A headphone has a shell, a speaker received in the shell for making sound, a covering element fixed on the shell. A top of the shell is recessed to form a receiving cavity. A damping plate is received in the receiving cavity for separating the receiving cavity and the resonance cavity. The damping plate smoothes the frequency response of the sound pressure level in the resonance cavity while the speaker making sound, which adjusts the sound and achieves a better sound effect. It is convenient to change the damping plate. As the damping plates made of different materials have the different sound effects, users can change the damping plate for changing the sound effect. So, the user can enjoy different sound effects by only changing the damping plate.

A headset includes a housing having a first wall with at least one sound hole formed thereon, a loudspeaker unit disposed in the housing and adjacent to the sound hole, a blocking component mounted in the housing and capable of slidably moving towards and backwards the first wall to form an adjunctive chamber therebetween, and an adjustive component rotatably mounted to the housing. The adjustive component is connected with the blocking component in a way of screw link in order to drive the blocking component to move towards and backwards the first wall when the adjustive component is driven to rotate.

A prompting device for an optical finger navigation sensor, a prompting method thereof, and a prompting system are provided. The prompting device includes at least one light-emitting unit, which is disposed around the OFN sensor. The prompting device is integrated with the OFN sensor. According to the finger position transmitted back to the operating system from the OFN sensor and the action that the operation system can do accordingly, the light-emitting unit provides a blue or green optical indication for the user to perform the next action. Or when the operation system performs the action needed to prompt, the prompting device can prompt the user for the next action. Therefore, the optical indication of the present invention can prompt the user to perform the action, thereby providing a convenience for the user.

Provided is an adjustable audio headphone, including a headphone body, a damping object and a pressing mechanism. The headphone body includes a headphone shell, which forms a sound cavity in inside thereof and a receiving chamber on one end thereof. A bottom surface of the receiving chamber forms a through hole communicated with the sound cavity. The damping object is made of compressible material such as sponge, elastic plastic, textile and so on and. The damping object is placed into the receiving chamber of the headphone shell. The pressing mechanism is mounted on the headphone shell and is capable of pressing the damping object. The adjustable audio headphone of the present invention can compress the damping object to change the density of the damping object by employing the pressing mechanism, thereby varying the pressure of the sound cavity and realizing the object of adjusting the audio thereof.

A laser projector has a cursor control unit, a main control unit, a laser generator and a scanning lens. The cursor control unit is used to generate and transmit cursor signals; the main control unit is used to obtain and process video signals and the cursor signals, both of which are combined into cursor video signals and transmitted; the laser generator is coupled to the main control unit for generating and projecting laser beam according to the cursor video signals; and the scanning lens is coupled to the main control unit for receiving the laser beam and projecting it outward in a predetermined scanning manner. The laser projector of the present invention uses laser resource itself to project laser cursor generated by the cursor control unit onto a screen, so that it is unnecessary to additionally use a laser pointer, and the operation of the laser projector is relatively simple.

An in-ear headphone has a shell, a loudspeaker accommodated in a space of the shell for making sound, an ear cushion fixed on a supporting portion of the shell. A through channel passes the whole supporting portion for connecting the space with outside to transmit the sound produced by the loudspeaker. The ear cushion has a through hole passing through the whole ear cushion. A top of the through hole is enlarged to form a first receiving cavity for receiving a first damper. The first damper can seal against the outside region preventing the particles into the in-ear headphone and damaging the loudspeaker. Also, the first damper adjusts the sound effect of the in-ear headphone. Moreover, the first damper can be taken off the first receiving cavity easily and replaced by another one. So, the user can experience varies sound effect by changing the first damper.
