correspondingly disposed in the accommodating chamber 11 of the main body 10, and the sound source 20 further includes a housing 21 and a sound source unit 22; the outer shape of the casing 21 is matched and passes through the accommodating chamber 11, a sound box space 211 is arranged inside the casing 21, and the outer annular wall surface of the casing 21 is provided with a second thread 212 corresponding to the first thread 111, so that the casing 21 can be screwed in the accommodating chamber 11, and the sound source 20 can selectively move towards the inside and the outside of the casing along the accommodating chamber 11; the sound source unit 22 may be a speaker, which is correspondingly disposed at the front end of the housing 21.

Referring to fig. 5, in an alternative embodiment, at least one guide groove 112A may be disposed on the wall of the chamber 11A of the main body 10A, and at least one sliding rib 213A corresponding to the guide groove 112A may be disposed on the outer annular wall of the housing 21A, so that the sound source 20A can move in the chamber 11A corresponding to the main body 10A.
