1. Field of the Invention
The present invention relates to a wireless headphone, especially to a wireless headphone with a self-actuated switch.
2. Description of the Prior Arts
A headphone is used on personal music devices such as a Walkman®, a CD-player, hi-fi equipment, etc. to transmit sound and in particular music, in a vividly stereophonic manner, whereby the user can enjoy loud music without disturbing others. A conventional headphone is connected to the appropriate device by an electric wire. However, the electric wire can be a nuisance in terms of restricting the user's movements while the headphone is connected to a large hi-fi device and so wireless headphones have become a popular alternative. Because the wireless headphone has no wire to connect to the broadcast equipment, the electric power is provided by batteries that are mounted in the wireless headphone. If the headphone is unintentionally left in a power on status but no music is being played, the user will be unaware of the power waste situation. This can ultimately be irritating because when someone wants to relax by listening to music with such headphones, it is a nuisance to then have to go out and buy replacement batteries. In order to avoid the waste of the batteries, the wireless headphone has a switch to control the electric connection. Nevertheless, it is found that on one hand the conventional switch has to be located in an easily accessible position but on the other hand such a location means the switch is easily actuated unintentionally, such as by putting down the headphones. To overcome the shortcoming, the present invention provides a wireless headphone with a self-actuated switch to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a wireless headphone with a self-actuated switch.
The wireless headphone with the self-actuated switch comprises a belt, two retainers and a self-actuated switch. The self-actuated switch has a base and a resilient bar. The base is mounted in a mounting recess in the belt and has a button. The resilient bar is mounted in the mounting recess in the belt and selectively presses against the button. Bending the belt will force the resilient bar to move forward. When the button is pressed, the wireless headphone will be actuated.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The base (13) is mounted in the mounting recess (12) and on the holding block (110) and has a proximal end, a distal end and a button (130). The proximal end connects to the holding block (110). The button (130) is formed on the distal end of the base (13). When the button is pressed, the wireless headphone will be actuated, as to be described in detail later.
The resilient bar (14) is mounted in the mounting recess (12), extends into the mounting recess (12), is optionally formed on the belt (11) and has a proximal end, a distal end and an optional contacting surface (140). The contacting surface (140) is formed on the distal end and selectively presses against the button (130) on the base (13).
With further reference to
The self-actuated switch on a wireless headphone as described makes a huge improvement. Whenever the user wears the wireless headphone, the switch will be self-actuated by the flexing of the belt (11). Because the switch is actuated only when the belt (11) is flexed, the switch will not be unintentionally actuated. Furthermore, when the headphone is removed and no longer required, the power consumption is automatically terminated. Hence, both situations automatically prevent prematurely exhausting the batteries.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
