Problems solved by technology

[0006] However, for the headrest device, there is a standard that the impact when the occupant's head is pressed against the headrest must be below a predetermined value. If a microphone as an audio device is installed near the front surface of the headrest, it will be difficult to meet the above standards because the audio device will hit the head and cause impact.

[0046] figure 1 and figure 2 It is a perspective view showing the headrest device 10 according to the first embodiment of the present invention. figure 1 The illustration of the back cushion core material 12 mentioned later is abbreviate|omitted. figure 2 The illustration of the front surface of the back cushion 13 mentioned later is abbreviate|omitted.

[0047] The headrest device 10 is installed on a passenger seat disposed in the vehicle interior. Examples of the vehicle compartment include those of automobiles, trains, airplanes, ships, and the like. In the first embodiment, however, a headrest device provided on a front seat of an automobile, that is, a seat on which a driver sits is used. 10 is described as an example. As an automobile, in addition to a normal four-wheeled vehicle, for example, a small electric vehicle which does not have a side door can be mentioned.

[0048] The seat (not shown) includes a seat surface portion (not shown) on which a driver (seat...

Abstract

The headrest device of the present invention can satisfy the impact standard, and can install the audio equipment so that the performance as the audio equipment can be efficiently exhibited. In the headrest device, an impact-resistant surface is formed on a core material of the headrest main body, an opening is formed on the impact-resistant surface, and a non-contact acoustic microphone is disposed inside the opening.

Description

technical field [0001] The present invention relates to a headrest device and a sound collecting device. Background technique [0002] Conventionally, there has been known a headrest device in which a vibration pickup type microphone (microphone) is provided on a headrest of a seat to detect the voice of a seated person based on a bone conduction signal (for example, refer to Patent Document 1). [0003] prior art literature [0004] Patent Literature [0005] Patent Document 1: Japanese Patent Laid-Open No. 2004-83004 [0006] However, in the headrest device, there is a standard that the impact when the head of the seated person presses the headrest must be set to a predetermined value or less. If a microphone as an audio device is provided near the front surface of the headrest, since the audio device may hit the head and cause an impact, it is difficult to satisfy the above-mentioned standard. In addition, it is also desired to install the audio equipment on the headr...
