CN202711687U - Sound source management device of vehicle-mounted system - Google Patents

Abstract

The utility model discloses a sound source management device of a vehicle-mounted system. The sound source management device comprises: a plurality of vehicle-mounted application devices; an audio analysis module for performing analysis on the audio played by each of the vehicle-mounted application devices to determine whether the current audio is played by the last started vehicle-mounted application device; an audio output module for connecting the audio analysis module; and a vehicle-mounted controller for causing the current audio to be played and outputted through the audio output module when the audio analysis module determines that the current audio is played by the last started vehicle-mounted application device, wherein the vehicle-mounted controller is connected with each vehicle-mounted application device and the audio analysis module separately. According to the utility model, the audio played by the lasted started vehicle-mounted application device is outputted and played by the audio output module, so that the disadvantage of sound mixing can be effectively eliminated. According to the utility model, advantages of simple structure and low implementation cost are realized.

Description

The source of sound management devices of onboard system

Technical field

The utility model relates to a kind of mobile unit, especially relates to a kind of source of sound management devices of onboard system.

Background technology

Existing onboard system has the vehicular applications device of multiple AF playing function, each vehicular applications device is play the audio frequency of different sources of sound, plays suggestion voice, the multimedia player of car backing operation such as radio broadcasting program broadcast signal, radar for backing car and plays the multimedia file from CD, VCD even USB.But when multiple vehicular applications device was in the use state simultaneously, the sound of different sources of sound was play together and will everybody do not heard, from having formed noise, audio mixing.So just bring very large trouble to the user, can not allow the user listen him to want the sound of listening.

The utility model content

The utility model proposes a kind of source of sound management devices of onboard system, do not produce audio mixing when multiple vehicular applications device is used simultaneously, improve the user experience of onboard system.

The utility model adopts following technical scheme to realize: a kind of source of sound management devices of onboard system, and it comprises:

A plurality of vehicular applications devices;

Be used for the audio frequency that each described vehicular applications device is play is analyzed, determine the audio analysis module that described vehicular applications device is play whether current audio frequency starts at last;

The audio frequency output module that connects described audio analysis module;

Be used for determining that in described audio analysis module current audio frequency is that a last described vehicular applications device that starts is when playing, control is play the Vehicle Controller of output with current audio frequency by described audio frequency output module, and described Vehicle Controller connects respectively each described vehicular applications device and described audio analysis module.

Compared with prior art, the utlity model has following beneficial effect:

The source of sound management devices of the onboard system that the utility model proposes when opening a plurality of vehicular applications devices audio plays is arranged, makes the vehicular applications device audio plays opened at last from the output of audio frequency output module and plays, thereby can effectively eliminate audio mixing.The utlity model has simple in structure and the lower-cost advantage of realization.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, the utility model proposes a kind of source of sound management devices of onboard system, do not produce audio mixing when multiple vehicular applications device is used simultaneously, improve the user experience of onboard system.Specifically, the utility model comprises: the Vehicle Controller 11 that adopts embedded system (such as Android operating system); A plurality of vehicular applications devices 12 that connect respectively Vehicle Controller 11; Be used for the audio frequency that each vehicular applications device 12 is play is analyzed, determine the audio analysis module 13 that a vehicular applications device 12 that whether current audio frequency starts is at last play, this audio analysis module 13 connects described Vehicle Controller 11; The audio frequency output module 14 that connects described audio analysis module 13 is used for output sound signal.

When a plurality of vehicular applications device 12 work, by the reproduction time beginning and ending time of audio analysis module 13 each vehicular applications device 12 audio plays of record, judge whether current audio frequency is the audio frequency of nearest (or last) broadcast, if then Vehicle Controller 11 controls are exported current audio frequency by audio frequency output module 14.

To sum up, the source of sound management devices of the onboard system that the utility model proposes, when opening a plurality of vehicular applications devices 12 audio plays is arranged, make audio frequency that a vehicular applications device 12 of last startup plays from 14 outputs of audio frequency output module and play, thereby can effectively eliminate audio mixing.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims (1)

1. the source of sound management devices of an onboard system is characterized in that, described device comprises:

A plurality of vehicular applications devices;

Be used for the audio frequency that each described vehicular applications device is play is analyzed, determine the audio analysis module that described vehicular applications device is play whether current audio frequency starts at last;

The audio frequency output module that connects described audio analysis module;

Be used for determining that in described audio analysis module current audio frequency is that a last described vehicular applications device that starts is when playing, control is play the Vehicle Controller of output with current audio frequency by described audio frequency output module, and described Vehicle Controller connects respectively each described vehicular applications device and described audio analysis module.
