Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a detachable mobile sound source device, in particular, a sound source device, which is disposed on a backpack that enables a user to listen to music or broadcast from playback equipment while on the move.

2. Description of the Prior Art

Listening to music and melody is an enjoyable recreation for people, however, the public is able to enjoy music and melody at home, but has to carry a playback equipment, such as a sterro radio, a walkman and/or a MP3, with them while go mountain climbing or traveling. In addition, a user can merely listen to music alone through earphones, but unable to share music with others while engaging in outdoor activities; therefore, a conventional backpack structure of a prior art with mobile sound resource was deleloped.

With reference to FIG. 1, said conventional structure of a prior art enables two straps (11) on the front of a backpack (1) to have two loudspeakers (12) respectively embedded therein. Two pockets (13) are respectively disposed on the positions below each of said loudspeakers (12) as appropriate. Said backpack (1) has an amplifier (not shown) contained therein; said amplifier has a signal conducting wire pierce through a layer of the strap (11), connect said loudspeaker (12) and show a signal plug (14) on the upper fringe of either of the two pockets (13); therefore, the pocket (13) enables a playback equipment (15) to be contained therein and connected with said signal joint (14). When said playback equipment (15) is switched on, the signal is transmitted through said signal conducting wire, amplified by said amplifier and outputted by said loudspeaker (12), thereby a user is able to listen to music broadcasted by the loudspeakers (12), while carrying on the backpack (1) for mountain climbing or traveling.

Nevertheless, said conventional structure is found the drawbacks existed as follows from actual practices:

    • (A) applied only to a certain backpack device model: seeing that the conventional structure enables a playback equipment to be fixed in backpack straps, so that said conventional structure has to be used together with said backpack, resulting in limited selection of backpack brand and model of a user;
    • (B) lower application value: said conventional structure is suitable to be embedded inside said backpack straps for a user to listen to music or broadcast programs, which function is enabled at the same time when the said backpack is used for carrying things, if the backpack is not used, the function on the backpack does not have substantial economic effect;
    • (C) hard to be repaired or replaced: said conventional structure is embedded and fixed in the backpack straps, in case of a malfunction, the structure is unable to be dismantled from the backpack for repair; and
    • (D) fixed sound broadcast direction: the loudspeaker is fixed on the shoulder straps, so that sound is broadcasted towards a fixed direction.

In view of the foregoing, a “detachable mobile sound source device” of the invention is hereafter disclosed to achieve the practicability effect in the industry.

SUMMARY OF THE INVENTION

The main objective of the invention especially relates to a detachable mobile sound source device, which is able to be formed as either a U-shape ribbon or two sound units, comprising loudspeakers and a pocket for containing a playback equipment, such as a MP3. The detachable mobile sound source device has a coupling component set thereon for connecting a signal output line with said loudspeaker and being attached to said backpack or shoulder straps.

Said detachable mobile sound source device of the invention is, therefore, provided for a user to listen to music or broadcast from playback equipment while on the move.

Said mobile sound source structure of the invention enables a user to listen to music broadcasted by said loudspeakers.

With reference to FIG. 5, the invention is able to be applied to a strap across the chest (4), so that a user is able to directly wear on the body and enjoy the function of the invention on the move.

With reference to FIGS. 6A, 6B, 7 and 8, the invention mobile sound source device is able to be formed as two sound units (5), which comprises loudspeakers (50) and a pocket (51) that enables a playback equipment (6) to be contained therein. In addition, the units (5) has elastic (52) set on the back thereof and has a signal input hole (53) of a loudspeaker disposed on one end thereof. Accordingly, the elastic (52) of the units (5) is ale to directly fixed with the backpack with double shoulder straps (3) or shoulder straps (30), a hole (53) and a signal transmission line (54) that is concealed in the shoulder strap (30) of the backpack (3) are connected together with a microphone (55) exposed outside; thereby another preferred embodiment of the invention is provided. The invention is applicable to all backpack with double shoulder straps and shoulder straps (e.g. baby slings).

The invention comprises a simplified structure, so as to reduce the manufacturing cost; in addition, the invention is able to be detached from a backpack, so that the structure is convenient to be replaced or repaired.

The designs of said detached structure and related integrated applications enable the invention to have diversified combination manners for broadcasting music in multi-directions.

In conclusion, said “detachable mobile sound source device” of the invention makes use of the loudspeakers, transmission wire, a detached strap with a pocket set thereon to provide a flexible assembly for integrated or single-handed use, so that a user is able to listen to music or broadcast programs while climbing a mountain or engaging in an outdoor activity by applying the mobile sound source structure. Therefore, the invention possesses convenient and unlimited practical effect in the field.
