Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1-2, an active speaker structure includes a housing 1, an audio input port and an audio input line 2, the audio input port is disposed on a surface of the housing 1, the audio input port includes an analog input interface 11 and a digital input interface 12, an analog signal conductor 21 and a digital signal conductor 22 are integrated with a body of the audio input line 2, an analog output connector 24 and a digital output connector 25 are integrated with a connection end 23 of the audio input line 2, the analog output connector 24 is used for being connected with the analog input interface 11, the digital output connector 25 is used for being connected with the digital input interface 12, and ends of the analog signal conductor 21 and the digital signal conductor 22 are respectively connected to the analog output connector 24 and the digital output connector 25.

The wire of the wire body is combined by using the existing analog signal wire 21 and digital signal wire 22, and the input joint of the connecting end connected with the audio equipment also adopts the standard joint of the existing analog signal wire 21 and digital signal wire 22.

The output connector of the connecting terminal 23 connected to the box 1 may be the standard connector of the existing analog signal wire 21 and digital signal wire 22, or may be the non-standard connector designed by the manufacturer. If the output connector of the audio input line 2 adopts a standard connector, the audio input port of the box body 1 also adopts an existing standard connector, and the output connector of the audio input line 2 adopts a non-standard connector, the audio input port of the box body 1 should correspond to the output connector of the audio input line 2. The advantage of using a standard connector is that it can also be mated with existing audio conductors, but the connector 23 can be bulky and the advantage of using a non-standard connector is that the manufacturer can control the shape of the connector 23. If allowed, the non-standard connector and the non-standard interface can be matched, and the standard interface is arranged on the box body 1 for standby. The three forms are selected and used by manufacturers according to actual conditions.

By adopting the structure, the active sound box structure enables the audio input line 2 to be capable of conducting both analog audio signals and digital audio signals, when the sound box selects analog signal connection, the analog output connector 24 of the audio input line 2 is plugged on the analog input interface 11 of the box body 1, and when the sound box selects digital signal connection, the digital output connector 25 of the audio input line 2 is plugged on the digital input interface 12 of the box body 1. The spare wire which is not connected currently can be kept on site and is not damaged accidentally.

If the active sound box structure adopts the forms of the standard connector and the standard interface, because the supporting structure of the connection point of the audio input line 2 inserted in the audio input port is possibly unbalanced and is easy to incline downwards, the supporting blocks 13 can be arranged at the lower side positions of the analog input interface 11 and the digital input interface 12, the connecting end 23 is supported by the supporting blocks 13, and the stress balance is ensured. Preferably, the upper side of the supporting block 13 is formed in an arc-shaped concave shape to be attached to the connecting end 23.

In addition, as shown in fig. 3-4, a rotary cover 26 may be provided at the end of the connection terminal 23 of the audio input line 2, the rotary cover 26 has an opening 27, the rotary cover 26 covers the analog output connector 24 and the digital output connector 25, when one connector is used, the opening 27 is rotated to one side of the connector so that the connector can be plugged with the interface, and the other connector is covered by the rotary cover 26 to form a dustproof structure, which ensures that the best state is maintained when the connector is in standby.

In order to avoid the possibility of signal interference due to the distance between the analog signal line 21 and the digital signal line 22 being too close, a shielding layer 28 may be provided on the outer sides of the analog signal line 21 and the digital signal line 22.

The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
