Patent Application
20070253589
The present invention relates to earphones, and more particularly, to an earphone that can regulate the sound properties of the earphone for adapting to anyone while listening versatile musical tones.
In general, the earphone is used more and more frequently for people. A conventional earphone comprises housing, a speaker and a signal wire. The housing contains the speaker and part of the signal wire. Some through holes are installed on the housing body essentially in the proximity of the speaker, to allow sounds of speaker generated to be emitted outward via the through holes. The housing is sealed except for the through holes. Limited to the predetermined capacity of the sealed housing, the sound effect amplified by the conventional earphone speaker becomes almost invariable in pitch property.
In view of the drawbacks of the conventional earphone, an innovative earphone is provided to regulate the sound properties of the earphone for adapting to anyone when listens versatile musical tones.
Accordingly, an object of the present invention is to provide an improved earphone to accommodate sound properties generated, such as high pitch and low pitch, to meet user criteria while listening versatile musical tones.
To achieve the above object, the present invention provides an improved earphone which comprises a speaker, a signal wire, housing, and a sound pressure adjustment mechanism. One end of the signal wire is electrically connected to the speaker. The speaker and part of the signal wire are fitted on the housing, whereas the other end of the signal wire extends outside the housing. The sound pressure adjustment mechanism is installed on the housing and equipped with at least one opening; the opening is reconfigured to adjust and/or completely closed.
It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed. Other advantages and features of the invention will be apparent from the following description, drawings and claims.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
The speaker 101 and part of the signal wire 103 are fitted on the housing 105. One end of the signal wire 103 is electrically connected to the speaker 101. The other end of the signal wire 103 extends outside the housing 105. The speaker 101 converts the electrical signal transmitted by the signal wire 103 into sound, thereafter the sound is sent to outside the housing 105.
In the first embodiment, the sound pressure adjustment mechanism 107 comprises a fixation disk 1071 and a knob 1073. A first opening 1071a and a corresponding second opening 1073a are disposed in the fixation disk 1071 and the knob 1073 respectively. The fixation disk 1071 is installed on the housing 105, whereas the knob 1073 is installed inside the housing 105 and pivoted to the fixation disk 1071. A protruding rod 1073b of the knob 1073 protruded out and moved along the first opening 1071a, thereby rotates the knob 1073 around the center of the fixation disk 1071, to alter the way in which the first opening 1071a overlaps the second opening 1073a. Consequently, the opening of the sound pressure adjustment mechanism 107 could be adjustable or completely closed.
