## Background
FIELD
The subject matter herein generally relates to the field of connectors and electronic device, and more particularly to a connector and an electronic device system using the same.
BACKGROUND
At present, handheld electronic products, such as tablets, mobile phones, etc., have been widely used in people's daily lives. The handheld electronic products need to be thin and easy to manufacture to meet market demand. An accessory of the handheld electronic product usually sets a dock to expand its additional functions (such as high-power speakers, charging, etc.) to increase the value of the handheld electronic product.
When the appearance of the handheld electronic product changes, the connecting structure connecting the handheld electronic product to the accessories, such as a tablet and a dock, will be changed too. It is necessary to add a suitable limit structure and a suitable guide structure on the tablet computer or the dock to prevent the dock from crashing at the moment the tablet is inserted into the dock. The service life of the tablet and the dock can be reduced because of the crash. If the dock has a speaker, the dock can generate a transient noise at the moment the tablet is inserted into the dock, and the transient noise makes the user feel uncomfortable.

Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “inside” indicates that at least a portion of a region is partially contained within a boundary formed by the object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The working process of the electronic device system 200 is described with reference to FIGS. 1-10.
In operation, firstly, a power supply interface (not shown) of the of the interface assembly 213 is connected with an external power source through a cable (not shown), and the first electronic device 210 is connected to the external power source. Secondly, the protruding portion 225 of the second electronic device 220 aims at the plug recess 125 of the first electronic device 210, and the second electronic device 220 is placed on the placing groove 124. The second electronic device 220 is smoothly placed on the first electronic device 210 by the engagement of the protruding portion 225 and the plug recess 125, and the second connecting unit 130 is located over the inserted hole 121. Thereafter, the second magnetic bodies 131 mounted on the second connecting unit 130 attracts the first magnetic bodies 111 mounted on the first connecting unit 110. With the engagement of the guide holes 115 and the guide columns 122, the first connecting unit 110 moves from the bottom of the socket portion 141 of the connecting structure 140 to the screw portion 142 and moves smoothly toward the second connecting unit 130. Finally, the first connecting unit 110 contacts with the second connecting unit 130. The first conductive units 116 and the second conductive unit 117 of the first conductive assembly 118 is electrically connected with the third conductive units 135 of the second conductive assembly 137. The first connecting unit 110 is electrically connected with the second connecting unit 130, and the first electronic device 210 is electrically connected with the second electronic device 220 so that the first electronic device 210 charges the second electronic device 220.
When the second electronic device 220 is not placed on the first electronic device 210, the first conductive assembly 118 and the first body 112 of the first connecting unit 110 are not exposed from the inserted hole 121 of the placing groove 124. The first conductive assembly 118 and the first body 112 are buckled at the bottom of the socket 141 of the connecting structure 140, and the first body 112 has a distance from the threaded portion 142 of the connecting structure 140. The distance is an active stroke of the first connecting unit 110, and the distance can be adjusted by adjusting the engagement length of the connecting structure 140 and the second fixing portion 123.
After the second electronic device 220 is placed on the first electronic device 210, the first conductive assembly 118 extends slowly from the inserted hole 121 and is electrically connected with the second conductive member 137. In this way, the first conductive assembly 118 and the second conductive assembly 137 are prevented from colliding during the working process. In addition, since the guide column 122 has a tapered shape and an inner wall of the guide hole 115 has an outer convex arc, and the first connecting unit 110 can slid smoothly on the supporting member 120 by the engagement of the guide hole 115 and the guide column 122.
An audio device will produce a blasting sound at the moment the audio device is power-off or power-up. After the audio device is powered on, the operation of the audio device will also produce the blasting sound. The blasting sound is a transient noise. The audio device includes a power amplifier chip, and the power amplifier chip has a mute pin and a power supply pin. If the mute pin connects to power supply first, the power supply pin connects to power supply after a short time, and the audio will not produce the transient noise. The short time is not less than 200 us.
It should be noted that, the length of the second conductive unit 117 is shorter than the length of the first conductive unit 116. Therefore, the first conductive units 116 is electrically contacted with the third conductive units 135 first when the connecting unit 110 moves toward to the second connecting unit 130, and the second conductive unit 117 is electrically contacted with one of the third conductive units 135 after a short period of time. The short period of time is not less than 200 us. The difference between the lengths of the first conductive unit 116 and the second conductive unit 117 is 0.02 mm to 0.32 mm.
In the embodiment, the first electronic device 210 has a speaker and a power amplifier chip connected to the speaker (not shown). The power amplifier chip has a mute pin and a power supply pin (not shown). The mute pin connects to the first conductive unit 116, and the power supply pin connects to the second conductive unit 117. The second conductive unit 117 is electrically connected with a outer power. When the second electronic device 220 is inserted into the first electronic device 210, the first conductive unit 116 contacts a third conductive unit 135 first, and the mute pin of the power amplifier chip is enabled to cause the power amplifier chip to be muted. After a short period of time, the second conductive unit 117 contacts the third conductive unit 135. The power supply pin of the power amplifier chip is electrically connected with the outer power, and the power amplifier chip and the speaker begin to work. As the power amplifier chip has been muted that can not output sound, so that the speaker does not generate a transient noise, and the purpose of eliminating the transient noise is achieved.
The connector 100 and the electronic device system 200 with the connector 100 are provided with a freely movable first connecting unit 110. When the second connecting unit 130 is placed on the first connecting unit 110, the first connecting unit 110 is smoothly adsorbed and electrically connected to the second connecting unit 130. Thereby, the second electronic device 220 is electrically connected with the first electronic device 210. There is no external force in the connection of the first connecting unit 110 and the second connecting unit 130, and the first connecting unit 110 and the second connecting unit 130 do not impact each other by the external force. The connector 100 and the electronic device system 200 are simple and useful. The connector 100 and the electronic device system 200 eliminate the transient noise generated when the first connecting unit 110 is electrically connected to the second connecting unit 130 by providing the first conductive member 116 and the second conductive member 117 of different lengths. The design of the first conductive member 116 and the second conductive member 117 is novel, and the effect of eliminate transient noise is good.
