Problems solved by technology

[0004] However, even the headphones with the same resistance value produced by the same manufacturer have different models / types, and the sound effects of different models / types of headphones are different. For example, the headphones produced by Y manufacturer with a resistance value of 32 ohms are A, B, etc. Models / types, where A model / type earphones have better midrange effects, poorer bass effects, and mediocre treble, while B model / type earphones have better bass effects, mediocre midrange, and poor treble
In the U.S. patent with the publication number 20050201568, it only disclosed that the output power is adjusted according to the resistance value of different earphones, so that when using A or B type / type earphones, the audio playback device will output the corresponding power of 32 ohm earphones. The result is that the audio sound effect that the user hears will not be ideal

Embodiment Construction

[0016] see figure 1 , is a schematic diagram of the earphone plug of the earphone included in the audio playback device of the present invention. The earphone plug 101 includes an audio ground pin Audio GND, an identification pin ID, a left channel pin L, and a right channel pin R. The pins are separated by insulating material.

[0017] Please also refer to figure 2 , is a schematic diagram of the connection relationship between the headphone impedance and the plug pin. The identification pin is connected to an identification resistor R ID (hereinafter referred to as "R ID ”). The left and right channel impedances of the earphone body are R L , R R . The identification resistor R ID and headphone left and right channel impedance R L , R R Connect in parallel to the audio ground pin.

[0018] see image 3 , Figure 4 and Figure 5 , image 3 It is a schematic diagram of the combined use of the earphone and the earphone jack of the present invention. Figure 4 I...

Abstract

The invention provides an earphone and an audio play device which is used for identifying the earphone type and adjusting a playing sound effect mode. The earphone includes a ID pin and a ID pin grounding resistance RID.Furthermore, the invention provides an audio play device which is used for identifying the earphone type and adjusting the playing sound effect mode. The audio play device includes an audio jack, an audio play unit, a micro processor, a memory, an analog-to-digital converter and a detecting unit. The audio play device identifies the earphone type by detecting a resistance value of the ID pin grounding resistance RID, and adjusts the playing sound effect mode according to the earphone type to obtain a suitable sound effect.

Description

technical field [0001] The invention relates to an earphone and an audio playback device for identifying the type of the earphone and adjusting the sound effect mode. Background technique [0002] Generally speaking, the sound effect output by an audio playback device is fixed, and the earphone becomes an important accessory that affects the sound effect. The audio quality output from the playback device is still not very good. Therefore, in order to ensure that users can hear better sound effects, manufacturers of audio playback devices match each audio playback device with an earphone. But often a user often has multiple different types / models of headphones, for example, some users are not used to earbuds but are used to earmuffs, or users want to use different types / models of headphones in some cases, or the matching After the headset is damaged, the user needs to purchase a new matching headset. [0003] There are many manufacturers of earphones in the market now, and...
