Abstract
The utility model relates to an automatic power-on MP3 player, which mainly consists of an MP3 player body (1) and a headphone jack seat (2). The automatic power-on MP3 player is characterized in that the inner wall of the headphone jack seat (2) is provided with a power anode connection contact plate (21), a power cathode connection contact plate (22) and an audio frequency connection contact plate (23); one end of the power anode connection contact plate (21) is welded at the anode of a circuit (11) on the circuit board of the MP3 player body (1); one end of the power cathode connection contact plate (22) is welded at the cathode of the circuit (11) on the circuit board of the MP3 player body (1); one end of the audio frequency connection contact plate (23) is connected with the audio frequency circuit of the circuit (11) on the circuit board of the MP3 player body (1) through welding; and when a headphone plug (3) is inserted in the headphone jack seat (2), the MP3 player can be automatically powered on. The utility model has the advantages of simple structure, capability of satisfying individual needs of people, and good market prospects.
Description
Technical field
The utility model relates to the MP3 player, the just Auto Power On MP3 player of Auto Power On when especially a kind of headset plug inserts the earphone jack seat of MP3 player.
Background technology
Progress along with society, the development of modern industry, all kinds of MP3 are ubiquitous in people's work, living and studying, for people's walkman music is brought unlimited convenience, enjoyed unlimited music enjoyment, but existing MP3 player all is after inserting headset plug, needs by the start button, just can enter into the state of playing back music, can not satisfy the needs of people's individual character.
Summary of the invention
The purpose of this utility model is a kind of addressing the above problem of development, and is simple in structure, when headset plug inserts the earphone jack seat of MP3 player, and the just Auto Power On MP3 player of Auto Power On.
The utility model is achieved through the following technical solutions:
The utility model mainly is made up of MP3 player main body and earphone jack seat, it is characterized in that: earphone jack seat inwall is provided with positive source and connects contact, power cathode connects contact and audio frequency is connected contact, positive source is connected the positive pole that contact one end is welded on the board circuit of MP3 player main body, power cathode is connected the negative pole that contact one end is welded on the board circuit of MP3 player main body, audio frequency is connected the voicefrequency circuit welding of the board circuit of contact one end and MP3 player main body and is connected, when headset plug inserts the earphone jack seat, anodal contact and the power cathode connection contact connected of becket energized on the headset plug, thereby connect the positive pole and the negative pole of circuit, board circuit forms path, realize Auto Power On, when further inserting, audio frequency connects contact and headset plug is connected, when headset plug is extracted the earphone jack seat, the positive pole of board circuit and negative pole disconnect, and realize shutdown automatically, reach purpose of design.
This reality is novel to have following advantage:
1, via enforcement of the present utility model, simple in structure, water resistance is good.
