2. Description of Related Art
With the continuous progress in technology, all electronic products have been developed towards light, handy and miniaturized designs. For the sake of conveniently listening to sound information provided by electronic products without disturbing other people around, people may use miniaturized electronic products, such that an earphone has become a necessary accessory to the electronic product. Moreover, the earphone also provides a listener with better audio transmission so that the listener can clearly hear and understand content of the audio information. In contrast to unclear audio transmission through the air, especially when the listener is moving, for example like doing exercises, driving, intensely moving around or being in a noisy environment, the audio transmission of the earphone still would not be affected.
The invention provides an earphone which can resolve an issue that a convention earphone is incapable of light-emitting.
The invention is directed to an earphone including an earphone body, a photosensitive switch, a power supplier and a light emitter. The photosensitive switch, the power supplier and the light emitter are disposed on the earphone body. The light emitter is electrically connected to power supplier through the photosensitive switch.
In an embodiment of the invention, the earphone further includes a manual switch, where the photosensitive switch is electrically connected to the power supplier through the manual switch.
In an embodiment of the invention, the earphone further includes a manual switch, where the light emitter is electrically connected to the power supplier through the manual switch.
In an embodiment of the invention, the light emitter is an electroluminescent element or a light-emitting diode (LED).
In an embodiment of the invention, the earphone body includes two earcup bodies and a strap. Two ends of the strap are connected with the two earcup bodies, and the light emitter is disposed on at least one of the two earcup bodies and the strap.
In an embodiment of the invention, sensitivity of the photosensitive switch is adjustable.
To sum up, the earphone of the invention has the light emitter capable of decorating or warning.
In order to make the aforementioned and other features and advantages of the invention more comprehensible, several embodiments accompanied with figures are described in detail below.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
The light emitter 140 is electrically connected to power supplier 130 through the photosensitive switch 120. In a scenario where luminance of external light sensed by the photosensitive switch 120 is sufficient, the photosensitive switch 120 keeps the light emitter 140 being disconnected from the power supplier 130. Thus, the light emitter 140 is incapable of obtaining power supplied by the power supplier 130 and does not emit light. In a scenario where the luminance of the external light sensed by the photosensitive switch 120 is insufficient, the photosensitive switch 120 induces conduction between the light emitter 140 and the power supplier 130. Thus, the light emitter 140 can obtain the power supplied by the power supplier 130 to emit light. In this way, the light emitter 140 on the earphone body 110 can emit light or be turned off automatically according to the change of the ambient luminance, so as to not only provide the user of the earphone 100 with caution light for safety, but also to be used for the appearance style of the user.
In the present embodiment, the light emitter 130 may be an electroluminescent element or a light emitting diode (LED), the power supplier 130 may be a battery storing electricity, a solar cell or an element obtaining power from a player connected with the earphone 100. Sensitivity of the photosensitive switch 120 is adjustable, so as to conform to usages of different users. Additionally, when emitting the light, the light emitter 130 may continuously light or intermittently light, regularly or irregularly, with changeable luminance. The light emitter 130 brings a warning or decorating effect. Moreover, the light emitter 130 may be designed to light with the rhythm of music being played by the earphone 100. The aforementioned lighting modes can be achieved only by the use of a common controller, and thus, description regarding the controller is omitted herein.
In the present embodiment, the earphone 400 is a wired circumaural type, for example, but the earphone of the invention may by other types and causes no affection to the usage of the earphone of the invention that the photosensitive switch and the light emitter are employed for decoration and warning functions.
In view of the foregoing, the earphone of the invention is equipped with the photosensitive switch and the light emitter, such that the photosensitive switch can activate the light emitter to provide variations of light. Thereby, the earphone can provide not only variety for the style of the user, but also a warning function by employing the light provided from the light emitter, such that personal security of the user can be protected.
Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
