DETAILED DESCRIPTION OF THE INVENTION
[0017] The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
[0018] Referring to Fig. 1, a pen-type computer 1 in accordance with an embodiment of the invention includes a pen barrel 11 and a clip 13 hinged to the pen barrel 11. A sensor 112, a primary processor 113, a storage device 114, and a battery 115 are disposed in the pen barrel 11, wherein the battery 115 supplies power to all of the components 112, 113 and 114 in the pen barrel 11.
[0019] Referring to Fig. 2, the clip 13 includes a first part 131, an elongated second part 132, and an elongated third part 133. The first part 131 is hinged to the pen barrel 11. The first part 131 and the second part 132 are detachably connected via connectors (e.g. universal serial bus, USB) 1311 and 1328. The third part 133 is hinged to the second part 132. A battery 1324, a digital signal processor (DSP) 1325, an analog-to-digital converter 1326, and array microphones 1327 are disposed in the second part 132, while a sound-generating device 1331, a digital-to-analog converter 1332, and a transceiver 1333 are disposed in the third part 133.
The battery 1324 in the second part 132 supplies power to all of the components 1325, 1326, 1327, 1331, 1332 and 1333 in the clip 13. It is noted that the array microphones 1327 are longitudinally arranged along the clip 13.
[0020] Referring to Figs. 1 and 3, in a writing operation, a user grips the pen barrel 11 of the pen-type computer 1 and writes words on a surface (e.g. desk surface). The sensor 112 senses the movement of the writing tip 111 of the pen barrel 11 and generates a tracking signal corresponding to the movement of the writing tip 111. The primary processor 113 encodes the tracking signal into data (e.g. text-type data) and stores the data in the storage device 114. [0021] Referring to Figs. 3 and 4, in a sound-recording operation, the user rotates the clip 13 and directs the array microphones 1327 to a target sound source 2. The array microphones 1327 receive sound from the target sound source 2 and generate an analog electrical signal. The analog-to-digital converter 1326 converts the analog electrical signal into a first digital signal. The digital signal processor (DSP) 1325 processes the first digital signal for the purposes including beamforming, echo cancellation, noise suppression etc., and obtains a second digital signal. The primary processor 113 processes the second digital signal for the purposes including voice recognition and data compression to obtain data (e.g. audio data), and stores the data in the storage device 114.
[0022] Referring to Figs. 1 and 3, in a sound-playing operation, the primary processor 113 decompresses the data in the storage device 114 to obtain a digital signal. The digital-to- analog converter 1332 converts the digital signal into an analog signal. Then, the sound- generating device 1331 serves as a loudspeaker, turning the analog signal into sound. [0023] The data in the storage device 114 can be sent to an external device 3 (e.g. portable computer, personal digital assistant, cellular phone, etc.) via the transceiver 1333.
Furthermore, data in the external device 3 can be sent to the pen-type computer 1 via the transceiver 1333 and stored in the storage device 114.
[0024] Referring to Figs. 2 and 5, the second and third parts 132 and 133 can be detached from the first part 131 which is hinged to the pen barrel 11, and then worn over a user's ear to serve as an earphone. Also referring to Fig. 6, during a use of the earphone, the transceiver 1333 receives a digital sound signal from the external device 3. The digital-to-analog converter 1332 converts the digital sound signal into an analog signal. Then, the sound- generating device 1331 turns the analog signal into sound. When the user speaks, the array microphones 1327 receive the voice and generate an analog electrical signal. The analog-to- digital converter 1326 converts the analog electrical signal into a first digital signal. The digital signal processor (DSP) 1325 processes the first digital signal for the purposes including beamforming, echo cancellation, noise suppression etc., and obtains a second digital signal. Then, the transceiver 1333 sends out the second digital signal to the external device 3. [0025] In an exemplary embodiment of the invention, the earphone is a wireless-bluetooth earphone and the transceiver 1333 is a bluetooth transceiver.
[0026] Referring to Fig. 7, a pen-type computer 2 in accordance with another embodiment of the invention includes a pen barrel 21 and a pen cap 23 attached to the pen barrel 21. [0027] The pen barrel 21, similar to that of the previous embodiment, has a sensor 212 sensing the movement of the writing tip, a primary processor 213 encoding the tracking signal into data, and a storage device 214 storing the data. In this embodiment, the pen barrel 21 further includes a unidirectional sound-generating device 215 (e.g. array speakers). In operation, the user directs the unidirectional sound-generating device 215 to a person. Then, only the person can hear the sound from the sound-generating device 215.
[0028] The pen cap 23 has a cap body 236, a clip 237 extending from the cap body 236, a flexible portion 235 extending from the cap body 236, and an earphone 231 connected to the flexible portion 235 via connectors 234 (e.g. universal serial bus, USB).
[0029] The earphone 231 has array microphones 232 and a transceiver 233 inside. In a sound-recording operation, the user directs the array microphones 232 to a target sound source and records the sound in the storage device 214 of the pen barrel 21.
[0030] Referring to Fig. 8, the earphone 231 can be detached from the flexible portion 235 of the pen cap 23 and put in a user's ear. Then, the earphone 231 receives a sound signal from an external device via the transceiver 233.
[0031] In an exemplary embodiment of the invention, the earphone 231 is a wireless- bluetooth earphone and the transceiver 233 is a bluetooth transceiver.
[0032] While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
