TWI240590B - Handheld Dolby decoding earphone apparatus - Google Patents

Abstract

A handheld Dolby decoding earphone apparatus is composed of a Dolby decoder and at least one earphone. The Dolby decoder receives digital fiber optic audios inputted by external electronic products (such as digital video discs, compact discs, MP3 players, televisions, tuners, video compact discs, acoustics, various computers). The Dolby decoder converts the digital audios into phase time differences to generate Dolby surrounding sound. Fixing/external earphones are used to output the sound to a user for listening. Because the present invention reduces the size of the Dolby decoder to allow the user to carry so as to apply in various environments, the earphones could output the sound to avoid the sound to influence other persons.

Description

[Technical Field] The present invention relates to a handheld device, which is a device that reduces the Dolby decoder to be used in various environments and interferes with others through sound effects. -Type Dolby Decoding Headphone Device, in particular, allows users to take it with them and use the = headphone to output sound effects to avoid the trouble of palm-type Dolby Decoding Headphones [Previous Technology]

Various home theater combination sounds in the room are made by various DvD amplifiers. The Dolby decoder included in the host converts the sound source into Dolby sound and transmits it to each ϋ j. Multiple speakers are set up at fixed positions to generate multiple sounds. The first ratio: the effect is more effective for users to enjoy; but the above home theater = setting method has the following shortcomings and deficiencies: 1 # 1, the home theater audio combination system is set in a fixed position, the room or a specific Space and position to listen to, you ca n’t change it to enjoy Dolby sound. 2. When the home theater audio combination is used, the excessively large sound effect often interferes with family members or neighbors, so it is often restricted in use.

3. When the home theater audio combination is set, there are restrictions on the environmental area. Therefore, it often happens that there is not enough space to set up. 4. The setting of the sound combination of the Huating Theatre often costs a lot of money. 5. The home theater audio system is wired, so it is time-consuming and laborious in wiring. It can be seen that the above-mentioned conventional home theater audio combination setting method still has
