1. Field of the Invention
The present invention relates to an earphone device, and more particularly to an earphone device which can regulate sound quality based on regulating a cover connected with a regulating device and corresponding regulation method.
2. Description of Related Art
Refer to
The number of the pressure relief holes 12 in the housing 10 of the conventional earphone device is determined according to specific group of consumers, so the sound pressure in the inner cavity is a constant, which determines the frequency characteristic of the earphone device. However, since conventional earphone devices may be applied in connecting mobile phones for communication or in music players which may store hundreds of or thousands of songs, it needs different frequency characteristics to meet different kinds of sound quality requirements. The constant sound pressure in the inner cavity causes that the conventional earphone device can only be adapted for a special audio performance and users cannot regulate sound quality freely according to themselves. Hence, conventional earphone devices have the shortcoming of low variability, which needs to be overcome.
An object of the present invention is to provide an earphone device with a function of sound quality regulation.
To achieve the above-mentioned object, an earphone device with a function of sound quality regulation in accordance with the present invention is provided. The earphone device includes a housing, a cover, a speaker and a regulating device, wherein the housing has a plurality of regulating holes and the housing combines with the cover to form an accommodating space for receiving the speaker, and the accommodating space is connected to the outside by the regulating holes; one end of the regulating device is fixed on the cover; a blocking portion, which is disposed on the other end of the regulating device, can partially or completely block the regulating holes when the cover turns, thereby regulating the leakage from the accommodating space to the outside to achieve different output sound quality.
Additionally, another object of the present invention is to provide a method of regulating sound quality of an earphone device, wherein the earphone device includes a housing and a cover, and the housing has an accommodating space for receiving a speaker and a plurality of regulating holes for connecting the accommodating space to the outside and the cover is combined with a regulating device of which a blocking portion extends into the accommodating space, the method includes: turning the cover to drive the regulating device; and selectively blocking the regulating holes via the blocking portion of the regulating device, thereby changing leakage from the accommodating space to the outside.
In comparison with conventional technologies, the present invention has the advantages that the present invention can regulate the leakage between the sound wave resonant room inside the earphone device and the outside to achieve different output sound quality, so that users can regulate proper output sound quality freely on their own will, accordingly, the earphone device of the present invention has high variability and is more sufficient to meet users' requirements.
The following is to explain an earphone device with a function of sound quality regulation and regulating method thereof according to the preferred embodiments of the present invention in combination with related drawings.
Please refer to
Furthermore, one end of the housing 21 is cap-shaped, thereby forming the accommodating space 211, and an extended tube 213 is disposed on the other end of the housing 21. A signal line electrically connected to the speaker 23 extends through the extended tube 213.
In this embodiment, the regulating device 24 includes a blocking portion 241, a combined portion 242 and a protruding ring portion 244. The regulating device 24 engages with a trench 215 of the housing 21 (please refer to
It must be explained that, in this embodiment, the cover 22 is annular, and besides the trench 222, the cover 22 also has a supporting portion 221 formed on the inner annular face for supporting and fixing the speaker 23.
Please refer to
It is worthy to be mentioned that the earphone device 20 of the preferred embodiment of the present invention is an earplug earphone, however, the structure of the present invention may also be applied in a in-ear earphone, and the changes which need to be made when the structure is applied in a in-ear earphone will become readily apparent to those skilled in the art, so the description is omitted.
Finally, the present invention further provides a method of regulating sound quality of an earphone device. The earphone device, like the earphone device as shown in
As described above, the earphone device with a function of sound quality regulation of the present invention enables users to regulate the leakage between the resonant room of the earphone device and the outside by turning the cover to drive the regulating device to achieve different output sound quality. Thereby, users can regulate proper output sound quality freely on their own will. Comparing with conventional earphone devices, the earphone device of the present invention has high variability and is more sufficient to meet users' requirements.
What are disclosed above are only the exemplary embodiments of the present invention and it is therefore not intended that the present invention be limited to the particular embodiments disclosed. It will be understood by those skilled in the art that various equivalent changes may be made depending on the specification and the drawings of the present invention without departing from the scope of the present invention.
