Description

The present invention relates to a vehicle door trim.

Conventionally, as a vehicle door trim, one having a speaker grill is known (see Patent Document 1 below). In Patent Document 1, a speaker is arranged on the outside of the vehicle chamber of the door trim. The speaker is provided so as to face the vehicle interior side, and the speaker grill is provided so as to cover the speaker from the vehicle interior side.

Japanese Unexamined Patent Publication No. 2018-144753

In the above configuration, the speaker is provided so as to face the vehicle interior side. However, since the occupant's ears are arranged so as to face the front of the vehicle, it may be difficult for the sound output from the speaker to be directly transmitted to the occupant. In this case, the occupant needs to take measures such as increasing the volume of the sound output from the speaker, and there is room for improvement in this respect.

The technology disclosed in the present specification has been completed based on the above circumstances, and provides a vehicle door trim capable of reliably transmitting the sound output from the speaker to the ears of the occupant. With the goal.

As a means for solving the above problems, the vehicle door trim disclosed in the present specification includes a plate-shaped trim main body, a speaker arranged outside the vehicle chamber of the trim main body, and the trim main body. The trim body is provided with a housing member arranged outside the vehicle chamber and accommodating the speaker, which has a long box shape in the front-rear direction of the vehicle and has an opening opened at the rear of the vehicle. The portion is characterized in that it has a through hole that overlaps the opening from the rear of the vehicle.

The sound output from the speaker goes into the vehicle room through the opening and the through hole. Since the opening is opened to the rear of the vehicle and the through hole overlaps the opening from the rear of the vehicle, the sound toward the vehicle interior through the opening and the through hole is directed to the rear of the vehicle. Generally, the seated occupant's ears are arranged behind the vehicle door trim (or near the rear end) so as to face the front of the vehicle, so that the speaker is arranged in front of the occupant's vehicle. By outputting the sound from the speaker in front of the occupant toward the rear of the vehicle, the sound output from the speaker can be reliably transmitted to the ears of the occupant.

Further, since the speaker is housed in the housing member, the sound output from the speaker can be reliably transmitted to the opening and thus to the through hole. In a configuration without a housing member, the speaker must be arranged adjacent to the through hole in order to ensure that the sound from the speaker is directed to the through hole. In this case, the speaker grill covering the through hole is provided. By providing the speaker, it is preferable to prevent the occupant from touching the speaker through the through hole. However, if the speaker grill is provided, the speaker grill hinders the transmission of sound, and there is a concern that the quality of the sound output from the speaker deteriorates. On the other hand, in the above configuration, since the speaker is housed in the accommodating member, the sound from the speaker can be reliably transmitted to the opening and thus to the through hole while ensuring the distance between the speaker and the opening. As a result, the distance between the speaker and the through hole can be secured, and the speaker grill covering the through hole can be eliminated, so that the quality of the sound output from the speaker can be further improved.

In the above configuration, the speaker may be configured to be capable of outputting sound toward the rear of the vehicle. By outputting the sound from the speaker toward the rear of the vehicle, the sound output from the speaker can be reliably transmitted to the ears of the occupant.

Further, the trim main body portion may include an upper board constituting the upper end portion of the trim main body portion, and the accommodating member may be arranged outside the vehicle chamber of the upper board. Since the accommodating member and thus the speaker can be arranged at a higher position, the sound output from the speaker can be reliably transmitted to the ears of the occupant.

Further, the speaker may be arranged at a position closer to the front side of the vehicle in the internal space of the accommodating member. As a result, it is possible to more reliably suppress the situation where the occupant touches the speaker through the through hole and the opening.

Further, the armrest provided on the trim main body and the switch base provided on the armrest are provided, and the accommodating member is arranged at a position higher than the switch base and with respect to the switch base. It can be located in front of the vehicle. By arranging the accommodating member in front of the vehicle from the switch base, the speaker can be more reliably arranged in front of the vehicle with respect to the ears of the occupant, which is generally located behind the switch base.

Further, the trim main body portion is provided with a groove portion that opens to the vehicle interior side, and the groove portion extends in an ascending manner toward the rear of the vehicle, and the groove portion extends behind the vehicle with respect to the through hole. It can be arranged at the front end of the vehicle and communicated with the through hole. Most of the sound output from the speaker goes into the groove through the through hole. Since the groove portion extends in an ascending and inclined manner toward the rear of the vehicle, the sound reaching the groove portion from the through hole tends to be directed toward the rear and upward of the vehicle. As a result, the sound can be easily directed to the ears of the occupant at a position higher than the vehicle door trim.

According to the present invention, it is possible to provide a vehicle door trim capable of reliably transmitting the sound output from the speaker to the ears of the occupant.
